What is the rollback strategy for Base images?

Rollback strategy for base images is crucial in software development and deployment. A rollback allows teams to revert to a previous version of a base image quickly, ensuring stability and minimizing downtime. Here’s an outline of a rollback strategy for base images:

  1. Version Control: Maintain version control for your base images. Tag images with meaningful version names (e.g., v1.0, v1.1) for easy reference.
  2. Testing: Before deploying a new base image, thoroughly test it in a staging environment to catch potential issues early.
  3. Automated Backups: Automatically capture and store the most recent base images to a secure storage solution before deploying new changes.
  4. Rollback Plan: Define a clear rollback plan that outlines the steps to revert to a previous version of the base image in case of failure.
  5. Monitoring: Implement robust monitoring to detect issues post-deployment, allowing for prompt rollback if necessary.

By following these steps, teams can effectively manage base image versions and ensure a streamlined process for rolling back in case of issues.

// Example of tagging a Docker image $dockerImage = 'my-base-image:latest'; shell_exec("docker tag $dockerImage my-base-image:v1.0"); // Deploy the new image shell_exec("docker push my-base-image:v1.0"); // If issues arise, rollback to previous version shell_exec("docker run --rm my-base-image:v1.0");
