What's Wrong?

Reopen #15717

I am also having problems with my devcontainer setup. I mounted my .claude folder from the host system, but because the usernames differ, the plugins cannot be loaded within the Docker container.

As a workaround, I created a symlink to the host's home directory inside the container. However, when I add a plugin within the Docker container, it doesn't work in the host environment.

What Should Happen?

The paths to the installed plugins should be relative to the .claude folder.

Error Messages/Logs

Steps to Reproduce

Host System Home directory: /home/blankse/
Docker Container Home directory: /home/node/

devcontainer.json

{
  "mounts": [
    "source=${localEnv:HOME}/.claude,target=/home/node/.claude,type=bind,consistency=cached",
    "source=${localEnv:HOME}/.claude.json,target=/home/node/.claude.json,type=bind,consistency=cached"
  ]
}

Dockerfile

RUN chown -R node:node /usr/local/share
USER node
ENV PATH=$PATH:/home/node/.local/bin
RUN curl -fsSL https://claude.ai/install.sh | bash

Open VS Code in Docker Container and open claude code.
=> Plugins cannot be loaded

Workaround with symlink:

devcontainer.json

{
"containerEnv": {
    "HOST_HOME": "${localEnv:HOME}"
  },
  "postCreateCommand": "bash .devcontainer/post-create.sh",
}

post-create.sh

#!/bin/bash
set -e
sudo ln -s "$HOME" "$HOST_HOME"
