I switched from Docker to Podman since few months, never looked back. Had some headaches to convert some containers but it is very reliable and compatible with kubernetes.

I've been using Podman for years now. I really appreciate that its user namespaced and doesn't require a daemon to run. Thanks for covering it! Hope to see more tech youtubers dropping "Docker" when talking about containers and just referring to them as containers. Docker's not the only game in town.

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."

That is a bit of the finger to docker. I love that! Docker went the Oracle route, and tries to charge every corporation user with a docker desktop license. Portman looks super simple and never unterestimate the security aspect.

Switched to Podman 2 years ago now, never looked back! Thanks for the video.

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. 🙂

I used Podman last year at my then-employment. I see a lot of improvements. That is very much welcome. Nice app. A good replacement for Docker Desktop, which is what makes many companies not wanting to use Docker. Podman UI really is cleaner.

Honestly, I never thought about changing from Docker to Podman, but this POD creation is really catching my attention, I had some experience building sidecars for containers and is a PITA to test it locally with docker. Awesome content.

I wanted to get into containers, but could not risk installing docker desktop on my work pc due to any license consequenses. Really happy with podman! Can do everything i see people doing with docker.

Finally. Been using some of your videos to implement with podman for the reasons you have mentioned. Never have had any issues with podman-compose btw. Keep up the superb work. Cheers.

Switched in April 23 when I moved to Fedora. Difference is it can be backup-ed and restored from tars and it needs dealing with effective user and group IDs and creating user session during system startup and there are some special commands to move files into and from volumes.

Think I'll stick with Docker for now but pretty interested especially given the integration of docker-compose types of container deployments. Think i'll spin up a test VM and give Podman a try. Also.. Docker Scout video, Please and thank you!

You said 'rootless' and I immediately got confused with the older use of that term from X-Windows. Thanks for the flashback! 🙂

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 admire what you do Christian. keep it up Lempa

I’m made to switch from docker to Podman about a year ago, I issue have most of the time is a hard coded docker deamon socket in some projects, making a symlink + activating the podman socket will do the trick most of the time. Running podman rootless by default and managing containers as systemd services is a great features

This is an excellent video! I’ve also been debating on trying Podman and I think this definitely helped. I will definitely be giving it a try for local container testing.

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.

Very focused on Desktop usage on Win and Mac.

Thank you for pointing out this. I am pretty sure it helps the community! Best Regards!

Your head looks very smooth. Very nice.

Of course there is always nerdctl as the CLI and Rancher Desk as the GUI. Nerdctl can be run either rootful, or rootless and does more then Podman or Docker as an interface to containerd.

Migrating from Docker to Podman is a headache! Especially if you use docker compose!

Great video, thanks, I'm going to try podman tomorrow at work and see how it also fares at building and pushing docker images :)

I currently use Podman for all my containers. However, I found one things which is a tremendours headache with Podman: It doesn't play nice with NFS mounts. NFS assumes UIDs are synced between server and client, and the whole subuid things totally flies in the face of that. I just said "screw that" and just mounted my storage using iSCSI... but that comes with a whole set of new problems 😂

OpenShift would be quite cool to see featured in a video, in particular it's open source version called OKD

Yes, I would definitely like to learn about Docker Scout.

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 😀).

I was going to switch to Podman, but then I was overtaken by a compatibility problem with the devcontainer in vscode, which is why the migration plans had to be postponed on my work PC. But among the newer solutions, I’m currently trying finch from AWS, which uses lima, nerdctl internally. I recommend you try it. Thank you for the video.

1:47 In keeping with its mascot, PodMan has seal-eye tools. 🥁📀 (I'll show myself out.)

I'm curious about the terminal application you use, is it Mac Exclusive?

4:36 For me lack of proper support of compose files was the only reason which stopped me from using podman some time ago. I don't like imperative docker, i like to use compose files much more, even for simple apps. When i tried podman it still had some issues with some yaml sections about resources limits and so on (don't remember exactly) and also with .override files. But it was few years ago, maybe it's time to give it another chance

Thanks for the demo and info, have a great day

one thing I don't much like about your videos is that you always focus on GUIs which is good for local development but not really important for real environments and real work where CLI commands are mostly used, that said, thanks for the introduction about podman I will definitely try it and read more about it.

I've been using Jenkins running under Docker for a few years with Dind such the build tools (Like Java and Maven) themselves run as Docker containers. I've started using the Kubernetes Jenkins plugin so that those same containerized build tools are now running as Kubernetes pods. Well the problem is that in order to support multi-arch container builds I'm using the Jenkins Docker Pipeline plugin and docker buildx to build the multi-arch images and that seems problematic for running under Kubernetes. So now I'm working on using a containerized install of Podman which I'll be able to invoke as a Jenkins Inbound Agent to be able to do my multi-arch container builds as Kubernetes pods. Once all that is accomplished I'll end up moving Jenkins from Docker to Kubernetes.

Brother's you always provide good content for us thanks for such type of informative content...

I have one word. QUADLET. I've met the developer of Podman, and have attended a few of his seminars.

Scout YES!❤

using podman exclusively since 3 years. Running rootless just rocks on our prod servers but also locally on my laptop.

The company I work at recently dropped Docker because of the license issue and it’s been a pain in the ass. I’ll take a look at this

Pretty cool stuff. I’m currently reading through Podman documentation from Red Hat learning how to use it.

I'm still getting first-hand experience with containers. I'd like to learn to be proficient with Podman more than Docker, but I haven't been able to find a single homelab project I'd want to do whose guide for deploying a container was written for Podman, lol.

for mac silicon user, I switched from Docker to Orbstack for better performance since it use rosetta instread on qemu

I love podman for using kube files directly instead of docker-compose

The developer urge to make new, faster, better, safer applications/frameworks instead of helping improving the existing ones

Tried podman a while ago, hated it so much i stopped after 40h. Bad documentation, not everything was supported, problems with setting multiple ports.

Great video, now I would like to try Podman XD

Where can one locate the VSCode extension that you're using to craft a Pod manifest? Love the video and I'll definitely give Podman a go.

AFAIK, docker is also using namespace separation, main vulnerability is misconfiguration or providing excessive privileges for the container. I suppose the same happens in podman as well.

I switched from Docker to Orbstack, some grails tests (from the language groovy) running through a docker desktop it takes 3 minutes and running through orbstack it takes 1 minute

Are all problems with devcontainer from VSCode solved? Can you now use podman with devcontainers?

Ive been using podman instead of docker for a while now and its served its purpose excellently. The only annoyance i have wkth it is i csn't just set containers to restart: always and have them come up on the boot of the host. I know i can generate systemd files to do this or use quadlet to make simpler syatemd files but both of those require extra setup whereas under docker I could simply set the restart parameter and the containers would start on boot

the compose is very bad in podman

many network issue on windows. 1. port redirct not registered in firewall so the port cannot be accessed from other device 2. cannot access port on parent so it is the best to deploy basic service like redis, mysql etc on podman

I need compose files and IDE Integrations. Therefore, docker is still my preferred solution.

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.

Thank you.

I made the swich like two years ago, start to use inmutable linux distros and they comes with Podmam by default, using distrobox also has been a game changer for me. About the Portainer and Podman Desktop thinks, i really dont use any of them

I don't understand why podman desktop isn't available as a webui like portainer

13:15 are you having earthquake? :) Good video btw, thank you. That pod k8s functionality is what really made me consider trying podman.

I personally use Rancher desktop which also supports Kubernetes.

but how do i seach for images in podman like i do in docker desktop .......

What do you use to theme your terminal? I would love to achieve something similar on Linux. The separators between commands really work well with my brain.

Podman binary seems to be updated only for redhat distribution. Other distro the version is quite old. Latest version of podman is 4.9 as of today.

Hi Christian, thanks for great explanation. but, may i know how and what is the configuration of your terminal so the result are displayed on the bottom while the input is still in the top ? thanks

I've been using podman for distrobox

A very interesting argument, I will look up to podman in the near future. Another question: what terminal are you currently using?

many dev tools still prefer docker and just not work in podman, so i save the headache since to just using docker

My experience with Podman isn't as good as with Docker. I feel like Podman is not fully finished, I have experienced some bugs with it.

so i should start learning podman as well?

I've been interested in the security benefits of podman for a little while now, but I'm a bit worried about potential issues when trying to use podman to run a reverse proxy since you often see issues when you don't open ports 80 and 443 for them. I'd be curious to see a successful implementation of traefik in podman

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)

Running a buch of docker containers on my servers, diden't hear about Podman before, gling to try it out.

i wonder why no one uses podman for supabase

Unfortunately does of us who manage thousands of docker container applications cannot simply abandon docker when a new challenger comes along: and there will be many appearing in the next decade.

If you run single containers as services - Podman is great. If you spin up applications as integrated services there is no better solution than docker compose

If you want to use a port lower that 1024 without running as root, then you can redirect traffic from a one port to another via a firewall rule. Here is the example for iptables. ```sudo iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 21 -j REDIRECT --to-port 2121```

Looking forward to a new series of Kubernetes video!!

Yes, Docker Scout for SBOM please !!

I have a question about what security priority is appropriate for Linux vs Windows vs Mac OS

I would love to switch but podman networking still has some major issues - for me at least.

Been using pod man in prod since 2020.

I am on Mac OSX Sonoma with M1

It all come down to user choose or they can try two way while working on their projects. It nice to expand some skills.

Good video as usual. 👌

Do a video about Jobs, Cron Jobs, Daily Schedules the best softwares to use in a homelab with web panels

Podman doesn’t work with the :Z option on OSX which makes it incompatible with Ansible-navigator There is a known issue that won’t be fixed. If you need Ansible on OSX then you need docker not podman

Remember to keep SELinux enabled

Yes bring on scout

Podman is hard on mac silicon. Barely ever runs and certain containers are impossible

I did the reverse, I was using podman for a year or so but really never got into the advanced features due to having to fight with SELinux and stuff like that to get various software running and it was rootful anyway. I know docker is a little bit less secure, though is there really a difference when comparing both used in root mode? At the end of the day, a docker installation is just easier to maintain when there is a much bigger community around it

Hmmmm. Lack of "compose" style files... that might be a deal killer for me.

Can podman use the Docker Images in The Docker hub?

With docker desktop I need to be logged in to run my containers in Windows. With podman will it run more like service so I can reboot and expect pods to run straight away?

Struggled with podman networking vs docker. Docker simple to create a private bridge network that a few containers connect to. Podman pod networks expose all listening ports to public.

The only thing preventing me from migrating to Podman is incompatibility with dev containers features.

Docker scout, for sure!!!!

you can also alias docker to podman so you don't even have to remember to type podman

I love the video , I'm trying to use docker in freebsd but it is not officially supported and podman fits well for me can you please make a video on how to migrate docker container to podman it would be really helpful to actually consider giving it a shot.

But you can use kubernets yamls instead for docker compose files and podman does not run as root by default!
