| I wrote a comment for the general comment section, but wanted to respond to your comment as it contains valid criticism. 1. Mirantis did not acquire Docker Inc., they only bought Docker Enterprise... >> You are right. That's a mistake. 2. k8s did'nt remove dockershim for political reason.. >> That is a valid point and the official story. Imho I think the acquisition was nevertheless something that played an accelerating role in this, since it happened relatively soon after the acquisition. Mirantis acquired Docker Enterprise in November 2019, and the end of Dockershim support was announced in 2020. I've heard that from a few other people as well. BUT this is just rumor, so you might be right. 3. Rate limits have nothing to do with the container runtime.. >> This is 100% true. Nevertheless, dockerhub is part of Docker and therefore a rate limit on the official Docker registry is something that has made our customers switch registry to other registry providers or implement their own container registry. Therefore, they are getting rid of this service, which is part of the Docker-only ecosystem, so its usage in enterprises is decreasing. 4. RedHat support switched to Podman as it is on of their products.. >> It only makes sense for RedHat to support Podman since it's from their own product forge. You are right about that. That said, there are a lot of companies using RH and paying for it, which automatically leads to a decrease in Docker usage vs Podman. Less use of Docker means more use of Podman.
Last but not least, RedHat would not invent Podman if there was no need for an independent tool to Docker. Podman helps in some areas where Docker lacks features, such as support for pods, rootless mode, etc. Thanks for your criticism! It is appreciated and helps us to do better. |
