Kompose is a tool that converts docker-compose.yml into Kubernetes YAML config files.
You can easily install it globally on most Linux distributions using this command:
sudo curl -L https://github.com/kubernetes/kompose/releases/download/v1.22.0/kompose-linux-amd64 -o /usr/local/bin/kompose chmod a+x /usr/local/bin/kompose
After that, run
kompose convert
in a directory containing a docker-compose.yml. See the Kompose website for further information.
