Docker Development Environment

Setup

  1. (Optional) For environment variables, create .env file and add to docker-compose.yml:
# .env file (gitignored)
CLAUDE_API_KEY=your_key_here

Then add to docker-compose.yml under the service:

env_file:
  - .env
  1. Copy your nvim config:
cp -r ~/.config/nvim ./nvim-config
  1. Build and run in background:
docker-compose up -d --build

# Or use a different host port if 5173 is in use:
PORT=5174 docker-compose up -d --build
  1. Enter container:
docker-compose exec iris-dev bash

# Or with zsh if you prefer:
docker-compose exec iris-dev zsh

Available Commands

Inside container:

  • pnpm dev - Run development server
  • pnpm test - Run Playwright tests
  • pnpm lint - Run linter
  • nvim - Neovim with your config
  • claude - Claude CLI (auto-aliased with --dangerously-skip-permissions)

Syncing Changes Without GitHub

Using Git Patches

Export changes from container:

# Inside container - create patch of uncommitted changes
git diff > /tmp/changes.patch

# From host - copy patch out
docker cp $(docker-compose ps -q iris-dev):/tmp/changes.patch ./changes.patch

# Apply patch on host
git apply changes.patch

Quick commands

Add to your ~/.zshrc:

# Extract patch from docker (uncommitted changes)
iris-patch-out() {
  local project=${1:+-p $1}
  docker exec $(docker-compose $project ps -q iris-dev) sh -c "cd /home/developer/iris-client && git diff" > ./changes.patch && \
  echo "Patch saved to ./changes.patch"
}

# Apply patch in docker
iris-patch-in() {
  local project=${1:+-p $1}
  docker cp ./changes.patch $(docker-compose $project ps -q iris-dev):/tmp/changes.patch && \
  docker exec $(docker-compose $project ps -q iris-dev) sh -c "cd /home/developer/iris-client && git apply /tmp/changes.patch"
}

# Pull latest commit(s) from docker and apply to host
iris-commit-pull() {
  local project=""
  local n=1

  # Parse arguments
  while [[ $# -gt 0 ]]; do
    case $1 in
      -n) n=$2; shift 2;;
      *) project="-p $1"; shift;;
    esac
  done

  docker exec $(docker-compose $project ps -q iris-dev) sh -c "cd /home/developer/iris-client && git format-patch HEAD~$n --stdout" | git am
}

# Usage:
# iris-commit-pull                # pull 1 commit from default project
# iris-commit-pull iris2          # pull 1 commit from iris2 project
# iris-commit-pull -n 3           # pull 3 commits from default project
# iris-commit-pull iris2 -n 2     # pull 2 commits from iris2 project
