Question

How do I fix the Docker error "mounts denied: The path /tmp/... is not shared from the host"?

Answer

Add the path to Docker File Sharing (Recommended)

You need to explicitly tell Docker Desktop that it is allowed to access your host's /tmp directory.

1. Open Docker Desktop.
2. Click the Gear icon (Settings) in the top right corner.
3. Navigate to Resources > File Sharing.
4. Click the + (Add) button.
5. Enter /tmp (or the specific path like /tmp/kestra-wd) and press Enter.
6. Click Apply & restart.

Once the changes are applied, go to the terminal and rerun the docker compose command (docker compose up -d) to stand up Kestra
