docker-build
Build Docker images with proper tagging, cache busting, and build tracking. Prevents stale image issues.
Best use case
docker-build is best used when you need a repeatable AI agent workflow instead of a one-off prompt.
Build Docker images with proper tagging, cache busting, and build tracking. Prevents stale image issues.
Teams using docker-build should expect a more consistent output, faster repeated execution, less prompt rewriting.
When to use this skill
- You want a reusable workflow that can be run more than once with consistent structure.
When not to use this skill
- You only need a quick one-off answer and do not need a reusable workflow.
- You cannot install or maintain the underlying files, dependencies, or repository context.

# Docker Build with Tracking
Build a Docker image with proper tagging and tracking: $ARGUMENTS
## Process
1. **Determine the image tag** - Use git SHA or timestamp, NEVER use `:latest` alone
```bash
GIT_SHA=$(git rev-parse --short HEAD)
TIMESTAMP=$(date +%Y%m%d-%H%M%S)
TAG="${GIT_SHA}-${TIMESTAMP}"
```
2. **Build with cache busting when needed**
- For production builds: `docker build --no-cache --pull -t <registry>/<image>:${TAG} .`
- For dev builds: `docker build -t <registry>/<image>:${TAG} .`
- Always also tag as `:<branch>-latest` for convenience
3. **Verify the build**
```bash
docker images | grep <image>
docker inspect <registry>/<image>:${TAG} | jq '.[0].Created'
```
4. **Push to registry**
```bash
docker push <registry>/<image>:${TAG}
docker push <registry>/<image>:<branch>-latest
```
5. **Verify in registry**
```bash
# For ACR:
az acr repository show-tags --name <registry> --repository <image> --orderby time_desc --top 5
# For Docker Hub:
docker manifest inspect <registry>/<image>:${TAG}
```
## Anti-Patterns (DO NOT)
- Never build with just `:latest` tag
- Never skip pushing after building
- Never deploy without verifying the image exists in the registry
- Never use `imagePullPolicy: IfNotPresent` with mutable tagsRelated Skills
