Running docker inside Kubernetes with containerd

Since K8S v1.11 Runtime was changed from dockerd to containerd.
I'm using Jenkins over kubernetes to build docker images using Docker outside of Docker (dood).



When I tried to switch to use the socket file from conatinerd (containerd/containerd.sock was mapped ad /var/run/docker.sock) with the regular docker client a got the following error Get http://%2Fvar%2Frun%2Fdocker.sock/v1.39/containers/json: net/http: HTTP/1.x transport connection broken: malformed HTTP response "x00x00x00x04x00x00x00x00x00".



Can docker client be used with containerd?

          Disclaimer: as of this writing containerd didn't replace Docker, you can install containerd separately from Docker, and you can point the Kubernetes CRI to directly talk to the containerd socket.



          So, when you install Docker it does install together with containerd and the Docker daemon talks to it. You'll see a process like this:



          docker-containerd --config /var/run/docker/containerd/containerd.toml


          However, the Docker client still talks to the Docker daemon, that's why when you run the Docker client in your container you still need to talk directly to the Docker daemon (/var/run/docker.sock), so you can switch back to /var/run/docker.sock and I believe it should work.

          What visual should I use to simply compare current year value vs last year in Power BI desktop

          Image
          0 I have column SubToBind that shows current year ratio and column PY SubToBind which shows previous year ratio. How can I simply create a card that would be displaying them both in a nice way? Something like that: I cannot achieve that with regular card, I also tried Card with States by OKViz but also unable to see both values. In KPI visual - I dont like the word "Goal", it will confuse end users. Are there any cards or other visuals that would do the job?
