CPU usage 200%+ High heat on WEB docker build on Mac

[federicosan]

• [x ] I have tried with the latest version of my channel (Stable or Edge)
• [x ] I have uploaded Diagnostics
• Diagnostics ID: 58211D3E-4E1B-4CED-BC26-666B2D315EA2/20200326195749

Expected behavior

No heat, reasonable CPU usage.

Actual behavior

Heat so high, docker needs to be shut down to prevent the device hazard

Diagnostic logs

Docker for Mac: version...

Docker version 19.03.8, build afacb8b
docker-compose version 1.25.4, build 8d51620a
I posted this to docker's repo first, I am copying here if someone already knows how to fix this. I could not build the site because of fear of hazard heat was insane, 300% CPU usage at times.

Steps to reproduce the behavior

1. ... install gitcoin.co/web repo on https://docs.gitcoin.co/mk_setup/
2. ... follow the instructions

hmmm interesting.. im on an 8 core macbook, and the docker container builds ok for me. is your laptop in a well ventilated place? im pretty sure theres no fire hazard running at full cpu for most well maintained machienes

i wonder what would happen if you only ran web_web and web_db

It seems mac and docker have some issues, I first posted to docker's repo and there many many issues and very similar regarding this. My mac has only 4 cores, those are the specs. I already tried setting debug to false. I don't know what else to do, CPU usage goes to 300, with an average +200 and it heats as it is launching to mars.

Can second have had issues with mac and docker before. Ill try to build when im back at my desktop. Hopefully we can get to the bottom of this.

Updates

Changing resources from 4 cores to 2 cores and setting disk image size to only 8 GB.
makes CPU usage stay between 40% and 220%, with a >100% CPU most (90%) of the time but at least not near 300%. Will try lowering resource to only 1 core and see what happens.

Heat also went down and finished the build but after it finished docker went full 200% and heat started raising like if hell was set loose, had to force quit docker. I let it run so I am thinking this is the problem: the docker resources. I am really new to docker and had used it only in really small projects using vagrant instead most of the time, I don't know if there were some docker special configurations for this not to be happening, I will keep trying after mac cools down.

More updates

Setting cores to 1, takes CPU usage to 30% - 40% this is still high but it makes it usable and the mac is not heating as it was to explode. I am not sure but I don't think not using resources is a solution, docker should be able to use what it needs and not all resources. Is building that intensive?

I think this all should be added as a troubleshooting tip to the installation guide, what do you think?

[owocki]

yeah thats a good idea
