Install Kubernetes Ephemeral Job in Goose

What you need first

• Goose, installed.
• Docker, which gives the docker command the server starts with.
• Your own value for YOUR_MCP_K8S_ALLOWED_IMAGES.

Steps

1. Open ~/.config/goose/config.yaml. On Windows it is %APPDATA%\Block\goose\config\config.yaml.
2. Add this entry. If the file already has extensions, add only the entry inside it.

extensions:
  "mcp-k8s-ephemeral-job":
    type: stdio
    name: "mcp-k8s-ephemeral-job"
    enabled: true
    cmd: "docker"
    args: ["run", "-i", "--rm", "-e", "MCP_K8S_ALLOWED_IMAGES", "docker.io/idconstruct/mcp-k8s-ephemeral-job:v0.7.1"]
    env_keys: []
    envs: { "MCP_K8S_ALLOWED_IMAGES": "YOUR_MCP_K8S_ALLOWED_IMAGES" }
    timeout: 300

3. Replace YOUR_MCP_K8S_ALLOWED_IMAGES with your own value.
4. Save the file and start a new Goose session.

Check it worked

Ask Goose: List the tools of mcp-k8s-ephemeral-job.

If it does not start

Cannot connect to the Docker daemon

Docker is not running. Start it, then restart Goose.

The server starts, but its tools fail

A YOUR_… placeholder is still in the config, or its value is wrong.

Nothing changes after a restart

The file is not valid YAML any more. Check that the entry is indented like the lines around it.
