Remember, redundancy is not just about having copies; it’s about ensuring those copies can be effectively utilized when needed. By following these steps, you can confidently proceed with the shutdown process, knowing your data is secure.

Securing Data Before Shutdown

Securing Data Before Shutdown

Performing Data Backup

Before shutting down GitLab, it’s crucial to ensure that all your data is safely backed up. Start by navigating to your GitLab installation directory and executing the backup command as the GitLab user. This process will create a backup of the entire GitLab system, which includes repositories, databases, and configurations.

Ensure that your backup is comprehensive by verifying that all critical data is included. This might involve checking the backup logs to confirm that each repository and database has been successfully saved. Additionally, consider the redundancy of your backups. It’s advisable to store backups in multiple locations to prevent data loss in case of a failure in one storage site.

Remember to configure your backup system to allow for recovery in different regions if necessary. This is especially important when using cloud services, as backups are often tied to specific geographic locations.

To streamline the backup verification process, you can use the following checklist:

  • Verify that the backup includes all GitLab components.
  • Check the backup logs for any errors or warnings.
  • Confirm the integrity of the backup files.
  • Ensure backups are stored in multiple, geographically diverse locations.

Validating Backup Integrity

After performing a data backup, it’s crucial to validate the integrity of the saved state. Ensure that the backup is not corrupted and that it accurately reflects the current state of your GitLab environment. This step is essential for a reliable restoration process, should the need arise.

To verify the integrity of your backup, follow these steps:

  1. Check the backup logs for any errors or warnings that occurred during the backup process.
  2. Use checksums or hash values to confirm that the backup files are complete and unaltered.
  3. Perform a trial restoration on a separate system to ensure the backup can be successfully deployed.

Remember, a backup is only as good as its last validation. Regularly scheduled integrity checks are a best practice to maintain the reliability of your backups. GitLab ensures security and compliance by implementing access controls, managing secrets securely, and providing audit trails for credential access.

Exporting Critical Configurations

Before shutting down your GitLab instance, it’s crucial to export critical configurations to ensure a smooth restoration or migration if needed. Exporting configurations safeguards your environment’s setup, including system settings, CI/CD variables, and feature flags. Start by identifying the configurations that are essential for your operations. These typically include:

  • CI/CD pipeline settings
  • Environment variables
  • Integration tokens and keys
  • Feature flag settings

Use GitLab’s built-in export tools or scripts to extract these configurations. Ensure that you store the exported files in a secure, yet accessible location. It’s also wise to keep a record of the export process, detailing what was exported and when.

Remember, the goal is to create a comprehensive snapshot of your system’s state that can be readily re-imported or referenced in the future.

Validate the integrity of the exported data. This step is non-negotiable as it ensures that the configurations you rely on are complete and uncorrupted. A simple way to validate is by importing the configurations into a test environment or by using checksums to verify file integrity. Lastly, consider encrypting sensitive information within the configuration files to protect credentials and other private data during storage and transit.

Stopping GitLab Services

Stopping GitLab Services

Gracefully Stopping GitLab Components

When it’s time to halt your GitLab instance, it’s crucial to do so without disrupting ongoing processes. Ensure all users have committed their changes and are aware of the impending downtime. For GitLab Premium customers, the platform offers advanced features to manage shutdowns more effectively.

  • Notify all users about the scheduled maintenance and confirm their acknowledgment.
  • Check for active pipelines and jobs, and wait for them to finish or stop them manually.
  • Use the gitlab-ctl stop command to stop GitLab services one by one, starting with non-critical services.

Remember, a graceful shutdown minimizes the risk of data corruption and ensures a smoother restart.

After executing these steps, verify that all components have indeed stopped. This can be done by checking the service status or by looking at the system’s resource utilization. A clean shutdown now will save you from potential headaches when GitLab is brought back online.

Verifying Service Termination

After initiating the shutdown of GitLab services, it’s crucial to verify that all processes have indeed terminated. This step ensures that no lingering processes continue to run, which could lead to data corruption or conflicts upon a future restart. Use the following checklist to confirm service termination:

  • Check the process list for any GitLab-related processes.
  • Review system logs for shutdown confirmations or errors.
  • Ensure that no traffic is being routed to the instance.

If any processes are still running after the grace period, they may receive multiple SIGTERMs. In such cases, consult the GitLab documentation on troubleshooting to understand the appropriate steps to take.

It is essential to allow applications the time to shut down cleanly. This typically involves a 30-second window where processes should cease accepting new requests and complete any ongoing tasks. If processes do not terminate within this window, they will be forcefully stopped.

Remember to adjust settings like spring.lifecycle.timeout-per-shutdown-phase to align with your termination grace period, ensuring a smooth shutdown sequence.

Handling Persistent Sessions

When shutting down GitLab, it’s crucial to handle persistent sessions to prevent data loss and ensure a smooth transition for users upon restart. Ensure all user sessions are properly terminated to avoid any inconsistencies or security issues. This involves clearing session-related data and revoking session tokens.

Graceful termination of sessions is key. You may need to adjust settings such as spring.lifecycle.timeout-per-shutdown-phase to allow for a proper shutdown period. This ensures that all transactions are completed and no session is left in a half-open state.

Remember to document the session handling process. This will be invaluable for verifying the shutdown procedure and for future reference.

Here’s a checklist to follow:

  • Notify users about the impending session termination.
  • Increase the termination grace period if necessary.
  • Clear session caches and temporary data.
  • Revoke any active session tokens.
  • Confirm that no new sessions can be initiated.

Disabling Network Access

Disabling Network Access

Configuring Firewall Rules

When preparing to shut down GitLab, it’s crucial to ensure that no new connections can be made to the system. Configuring firewall rules is a key step in this process. Start by identifying the ports that GitLab services are running on. Common ports include HTTP (80), HTTPS (443), and SSH (22). Adjust your firewall settings to block incoming traffic to these ports.

For instance, if you’re using iptables, you might use a command like:

iptables -A INPUT -p tcp --dport 80 -j REJECT
iptables -A INPUT -p tcp --dport 443 -j REJECT
iptables -A INPUT -p tcp --dport 22 -j REJECT

Remember to also handle any custom ports or configurations specific to your environment. If your GitLab instance is behind a router, ensure that port forwarding is disabled to prevent WAN access.

It’s essential to verify that the new firewall rules are active and effective before proceeding with the shutdown. This step prevents any new user sessions from being established and secures the system against unauthorized access during the shutdown process.

Revoking External Access

Once downtime has been announced and dependencies checked, it’s crucial to revoke external access to ensure no new connections can interfere with the shutdown process. This involves disabling any public endpoints and ensuring that services like Nginx, which may act as a reverse proxy, are configured to stop forwarding requests to GitLab.

Ensure that all external access points are disabled to prevent unauthorized access during the shutdown.

For instance, if you’re using Nginx as a reverse proxy, you might have a configuration similar to the one mentioned in a user’s query about setting up GitLab behind Nginx. It’s essential to modify or disable such configurations to cut off access. Here’s a checklist to guide you through the process:

  • Review and update firewall rules to block incoming traffic.
  • Disable any port forwarding rules that may exist.
  • Temporarily remove or comment out relevant sections in your Nginx configuration files.
  • Restart services like sshd to apply changes to SSH access, ensuring you revert any specific GitLab-related configurations.

Remember to document each step taken to revoke access, as this will be critical for maintaining a record of the shutdown procedure and for any potential future audits.

Securing SSH and HTTP Endpoints

Securing your GitLab instance’s SSH and HTTP endpoints is crucial for maintaining the integrity of your data and the privacy of your communications. Ensure that all traffic to and from your GitLab server is encrypted by modifying the necessary configuration files to enforce HTTPS. For instance, update /etc/webapps/gitlab/shell.yml and /etc/webapps/gitlab/gitlab.yml to reflect the secure https:// protocol and set the https: setting to true.

When it comes to SSH, it’s important to verify that your server’s SSH configuration is tight. This includes ensuring that secret keys, such as those found in /etc/webapps/gitlab/secret and /etc/webapps/gitlab-shell/secret, are properly secured and access is restricted to authorized personnel only. Authentication tokens and other sensitive data must be protected to prevent unauthorized access.

Remember to review and update firewall rules to complement the security measures taken within GitLab. Restricting ingress to only necessary services and using advanced network security practices like VPC Service Controls can greatly enhance your security posture.

Lastly, if you’re using Let’s Encrypt for SSL certificates, make sure that the validation process is not hindered by your configurations. Requests to the .well-known subdirectory should not be proxied to GitLab Workhorse, and the Certbot’s "webroot" method can be employed for a smooth validation.

Cleaning Up Resources

Cleaning Up Resources

Removing Temporary Files

As part of the cleanup process, it’s crucial to remove temporary files that GitLab and associated processes have generated. These files can consume unnecessary disk space and may contain outdated information that could cause confusion if not cleared before a shutdown. Ensure that all temporary files, especially those in system directories like /tmp, are deleted. This can be done using automated scripts or manual commands, depending on your environment’s setup.

To avoid potential data loss, verify that no important data is stored in temporary locations. Temporary files generated by processes such as backups or updates should be handled with care. For instance, the VERBOSITY option in certain scripts controls the level of detail in email reports, and by default, the full report is stored in /tmp/snapRAID.out. Remember to check for any retention policies that may keep logs for a set number of days and adjust the folder location if necessary.

It’s essential to maintain a clean state in the temporary directories to prevent any residual data from affecting the system post-shutdown.

Finally, review the temporary file cleanup process to ensure completeness. Here’s a checklist to guide you through the process:

  • Confirm deletion of all temporary files in /tmp and other system directories.
  • Check for and preserve any logs or data that may be required post-shutdown.
  • Adjust script settings, such as VERBOSITY, to prevent excessive data generation in the future.

Clearing Cache

After securing data and stopping services, clearing the cache is a crucial step to ensure that no sensitive information remains accessible and to free up system resources. Flush all cache mechanisms in place, including web server caches, application-level caches, and any distributed caching systems you might be using.

GitLab caches can be cleared using the provided rake tasks. For instance, to clear the Redis cache, which GitLab uses for caching and queuing, run the following command:

gitlab-rake cache:clear

Remember, clearing the cache will not affect your data or configurations, but it will temporarily impact the performance as the cache is rebuilt.

Here’s a checklist to ensure all cache layers are addressed:

  • Clear web server cache (e.g., Nginx, Apache)
  • Clear GitLab’s built-in cache mechanisms
  • Invalidate any CDN caches if applicable
  • Clear persistent session data if stored in cache

By methodically clearing the cache, you’re taking an important step towards a clean and controlled shutdown process.

Freeing System Memory

After ensuring that all temporary files and caches have been cleared, the next critical step is to free up system memory. This is essential to prevent any potential memory leaks or unnecessary resource consumption that could affect other services or the system’s stability post-shutdown.

To effectively free system memory, follow these steps:

  1. Identify any processes that are still consuming significant memory using tools like top or htop.
  2. Close these processes gracefully to ensure that all memory they are using is released back to the system.
  3. If applicable, clear any swap space that may have been used. This is especially important in environments where swap space is not automatically managed.

Remember, freeing up memory is not just about reclaiming resources. It’s about leaving the system in a state that is clean, stable, and ready for whatever comes next.

In cases where memory usage is not immediately reclaimed, consider restarting the system to ensure all memory allocations have been completely reset. This is often the most reliable way to restore system resources to their baseline state.

Archiving the GitLab Environment

Archiving the GitLab Environment

Documenting System State

Before shutting down GitLab, it’s crucial to document the current system state. This ensures that you have a reference point for the system’s configuration and performance metrics, which can be invaluable for troubleshooting or if a rollback is necessary. Start by capturing the state of all disk arrays and verify the integrity of the snapshots. GitLab simplifies documentation setup with easy account creation, project configuration, and centralized repository management. Automated deployment and data integration enhance collaboration and efficiency.

Next, record the status of all services and their dependencies. This includes noting down the Required-Stop and Default-Start sections from the INIT INFO to understand the services’ boot and shutdown sequence. Additionally, ensure that you have a list of all running processes, open ports, and scheduled tasks.

It’s essential to maintain a comprehensive log of all system alerts and configurations. This log should include any recent changes made to the system and any alerts that could indicate potential issues.

Finally, update your configuration management databases with the latest system state and send out alerts to IT service management workflows to inform them of the impending shutdown. This proactive communication helps in maintaining transparency and aids in a smoother transition during the shutdown process.

Archiving Logs and Metrics

Archiving logs and metrics is a critical step in preserving the operational history of your GitLab environment. Ensure that all logs and metrics are collected from various components such as the GitLab Rails application, GitLab CI, and any other services that were in use. This includes not only the application logs but also system logs, audit logs, and any custom logs you may have configured.

To streamline the archiving process, consider categorizing logs based on their type and source. For example:

  • Application logs
  • System logs
  • Audit logs
  • Custom logs

It’s essential to verify that the logs are complete and uncorrupted before archiving. Incomplete or corrupted logs can significantly hinder future analysis or troubleshooting efforts.

Once categorized, compress and securely transfer the logs to a designated storage solution. Ensure that the storage solution is reliable and that access is restricted to authorized personnel only. Remember to document the archiving process, including the storage locations and any relevant configurations, to facilitate easy retrieval when needed.

Storing Environment Snapshots

When shutting down GitLab, it’s crucial to capture the state of your environment. Storing snapshots ensures that you have a reference point for the system’s last known good configuration. This can be invaluable for troubleshooting or if a rollback is necessary post-shutdown.

To effectively store environment snapshots, follow these steps:

  • Ensure all services are in a stable state before capturing the snapshot.
  • Use a consistent naming convention for snapshot files for easy identification.
  • Verify the integrity of the snapshot files immediately after creation.

Remember, the goal is to create a comprehensive and reliable record of your environment that can be referred to when needed.

It’s also important to consider the storage location of these snapshots. Secure, off-site storage is recommended to prevent data loss in case of physical damage to the primary site. Automation of this process can save time and reduce the risk of human error, ensuring snapshots are taken at regular intervals without manual intervention.

Maintaining Database Integrity

Maintaining Database Integrity

Flushing Database Transactions

Before shutting down GitLab, it’s crucial to ensure that all database transactions are properly flushed. This step prevents data corruption and ensures that no transactions are left in an uncertain state. Flush your database transactions to safeguard the integrity of your data during the shutdown process.

  • Ensure all active transactions are completed
  • Prevent new transactions from starting
  • Flush all transaction logs

Flushing transactions is a critical step that should not be rushed. Allow sufficient time for this process to complete to avoid any potential data loss.

After flushing, verify that all transactions have been committed to the database. This can be done by checking the transaction logs or using database-specific commands to ensure that the flush was successful. Remember, a clean database shutdown is just as important as a clean service shutdown.

Exporting Database Schemas

Before shutting down GitLab, it’s crucial to export your database schemas to ensure a smooth transition and recovery if needed. Exporting schemas provides a blueprint of your database structure, which is essential for future reference or migration. To export the schemas, follow these steps:

  1. Identify all databases associated with your GitLab instance.
  2. Use the appropriate database management tools to generate schema exports.
  3. Verify the completeness and accuracy of the export files.

Remember to store the exported schemas in a secure location, separate from your regular backups. This redundancy adds an extra layer of protection for your data.

It’s also important to document the export process, including any commands used and the schema version. This information will be invaluable for restoring or replicating the database in the future.

Lastly, ensure that you have the necessary permissions to access and export the database schemas. Without proper access rights, the export process may fail, leading to incomplete data preservation.

Setting Database in Read-Only Mode

Once the database transactions have been flushed, it’s crucial to set the database in read-only mode. This ensures that no new writes can occur, safeguarding the integrity of the data during the shutdown process. Setting the database to read-only mode is a reversible action that can be undone should the GitLab environment need to be brought back online.

To configure the database in read-only mode, you’ll need to modify the database.yml file. Remember, as of GitLab 17.0, you must specify both main: and ci: sections, which should point to the same database. This step is vital for maintaining a consistent state across all database instances.

Ensure that all active sessions are terminated before switching to read-only mode to prevent any potential data loss or corruption.

After setting the database to read-only, verify the configuration by attempting to perform a write operation. If the setup is correct, the operation should be rejected. Here’s a simple checklist to follow:

  • Confirm that the database.yml file has the correct settings.
  • Terminate all active database sessions.
  • Switch the database mode to read-only.
  • Test the read-only configuration by attempting a write operation.

Remember, this is a precautionary measure to maintain data consistency and can be reversed if necessary.

Handling SSL Certificates and HTTPS

Handling SSL Certificates and HTTPS

Revoking SSL Certificates

Once you’ve decided to shut down your GitLab instance, it’s crucial to revoke its SSL certificates to prevent misuse. Revoking certificates is a security best practice when decommissioning any server to ensure that the certificates cannot be used maliciously. To revoke an SSL certificate, you’ll need to access your certificate authority’s (CA) management console or use their command-line tools.

Revocation is not an instantaneous process; it may take some time for the revocation to propagate and be recognized by all clients. Here’s a simple checklist to follow:

  • Contact your CA to initiate the revocation process.
  • Confirm the revocation status through the CA’s interface.
  • Update your server configuration to remove or disable the SSL certificate references.

Ensure that you also remove any references to the SSL certificates from your server configuration files to prevent errors during server restarts or audits.

Remember to update any documentation that references the revoked certificates, as keeping accurate records is essential for maintaining a secure and compliant environment.

Updating GitLab Configurations

Once SSL certificates are handled, it’s crucial to update GitLab configurations to reflect the changes. Ensure that all references to SSL and HTTPS within the GitLab configuration files are updated or removed as necessary. This includes the main gitlab.yml file and any other component-specific configurations such as gitlab-shell/config.yml and nginx/sites-available/gitlab.

For instance, if you’ve disabled SSL, you’ll need to adjust the gitlab-workhorse settings in the Nginx configuration to no longer point to the SSL socket. Here’s a quick checklist to guide you through the process:

  • Verify the gitlab.yml file reflects the current state of SSL usage.
  • Update the gitlab-shell/config.yml to ensure SSH connections are properly managed.
  • Adjust Nginx configurations, particularly the gitlab-workhorse upstream server block.

Remember, incorrect configurations can lead to service disruptions or security vulnerabilities. It’s imperative to validate all changes with a thorough review.

After making the necessary updates, restart GitLab to apply the changes. This will ensure that the service runs with the latest configuration settings.

Disabling Let’s Encrypt Integration

Once you’ve secured your GitLab instance and are ready to proceed with the shutdown, it’s crucial to disable the Let’s Encrypt integration. This step ensures that your domain will no longer attempt to renew SSL certificates, which could lead to errors or unintended access if the server is brought back online without proper configuration.

To disable Let’s Encrypt, you’ll need to modify your GitLab configuration files. Remove or comment out the lines in your Apache or Nginx configuration that include the Let’s Encrypt settings. For example, in Apache, you would look for lines such as Include /etc/letsencrypt/options-ssl-apache.conf and comment them out by adding a # at the beginning of each line.

Ensure that all references to Let’s Encrypt certificates in your configuration are effectively disabled to prevent any automated processes from running.

After making these changes, it’s important to restart the web server to apply the new settings. This can be done with a simple command like sudo service apache2 restart for Apache or sudo service nginx restart for Nginx. Here’s a checklist to follow:

  • [ ] Modify GitLab’s SSL configuration files
  • [ ] Comment out Let’s Encrypt references
  • [ ] Restart the web server

Remember to verify that the changes have been applied successfully and that your server is no longer serving content over HTTPS with Let’s Encrypt certificates.

Final System Checks

Final System Checks

Reviewing Shutdown Logs

After initiating the shutdown of GitLab services, it’s crucial to review the logs to ensure that all processes have been terminated as expected. Logs provide a transparent record of the shutdown sequence and can highlight any issues that may require attention. To streamline this process, consider using a script that generates a clear and concise email report, omitting unnecessary details like a list of changed files for better clarity.

Logs should be checked for errors or warnings that could indicate problems with the shutdown procedure. It’s advisable to have a retention policy in place for these logs, allowing you to refer back to them if needed. For instance, you might configure the system to keep logs for a certain number of days or store them in a specific folder.

Ensure that the logs are easily accessible and readable. A huge and mostly unreadable log file is not only difficult to analyze but also inefficient for quick reviews post-shutdown.

Lastly, integrate notifications with services like Healthchecks.io or messaging platforms such as Telegram and Discord to receive immediate alerts if the logs report any critical issues. This proactive approach can save valuable time in identifying and resolving potential problems.

Confirming Resource Deallocation

Once GitLab services have been stopped, it’s crucial to ensure that all system resources have been properly deallocated. Check for any lingering processes that may still be holding onto memory or CPU cycles. Use system monitoring tools to verify that resources are freed up and no unexpected load is present.

To confirm that resources have been fully released, consider the following checklist:

  • Review system memory and CPU usage.
  • Inspect disk space and verify that no temporary files are consuming space unnecessarily.
  • Check network activity to ensure no background services are still communicating.

It’s essential to validate that the system is not retaining any residual resources. This step safeguards against potential issues when the system is eventually restarted or repurposed.

If discrepancies are found, investigate and resolve them promptly to avoid complications. Documenting the final state of resource allocation can serve as a reference for future shutdowns or maintenance.

Ensuring All Processes Are Down

After initiating the shutdown, it’s crucial to confirm that all GitLab processes have ceased operations. Ensure no rogue processes remain active; these can cause issues upon a potential restart or data corruption. GitLab processes should gracefully terminate within a designated timeframe, typically around 30 seconds. During this period, they must stop accepting new tasks and complete or re-queue any ongoing jobs.

If processes do not shut down as expected, they will receive a forceful termination signal, such as SIGKILL. This is logged as an error, indicating non-compliance with the shutdown protocol. To verify that all processes have indeed stopped, you can use monitoring tools or check the system’s process table.

It’s essential to perform a thorough check for any lingering processes to avoid complications. A clean shutdown ensures a stable system state for future operations.

Here’s a simple checklist to follow:

  • Review system logs for shutdown errors or timeouts.
