sbx/docker-agent-image repository overview

⁠sbx/docker-agent-image

Base image for the Docker Agent kit for Docker Sandboxes⁠.

⁠Contents

Built on docker/sandbox-templates:shell-docker: the standard sandbox tool chain plus a Docker engine, requesting Docker-in-Docker via com.docker.sandboxes.start-docker=true. On top of that:

• docker-agent, Docker's agentic coding CLI, installed from its GitHub release into /opt/docker-agent/bin/docker-agent, with /usr/local/bin/docker-agent as a symlink to it

The /opt location is owned by the agent user so the agent's in-place self-update can rewrite its own binary.

Build args:

• BASE_IMAGE — re-point or digest-pin the base.
• DOCKER_AGENT_VERSION — pin a release tag (vX.Y.Z). Left empty, the build resolves the newest release from the GitHub API, which is an unauthenticated call and can be rate-limited on a busy runner.
• TARGETARCH — supplied by BuildKit; selects the release asset.

Runs as the non-root agent user, with CMD ["docker-agent"].
