Docker Daemon not running

[pangsark]

Hi,

When I ran docker-compose up -d --build to bring up the docker container for the pagila-hw, I got a long error message and failed.

Then I ran docker ps to verify that nothing was brought up, I got: Cannot connect to the Docker daemon at unix:///run/user/1351/docker.sock. Is the docker daemon running?

I also verified that my docker was installed and was the right version and I was wondering if there is anything I can do to connect to the daemon.

Since you didn't post the error message, there's nothing I can do to help. In general, whenever something's not working and you're asking for help, you should always copy/paste your full terminal session.

Hi Mike,

I'm sorry about that, here is the full error message after running docker-compose up -d --build:

The last line of your error message contains

FileNotFoundError(2, 'No such file or directory')

This tells us that docker is trying to start but is missing some necessary file(s) to do so. Probably you are missing the files from the git submodule. You can verify this by running ls pagila and checking that the contents of this folder are empty. Step 1 in the instructions detail how to populate this folder, and my guess is that redoing this step will fix your problem.

This worked well, thank you!
