Installs opencode from official GitHub release assets and persists shared state across devcontainers.

"features": {
    "ghcr.io/sliekens/devcontainer-features/opencode:1": {}
}

Pin a specific version when you need deterministic builds:

"features": {
    "ghcr.io/sliekens/devcontainer-features/opencode:1": {
        "version": "1.3.13"
    }
}

opencode uses XDG base directories for data and configuration:

These directories are bind-mounted from the host so that auth credentials and settings are preserved across container rebuilds.

Because Docker cannot bind-mount a directory that does not yet exist, consuming devcontainer.json files should add an initializeCommand to pre-create these directories on the host before the container starts:

{
    "image": "mcr.microsoft.com/devcontainers/base:ubuntu",
    "features": {
        "ghcr.io/sliekens/devcontainer-features/opencode:1": {}
    },
    "initializeCommand": "mkdir -p \"$HOME/.local/share/opencode\" \"$HOME/.config/opencode\""
}
