sbx/shell-image repository overview

⁠sbx/shell-image

Base image for the shell kit for Docker Sandboxes⁠: a sandbox with no agent installed.

It is built from Ubuntu by the kit's own recipe: bash, git, apt, curl, gh, jq, make, build tools, Node with npm, Python 3 with pip, Go, a headless JDK, uv, the non-root agent user with passwordless sudo, and a Docker engine with compose and buildx. It establishes the login-shell prompt and requests Docker-in-Docker through the standard sandbox image label. No agent is installed, and the image declares no credentials of its own; the kit does that.

Most toolchain versions come from Ubuntu's archive at build time. Docker packages come from download.docker.com, and GitHub CLI comes from cli.github.com. Go, uv and the clipboard bridge are pinned in the recipe; GitHub CLI must be at least 2.102.1. CI rebuilds the image nightly.
