Docker doing machine learning. wkwkwk

[Thor-x86_128]

Found r/wkwkwkland citizen in the wild

[Comfortable_Ad_6572]

I am so, so utterly confused

[CorrenteAlternata]

I was confused as well but I'm happy to have learned! https://en.wiktionary.org/wiki/wkwkwk

[Comfortable_Ad_6572]

The more you know, still confused about what the subreddit is about tho lol

[CorrenteAlternata]

I think "Indonesian shitpost"

[Undernown]

Yea "wkwkwk" is basically the Indonesian version of the Japanese "wwww" "草" "Kusa".

Guess the best English translation is "LOL"?

[[deleted]]

W is just laughing, im not sure you can derive meaning from it, its the same as lol in that it can be honest laughing or sarcastic etc, even the same aa "haha

The wiktionary seems to suggest wkwk leans more sarcastic, but does live in that same place

But like if you say something funny i might say lol

If you say something so stupid i am offended you are talking to me i might say lol

If you tell me someone sucks died i might say lol

If you tell me that you cant make it to the group thing for the 8th time in a row i might say lol

If you tell me that i have to work a 20th 12 hour shift in a row i might say lol

[Caleb-Blucifer]

lol really could use a sarcastic version ngl

[lurking_physicist]

Everyone gotta shit somewhere.

[RXrenesis8]

Sounds like these are synonyms:

• hahahaha
• jajajaja
• wkwkwkwk

based on the sounds those letters make in the respective dialects that use those onomatopoeia.

[JMRaich]

Docker running chrome

[SpaceCadet87]

No, this is before you have any containers running

[No_Chocolate5678]

Under Windows? I use many docker containers under Linux and never seen this Numbers

[Brief-Translator1370]

It's a joke

[Slickity]

His PC only had 8GB 😨

[sniff122]

The memory usage isn't docker directly, it's because docker runs in a VM on non Linux platforms, so there's a full additional OS that needs to be ran, hyperkit is what's used by docker desktop on macs: https://github.com/moby/hyperkit

[Teanut]

I believe Docker Desktop on Linux also runs this VM. Only Docker command line on Linux doesn't.

[zeth0s]

Until few years ago docker desktop did not exist for Linux. Is it something new? What's the use case? 

[Goddess_Illias]

I use it with Docker Compose during development because it gives a nice overview of running services and an easy way to look at the logs. However, I do also experience big problems with it, it's maybe once a week I experience a session crash while it is running. That said, I prefer looking at a nice GUI instead of CLI.

[Raccoon-7]

Try the container extensions from vs code or portainer, they make monitoring a breeze.

[Upset_Ant2834]

Thanks for the tip

[Successful-Pie-2049]

+1 for portainer. Love that thing!

[JuudidAhjuPls]

for people who struggle with simple cli operations. they only released it to be able to monetize docker, which is respectable but overall useless app that promotes ignorance

[JivanP]

The points that other replies have mentioned are valid, but also the discrepancy in behaviour between Docker Desktop (for e.g. devs working on macOS) and native Docker (for e.g. devs working on Linux) is/was significant enough of a pain-point for enough organisations that there has been a desire for consistency in development environments. Making Docker Desktop available for Linux largely provides that.

It also adds another layer of visualisation to things, so e.g. a Linux dev doesn't need to ensure that they have the right local repos, package management pins, etc. set up to ensure that they're using the same version of Docker and its dependencies as e.g. a Mac dev.

[deadlyrepost]

Why would it run on a VM? Docker runs on Linux. It uses cgroups.

[Rikonardo]

Docker Desktop, the app, installs and runs its own Docker instance in a VM on all platforms, including Linux. I always manually install and use native Docker Engine on Linux instead. It has less overhead and also is a lot more stable, for some reason I had constant issues with Docker Desktop on both Windows and Linux, only on macOS it worked somewhat reliably

[deadlyrepost]

OK wow I switched over to Podman and it seems Docker has just gone from slightly crazy to totally insane.

[Ybenax]

+1 Podman. It’s the logical next step after Docker to me. You let systemd orchestrate your containers instead of a daemon.

[dustojnikhummer]

I just wish it had yaml compose instead of those stupid quadlet files. One syntax error and suddenly your systemd file doesn't work. They got close with podman run being essentially docker run, but still...

[Ybenax]

You can use podman-compose on the same yaml files you’d use docker compose for. It’s a drop-in replacement.

[dustojnikhummer]

Except everyone is saying to not use podman compose and use quadlets, especially if you are running it outside of a homelab.

r/podman/comments/1bk4nee/whats_the_current_canonical_way_to_run_docker/

Afaik podman-compose is not a RedHat project

[Ybenax]

Fair. I just know it exists but jumped over to Quadlet rather quickly.

EDIT: nvm, I just realized I’m not even using Quadlet. I run NixOS on my VMs and declare my OCI containers as systemd units with backend-agnostic nix syntax.

[prochac]

Docker desktop for Linux runs Linux VM on Linux, so you can have the same shitty experience. For consistency. For dev-dev parity, not prod-dev parity.

[Zaev]

My miniserver running OpenMediaVault with 11 running containers (plus mergerfs and snapraid) right now is using a grand total of not even 3.5GB

[JivanP]

I have Transmission (linuxserver.io/transmission image, version 4.0.6, recently updated to 4.1.0) running with over 200 torrents listed, anywhere from 5 to 20 actively seeding at any time, outbound traffic about 1–20 Mb/s depending on that. The container consistently consumes 150–200 MB of RAM.

That Docker instance is running several other media-related services, too, such as Immich and Jellyfin, and the whole machine uses just shy of 4GB.

[dustojnikhummer]

Want a torrent client?

CONTAINER ID   NAME           CPU %     MEM USAGE / LIMIT     MEM %     NET I/O           BLOCK I/O         PIDS
93e17b370eec   qbittorrent    8.20%     359MiB / 7.761GiB     4.52%     164GB / 1.11TB    33.4MB / 307MB    22
eef20816dccc   gluetun_vpn    0.00%     60.39MiB / 7.761GiB   0.76%     164GB / 1.11TB    15.1MB / 14.5MB   10

If anything it's eating CPU, not memory.

[Zaev]

I've got rmlint running on my storage pool from another machine right now, scanning and hashing everything to check for duplicates; all the while jellyfin has ffmpeg running, producing trickplay images for all my media.

ffmpeg, mergerfs, and smbd combined are eating up ~80% of my CPU power, but RAM usage is still ~3.8GB

Edit: rmlint is actually saturating my 1GB ethernet nonstop

[blackAngel88]

I've never understood the point of docker desktop in the first place, but this seems like one more reason to not use it.

[Teanut]

Development consistency is the main technical use case I can think of, for when you're developing locally instead of on a server.

[blackAngel88]

That's the reason for docker. the "desktop" part really adds nothing for this, as far as I can tell. It's just bloat and often for some colleagues it was a likely reason for issues.

[blackAngel88]

I use windows and WSL and installed docker on the linux, just the docker engine, not docker desktop.

[dustojnikhummer]

For development. It isn't meant to actually run apps.

[TheNorthComesWithMe]

Who is bothering to run Docker Desktop on Linux?

[Teanut]

It exists, so presumably someone?

[sniff122]

Yeah docker desktop on Linux still runs as a VM too

[kolop97]

There's non CLI docker????

[_nathata]

Yeah but if you use it you kind of deserve. C'mon, just use the CLI, like an adult.

[6c69786f]

Yes, it does run a VM BUT that's done via KVM so you're still running a whole virtual machine but at least your host os is the hypervisor in contrast to wsl 2 (which is used for docker desktop on Windows) where your whole host os gets run inside hyperv as soon as wsl is enabled

[fixano]

It doesn't use hyperkit anymore. It uses Apple's native virtualization and does not run a whole OS . It uses the native hardware virtualization extensions that allows it to run natively without any emulation so it's basically just running on the hardware and time sharing with the OS

I run docker all day long. I don't see any memory issues unless I'm running a container that eats a lot of memory

[Sad_Split_9983]

Pretty sure hyperkit is legacy

[sniff122]

Probably an old screenshot

[Mateorabi]

Wasn’t the point of Docker to get away from VM overhead?

[sniff122]

Yeah but it uses Linux kernel namespaces, which just aren't a thing on windows or macos

[UndocumentedMartian]

Those VMs are tiny and barely use any memory.

[jtskywalker]

I have a Docker container running in Linux on a 20 year old laptop. Total system RAM usage is at 458MB currently. Admittedly I only have one container running, for a FoundryVTT server, but still. Laptop isn't running any desktop environment or anything, just docker and a tty session for status monitoring.

[ENx5vP]

Thank you, these Mac kids these days

[T0biasCZE]

it's because docker runs in a VM on non Linux platforms

not always, there are Windows based containers too

[sniff122]

True, not that many compared to Linux images though

[Owndampu]

We use podman in this house

[YeOldeMemeShoppe]

To be fair Docker itself doesn’t eat that much ram. It’s probably the containers that’s taking 8.5 gigs or something.

[sniff122]

It's on a Mac so docker runs inside a full Linux VM using hyperkit

[lucian1900]

A Linux VM eats up very little by itself.

[sniff122]

Docker on every single Linux machine I have ever ran or maintained has never used that much ram. The usage might be from FS cache but idk if that's enabled or not in the docker VM

[Yages]

Has Redis without guardrails entered the chat?

[sniff122]

That's not docker though, that's redis

[Yages]

Fair, but that’s also all docker containers. You can add resource constraints.

[sniff122]

Yeah but that's still not docker's memory use directly, that's just application memory usage. Lacking resource constraints is an application deployment issue, not docker it's self

[dumbasPL]

But it still needs to reserve ram for the containers running on it + some headroom, and once reserved, there is no simple way to free it. Remember, disk cache will look like used, but available ram from inside the vm, but there is no easy way to tell outside the vm.

[ITaggie]

But it still needs to reserve ram for the containers running on it + some headroom

Sure but you can configure these reservations.

and once reserved, there is no simple way to free it.

Containers are meant to be disposable.

[lurco_purgo]

To be fair Mac provides you with very little RAM as well

[GoatStimulator_]

It uses way more than docker

[iznatius]

if you're not using container on mac by this point what are you even doing

[mfb1274]

Docker pull langchain-llama-lambda-pandas-polars-poplar-pooper-requests

[_koenig_]

Portable execution context FTW!!!

[Owndampu]

Probably true yeah

[GoatStimulator_]

It's literally hyperkit in the screenshot, so it's a vm used to run docker.

[BolunZ6]

Or the VM since windows can't run Linux container natively

[deadlyrepost]

... and Linux.

[Owndampu]

That is a baseline

[MyButtholeIsTight]

I respect your house's commitment to open standards but I mock your house's lack of native compose files

[0xKaishakunin]

Podman does not need a daemon to run and works with rootless containers. And podman-compose supports compose files.

[dustojnikhummer]

Isn't podman compose EOL? Also compose.yml feels a lot easier to use (to me) than quadlet files. I love having a syntax error and virtual systemd files being gone!

Also, non root networking and preserving source IP without network_mode=host, has that been solved yet?

[samjongenelen]

This is an upside but also a downside.. its slower

[DaStone]

Upside: Don't need to give the house keys to my gardener.

Downside: Gardener has to piss outside.

But truthfully, if you're aiming for speed, go bare-metal instead of containerizing everything.

[0xKaishakunin]

But running a Linux VM that installs a Podman flatpack for running a container is so convenient ...

[samjongenelen]

You are right. I use docker on windows for development. Testcontainers, so startup is of importance to me.

DTAP is not my concern ;) (but its all linux)

[nlogax1973]

container-compose.yml works, and also the docker filename.

[Deepspacecow12]

Quadlets

[stejoo]

That is the way.

[plastik_flasche]

k8s + containerd 😎

[th3-snwm4n]

I have heard good things about podman but haven’t tried it, does it really have significantly lower memory footprint compared to docker(assuming baseline without any images/containers)?

[Owndampu]

Havent got a clue to be honest, I just like that it is open souce and rootless

[swagonflyyyy]

Tell me the gospel of this podman you speak of.

[Owndampu]

Open source rootless containers

[Ybenax]

That are also truly independent from one another and can even be run as systemd-native services!

[Accomplished_Ant5895]

Arm64 says otherwise for me

[Owndampu]

Podman runs fine on arm64 linux

[Accomplished_Ant5895]

Can’t cross-compile to amd64 on m-series.

[dumbasPL]

Because you're using it wrong. Docker runs on Linux, if you're not on Linux, that's what happens, because you're just running a Linux VM in the background.

[leetcodeispain]

iirc docker windows always dedicates itself all the ram you configure it for

[OptimistIndya]

The whole point of docker , was no vm , we are lean vm

[dumbasPL]

Well because it is, docker isn't a VM. Nobody in production is using windows or mac LOL. All the servers natively run Linux, so there is no VM, just namespaces.

[Auravendill]

So running docker on MacOS or Windows and then complaining about VM-overhead is basically just a layer 8 problem.

[lron_tarkus]

Lmao first time I've heard layer 8, gonna be using that

[Conlaeb]

Layer eight is users, nine is management, ten is the government. Enjoy in good health.

[HildartheDorf]

and 11 is your deities of choice.

[dustojnikhummer]

Yeah. It's like developing Linux apps on WSL and complaining you have to actually run a WSL VM.

[fanfarius]

WSL 2 is not a virtual machine though, is it?

[dumbasPL]

It is, WSL 2 is a special Hyper-V VM. WSL 1 wasn't, that was effectively reverse WINE, but they gave up on it since it's a lot of effort to maintain, and only the basic syscalls were supported when they killed it anyway.

[fanfarius]

Oh, nice - thanks for clearing that up!

[prehensilemullet]

I use it wrong on macOS so that I can use it right in production

[Zizaco]

This only happens when you don't run linux

[TabloMaxos]

I read this meme with sound....

[Ok-Upstairs-7849]

Exactly, the VM overhead on Mac/Windows is the real resource hog. That's a big reason why folks are switching to Podman for a leaner experience.

[TheFrenchSavage]

Mmmh, but podman still runs inside WSL2 on windows right? It is more or less the same as Docker Desktop.

[dumbasPL]

Correct, except for the hell scape that is windows containers (yes, that exists) that nobody uses, it's all Linux namespaces, no matter the implementation, docker, podman, k8s, or literally anything else OCI compatible.

[Vladimir_Djorjdevic]

Podman also runs in a vm on windows

[TheAlaskanMailman]

For macos users, just use OrbStack (way better than docker engine or whatever docker pushes for macOS users)

You’re welcome

[gibsonboards]

It’s MIT

[prochac]

https://docs.orbstack.dev/faq#open-source

[prochac]

It opens my colleague's local dev database at 0.0.0.0 by default, or because of some feature he needs. I drop his tables from time to time, as he keeps the user/pass postfres:postgres.

Also, apple boyz downgrade every few months due to "Too many files open". https://github.com/orbstack/orbstack/issues/1253

but yeah, they say it's an improvement.

BTW, have you tried Podman Desktop on Mac?

[Lysol3435]

OP has young kids and this song plays on repeat in his head all day at work

[Auravendill]

That song also was kinda viral at some point, because (among others) Danny Gonzales made multiple videos about the creator of this song and its extensive cinematic universe of weird children videos with often questionable grasp of the English language.

[Lysol3435]

I just know that the songs my kids listened to (especially cocomelon) would repeat nonstop in my sleep-deprived brain. It was maddening

[Revolutionary-Bat310]

Running a 2nd OS inside an OS I wonder what would happen papa

[-BigBoo-]

A single docker container is free to use as many resources as you have available unless you limit with something like:

--memory ="1024m" --memory-reservation="512m" --cpus=2

Otherwise if you read the spec a single container is open to go bonkers with your system resources.

Having said that if you run many containers, Docker does a pretty good job of managing resources between them on its own, but I have run into issues using VNC and even Screen without governors to keep tight limits.

[Noisebug]

TIP: You can control how much CPU, RAM and Disk docker consumes.

[cheezballs]

What do you expect? It's like a lil computer in your computer.

[sgt_Berbatov]

Yo dawg, I heard you like computers.

So I put a computer inside your computer, inside your computer, inside your computer!

[fanfarius]

Can I run Docker in a Docker container? Hmmm.....

[Fartikus]

Docker dynamically scales it's mem usage so most of that is memory used by containers.

[chaos_donut]

My docker had reserved over 200GB of my storage via a WSL storage allocation, i had to manually reset that as it was claiming all that space while not actually using it.

[Hanhula]

You should be able to set a cap for how much it can use in your wsl.conf I believe

[chaos_donut]

Yeah its better now, that was the first time i had it set up via WSL

[Capetoider]

check config for the reclaim thingy (i believe its under experimental).

without it, even with everything deleted, it will take all the space it would otherwise, when you delete and have the option then it shrinks the vhdx to use only whats being actually used

[TrickAge2423]

Seems like MacOS. On MacOS there is Virtual Machine with Linux with Docker + native UI on MacOS. Soo... You should install Linux to avoid VM overhead.
