Docker is helpful in a lot of ways.
Today, after dockerizing an application's services into different containers, I ran into situation where I need to make changes to the code of one of the container that serves API.
Well, docker dev mode is not really a thing/command that available out of the box.
Though there are different ways to do it, I eventually did it with
volumes: - /Users/yourDir/yourAwesomeApp:/var/www/yourAwesomeApp
It is a concept of docker which let you
mount a host to your container.
Any changes you made to your host machine will be reflected in the container, without the need to stop and compose the services again.
I will be sure to explore this topic deeper in the future.
