Test Docker by grabbing Hello world image

docker run hello-world

Result:

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. (Assuming it was not already locally available.)

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

Add myuser to the docker group

sudo usedmod -aG docker myuser

next logout and back in and you can run docker command with out sudo

logout

Testing with out sudo – ps comamnd lists containers running

docker ps

Next install Nice GUI for Docker : Portainer

docker volume create portainer_data

Next install Portainer as the volume has been created.

docker run -d -p 8000:8000 -p 9443:9443 --name portainer --restart=always -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data portainer/portainer-ce:2.21.5
