podman

Overview

The podman driver is an alternative container runtime to the Docker driver.

Requirements

• Install podman

Experimental

This is an experimental driver. Please use it only for experimental reasons until it has reached maturity. For a more reliable minikube experience, use a non-experimental driver, like Docker.

Usage

It’s recommended to run minikube with the podman driver and CRI-O container runtime (except when using Rootless Podman):

minikube start --driver=podman --container-runtime=cri-o

Alternatively, start minikube with the podman driver only:

minikube start --driver=podman 

To make podman the default driver:

minikube config set driver podman

Rootless Podman

By default, minikube executes Podman with sudo. To use Podman without sudo (i.e., Rootless Podman), set the rootless property to true:

minikube config set rootless true

For Rootless Podman, it is recommended to set --container-runtime to containerd:

minikube start --driver=podman --container-runtime=containerd

See the Rootless Docker section for the requirements and the restrictions.

Known Issues

• On Linux, Podman requires passwordless running of sudo. If you run into an error about sudo, do the following:

$ sudo visudo

Then append the following to the section at the very bottom of the file where username is your user account.

username ALL=(ALL) NOPASSWD: /usr/bin/podman

Be sure this text is after #includedir /etc/sudoers.d. To confirm it worked, try:

sudo -k -n podman version

• On all other operating systems, make sure to create and start the virtual machine that is needed for Podman.

podman machine init --cpus 2 --memory 2048 --disk-size 20
podman machine start
podman system connection default podman-machine-default-root
podman info

Troubleshooting

• Run minikube start --alsologtostderr -v=7 to debug errors and crashes
