How do I undo the command $ eval “$(docker-machine env blog)”

Question

I think that command redirected $ docker commands to the docker machine. Now all my docker commands are giving me an error FATA[0000] Couldn\'t read ca cert.

Answer 1

All you have to do is run

docker-machine env machine-name

Then, copy and run the last segment in the output to set or remove the env variables.

Which looks like this in Windows :

eval $("C:\Program Files\Docker Toolbox\docker-machine.exe" env machine-name)

If it's set already, docker adds a "-u" at the tail to make the task easy.

like this in Windows :

eval $("C:\Program Files\Docker Toolbox\docker-machine.exe" env -u)

That's all.
