In my computer I have been manually installed the docker and also docker desktop. I know now there are two docker engines running in my computer. My question is " When I start docker desktop my default engine is changed. How to switch between this docker desktop engine and my previous engine? "
Use
docker context use default
and
docker context use desktop-linux
Note that you will still use the same docker client. If the versions of your docker in Docker Desktop and Docker CE are different, that can also cause problems, but it will probably not
You will also have the same docker client config, which means if your Docker CE is not prepared to use the credential store, you can have problem with docker login.
