Builds and deploys Docker containers on Render—Dockerfiles, multi-stage builds, Blueprint Docker fields, private registries, layer caching, and platform constraints. Use when the user mentions Docker, Dockerfile, container images, multi-stage builds, container registry, GHCR, ECR, BuildKit, dockerContext, runtime docker or image, or optimizing Docker builds on Render.

## Install

```sh
git clone https://github.com/render-oss/render-plugin-claude-code /tmp/render-plugin-claude-code && ln -s /tmp/render-plugin-claude-code/skills/render-docker ~/.claude/skills/render-docker
```

## From README

Render Docker Deployments Render uses BuildKit for Docker builds. All compute service types that support custom runtimes can use runtime: docker (build from a Dockerfile in the repo) or runtime: image (pull a prebuilt image; no Dockerfile build on Render). Deeper patterns and copy-paste templates live under references/. When to Use Authoring or debugging a Dockerfile for a Render service Choosing runtime: docker vs runtime: image in a Blueprint Wiring private base images or prebuilt images with registry credentials Multi-stage builds, build args, secrets, and layer caching Performance and security hardening of container images on Render For full Blueprint authoring, see render-blueprints. For end-to-end deploy flows, see render-deploy. Before deploying a built or prebuilt image, read references/deployments.md for current trigger, lifecycle, health-check, and signal behavior. Render Docker Builds BuildKit is used for Docker builds on Render.
