The biggest difference is that Podman and Buildah are funded by and used underneath OpenShift which is a huge money maker for Red Hat while Docker is on life support with Mirantis holding the plug.

Momentum around Docker that isn't Desktop all but halted in 2018 or so.

This is a common misconception. While podman is indeed installed on Red Hat CoreOS it does not run the containers used by OpenShift. OCP 4 uses CRI-O to run all containers and if you login as the core or root user and run podman ps you wil not see any running containers.

Oh wow, I thought OCP used crun at least. Surprising!

I do think the revenue from OpenShift and friends funds Podman/buildah/crun/etc.

Podman and CRI-O share the low level libraries (namely containers/image and containers/storage).

crun is Tech Preview in OpenShift 4.12: https://cloud.redhat.com/blog/whats-new-in-red-hat-openshift...

Right. But Docker is not a charity. I think that Podman/Buildah is actually a superior solution. This might unfortunately mean the ultimate demise of Docker, Inc. as we know them.

To be fair, I literally use Docker everyday. So I'm not necessarily rooting for its demise. But I'm seemingly happy that innovation is at least coming from somewhere in this space.

Mirantis acquired the Docker Enterprise business. When Docker focused on Desktop, they became a $50MM/year company.

You mean "when Docker decided to strong-arm their wealthiest customers into paying tens of thousands per month with a few months of warning, they became a $50MM/year company?"

Interested in seeing how sticky that revenue is. A big chunk of its value is provided by other free solutions.

Really? I thought Docker was pretty widely used at companies for deployment, etc. At least it was at my company ~1 year ago. I wasn't aware that Docker was on life support in any sense.

Widely used, but I don’t think it makes a whole lot of money to sustain itself

I think it’s north of $100m a year now so all of the life support talk is not based in truth.

Around $135m / year according to this: https://sacra.com/p/docker-plg-pivot/

A lot of people use Docker

A lot of people also don't pay for Docker
