dsh-docker

The Docker MCP ecosystem is expanding quickly, yet day-to-day operations remain fragmented: starting and stopping the MCP Gateway, adding and removing dozens of servers in a profile, searching and deploying from the official Catalog, managing container lifecycles and image cleanup - these tasks usually live across multiple terminal windows, SSH sessions, and documentation tabs. dsh-docker consolidates all of them into a single sidebar panel inside the DeepSeek Harness Web GUI. An MCP tab (Deployed and Catalog sub-pages) sits alongside a Containers and Images tab, with a target selector at the top that switches between the local CLI and a remote SSH host in one click, so every action immediately points at the correct daemon without opening a new shell or retyping an address.

Security is handled end to end: the panel HTTP server binds to loopback only, SSH passwords are encrypted at rest with Windows DPAPI and never written in plain text, container IDs, image names, ports, and paths are validated against allow-list regexes before being interpolated into any command, and every destructive operation (stop, restart, delete, prune) triggers a two-step confirmation. An interactive terminal supports docker exec -it sessions over SSH with full PTY and window-resize capability. Quality-of-life details such as batch image deletion, dangling-image cleanup by ID, and a default keep-alive for newly created containers cover the high-frequency tasks that are easy to botch in a real workload.

The plugin is aimed at developers and SREs who already use the DeepSeek Harness Web GUI, work with the Docker MCP Gateway regularly, and juggle both a local dev machine and one or more remote servers. It does not replace docker CLI or Docker Desktop; it simply saves you a few windows and a few copy-paste cycles while you are already working in the browser.
