How to Update Portainer to the Newest Version
In this blog post we’ll look at a couple of ways to update Portainer on your system. First we’ll look at how to update Portainer using OpenMediaVault. Then we’ll look at how to update Portainer on a standard Docker setup.
If you have OpenMediaVault installed, the process is super simple. Just login to OMV and go to OMV-Extras, then click the Docker tab. On that page, you can click the Portainer dropdown and then just click install. This will update your Portainer container even if you already have Portainer installed.
Standard Docker Setup
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:
docker pull portainer/portainer-ce:latest
Once that is done, you’re ready to deploy the newest version of Portainer:
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.
