Dev Container Features

A collection of dev container features for improving development workflow.

agent-persistence

Install all four persistence Features (Claude Code, Codex, Gemini and GitHub CLI), each with its own Docker volumes. This Feature has no options and uses the default user scope. To select tools or use workspace scope, add the individual Features below.

Usage: Add to VS Code User Settings (settings.json):

{
  "dev.containers.defaultFeatures": {
    "ghcr.io/fjktkm/devcontainer-features/agent-persistence:2": {}
  }
}

Selected tools

Add only the Features you need, for example:

"features": {
    "ghcr.io/fjktkm/devcontainer-features/codex-persistence:1": {},
    "ghcr.io/fjktkm/devcontainer-features/github-cli-persistence:1": {}
}

Feature	Persisted directories
codex-persistence	~/.codex
claude-persistence	~/.claude
gemini-persistence	~/.gemini, ~/.cache/google-vscode-extension, ~/.cache/cloud-code
github-cli-persistence	~/.config/gh

Individual tool Features support scope:

• user (default): share configuration between containers on the same Docker host.
• workspace: separate configuration by devcontainerId.

For example:

"features": {
    "ghcr.io/fjktkm/devcontainer-features/codex-persistence:1": {
        "scope": "workspace"
    }
}
