Portainer.io - A new version is available 2.0.0

[paolos7709]

Hello team,
I just installed IOTstack and when logged in into Portainer console, I see it's saying that new version is available.
I see that new version 2.0.0 is available... I also see that new container is called "portainer/portainer-ce" and not "portainer/portainer" anymore. Will be IOTstack containers updated as well...?

Last but not least, good work you've done so far. Very useful project!

The short answer is "when the maintainer of the Portainer image builds a new image based on the updated version of Portainer, and uploads that to Dockerhub." I hope that makes sense.

What you need to do from time to time is:

$ docker-compose -f ~/IOTstack/docker-compose.yml pull

and, after that finishes, see what's changed by running:

$ docker images

In my case, the answer was:

portainer/portainer      latest              dbf28ba50432        2 months ago        62.5MB

Focus on these two lines:

postgres                 latest              405fbb2810d7        30 hours ago        265MB
postgres                 <none>              d3508eac6d79        8 days ago          265MB

The first one has just been pulled down from Dockerhub. The second one (with the "<none>" tag) used to be the "latest" but you can't have two images tagged "latest" so the old one has had its tag removed.

That pattern (one tagged "latest" the other tagged "<none>") tells me a couple of things:

• postgres has been updated
• portainer hasn't been updated yet

But, that old image of postgres is the one that is still running. I switch to the new image by "upping" the stack:

$ docker-compose -f ~/IOTstack/docker-compose.yml up -d
gitea is up-to-date
Recreating postgres ... 
influxdb is up-to-date
pihole is up-to-date
grafana is up-to-date
nodered is up-to-date
mosquitto is up-to-date
portainer is up-to-date
Recreating postgres ... done

Now we can get rid of the old image. There are several ways but the one I use is:

$ docker system prune

  - all networks not used by at least one container
  - all dangling images
  - all dangling build cache

Most images/containers work like that. Node-Red is an exception where you have to remove its base image:

$ docker rmi "nodered/node-red"
$ docker-compose -f ~/IOTstack/docker-compose.yml pull
$ docker-compose -f ~/IOTstack/docker-compose.yml up --build -d

The --build applies to anything that has a Dockerfile in its services directory. You can find out what those are like this:

$ find ~/IOTstack/services -name "Dockerfile"
/home/pi/IOTstack/services/nodered/Dockerfile

Figuring out when Node-Red has been updated is a bit of a challenge. I wrote a script called "nodered_version_check" which you are welcome to use:

#!/bin/sh

LATEST=$(wget -O - -q https://raw.githubusercontent.com/node-red/node-red-docker/master/package.json | jq -r .version)
INSTALLED=$(docker inspect iotstack_nodered:latest | jq -r .[0].ContainerConfig.Labels[\"org.label-schema.version\"])

if [ "$INSTALLED" = "$LATEST" ]; then 

   echo "Node-Red is up-to-date (version $INSTALLED)"

else

/bin/cat <<-COLLECT_TEXT

	====================================================================
	Node-Red can be updated:

	    Local Version: $INSTALLED
	   Remote Version: $LATEST

	Proceed like this:

	   $ cd ~/IOTstack
	   $ docker rmi "nodered/node-red"
	   $ docker-compose pull
	   $ docker-compose up --build -d

	Step 2 removes the old "base" image for Node-Red.

	Step 3 pulls any updates to other containers (and can be omitted)

	In step 4, the "--build" option causes the Dockerfile for Node-Red
	to run. That pulls down the update, builds a new local image while
	the old version is still running, then swaps new for old.

That script depends on wget and jq so, if it doesn't work out-of-the-box:

$ sudo apt update
$ sudo apt install -y jq wget

I hope my earlier reply helped.

Please see * * THIS PROJECT IS DORMANT * *.

It is possible that your problem has been fixed on SensorsIot/IOTstack. In any case, you are more likely to get support if you migrate your installation to SensorsIot/IOTstack, find that your problem has not been fixed, and open another issue there.

If you have not already joined the Discord channel, you can often get help there too.

I'd really appreciate it if you would close this issue on gcgarner/IOTstack:

• Recently opened issues give the impression that this repo is active - it isn't.
• A pile of ancient open issues with no responses give the impression that the IOTstack project has been abandoned - it hasn't been.

Forking the repo was the only possible way of continuing once Graham Garner "disappeared".

Hello @Paraphraser.
Thanks a lot for your reply. I learned a lot from it.
You didn't helped me directly, but your answer helped me to understand some basics. So thanks a lot!
I wanted to upgrade Portainer to version 2.0.0. The problem was, that Portainer container name has been changed from "portainer/portainer" to "portainer/portainer-ce". So All I've done at the end was just changing the container name in docker compose file and then all worked well...

$ cat docker-compose.yml portainer: container_name: portainer image: portainer/portainer-ce restart: unless-stopped ports: - 9000:9000 volumes: - /var/run/docker.sock:/var/run/docker.sock - ./volumes/portainer/data:/data

Thanks once more for your reply and have a great day! P.
