Podman vs. Docker

[@bojackhorsingaround]

Not having swarm for container orchestration with podman isn't much of a bad tradeoff because podman works seamlessly with kubernetes - which is one of the best orchestration tools in the market.

[@janusz1697]

Kubernetes is deprecating Docker as a container runtime after v1.20.

[@newerest1]

​@@janusz1697You do not need to panic. It’s not as dramatic as it sounds. TL;DR Docker as an underlying runtime is being deprecated in favor of runtimes that use the Container Runtime Interface (CRI) created for Kubernetes. Docker-produced images will continue to work in your cluster with all runtimes, as they always have.

[@ayanmukherjee3102]

Not many people used Docker swarm now whether docker or podman kubernetes has become the industry standard

Beatifull video and awesome presentation! Congrats, Cedric! 🔥🔥🔥

[@rmm2138]

Thank you. In less then 7 minutes you provided enough detail understand the main differences. Now I need to do more exploring on Podman. As of right now, I am a Docker person :-)

[@MarkASear]

I love how cool these videos look (and the content also). Would it be possible to explain how you achieve this? I love how you can write on glass etc. but cant work out exactly how you do it.

[@IBMTechnology]

See ibm.biz/write-backwards

[@Openwrt2023]

It is done with a lighted board and neon markers. The camera is 180-degree phase shifted, i.e. mirror image.

[@Oleksii_Ukraine]

I heard about podman long time ago but never used. Then, after struggling with docker setup under WSL (just a docker, instead of docker for windows as it require license now) - I tried a podman. And had no issues with it as it doesn't require daemon service, that might be a problem for Windows WSL. Also with docker alias it seems that all docker commands work as expected, so I like podman approach much more, and probably will try to use it more in future.

[@SrinivasNirvana]

Amazing video and the presentation, Using Podman(PodManager) of added advantages when using the k8s. I think we can even test containers by scaling up and scaling out at pod level using podman, you need docker swarm to test the same.

[@nazrulhadinazlan1983]

I'm more amaze that he's able to mirror writing neatly

[@michalhudek]

if you believe that podman can do its magic, its easy to believe that computer technology allows to flip image vertically

[@animanaut]

i guess IBM is Team Podman since it is from Red Hat?

[@mihaibob7902]

They have bought Red Had

[@ubaydulloh1000]

Thanks Cedric, nice presentation. I would like to try Podman

[@FerShibli]

I'm a Docker guy, but after this explanation I feel like changing to Team PodMan

[@_bxffour]

It imitates the docker interface. You can alias it to docker and forget about it

[@AmitPawar-p5o]

nice and clear informative video

[@ashypeshy]

Team Docker Thanks for the presentation (inspite of the fact that you mentioned that you work at Redhat), you did not push for podman. I need to experiment with podman soon

[@cycletechsa]

Thanks Madala

[@shafiq_ramli]

Have yet to try podman. Really nice presentation 👍🏻

[@timothyelems1357]

Runs smoothly! Does not task your system whatsoever!

[@SteveSpeicher]

Nice work Cedric! I’m team Podman! (of course)

[@stevanlemeur8070]

☺

[@sephyshen2510]

Thanks, team. The video is very informative. It gives me the power to switch the container engine from Docker to Podman.

[@flesz_]

it's amazing how kids are teaching adults now

[@bazejczuk8972]

Docker but after watching this movie and analysis current and fueature architectur, I started thinking about podman, propably It will give me some namespace features. I have to start play with Podman ❤

[@janusz1697]

Hi, I'm also from Poland

[@alex.prodigy]

not to take anything away from podman , but there's also docker rootless albeit not the default installation mode team docker on my workstation simply because there's not podman package maintained afaik for debian based systems

[@Iswimandrun]

I am new to docker and podman. I basically know how to make MQTT brokers using mosquitto container image, a docker compose yaml file, and how to make a systemd service for both to boot the container at start.

[@Iswimandrun]

Yea podman uses the same docker compose file.

[@Artist19]

Currently learning Podman

[@clashclan4739]

Which is more efficient in terms of cpu, ram, network and load balancing

[@danielwalsh2363]

Since Podman can go away when a container is running, and does so any time you daemonize a container (podman run -d ...) Then Podman does not use any CPU/RAM or Network when containers are in steady state. Usually people leave Docker daemon as well as containerd running, so it uses CPU and RAM when the system is just running containers. As far as containers are concerned you should see no difference between a running Podman container or Docker container.

[@AbrahamPanicker]

Very well explained !!

[@kishanbsh]

How long till redhat puts podman behind a paywall?

[@ifnw0425]

I have a problem where my podman container is stopped after sometime i disconnect fron the server, is there any way to prevent it?

[@seeemawn]

Can someone tell me the difference between docker compose and these podman pods? To your question: I use docker containers for small services, but I am interested in using podman. I like this clicki-bunti-copilot-approach.

[@johnmoxen620]

Thanks for this succinct explanation. I'm new to the Tech industry and am learning on the fly. Any suggestions about how I can best get started? Thanks!

[@flesz_]

tons of free time, plenty of motivation, reading documentation or videos whichever works better for you and most importantly practice

[@cloudnativecedric]

Hello John! Sorry for the late reply, but like Flesz said, lots of free time 😅 with the popularity of containers and microservices, I’d recommend a certification from The Linux Foundation, specifically the CKAD, Certified Kubernetes Application Developer, to get started. There’s various ways to study (free and not-free), but it’s a great way to start learning and get a lot of hands-on experience!

[@ritas6971]

actually podman team :) nice presentation, thanks

[@YoyoYo0877]

the only 2 lacks podman has IMHO are: 1. no 1 to 1 docker composé file compatibility 2. no host network option...

[@danielwalsh2363]

Podman has the ability to manage networks, with the same commands as Docker. podman network ... Rootless containers are more limited, because of some constaints of the Linux kernel on rootless users, but with pasta network service, you can get to most controls.

[@lever1209]

this video is more for management than engineers, doesnt have many details and just goes over the basics, name dropping a few other programs

[@peaps]

What's more impressive is the ability to write in mirror image

[@MrVnelis]

Really good video. Thanks! I haven't tried podman yet, how does the storage work? Is there a podmanhub or something similar to which I can publish my images and pull them from my k8s?

[@alex-g7q1m]

Nice video!

[@monjioilita]

Podman looks cool

[@aswilled1]

Love it nice break down

[@rohiniswami6602]

Someone knows how to test aws lambdas on local using podman instead of docker

[@floratextile9910]

hi i want to learn how to install frappe erpnext installation in podman, annd make it to access my domain name dns record..

[@CesarParedes-u8l]

Great Presentation.......... I am a Docker guy..............Thanks........ :) bye

[@faelpinho]

Very good video! I already tried both in my linux (Manjaro) and Win10. In my opinion, using Windows, Docker is complete and very useful. Using linux and Portainer, no difference.

[@chalmeres]

Muito bom o conteúdo!!

[@wesleyp6281]

I'm team Cedric 👑😍

[@TumbleGamerTK]

Could i use podman on my local machine and the deploy them to a server with docker?

[@biscotty6669]

Yes, podman images are fully compatible with docker.

[@YannMetalhead]

Good video.

[@winfle]

Swarm is a beast

[@vivekkaushik9508]

Podman baby

🙌

[@davejones542]

I am team Dockman (both)

[@whatrobot]

Team Podman! I prefer the architecture and principles. Containerfile FTW!

[@alexvajith5889]

Wait how is he managing to mirror write contents without any mistakes??

[@tony7682]

What is it that you are writing in the hexagons at the top of both columns? T3? JS? Hard to read the hand writing.

[@testertech]

Trying to become team Podman more and more! Thanks for the clear explanation. I would also advise the book Podman in Action 📑by Daniel J Walsh for anyone wanting a more detailed comparison.

[@kitersrefuge7353]

Just tried Podman on my desktop. Failed to install...looks chaotic the UI. Back to Docker Desktop I run.

[@la1858]

I don’t know which team i’m on yet 😢

[@bobanmilisavljevic7857]

Nice job! 💪🧙‍♂️🌌⌨️

[@cariyaputta]

Danny Gonzalez?

[@iCrimzon]

I saw his face and thought that as well, i guess everyone has a non related relative somewhere in the world

[@angelamidev]

I was in team Docker but now I am in team PodMAn!

[@shawnkec]

Nice

[@mind-blowing_tumbleweed]

podman compose kinda sucks - it's just some unofficial python script. not having it fully supported is a huge drawback for local development.

[@biscotty6669]

Podman compose only exists to allow compatibility with Docker. It's not part of the normal workflow. Pods make it unnecessary. You manage them the same way you manage simple images, just adding '--pod' to the command mainly. Podman simplifies everything.

[@mind-blowing_tumbleweed]

@@biscotty6669 you just called the whole concept of compose files unnecessary. It's far from it.

[@nobody.watchin]

Team podman all the way, containerize everything!

[@SvenKohlhaas]

Team Podman!

[@felix9150]

team podman!!

[@Awesome2844]

I CHOOSE PACMAN!! 😅😅😅

[@mariobader2152]

but where is podman? In most companies you won't find Docker yet, but Podman 😉

[@iftikhar58]

it base on objective , I am Data Scientist and i will prefer Docker

[@parraes]

Team podman

[@RajinderYadav]

why is he talking about docker swarm? that project was abandonded a lot time ago. most people use kuberneties for container management. I got a feeling he doesn't really got a handle comparing docker and podman, in his checkmark he miss securities. 🙄

[@jamessondecastro5785]

Thanks for the video, Honestly I'm having trouble creating Docker Compose with my Web Application that running multiple python scripts, I wonder if Podman will do the work, I want to give it a try.

[@bjbegui]

Team podman all the way

[@biscotty6669]

Team nix, really. But definitely Podman over Docker. The lack of a daemon Is enough of a reason.

[@mehtahrishi]

@Podman

[@TrungLê-k8g]

I have been using podman for 3 years. Seriously I could never go back to docker.

[@PerEng2405]

Podman-

[@drax2gma]

Neither. Distrobox :)

[@robinkramer7988]

docker is better :)

[@charlesdean03]

I am more in the podman before this whole herd effect started. Also what is this an H&M advertise? Also he is being goofy for no reason you can do this without making weird faces? or is it his personality dont get it.

[@s.i.m.c.a]

Ironically, k8s cant use podman as engine...but docker no problem.

[@jeanlecox]

Kubernetes uses Container Runtime Interface (CRI). The idea behind all with Podman is to split the codebase in multiple projects (vs monolithic Docker approach) for specific purposes and the CRI implementation is project CRI-O, so Kubernetes uses CRI-O. Kubernetes used docker-shim in the past but that has been deprecated as non standard. Today it uses containerd IIRC. Podman makes easier deploying to Kubernetes, but Kubernetes itself runs containers with CRI interface so one possible option is CRI-O. Both Podman and CRI-O use runc/crun to talk to the Linux kernel in order to run containers. Hope it helps clarifying!

[@danielwalsh2363]

Podman supports running kubernetes YAML file natively using podman kube play. This makes it easy to take kubernetes workloads and launch them on your host machine without requiring kubernetes at all. Similarly Podman can generate kubernetes.YAML files directly from locally running containers and Pods using podman kube generate. Finally podman kube deploy can actually take locally running containers and pods and launch them directly into a kubernetes cluster. Specicially kubernetes (kubectl) does not interact directly with Podman, but uses CRI-O which is a daemon based on the same underlying libraries and storage as Podman.

[@SeanAhern1]

Please, please, stop saying "DAY-MON"! The words "daemon" and "demon" are different spellings of the same word, pronounced the same, and meaning the same. It's simply said "DEE-MON".

[@biscotty6669]

In English the 'right' way to pronounce a word is simply the way people pronounce the word. When enough people start saying a word differently it makes it into dictionaries (like the alternate pronunciation of daemon has). Many native English speakers say daymen or deh-mon... you say tomayto I say tomahto ...
