opencode-cloud

[!WARNING] This tool is still a work in progress and is rapidly evolving. Expect frequent updates and breaking changes. Follow updates at https://github.com/pRizz/opencode-cloud (mirror: https://gitea.com/pRizz/opencode-cloud). Stability will be announced at some point. Use with caution.

A production-ready toolkit for deploying and managing opencode as a persistent cloud service, sandboxed inside a Docker container for isolation and security.

This project uses the opencode fork at https://github.com/pRizz/opencode, which adds additional authentication and security features.

Quick install (cargo)

cargo install opencode-cloud
opencode-cloud --version

Quick install (npm)

npx opencode-cloud@latest --version

bunx opencode-cloud@latest --version

Or install globally:

npm install -g opencode-cloud
opencode-cloud --version

Deploy to AWS

Quick deploy provisions a private EC2 instance behind a public ALB with HTTPS. A domain name is required for ACM certificate validation. A Route53 hosted zone ID is required for automated DNS validation.

Features

• Sandboxed execution - opencode runs inside a Docker container, isolated from your host system
• Persistent environment - Your projects, settings, and shell history persist across restarts
• Cross-platform CLI (opencode-cloud / occ) - Works on Linux and macOS
• Service lifecycle commands - start, stop, restart, status, logs
• Platform service integration - systemd (Linux) / launchd (macOS) for auto-start on boot
• Remote host management - Manage opencode containers on remote servers via SSH

How it works

opencode-cloud runs opencode inside a Docker container, providing:

• Isolation - opencode and its AI-generated code run in a sandbox, separate from your host system
• Reproducibility - The container includes a full development environment (languages, tools, runtimes)
• Persistence - Docker volumes preserve your work across container restarts and updates
• Security - Network exposure is opt-in; by default, the service only binds to localhost

The CLI manages the container lifecycle, so you don't need to interact with Docker directly.

Docker Images

The sandbox container image is named opencode-cloud-sandbox (not opencode-cloud) to clearly distinguish it from the CLI tool. The preferred way to use and manage the image is via the opencode-cloud CLI (GitHub, mirror: https://gitea.com/pRizz/opencode-cloud). It handles image pulling, container setup, and upgrades for you.

Why use the CLI? It configures volumes, ports, and upgrades safely, so you don’t have to manage docker run flags or image updates yourself.

The image is published to both registries:

Registry	Image
GitHub Container Registry	ghcr.io/prizz/opencode-cloud-sandbox
Docker Hub	prizz/opencode-cloud-sandbox

Pull commands:

Docker Hub:

docker pull prizz/opencode-cloud-sandbox:latest

GitHub Container Registry:

docker pull ghcr.io/prizz/opencode-cloud-sandbox:latest

For most users: Just use the CLI - it handles image pulling/building automatically:

occ start  # Pulls or builds the image as needed

# Remove the container (keeps volumes)
occ reset container

# Remove container and volumes (data loss)
occ reset container --volumes --force

### Webapp-triggered update (command file)

When running in foreground mode (for example via `occ install`, which uses `occ start --no-daemon`),
the host listens for a command file on a bind mount. The webapp can write a simple JSON payload
to request an update.

Default paths (with default bind mounts enabled):
- Host: `~/.local/state/opencode/opencode-cloud/commands/update-command.json`
- Container: `/home/opencode/.local/state/opencode/opencode-cloud/commands/update-command.json`

Example payload:
```json
{
  "command": "update_opencode",
  "request_id": "webapp-1234",
  "branch": "dev"
}

The host writes the result to: ~/.local/state/opencode/opencode-cloud/commands/update-command.result.json

Install as a system service (starts on login/boot)

occ install

Uninstall the system service

occ uninstall

View configuration

occ config show

## Authentication

opencode-cloud uses **PAM (Pluggable Authentication Modules)** for authentication. Users created via `occ user add` authenticate to the opencode web UI.

### Creating Users

Create a user with a password:
```bash
occ user add <username>

Generate a random password:

occ user add <username> --generate

Managing Users

• List users: occ user list
• Change password: occ user passwd <username>
• Remove user: occ user remove <username>
• Enable/disable account: occ user enable <username> / occ user disable <username>

User Persistence

User accounts (including password hashes and lock status) persist across container updates and rebuilds. The CLI stores user records in a managed Docker volume mounted at /var/lib/opencode-users inside the container. No plaintext passwords are stored on the host.

Legacy Authentication Fields

The auth_username and auth_password config fields are deprecated and ignored. They are kept in the config schema for backward compatibility with existing deployments, but new users should be created via occ user add instead.

To migrate from legacy fields:

• Create a PAM user: occ user add <username>
• The legacy fields will be automatically cleared on next config save

Rebuilding the Docker Image

When developing locally or after updating opencode-cloud, you may need to rebuild the Docker image to pick up changes in the embedded Dockerfile:

# Rebuild using Docker cache (fast - only rebuilds changed layers)
occ start --cached-rebuild

# Rebuild from scratch without cache (slow - for troubleshooting)
occ start --full-rebuild

--cached-rebuild (recommended for most cases):

• Uses Docker layer cache for fast rebuilds
• Only rebuilds layers that changed (e.g., if only the CMD changed, it's nearly instant)
• Stops and removes any existing container before rebuilding

--full-rebuild (for troubleshooting):

• Ignores Docker cache and rebuilds everything from scratch
• Takes 10-15 minutes but guarantees a completely fresh image
• Use when cached rebuild doesn't fix issues

When to rebuild:

• After pulling updates to opencode-cloud → use --cached-rebuild
• When modifying the Dockerfile during development → use --cached-rebuild
• When the container fails to start due to image issues → try --cached-rebuild first, then --full-rebuild
• When you want a completely fresh environment → use --full-rebuild

Configuration

Configuration is stored at:

• Linux/macOS: ~/.config/opencode-cloud/config.json

Data (PID files, etc.) is stored at:

• Linux/macOS: ~/.local/share/opencode-cloud/

Development

# Install dependencies
pnpm install

# Configure git hooks (once after cloning)
git config core.hooksPath .githooks

# Build everything
just build

# Compile and run occ (arguments automatically get passed to the binary)
just run --version

# Run tests
just test

# Format and lint
just fmt
just lint

Note: The git hooks automatically sync README.md to npm package directories on commit.

Architecture

This is a monorepo with:

• packages/core - Rust core library
• packages/cli-rust - Rust CLI binary (recommended)
• packages/cli-node - Node.js CLI (fully supported and in parity with the Rust CLI)

Cargo.toml Sync Requirement

The packages/core/Cargo.toml file must use explicit values rather than workspace = true references.

When updating package metadata (version, edition, rust-version, etc.), keep both files in sync:

• Cargo.toml (workspace root)
• packages/core/Cargo.toml

Use scripts/set-all-versions.sh <version> to update versions across all files automatically.
