containerd doesn’t support pull-through-cache

This means that microk8s(which is awesome!) doesn’t support fetching data through pull-through-caches. I’ve read that later versions of containerd does support it but that’s not what microk8s is running in that case. Oh well, now I’ve set my private registry to not be a pull-through-cache because it can’t be that and an ordinary private registry. So now I pull images, tag them with my local registry as the source and push them there:

cjp@amd:~$ docker tag nginx cacher.svealiden.se:5000/nginx:20210925
cjp@amd:~$ docker push cacher.svealiden.se:5000/nginx:20210925
The push refers to repository [cacher.svealiden.se:5000/nginx]

Then microk8s can pull them. Maybe this would have gone more quickly without that drink three hours ago?
