From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Should I bother learning Podman? (lemmy.goblackcat.com)

I am already fairly comfortable using docker and its tool set. Is the tide shifting towards Podman? Should I start learning how to use Podman? Thanks in advance.

I want full control over which containers launch when. I also typically have a different requirement in which network a container runs and I want to re-use existing databases instead of spinning up a new one for each service. I want specific container names. And so on.

In short: I want full control and customization.

You can tell which service depends on which in compose, you can create, specify and set networks and add containers to them, you can keep a central database and just add the network of it to your new services, and you can also specify a container name.

As I see it (and for my compose usage), everything you mentioned works in compose.

Besides, what is your alternative? Do you just use the docker cli? I personally found that to be way less flexible than compose.

The point is, if I get a compose file, all of that is already wired up with expectations of the maintainer. When I start heavily modifying it, I end up with an unmaintainable mess. So I rather look into what the service(s) actually require and build it for my use case.

Besides, what is your alternative?

The CLI, yes. And for my own server Ansible. But the semantics of the ansible module are identical to the CLI. Knowing the CLI by heart gets me much further than knowing docker-compose by heart. (Actually, I would have to look into the manual for docker-compose all the time, while I can simply do podman --help to see what parameters it needs, if I forgot something.)
