¿Cómo añadir a Docker en el grupo sudo en nuestro VPS Ubuntu 20.04 LTS?

Ejecutamos:

sudo -i

Esto hará que accedamos a root.

Ejecutamos:

sudo groupadd docker

Si ya existe, la consola nos lo dirá:

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
groupadd: group 'docker' already exists
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

Ejecutamos:

sudo usermod -aG docker $USER

Si es correcto, la consola no devolverá nada.

Ejecutamos:

docker run hello-world

Si la consola responde correctamente, sin "sudo" es que has incorporado tu usuario con docker y sudo.

Si ya existe, la consola nos lo dirá:

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Hello from Docker!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
    (amd64)
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash
