Fix Cannot connect to the Docker daemon at unix:///var/run/docker.sock.
Raw
fix-docker-daemon-connection.md

To fix the "cannot connect to the Docker daemon at unix:///var/run/docker.sock" error on macOS, try exporting the following:

export DOCKER_HOST=unix://$HOME/.docker/run/docker.sock

Alternatively, you can use Docker over TCP. Here's how to configure Docker Desktop to expose the Docker daemon via TCP instead of a Unix socket:

  1. Open Docker Desktop.
  2. Navigate to Settings > General.
  3. Enable "Expose daemon on tcp://localhost:2375 without TLS" (Note: This option exposes the Docker daemon without security, so use it cautiously).
  4. Save the settings and restart Docker Desktop.

After completing these steps, you can export DOCKER_HOST as follows:

export DOCKER_HOST=tcp://localhost:2375
