Tekton task for kind

[philiplee13]

Not an actual issue - but I feel like I'm either using this incorrectly or just missing something in general

Was taking some time to learn tekton on minikube and tried plugging and playing the task located here
Example that I used

And got the following output

+ trap cleanup EXIT
+ main
+ kind create cluster
ERROR: failed to create cluster: failed to list clusters: command "docker ps -a --filter label=io.x-k8s.kind.cluster=kind --format '{{.Names}}'" failed with error: exit status 1

Command Output: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
+ cleanup
+ kind delete cluster
Deleting cluster "kind" ...
ERROR: failed to delete cluster "kind": error listing nodes: failed to list clusters: command "docker ps -a --filter label=io.x-k8s.kind.cluster=kind --format '{{.Names}}'" failed with error: exit status 1

Command Output: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
+ true

I see the last commit was about 3 years ago, so I'm sure a lot with Docker has changed - but wanted to check first if this was expected or if I just did something wrong

Thanks!
