Docker

What this skill does

Builds, debugs, hardens, and ships Docker containers, images, and Compose stacks. Use when writing or reviewing a Dockerfile, a compose file, or a CI build step; when a container exits instantly, restart-loops, is OOM-killed, hangs on stop, or exits 137/139/127; when a published port is unreachable, containers cannot resolve each other, or requests hang behind a VPN; when the disk fills and `/var/lib/docker` will not prune; when a build is slow, the cache never hits, or fails only in CI; when `exec format error` or a musl-versus-glibc break is the problem; when choosing a base image or a multi-stage layout; when a registry login or pull rate limit fails; when a secret must stay out of image history; and when volumes need backup, restore or a permission fix. Covers Compose traps and Desktop/colima/OrbStack/Podman differences. Not for Kubernetes manifests or cluster scheduling (`k8s`).

Docker is part of the Developer Tools category — developer tools that help your agent write, review, debug, and ship code. You can install it on its own or alongside other developer tools skills from the OpenClaw catalog.

How to install Docker

The easiest path is via the OpenClaw Easy desktop app — one click, no terminal required:

1. Download OpenClaw Easy for macOS or Windows (free, one-click installer, ~30 seconds).
2. Open the in-app Skills panel.
3. Search for docker and click Install.
4. The skill activates automatically when an incoming message matches its description.

Install from the command line

If you already run the OpenClaw CLI, add Docker with a single command:

openclaw skills add docker

This pulls docker from ClawHub and installs it into ~/.openclaw/skills/docker/. Restart the OpenClaw gateway afterwards so the new skill is discovered.

How to use Docker

Once installed, Docker activates on its own: when an incoming message on WhatsApp, Telegram, Slack, Discord, Feishu or Line matches the skill's description, your OpenClaw agent loads it and runs the workflow. You can also trigger it explicitly by describing the task in chat. No extra configuration is required after install.

Turning images into video

Docker works with images. Getting from there to something postable is a separate job: ViralMint — an open-source video pipeline — turns stills into motion — pans and transitions, synced captions, and a vertical export for short-form feeds.

It runs as an MCP server, so an OpenClaw agent can drive it from the same chat you already use: ask for a short, and the render comes back finished. See how to connect a video pipeline to your agent.

Manual install (advanced)

If you prefer manual installation:

1. Click the Download .zip button above to grab docker-1.0.10.zip directly from our S3 mirror.
2. Unzip into ~/.openclaw/skills/docker/ (create the directory if it does not exist).
3. Restart OpenClaw Easy (or the OpenClaw CLI gateway) so the new skill is discovered.
