These are real problems with docker, but do we wanna talk about docker for Mac? A total performance disaster. https://github.com/docker/for-mac/issues?q=is%3Aissue+is%3Ao...

I just recently switched to using vscode with the remote ssh plugin and setup an ubuntu vm on my windows machine and performance is like 100x better.

Docker for mac is basically dead to me now, going to finish migrating my projects over to the VM and uninstall it from my laptop.

For all of it's slowness, and constantly filling my hard drive with old builds because that's the workflow for some reason, it solves the real problem of MacOS constantly breaking packages. That alone makes it worth it.

I just want to be able to save a container binary to a USB drive and then run it from a different computer without having to install anything.

You're looking for binctr: https://github.com/genuinetools/binctr

Have you heard of this amazing thing called "a VM"? It is like docker but when you pee at the wall it always splashes back right at you so you quickly learn that you never want to pee at the wall.

All I want is a process that can be frozen and copied to multiple servers. start/stop is merely a state change.

This is interesting... May I ask why this is an important feature to you?

If you think about it most "Service", web or rpc, can be scaled in this way.

I have that problem too. Solution seemed to be to set up an alias to clean out old images, volumes, etc and run that every so often

Not just in MacOS. Over time, Docker can eat all your storage.

Because it keeps around all of the images you use as well as the containers after they are stopped so you can resume them. there is a command that auto automatically removes all unused images and containers you can use.

I have no idea how, but Docker for Mac was taking up a whopping 65GB of space in one of the cache folders in ~/Library, although I had uninstalled it months ago. I wish I had taken a screenshot, but I was honestly dumbfounded. I had used it maybe once, ever. EDIT: It turns out I’m not making this up/an edge case, at least 940 people have run into this too: https://github.com/docker/for-mac/issues/371

The issue linked is that is doesn't actually reclaim the space - you either have to wipe it out or do that workaround mentioned to resize it manually.

Have you tried running the Vscode + Linux Subsystem + Docker on Windows stack? It's been pretty good so far (a good writeup on this is at https://nickjanetakis.com/blog/setting-up-docker-for-windows...)

those scripts are now built into docker with `docker system prune`

Yeah. I have to run docker system prune from time to time.
