I am looking for a mircok8s guide on how to do the upgrade from Docker to Containerd. Any suggestions?
From v1.14 MicroK8s has moved to containerd. May i know what MicroK8s version you are using?
I have the most updated version, but I installed docker not knowing about containerd. Is it just a simple uninstalling docker and installing containerd?
EDIT: Looks like its just a simple
sudo apt-get purge docker-ce sudo apt-get upgrade sudo apt-get autoremove sudo apt install -y containerd.io sudo reboot
I like how microk8’s just works
You don’t have to install
MicroK8s includes containerd already.
It also doesn’t clash with docker too. In my case, i use docker to help me build my images.
It was not installed when I first installed microk8’s. I had to install docker / containerd.io my self. This was on a PI. No idea if that makes a differents
Yes it should be installed. How did you check that it is not installed?
unfortunately this was a few weeks so I do not have the error. I believe it had to do with unable to start my container. I made no yaml, or code changes. I installed docker and it worked like a charm.
I think it is just loading up. I don’t think installing docker fixed it. May i know the MicroK8s channel you are using?
Here is the command I used to install
sudo snap install microk8s --classic --channel=1.19
I waited about 30 mins for the container to start. Did a few deployments with the same result. Installed docker and the issue was fixed. If the issue wasn’t microk8’s / containerd it may have been a corrupted library or something. I’ve had Pi’s corrupt packages before, so it would be no surprise
