Portainer has been, for a while, my go-to container administration platform. It’s not solely very highly effective, however it’s additionally fairly user-friendly, and within the recreation of containers, that’s a powerful mixture.

Portainer is deployed as a container itself. And with the event crew often releasing new variations, you all the time need to ensure you keep on high of that. To that finish, any time you log into your Portainer occasion and see {that a} new model is obtainable (Determine A), it’s time to improve as quickly as attainable.

My present Portainer deployment is old-fashioned.

As a result of Portainer is a container, you’ll be able to’t simply replace the present deployment; as a substitute, you must cease and take away your present deployment and redeploy. Thankfully, you’ll be able to deploy Portainer with persistent storage (as I present in Find out how to deploy the Portainer container administration software with persistent storage), which implies if you redeploy your entire configurations and containers will stay intact.

With that mentioned, let’s replace Portainer to the newest model.

What you’ll want

To observe alongside, you’ll want a machine operating Docker or Docker Neighborhood Version. In case you don’t have already got a Portainer occasion already up, you’ll be able to nonetheless deploy the newest launch, simply skip the primary steps of stopping and eradicating the older occasion. You’ll additionally want a consumer who belongs to the docker group in your internet hosting server.

Let’s get to the replace.

Find out how to cease and take away the present Portainer container

The very first thing you should do is situated the Portainer container ID with the command:

docker ps -a | portainer

You must see one thing like this within the output:

0eab77c40087   portainer/portainer-ce      "/portainer"         4 weeks in the past  Up 3 weeks      >8000/tcp, :::8000->8000/tcp,>9443/tcp, :::9443->9443/tcp, 9000/tcp         portainer

The random string of characters is the container ID (within the above case it’s 0eab77c40087). To cease and take away the container, you solely want to make use of the primary 4 characters. First, cease the container with:

docker cease 0eab

Ensure that to alter out the primary 4 characters with these of your operating Portainer container.

Subsequent, take away the container with:

docker rm 0eab

Find out how to deploy the brand new model

Earlier than we run the deploy command, let’s first pull down the newest model with:

docker pull portainer/portainer-ce:newest

As soon as the brand new picture has pulled down, deploy the newest Portainer model with:

docker run -d -p 8000:8000 -p 9443:9443 --name=portainer --restart=all the time -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/knowledge portainer/portainer-ce

Give the container time to deploy. After a minute or so, level your browser to http://SERVER:9443, the place SERVER is the IP deal with of the internet hosting server, and log again into Portainer with the identical credentials you used beforehand. You must see the brand new model has been deployed (Determine B).

Determine B

I went from model 2.13.1 to 2.14.1.

And that’s all there’s to updating Portainer to the newest launch. As a result of we initially deployed with persistent storage, this course of is extremely simple and painless.
