I'm using a Chromebook Pixel 2, and it's easier to get Rocket working than Docker. I recently installed Rocket 1.1 into /usr/local/bin, and have a clone of the Kubernetes GitHub repo.
When I try to use ./hack/local-up-cluster.sh to start a cluster, it eventually fails with this message:
Failed to successfully run 'docker ps', please verify that docker is installed and $DOCKER_HOST is set correctly.According to the docs, k8s supports Rocket. Can someone please guide me about how to start a local cluster without a working Docker installation?
Thanks in advance.
Try running export CONTAINER_RUNTIME="rocket" and then re-running the script.
You need to set three environment variables before running ./hack/local-up-cluster.h:
$ export CONTAINER_RUNTIME=rkt
$ export RKT_PATH=$PATH_TO_RKT_BINARY
$ export RKT_STAGE1_IMAGE=PATH=$PATH_TO_STAGE1_IMAGEThis is described in the docs for getting started with a local rkt cluster.
