Folks, the docker runtime is open source, and not even the only one of its kind. They won’t charge for that. If they tried to make it closed source, everyone would just laugh and switch to one of several completely free alternatives. They charge for hosting images, build time on their build servers, and various “premium” developer tools you don’t need. In fact, you need none of this, you can do all of it yourself on whatever hardware you deem to be good enough. There are also many other hosted alternatives out there.
Docker thinks they have a monopoly, for some reason. If you use the technology, you are probably already aware that they don’t.
If they tried to close source it, someone would just fork it.
Does that include running Windows containers? It seems like the alternatives don’t support those.
Does anybody actually use that feature though?
There are always lost sheep in the fields.
Windows container runtime is free as well, simply install the docker runtime from chocolatey or winget along with the Windows Containers and Hyper-V windows features. This is what we do on some build machines for CI.
Theres no reason to use desktop other than “ease of use”
There are some reasons. Networking can get messed up, so Docker Desktop “fixed that” for you, but the dirty secret is it’s basically a Linux VM with Docker CE and some convenience network routes.
Youre talking about Linux containers on Windows, I think commenter above was referring to windows containers on Windows, which is its own special hell for lucky folks like me.
Otherwise I totally agree. Ive done both setups without docker desktop.
Are You guys really pulling more than 40 images per hour? Isn’t the free one enough?
One of the previous places I worked at had about a dozen outbound IP addresses (company VPN).
We also had 10k developers who all used docker.
We exhausted the rate limit constantly. They paid for an unlimited account and we just would queue an automation that would pull the image and mirror it into the local artifact repo
A enterprise company that has 10k developers should just invest in their own image hub. It’s not really that hard to do. Docker even open-sourced it under Apache2.0.
They did.
Regardless they need a way to pull new ones.
We just build from scratch and pull nothing
Even at work we don’t pull that many, and we have dozens of developers.
Also its 40 per hour per user
On Lemmy, it’s a sin to make money off your work, especially if it is opensource core projects providing paid infrastructure/support. You can only ask for donations and/or quit. No in-between.
A single malfunctioning service that restarts in a loop can exhaust the limit near instantly. And now you can’t bring up any of your services, because you’re blocked.
I’ve been there plenty of times. If you have to rely on docker.io, you better pay up. Running your own NexusRM or Harbor to proxy it can drastically improve your situation though.
Docker is a pile of shit. Steer clear entirely of any of their offerings if possible.
I use docker at home and at work, nexus at work too. I really don’t understand… even a malfunctioning service should not pull the image over and over, there should be a cache… It could be some fringe case, but I have never experienced it.
Ultimately, it doesn’t matter what caused you to be blocked from Docker Hub due to rate-limiting. When you’re in that scenario, it’s most cost efficient to buy your way out.
If you can’t even imagine what would lead up to such a situation, congratulations, because it really sucks.
Yes, there should be a cache. But sometimes people force pull images on service start, to ensure they get the latest “latest” tag. Every tag floats, not just “latest”. Lots of people don’t pin digests in their OCI references. This almost implies wanting to refresh cached tags regularly. Especially when you start critical services, you might pull their tag in case it drifted.
Consider you have multiple hosts in your home lab, all running a good couple services, you roll out that new container runtime upgrade to your network, it resets all caches and restarts all services. Some pulls fail. Some of them are for DNS and other critical services. Suddenly your entire network is down, and you can’t even get on the Internet, because your pihole doesn’t start. You can’t recover, because you’re rate-limited.
I’ve been there a couple of times until I worked on better resilience, but relying on docker.io is still a problem in general. I did pay them for quite some time.
This is only one scenario where their service bit me. As a developer, it gets even more unpleasant, and I’m not talking commercial.
Anyone looking for a free drop in replacement, I’ve been using Rancher Desktop without any issues https://rancherdesktop.io/
I’ve been using podman desktop (https://podman-desktop.io/) which is also free. I’ve never heard of rancher desktop so I’ll have to give that a look!
I second Podman. I’ve been using it recently and find it to be pretty good!
I am getting into Podman but I cannot force my firewall to respect it for some reason.
Rancher is owned by Suse, which is mainly a solid steward in the community.
They also have k8 frontend called Harvestor. It can run VMs directly, which is nice.
Well, there is this one thing: they asked OpenSuse to drop the Suse branding…
Which is fair. Fedora never called itself red hat. CentOS never called itself red hat.
Suse is a pretty good company and deserves the right to their intellectual property and trademarks. OpenSuse shouldn’t make a big deal out of simply changing their name.
They could rename themselves to OpenSusame and keep rolling without any issues whatsoever.
Of course, but I still think it is not very smart from SUSE, since I bet many companies got into SUSE because coworkers had very good experiences with OpenSUSE.
I, at least, if my company would need corporate Linux, would recommend SUSE to my company because of that reason.
I use this as well. I haven’t had any issues.
How does the image scanning compare to docker scout? (Or whatever the docket desktop one is called).
I am exposing docker via tcp in wsl and set the env var on the host to point to it. A bit more manual but if you don’t need anything special, it works too.
So does this setup like a one-node kubernetes cluster on your local machine or something? I didn’t know that was possible.
Basically yes. Rancher Desktop sets up K3s in a VM and gives you a
kubectl
,docker
and a few other binaries preconfigured to talk to that VM. K3s is just a lightweight all-in-one Kubernetes distro that’s relatively easy to set up (of course, you still have to learn Kubernetes so it’s not really easy, just skips the cluster setup).Thanks for the info. For others curious, here’s a decent short intro to K3s.
Now I’m kind of wondering if this is light enough for integration tests.
For integration tests I’d go with kind instead. Use it in my work and it works perfectly in our ci/CD. https://kind.sigs.k8s.io/
How is the transition from docker to podman? I’m using two compose scripts and like 10 containers each. And portainer to comfortably restart stuff on the fly
I can only provide my experience; it was a drop-in replacement. I have 7 services running and 3 db containers. I was able to migrate using the Podman official instructions without issue.
from what I can gather its currently recommended to use quadlets to generate systemd units to achieve what compose was doing. podman compose is a thing but IIRC I didn’t find that was straight drop in and I had to change the syntax or formatting a bit for it to work and from the brief testing I have put in quadlets seems less hassle, but if you use a non systemd distro then I don’t know.
I’d say about 99% is the same.
Two notable things that were different were:
- Podman config file is different which I needed to edit where containers are stored since I have a dedicated location I want to use
- The preferred method for running Nvidia GPUs in containers is CDI, which imo is much more concise than Docker’s Nvidia GPU device setup.
The second one is also documented on the CUDA Container Toolkit site, and very easy to edit a compose file to use CDI instead.
There’s also some small differences here and there like podman asking for a preferred remote source instead of defaulting to dockerhub.
Oh. This is /technology. I thought pants were about to go way up in price for a second.
Glad I’m not the only one
Dev containers have been dead for a long time.
Docker is not only about dependency management. It also offers service “composing”, via
docker compose
, and network isolation for each service.Although I personally love Nix, and I run NixOS on some of my servers, I do not believe it can replace Docker/Podman. Unless you go the NixOS Containers route.
Interfaces,vlans and capable gateway. Except instead of the vendor lock in you have access to the gold standards of which all out scale
I am trying to understand.
Docker, which uses OCI containers that are supported by Docker, Podman, Containerd, systemd-nspawn, etc, is lock-in.
But Nix Shells, which require Nix, are not lock-in.
Also, how are you going to run Nix shells in VLANs? They run on the host’s network namespace.

Lol. Its the largest and most updated repo of any but by all means, “dozen” hahaha
Are there any decent alternatives to docker hub for pushing images if I’m just a hobbyist?
Github has a container register you can use.
Dunno if it’s decent but I’ve been hosting one service on quay.io since about 2017 and other than that time redhat changed the login system and I had to fart about for a few mins, I’ve never had any issues… Tbh though I probably only update that image about twice a year so I’m not exactly power-user-ing it
Enshitification is a very, very real thing. GitLab did something similar with raising pricing by 5x a few years back.
Oh shit, what would I do without… Scout Analysis?
Don’t you mean SWOT analysis?
You SWOT m8?
sware on me scrum
Recover several hundred GB of disk space, if my team’s experience was any indication.
Hot take: Good for them.
This will have zero impact on 99% of independent developers. Most small companies can move to an alternative or roll their own infrastructure. This will only really impact large corporations. I’m all for corporation-on-corporation violence. Let them fight.
This is a different take on the VMscare broadcom purchase.
The real losers here are SoHos where it is too pricy to migrate and also too pricy not to. I don’t know whether that’s in your 1% or 99% but:
- devs don’t develop for infrastructure their customers don’t use. It’s as dead as LKC, then.
- big customers have deprecated their VMware infra and are only spending on replacement products, and if they do the same for docker the company will suffer in a year.
If docker doesn’t have the gov/mil revenue, are we prepared for the company shedding projects and people as it shrinks?
Remember: when tech elephants fight, it’s we the grass who suffers.
Is this the program that open source people use to install all the random depencies that their program needs to work? The one that people tell me to use when I complain about git bash pico sudo pytorch Install commands?
Or did another company copy their name?
I mean, they’re one implementor of about 10 that use the same container standards. It sucks that they were first so their name is now synonymous with containers a la Kleenex, but the technology itself is standard, very open and ubiquitous, and a huge step forward in simplifying deployments and development lifecycles that would otherwise be too complex to reasonably handle.
To be fair, I used LXC before Docker, so I’ve always called them “containers.” But I guess I’m old or something.
Nope. Docker doesn’t do that. That’s something else.
But it does in a lot of cases. At work, we use Docker images to bundle our dependencies for each microservice, and at home, I use Docker images for the same reason on my self-hosted repos. It’s fantastic for running servers in a sandbox so you don’t have to worry about what dependencies the host has.
But perhaps OP is talking about flatpaks instead.
Not having to install dependencies is a benefit of containers and their images. That’s a pretty big thing to miss. Maybe give it a closer look.
I’m sure “professionals” can afford $4
Our 200 developers all switched from docker desktop to rancher after Docker tried to jack up the price about a year and a half ago, along with a bunch of legal threats. Their attitude was so piss poor, we went from debating paying the higher fees to just fucking them off entirely.
I will pay $4 per user to NOT use Docker.
Hmm, I might have to do that at work. We pay for Docker, but we don’t actually use any of the features from Docker, the service. We build our images locally, and production pulls from AWS ECR, yet we all have Docker Hub licenses because my boss felt like we should be paying for it.
Docker works fine, but honestly, we don’t need it, and I have been considering eliminating Docker on my self-hosted stuff.
I love docker images, hate docker Inc.
Wait…y’all were paying for Docker?
Corp accounts, Docker Desktop isn’t free for non-personal use
That gives me an idea - managers can ask staff to learn the CLI and give them gift cards for what it would have cost to license the Docker Desktop client 🧠
At work we get around this by not having docker or anything similar set up in the first place.
I’m getting tired of it lol
you didn’t need anything like docker with web 1.0; you just needed cuteftp and a text editor.
Me, still using winscp for random nonsense.
Surely you mean WS_FTP LE.
ws_ftp was good but cuteftp supremacy
