Persists Claude Code configuration across container rebuilds using Docker named volumes.
| Option | Type | Default | Description |
|---|---|---|---|

Use alongside a Claude Code installation feature (e.g., ghcr.io/anthropics/devcontainer-features/claude-code).
Add features to your devcontainer.json:
{
"features": {
"ghcr.io/esimkowitz/devcontainer-features/fish-starship:1": {},
"ghcr.io/esimkowitz/devcontainer-features/ssh-signing:1": {},
"ghcr.io/esimkowitz/devcontainer-features/direnv:1": {},
"ghcr.io/esimkowitz/devcontainer-features/claude-code-persistence:1": {}
}
}VS Code automatically forwards your SSH agent into dev containers. The ssh-signing feature detects this at shell login and configures git commit signing automatically — no additional configuration needed.
