Docker Releases Guide on Three File Organization Methods for Coding Agent Checkouts

On 2 November 2026, Docker published a blog post titled Where should your code live in a Docker Sandbox?, written by David Karlsson. The post appeared at docker.com/blog/docker-sandbox-code-checkout-workflows, and a DEV Community AI piece that covered it was captured on 3 November 2026, before being surfaced on 7 November 2026.

The article explains that a Docker Sandbox is an isolated environment where a coding agent runs its tools and edits files, with its own filesystem and its own view of git. It walks through three ways to place the code an agent works on. In the first, a shared mount from the host, the agent edits the working tree you already have open and startup is the fastest, though the trade-off is that the agent shares the checkout with everything else running on the host. The second approach uses a linked git worktree per task, giving each task its own working tree that stays in sync with the repository. The third is clone mode, also called mountless mode, where the repository lives inside the sandbox and the agent works on a full clone.

The guide is aimed at teams that pair human review with coding agents and need to pick a checkout workflow accordingly. The materials available cover the publication of the guide and its description of the three workflows, with no further developments reported since.
