Setting Up a Pipeline in GitLab
Prerequisites
Before diving into the setup process, make sure you have the necessary prerequisites in place. This includes an Ubuntu 22 server with root privileges or a user with sudo permissions, at least 4GB of RAM for optimal performance, and a domain name pointing to your server (optional but recommended). If you’re using GitLab Premium, ensure that all the necessary dependencies are installed before proceeding with the setup. For a quick reference, here’s a table summarizing the prerequisites:
| Prerequisite | Description |
|---|---|
| Ubuntu 22 Server | Required for hosting GitLab |
| Root Privileges or User with Sudo Permissions | Necessary for system-level operations |
| 4GB RAM | Optimal performance requirement |
| Domain Name | Optional but recommended for server accessibility |
Remember, these prerequisites are essential for a smooth setup process, especially when working with GitLab Premium.
Creating a New Project
To create a new project in GitLab, navigate to the dashboard and click on the ‘New Project’ button. Enter the project name, description, and choose the visibility level. You can also initialize the repository with a README file and add a .gitignore file for your preferred programming language. Once the project is created, you can start adding files, code, and collaborating with team members. Remember to set up the project’s permissions and webhooks for efficient development processes.
Configuring the Pipeline
Now provide all the required configuration and build it. You can also configure variables, triggers as part of building the pipeline. You can now save and run the pipeline. Choose a template that builds your kind of application. Use the classic editor to create a pipeline without YAML. Let’s use the classic editor, click on this classic editor as shown below. Let us suppose we are using Azure Repos Git as source, select the Team project, Repository, and the branch from the drop down as shown below. Click on continue. Create a file named ".gitlab-ci.yml" in the project root directory with the following contents. This defines a basic Terraform pipeline in the GitLab CI/CD platform. GitLab provides this template. If you want to customize this pipeline or create it from scratch
- Implement a table for presenting structured, quantitative data. Ensure it’s succinct and formatted correctly in Markdown.
- Use a bulleted or numbered list for less structured content, like steps, qualitative points, or a series of related items.
Adding AWS Credentials
With your project now in place, it’s time to add AWS credentials to your GitLab pipeline. This is a crucial step to ensure that your pipeline has the necessary permissions to interact with your AWS resources.
To configure AWS credentials in GitLab, follow these steps:
- Go to your project’s
Settings > CI/CD > Variables. - Click on Expand to reveal the variables section.
- Add your AWS Access Key ID and Secret Access Key as new variables. Make sure to mark them as ‘Protected’ and ‘Masked’ to keep them secure.
Tip: Always protect your sensitive keys and secrets. By marking them as ‘Protected’, they will only be available to pipelines running on the protected branches or tags.
Once you’ve added the credentials, trigger a pipeline run to verify that everything is set up correctly. If the pipeline succeeds, you’ll have confirmation that your AWS credentials are properly configured and your GitLab pipeline can now automate software delivery with access to AWS services.
Setting Up the Remote Backend
As discussed in the first section, we left the backend “http” block empty. In fact, when we pushed the code to our GitLab repository for the first time, it automatically triggered the pipeline and also initialized Terraform successfully. GitLab automatically configures the remote “http” backend. The Terraform config is version-controlled in GitLab repositories, the pipelines are run on GitLab runners, and the backend is also managed by GitLab.
To access the remote backend, navigate to “Infrastructure > Terraform.” Here we find the “default” state being managed, as shown in the screenshot below. The state JSON file can also be downloaded and locked manually from here.
We have successfully set up:
- The configuration that creates an EC2 instance.
- CI/CD pipeline that automates the provisioning.
- Remote state backend.
As far as updating and committing the changes to the configuration on the web browser is concerned – all of this works well since everything is managed by GitLab. However, we also have the Terraform configuration files created on the local machine, which need to be managed and updated. To configure the backend for local development, follow these steps:
- Ensure that the Terraform configuration files are properly organized and version-controlled in the local Git repository.
- Set up the local backend configuration to store the state file locally.
- Run the Terraform commands to initialize the backend and configure it for local development.
These steps will ensure that the local development environment is aligned with the remote backend and the GitLab pipeline, allowing for seamless collaboration and development processes.
Implementing Pipeline Conditions
When implementing pipeline conditions, it’s important to ensure that the workflow is structured and efficient. Use italics for subtle emphasis where needed. Implement a table for presenting structured, quantitative data. Ensure it’s succinct and formatted correctly in Markdown. Use a bulleted or numbered list for less structured content, like steps, qualitative points, or a series of related items. Remember to keep the content split into multiple short paragraphs. Additionally, do not use the H3 heading in the paragraph.
Destroying the Pipeline
Once the pipeline has served its purpose and the infrastructure needs to be de-provisioned, it’s important to follow the correct steps to ensure a smooth and efficient process. To manage the destruction of the infrastructure, we can rely on the commit message provided at the time of committing the changes to the repository. This is because that is the last message available before the pipeline is destroyed. Additionally, it’s recommended to run the Terraform destroy command from the local machine to ensure proper de-provisioning. Here’s a simple table to illustrate the steps:
| Step | Description |
|---|---|
| 1 | Commit changes to the repository with a clear and descriptive message |
| 2 | Run Terraform destroy command from the local machine |
Following these steps will help in effectively managing the destruction of the pipeline and associated infrastructure.
