Portainer is my favorite docker management tool, actually only one I used. If you have better one, please let me know. This post is to summarize some usage during playing with application.

Install Docker and Portainer
/data folder on Linux (C:\\data on Windows).You’ll need to persist Portainer data to keep your changes after restart/upgrade of the Portainer container. Docker Deploy document: https://portainer.readthedocs.io/en/latest/deployment.html . You can use a bind mount on Linux to persist the data on the Docker host folder:
#Ubuntu 20.04
sudo apt install docker.io
sudo apt install docker-compose
#CentOS 7, Debian, Ubuntu 18.04/16.04
curl -sSL https://get.docker.com/ | sh
systemctl start docker
systemctl enable docker
root@Ubuntu18:/# docker volume create portainer_data
root@Ubuntu18:/# docker run -d -p 9000:9000 --name portainer --restart always -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data portainer/portainer-ce:latest
root@Ubuntu18:/# which docker
root@Ubuntu18:/# find . -type d -name "portainer_data"
./var/lib/docker/volumes/portainer_data
or in CentOS:
[root@centos-nextcloud-aria2 ~]# find / -type d -name “portainer_data”
/var/lib/docker/volumes/portainer_data
You can try out the public demo instance: http://demo.portainer.io/ (login with the username admin and the password tryportainer).
Update Portainer
1. Update image
root@Ubuntu18:/# docker stop portainer
portainer
root@Ubuntu18:/# docker rm portainer
If you only do start portainer, it won’t use the latest image to start. You will have to remove old version container, then create a new portainer with downloaded new image.
root@Ubuntu18:/# docker start portainer
portainer
some os, you might need to use command “docker pull docker.io/portainer/portainer-ce”
If you could not find image, just use command “docker search portainer-ce”
[root@centos7-docker-portainer ~]# docker search portainer-ce

2. Start Container with new image
[root@centos7-docker-portainer ~]# docker run -d -p 9000:9000 --name=portainer --restart=always -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data portainer/portainer-ce
