Motivation

Integration tests and local builds store tens of gigabytes of images and BuildKit cache on the Docker host. Pointing Docker at another machine keeps that data off the laptop, but nothing explained which env vars to set or how to confirm the CLI is talking to that host.

Description

  • Document setting DOCKER_HOST (or DOCKER_CONTEXT) in an untracked mise.local.toml so the existing BuildKit container helper talks to a remote daemon.
  • Include the SSH/setup caveats and docker info / docker context inspect commands to see which host is live.
  • Ignore mise.local.toml so local host overrides are not committed.
