This means the portainer is reading /var/run/docker.sock locally. Also we can add the existing enviroments, look at the end.

Container Status

From the screen, you will be able to see the important information such as container ip, exposure port and the image. It likes docker inspect <container>

Create Container

You can deploy a container with the page. But I like to do it in cli.

Manage Volumes

You can see all the volumes here. In cli is docker volume ls
if some volumes unused it will show the unused tag and you can remove that easily. You can click that show the information.

Manage Networks

You will see all the networks here, if you are using docker-compose that will create automatically. Otherwise, you need to docker network create <network> first. And you can click inside to inspect which container is using this network. In cli docker network inspect <network>

View Logs

You can click the paper icon to view that container logs. In cli docker logs <container>

On side menu, click the setting > Environments You can add the existing enviroments here. And portainer is able to support K8s. Very cool. Alternatively, you can use lens as well.

Following the instruction, run the portainer agent on your existing host then input the information of your enviroments. Click connect is done.
