The following is a summary of changes in this pull request made by me, your security buddy :robot:. Note that this summary is auto-generated and not meant to be a definitive list of security issues but rather a helpful summary from a security perspective.

Summary:

The code changes in this pull request are focused on improving the security and efficiency of the Docker images used for the client, migration, and agent components of the application. The key changes include:

1. Base Image Updates: The base images for the builder and final stages have been updated to use more secure and minimal base images, such as cgr.dev/chainguard/go:latest and scratch. This reduces the attack surface and potential vulnerabilities in the underlying base image.

2. Non-Root Execution: All the Dockerfiles are set to run the application binaries as a non-root user (user ID 65532), which is a recommended security practice to minimize the potential impact of any vulnerabilities or misconfigurations in the container.

3. Minimal Final Images: The use of the scratch base image for the final container stages results in extremely lightweight and secure Docker images, as they only contain the compiled application binaries and no other unnecessary components.

From an application security perspective, these changes are generally positive and help to improve the overall security posture of the application's Docker images. The choice of base images, the use of non-root execution, and the minimalist final images all contribute to reducing the attack surface and potential vulnerabilities in the deployed containers.

Files Changed:

• dockerfiles/client/Dockerfile: The base image for the builder stage has been changed to cgr.dev/chainguard/go:latest, and the final stage uses the scratch base image, resulting in a highly secure and efficient Docker image.
• dockerfiles/migration/Dockerfile: The base image for the builder stage has been changed to cgr.dev/chainguard/go:latest, and the final stage uses the cgr.dev/chainguard/wolfi-base image, which is likely a more secure and minimal base image.
• dockerfiles/agent/git/Dockerfile: The base image has been updated to cgr.dev/chainguard/go:latest, and the final container runs the agent binary as a non-root user.
• dockerfiles/agent/container/Dockerfile: The base image has been updated to cgr.dev/chainguard/go:latest, and the final container uses the scratch base image and runs the agent binary as a non-root user.
