I had sync delays of about 15 seconds, when I changed a file on my MacOS fs and that it was seen as changed inside the docker container. This solved it: colima start --mount-type 9p

I learned just yesterday that Docker Inc. is charging for their Docker Desktop client. Only when certain conditions apply, but still. I am not at all against charging for good products, but now I also understand why the docker app and website wanted me to log in lately. Good time to get rid of it and use the less annoying tools, I found colima as my new docker runtime, simple, easy, not in my way.

For a while vagrant was cool.

I just watched the very good, How to run Nginx inside Docker container video. In 9 minutes you will learn the basics of docker while starting up an nginx server running on docker. The real take away for me is the updated docker commands, which are finally as explicit as I always had wished they had been from the beginning. Like docker container run which was docker run.
