Docker container takes forever to extract

Sat Apr 12, 2025 10:38 pm

I'm trying to set up Home Assistant (https://www.home-assistant.io/installation/) using its Docker image (homeassistant/home-assistant:2025.4.2).
I use `docker save` and then I send the file (2GB) to Mikrotik over WiFi (at ~40-50MB/s), and try to run a container on Mikrotik from it.

The problem is it takes 30+ minutes for Mikrotik to extract the container. Any ways around this?

Actually this might be related to RouterOS v19.beta.8.
Things were fine on .7.

It looks like extraction has gotten 8-16 times slower for some reason. There is a chance but i don't think I've changed anything that can make this regression happen.

Things are still not fast but the extra-slowness was related to the USB 3.2 I'm using. Not sure if something was up with Mikrotik or the USB went broken after some time for some reason, but a format fixed the slowness. Will report if I find out anything else.

Ok while I was writing the last message, the whole deployment of the home assistant container finished already. Took only 5mins 20s to upload the 2GB file at ~28MB/s over WiFi, plus extract and run it. 5-6 minutes of downtime is something I can live with.

Before it would actually take around an hour more or less. I did mention "30 minutes or more" before but i hadn't actually tried to keep track of the time it took at that time.
