Docker for Mac is in transition to being a subscription product for companies.
containerd can do the same things as Docker for Mac… but the UI isn’t quite as nice.
Here are the steps to use it (at least on Intel based Big Sur MacOS):
brew install lima
# add an alias for the new docker command
echo 'alias docker="lima nerdctl"' >> ~/.bash_profile
source ~/.bash_profile
# start the background service
limactl start
docker ps
This doesn’t uninstall Docker for Mac, but does get you a new command that works well. Colima has a helper for running k8s. (Untested)
brew install kubectl colima
colima start --with-kubernetes
kubectl config get-contexts
kubectl config use-context <context_name>
kubectl get node
