  • In this video, we will be exploring an alternative to Docker - Podman. With its claims of being faster, more secure, and compatible, it's time to see if Podman is a mature alternative to Docker. We'll also discuss its recently released Podman Desktop Application and its exciting features, as well as the possibility of switching from Docker to Podman.

    The big advantage Podman Desktop has over Docker Desktop is the licensing for enterprise use. PD is FOSS (Apache 2.0 license), where DD is only "free for small businesses (fewer than 250 employees AND less than $10 million in annual revenue), personal use, education, and non-commercial open source projects. Otherwise, it requires a paid subscription for professional use. Paid subscriptions are also required for government entities."

    I’ve started to play around with Podman just to see what it’s like. I recently discovered that you can generate a Kubernetes v1 yaml file from an existing Podman pod or container. This is good because I can run my existing docker compose files on Podman to create the containers. I then use “podman kube generate” to build a Kubernetes yaml file from my existing container setup. Maybe my method is not very practical but to me it’s still pretty cool. 🙂

      Podman-compose is dead. Podman is 100% compatible with docker-compose. Been using it for a while now. Where I work, 95% of our servers are running RHEL. And podman is running in production without any issues. Start by enabling the podman socket:
      systemctl enable --now podman.socket
      Then export the following variable to make docker-compose communicate with podman instead of docker(put the export command in .bashrc or whichever shell you're using):
      export DOCKER_HOST=unix://$XDG_RUNTIME_DIR/podman/podman.sock
      and that's it. You can use your regular compose files as usual with the docker-compose command.

    I like that podman can use quadlets, those are files under /etc/containers/systemd/ that look similar to compose. After systemctl daemon-reload, it will create a system service you can start and will auto start on the next reboot. Podman could always generate system services, but this way it regenerated with the latest systemd version and not onetime.

    Podman is backed by Red Hat, and it also is known to step away from Kubernetes standards. Rancher Desktop is light years ahead, they support containerd instead of docker to be in line with Kubernetes baseline, it based on k3s/k3d, and somehow I trust SUSE more. And yes, it can also be a drop in replacement, and not just by way of mimicking Docker but actually using Docker CE with k3d instead of containerd/k3s for these who just develop apps and don’t care about 1:1 matching environment to real Kubernetes. And it comes with Compose and other plugins, yes.

    I wonder if podman can use the HyperKit or vz or whatever it's called on MacOS 13+ and perhaps Hyper-V on Windows? I currently am using colima on MacOS M1 Max (MacOS 14) and it works like a charm.
    Also as a software engineer, I am always thrilled to try features if I need them - certainly not in a commercial project I develop for on my day-job, but certainly in private.
    I might replace docker with podman on my custom NAS at home.

      Podman supports native virtualization on Mac and Hyper-V on Windows. Will switch to default to Native Virt on Mac in Podman 5.0, currently it defaults to QEMU on Mac. 5.0 is due to be released end of February

    the biggest upside to podman desktop over docker desktop is it's currently fully opensource and free use both at home and commercially where as docker desktop is no longer free for commercial uses. Where I say currently opensourse about podman given redhats recent actions I wouldn't be surprised if they monetised podman desktop. On a server level though docker is still ahead of podman due to it's swarm mode to allow for scaleable and high available clustering if you didn't want to run a k8s cluster on prem that is (still working on my employer with that 😀).

    Podman being daemonless can make some things more annoying.
    You will have to create either cronjobs or systemd-timers to automatically start containers at boot, which Docker will do.
    Also the Docker daemon is shared between users (which is probably why it's such a pain to do Docker rootless, though Docker can also do rootless containers AFAIK), Podman doesn't have such a synchronization.
    This means, that every user will have to download or build their images anew, so if you switch between root (sudo) and your user, you may have to rebuild images more often than you thought.
    And of course there's the gotchas you mentioned with ports etc, which can also make it painful to follow guides. I've also seen some subtle differences in how Podman build and Docker build interpret Docker images (such as the copy command, I beliefe the difference was how they treat directories with or without a following slash). Usually not to hard to work around, but difficult to spot, and can make it annoying if you want to distribute a containerfile to others that may have another engine, and are not super familiar with containers.

    • @joergsonnenberger6836
      @joergsonnenberger6836 Před 3 měsíci +1

      Why timers? A regular systemd unit works just fine to start containers at boot. Been doing that in SuSE's MicroOS for a while, works like a charm.

    • @AndrewFrink
      @AndrewFrink Před 3 měsíci

      Was going to say, just use systemd units, or better yet the newer quadlets.

    • @nio804
      @nio804 Před 3 měsíci

      Unless something has changed recently, allowing access to the docker daemon is equivalent to root access (you can just run a privileged container and do whatever you want as root), so multiple users could just as well run podman with sudo to share images, or use the docker daemon emulation layer that provides a docker socket.

    • @scheimong
      @scheimong Před 3 měsíci

      Most distros' podman package ships `podman-restart.service`. Enabling it is the easiest and laziest way to get your containers starting on boot.
      If you want to do it "properly" though, use quadlets. You get all the benefits of a systemd-managed service with it too. Migrating is made easy thanks to the `podlet` project.

    Unfortunately podman compose isn’t a replacement for docker compose and apparently not well maintained :( yes, it might support very very basic use cases, but if you have more than few lines of code in compose file most likely something won’t work (and good for you if you notice that because of an error, not silently ignoring fields from a file)
