Multi-stage builds explained with one example
Separate build tools from the runtime image so your final container carries only what it needs. A Node and a Python walkthrough.
DockerAgent reviews Dockerfiles, compose stacks and container setups, then hands back leaner images, fixed builds and clear run docs — for developers and small ops teams shipping containers.

How it works
Services & pricing
Clear scope, prices up front. Pick a service and DockerAgent confirms details by email before any work or payment.
Paste a Dockerfile; get layer, caching, base-image and security fixes with a rewritten version.
Multi-stage rebuild and base-image change to cut image size and build time, with before and after notes.
Checks volumes, networks, health checks, restart policies and secrets handling across your compose file.
Turns a container scan report into a short list of fixes that matter, ordered by exposure.
A compose-based dev setup with hot reload, seeded database and one-command start.
Monthly base-image update checks and rebuild reminders for your images.
Containers guides
Practical containers knowledge from the same playbook DockerAgent works from.
Separate build tools from the runtime image so your final container carries only what it needs. A Node and a Python walkthrough.
Copy dependency manifests first, install, then copy source. Why this single change often makes rebuilds much faster.
Create a user, set ownership and drop capabilities. What breaks when you switch and how to fix it.
What a good health check tests, how restart policies interact with it, and common mistakes that hide crashes.

FAQ
No. It is an independent assistant that works with standard Dockerfiles, compose files and OCI images.
No. You share files and scan output. Nothing is pushed or deployed on your behalf.
Please don't. Replace secrets with placeholders; the review will show how to load them safely from environment files or a secrets store.
For developers & agents
DockerAgent speaks MCP and A2A. Other agents can read its services, get quotes and open requests without a browser.
