I've never been able to run Docker on my MacBook Pro without the CPU's going crazy and the energy usage skyrocketing. I opened a ticket about it, but there have been other related tickets that have been closed without any real resolution: https://github.com/docker/for-mac/issues/4323

It unfortunately prevents me from using Docker for local development. I'm hoping things change with M1.

Similarly, I installed docker-machine and docker (via Homebrew) on my M1 mac via Rosetta 2, and connect to a remote docker host, similar in configuration to this blog post (which really has a misleading title).

That works - but it pegs processor usage on the M1 mac...

What is the performance like though?

speed is just dependent upon the speed of the remote docker instance... and latency...

for me - perf is great.

Clarifying - I think my 'processor usage' issue is from running lazydocker (and exiting). Not sure what the issue is.

Docker on mac is a vm, and things relating to volume mounts are horrendous. Switched to a linux laptop (aero15) and things work now.

yeah osxfs, their solution for syncing mounted file paths, has a massive performance hit. the less files you need to mount in your composes the better. http://docker-sync.io/ helps, but docker for mac is still slow.

Why do people always try to create a local environment that would be quite different from the production environment?

Run a real Linux under VMware fusion or rent a remote $5 Linux and set up Docker and other stuff there.

Cause it's good enough, and we have ci servers and qa environments.

Simplicity is king in local dev.

I notice that it consistently uses about 10% of a CPU while idle. I searched for this issue on github and see people complaining about it as far back as 2017, so I know it's probably not going to be addressed anytime soon.
