Claude Code Docker

Run multiple Claude Code accounts simultaneously on macOS.

macOS Claude Code stores auth in the system Keychain, so only one account can be logged in at a time. Running Claude Code in Docker gives each container its own isolated filesystem — point each container at a different config directory to run multiple accounts simultaneously.

Setup

1. Build the image

make build

2. Add shell functions to your .zshrc or .bashrc

Create one function per account. Each function maps a different host directory to /root/.claude inside the container, keeping credentials fully isolated.

# Personal account
claude-personal() {
  local profile="personal"
  docker run -it --rm \
    -e YOLO=0 \
    -v "$HOME/.claude-${profile}-docker:/home/claude/.claude" \
    -v "$HOME/.claude-${profile}-docker.json:/home/claude/.claude.json" \
    -v "$(pwd):/workspace" \
    claude-code-docker:latest "$@"
}

# Work account
claude-work() {
  local profile="work"
  docker run -it --rm \
    -e YOLO=0 \
    -v "$HOME/.claude-${profile}-docker:/home/claude/.claude" \
    -v "$HOME/.claude-${profile}-docker.json:/home/claude/.claude.json" \
    -v "$(pwd):/workspace" \
    claude-code-docker:latest "$@"
}

3. Reload your shell

source ~/.zshrc

Usage

Navigate to any project directory and run the account you want:

cd ~/projects/my-personal-project
claude-personal

cd ~/projects/work-project
claude-work

Each account logs in independently and stores its credentials in its own directory (~/.claude-personal-docker or ~/.claude-work-docker). After the first login, subsequent runs start immediately without re-authenticating.
