Docker Image Optimization
Strategies for reducing builder image size and securing production containers.
When to use
- When operating in the
devops domain.
- When resolving incidents related to docker image optimization.
When not to use
- If the issue requires manual human intervention.
- If the domain does not apply.
Triggers
- Pattern:
docker-image-optimization
- Keywords: devops, docker
Inputs
- Context from the current user session or incident report.
Steps
1. Step 1
Analyze the current Dockerfile for multi-stage build support.
2. Step 2
Move compilation and heavy dependencies to the builder stage.
3. Step 3
Use a distroless or alpine base image for the final runtime stage.
4. Step 4
Clear package manager caches (e.g., apt-get clean or rm -rf /var/cache/apk/*) in the same layer they are installed.
Success signals
- The task is resolved without regressions.
- Logs confirm the procedure was successfully applied.
Failure modes
- Incorrect application of the steps leading to side effects.
Safety notes
- Always verify changes in a staging environment before applying to production.
- Do not execute destructive commands without explicit authorization.
