Start Claude Code

Start the container as a daemon

docker compose -f docker-compose.claude.yml up -d

Then connect via cmux (once the SSH stack ships)

cmux ssh claude@localhost -p 2222

Build first (not needed, just do it manually)

Build with latest everything (only rebuilds layers where versions changed)

./build.sh

Or pin a specific version

CLAUDE_VERSION=2.1.31 ./build.sh

Run Docker (legacy via run)

For good signal handling, terminal resizing and using PID 1 use the following run command: docker compose -f docker-compose.claude.yml run --service-ports --rm -it claude claude

OR

docker compose -f docker-compose.claude.yml run --service-ports --rm -it claude claude --dangerously-skip-permissions --verbose

Add a project name for task sharing between instances CLAUDE_CODE_TASK_LIST_ID=my-project claude

Run a side instance:

docker compose -f docker-compose.claude.yml exec claude claude

Enter through bash alongside claude code through this command:

docker compose -f docker-compose.claude.yml exec --user claude claude bash

Temporary stale LSP fix dropping diagnostics entirely

Claude Code Viewer Dashboard

NODE_ENV=production bunx @kimuson/claude-code-viewer@latest --hostname 0.0.0.0 --port 3400 --claude-dir ~/.claude

CCUsage statusline

Add to settings.json { "statusLine": { "type": "command", "command": "bun x ccusage statusline", "padding": 0 } }

Language Server Protocol (LSP)

Activate through ENV

ENABLE_LSP_TOOL=1

Install language server

TypeScript

npm install -g typescript-language-server typescript

Python

pip install python-lsp-server # or pip install pyright

Go

go install golang.org/x/tools/gopls@latest

Rust

rustup component add rust-analyzer

Add .lsp.json to root

{
  "typescript": {
    "command": "typescript-language-server",
    "args": ["--stdio"],
    "extensionToLanguage": {
      ".ts": "typescript",
      ".tsx": "typescriptreact"
    }
  },
  "python": {
    "command": "pylsp"
  }
}

replace pylsp with pyright-langserver for pyright

TweakCC

Theme editor

bunx tweakcc

Apply tweakcc patches

bunx tweakcc --apply

Setup LSP inside Claude Code

Add marketplace

/marketplace add https://github.com/Piebald-AI/claude-code-lsps

Install plugins

/plugin install vtsls@claude-code-lsps # JavaScript/TypeScript /plugin install pyright@claude-code-lsps # Python /plugin install phpactor@claude-code-lsps # PHP /plugin install sourcekit-lsp@claude-code-lsps # Swift (if installed)

Important Notes

• Official vs Community: Based on the search results, the official LSP support has some issues (plugins not being recognized properly). The community approach with tweakcc is reported to be more robust.
• Swift Complexity: Swift LSP requires the full Swift toolchain (~1GB+), which significantly increases image size. Consider if you really need it.
• Plugin Configuration Persistence: Plugin installations create files in ~/.claude/. You might want to volume mount this directory or create a setup script that runs on container start.
• Verification: After setup, you can verify LSP is working by asking Claude to use features like "go to definition" or "find references" in your code.
