Problem with docker-compose under WSL2/Ubuntu20.4

[mirekh68]

Just at the beginning of the course, (environ setup : lesson https://academy.jfrog.com/path/conan/conan-essentials/590849 )after issuing the command:

~/projects/training/docker_environment$ docker-compose up -d

I've got an error message:

ERROR: Couldn't connect to Docker daemon at http+docker://localhost - is it running?

If it's at a non-standard location, specify the URL with the DOCKER_HOST environment variable.

I am using Ubuntu 20.04 on WSL 2

@mirekh68 Were you able to solve this ?
I am getting the same error.

I had the same issues, and did a bunch of things that solved it. Not sure which one worked exactly and you probably can solve it another way. I assume that docker service is just turned off sudo service --status-all, maybe sudo service docker start would suffice, but I took the long road.

What I did:
0. sudo systemctl status didnt work on ubuntu

1. Install Windows Subsystem For Linux from Microsoft Store
2. Launch Ubuntu and sudo -e /etc/wsl.conf
3. Add

[boot]
systemd=true

4. Save.
5. In powershell wsl --shutdown
6. Start ubuntu
7. sudo systemctl status should work now
8. sudo systemctl start docker

If you are on mac, use this command:
brew install --cask docker
Then run GUI of docker.
