Docker - moby - 404 = confusion

Ask Fedora
1

Greetings, I have installed Fedora Server 32 with Cockpit and looking forward to a wonderful experience using it as a host for several docker based applications.

However I cant install Docker. I get some references to Moby which seems old, the Docker project instructions for Fedora do not work.

sudo dnf install docker

Got that, only hope Moby will follow the Docker releasesā€¦ Akihiro say its only removed the brand name, but I really donā€™t get why, Docker is freeā€¦

I suggest all of you to use Podman instead (https://podman.io)

Iā€™ve been quite happy using Podman and Buildah, but Iā€™ve not been able to use them exclusively. For example:

I donā€™t see the point. Well, yes, a graphical interface to handle your docker images, but surely the Docker guys has that somewhere? I tried Podman for like 30 minutes and it was just adding to the confusion.

I went with Fedora Server > Docker > Apps for a reason, and that is to reduce the number of layers.

You can go:
Host > VM > Docker > Webapps but with this solution I have Host > Docker > Webapps

Now, I realize Podman isnā€™t a layer as such, but getting used to Docker and finding a solution made by Docker for Docker seems a more reasonable approach. If they have one, which I donā€™t know at this time.

ehm, scrap that, seems only https://www.portainer.io/ is up to date and active of those listed in the article.

Well, Cockpit can let you manager your Podman containers using a web interface just like Portainer does with Docker ones. You just must install the ā€œpodman-containerā€ package (itā€™s like a ā€œpluginā€ for Podman) and thatā€™s all.
