You can also run podman with this setup, which is ideal for trying it out. Minikube is running through Docker Desktop. Ideally, we would only want to stick to Minikube and Scaffold. Make docker images easily available to kubernetes clusters.

So to use an image without uploading it, you can follow these steps: Set the environment variables with eval $ (minikube docker-env) Build the image with the Docker daemon of Minikube (eg docker build -t my-image .) K9S snapshot of freshly installed Minikube cluster Need Docker Compose? Docker is for Linux systems. The "docker" driver should not be used with root privileges. Then we need to configure docker-cli to use Minikube VM. Do not use in production. This is done by exposing a port on which the service is running. minikube start --container-runtime=docker --vm=true 3 Point Docker CLI to minikube You can refer to the full docs here..

All components (Metastore, HiveServer2, MR3 DAGAppMaster) will be running inside Minikube. ; Line 4: the --no-kubernetes flag allows to use minikube only as a Docker Desktop replacement without starting Kubernetes itself. Use it to verify the installation: kubectl version As more support keeps coming for the new chips, this will be easier to do in the near future. You can visit the Repo on Gtilab to learn more but here is the tldr;, a command to run on the remote server : docker run -d -it --network minikube --name minikube-proxy \ --restart unless-stopped -p 18443:18443 chevdor/nginx-minikube-proxy.

This means you don't need to manually remember to perform the command each time you want to use Docker in a new shell. Set the image in the pod spec like the build tag (eg my-image) Select Minikube and press "OK," as shown in the image below: If you use VS Code, it is even simpler. This page shows how to use Helm and a pre-built Docker image available at DockerHub in order to operate Hive on MR3 on Minikube.
