render-docker
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
With your agent
Install OMGSkills skill "render-oss/render-plugin-claude-code:skills/render-docker" into this agent's normal skills directory: call the OMGSkills MCP get_install_plan tool for your agent and run the script it returns (it installs only the pinned commit and verifies SKILL.md), and stop if MCP or the pin is unavailable. Do not overwrite or change existing skills without asking me.
Manual command
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-dockerFrom 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.
