I am trying to install cvat, so I am following the Installation guide

The first step run smoothly, however when I try to create a superuser with the command

docker exec -it cvat_server bash -ic 'python3 ~/manage.py createsuperuser'

After a few minutes, I get the following error:

Traceback (most recent call last):
  File "/opt/venv/lib/python3.8/site-packages/django/db/backends/base/base.py", line 219, in ensure_connection

    Is the server running on host "cvat_db" (172.18.0.3) and accepting
    TCP/IP connections on port 5432?


The above exception was the direct cause of the following exception:

What should I do to fix this and use CVAT?

My Ubuntu version: Ubuntu 22.04.1 LTS

I thought adding Django's authentication system might solve it so I did pip install django-auth but it changed nothing

I have had the same problem but I found a solution. Some user suggested a problem with docker installation here. My way to solve it is:

  • Remove docker installation completely. This can help.
  • Install docker from the atp repository:

sudo apt install containerd

sudo apt install docker.io

Do everything as in the CVAT installation guide, but ignore the part about installing Docker and use the commands above. With this solution some comands indicated in the installation guide will require sudo. In the guide:

Instead of docker compose up -d use sudo docker-compose up -d

Run with sudo docker-compose up
