Portainer upgrade
If you already have Portainer installed, you’ll need to stop and remove it from your system before you upgrade the container.
To do that, run this command:
sudo docker stop portainer && sudo docker rm portainer
You will probably be prompted for your sudo password. Enter that and then the system will remove the Portainer container, but it will NOT delete your Portainer data as we didn’t remove that.
Next, you’ll want to pull the latest Portainer image:
sudo docker pull portainer/portainer-ce:latest
Once that is done, you’re ready to deploy the newest version of Portainer:
sudo docker run -d -p 9000:9000 -p 8000:8000 --name portainer --restart always -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data portainer/portainer-ce:latest
Now you can go to http://your-server-address:9000 and login.
Note:
Doing this will NOT remove your other applications/containers/etc.
