This documentation provides a detailed step-by-step guide on how CI/CD is deployed with the Thanos project. Currently, the CI/CD system for the Thanos project is not yet set up. Below are the recommended next steps for establishing a CI/CD pipeline using the project’s existing tools and methodologies.

Current Status

As of now, there is no continuous integration and continuous deployment (CI/CD) strategy established within the Thanos repository. However, the repository does contain various scripts and configurations that can be leveraged to create an effective CI/CD pipeline.

Recommended Next Steps

1. Choose a CI/CD Platform:

   • Popular options include CircleCI, GitHub Actions, GitLab CI, and Travis CI. Based on the previous usage in the project, CircleCI may be a suitable option given its mentioned integration.

2. Define CI/CD Workflows:

   • Create a basic workflow that includes steps for code validation (linting, testing), building Docker images, and deploying to appropriate environments.

3. Utilize Makefile:

   • The project’s Makefile contains various target commands for building and testing which can be integrated into the CI/CD pipeline.
   • An example target from the Makefile:

     test:
         go test ./... -tags '!linux,!stringlabels'
     

4. Implement Docker Builds:

   • The Dockerfile already defined in the project can be used to construct container images. Use the Makefile to automate Docker tasks, like so:

     docker-build:
         docker build -t thanos:latest .
     

5. Automated Testing:

   • Ensure that tests are run as part of the pipeline. Use the CLI as specified:

     go test ./... -tags '!linux,!stringlabels'
     

6. Release Process:

   • Follow the outlined release process when tagging and pushing new releases to ensure the CI/CD pipeline can create releases seamlessly:
     • Create a GitHub release immediately after tagging, as:

       git tag vX.Y.Z
       git push origin vX.Y.Z
       

     • Trigger CircleCI for automated tasks using:

       circleci build
       

7. Setup Environment:

   • Set up containerized environments using Docker as defined in the Dockerfile and orchestrate deployments via scripts or configuration files.

Example Scripts and Commands

Running Tests

To execute tests while adhering to the specified build constraints, use:

go test ./... -tags '!linux,!stringlabels'

Building Docker Images

You can build the Docker image using the following Make command:

make docker-build

Pushing to Container Registry

Add a target to your Makefile to facilitate pushing Docker images:

docker-push:
    docker push thanos:latest

Deploying Documentation

Infrastructure for documentation can be included as part of deployment processes. Implement the following in build scripts:

bash scripts/website/websitepreprocess.sh

Conclusion

Setting up a CI/CD process for the Thanos project requires strategic use of existing tools, scripts, and configuration files that are present within the repository. Follow the outlined steps to create a robust and efficient deployment pipeline.

For a starting point, consider incorporating automated testing, Docker image builds, and setting up a release process that syncs with the version control. Over time, this can evolve into a comprehensive CI/CD ecosystem that streamline contributions and deployments for the Thanos project.
