A dockerfile image that sets up Opencode with Oh-My-Opencode alongside Bun and PNPM

Dockerfile

# Build the image with: docker build -t super-opencode .
# Run the container with: docker run -it --volume="$PWD:/app" --workdir="/app" super-opencode

# Use the official Node.js image based on Debian Bullseye (slim version for smaller size)
FROM node:24.13.1-bullseye-slim

# Set the working directory inside the container to /app
WORKDIR /app

# Install system dependencies required for building and running various tools
# git: version control, curl: downloading files, make/g++: compiling native modules, unzip: extracting archives
# ca-certificates: ensuring secure SSL connections
# We clean up the apt cache afterwards to keep the image size small
RUN apt-get update && apt-get install -y \
    git \
    curl \
    make \
    g++ \
    unzip \
    ca-certificates \
    && rm -rf /var/lib/apt/lists/*

# Install the Bun runtime using the official installation script
RUN curl -fsSL https://bun.sh/install | bash

# Enable Corepack to manage package managers like pnpm and yarn
RUN corepack enable pnpm

# Install the opencode-ai CLI globally via npm
RUN npm i -g opencode-ai

# Use bunx to run the oh-my-opencode installer with specific flags
# This configures the environment and enables opencode-zen while disabling other providers
RUN /root/.bun/bin/bunx oh-my-opencode install --no-tui --claude=no --gemini=no --copilot=no --opencode-zen=yes

# Create the authentication configuration file for OpenRouter
# Note: The API key here is a placeholder and should be replaced or managed via environment variables
RUN echo "{\"openrouter\": {\"type\": \"api\",\"key\": \"sk-or-v1-...\"}}" > ~/.local/share/opencode/auth.json

# Verify the installation by checking the version of opencode
RUN opencode --version

# You may need to run the install before starting opencode
# RUN CI=true pnpm install

# The entrypoint defines the command that will run when the container starts
# In this case, it executes the 'opencode' binary
# You may need a "opencode.json" and a ".opencode/oh-my-opencode.jsonc" to control settings
ENTRYPOINT ["opencode"]
