 Unfortunately `devcontainer.json` is not yet supported with VScode Remote-SSH plugin. You can track recent development [here](https://github.com/microsoft/vscode-remote-release/issues/2994).
 The easiest way to use avd-all-in-one container with remote SSH is creating a simple alias: `alias avd="sudo docker run --rm -it -v $(pwd):/home/avd/projects/ avdteam/avd-all-in-one"`

+### run avd-all-in-one in k8s
+
+[k8s-avd-cvp.yml](k8s-avd-cvp.yml) is an example pod definition for running avd-all-in-one on CloudVision (CentOS), however
+it should work on other linux distributions (the CVP env vars won't be needed in that case).
+
+1. Download the docker image: `docker pull avdteam/avd-all-in-one`
+2. Create avd group and user: `groupadd -g 1000 avd && useradd avd -u 1000 -g 1000`
+3. Create projects in `/home/avd`
+4. Deploy the k8s pod: `kubectl apply -f /cvpi/conf/kubernetes/k8s-avd-cvp.yml`
