Portainer and Docker 26.1 ?

[spagu]

Ask a Question!

Quick one? Does the portainer support Docker 26.1? https://docs.docker.com/engine/release-notes/26.1/

I upgraded by accident, and it is NOT working for me. I am getting this error from Portainer:

WRN github.com/portainer/portainer@v0.6.1-0.20240312222218-6e11c10bab52/api/platform/platform.go:70 > failed to retrieve docker info | error="Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?"

The agents seem happy though...

Update to this, re-deploying the entire stack seems to have fixed the issue...

Normally just running:

docker service update portainer_agent --force
docker service update portainer_portainer --force

Resolves my issue, but I had to completely remove portainer, it's network and redeploy it.

So.... Yes? it's working?

We have a blog post about this: https://www.portainer.io/blog/portainer-and-docker-26

Essentially if you need to support Docker 26, we recommend updating to the 2.20 branch. This branch is a STS (Short-Term Support) branch, so make sure you understand what that means before updating (and take a backup first!). For production environments, we recommend staying with Docker 25 or below and the Portainer 2.19 branch.
