Docker Toolbox

Docker login error

Error: error getting credentials - err: exec: "docker-credential-osxkeychain": executable file not found in $PATH, out:

Speed up Docker in MacOS

1. Install docker machine NFS: brew install docker-machine-nfs (https://github.com/adlogix/docker-machine-nfs)

2. Restart your computer

3. Mount in your docker VM (e.g. default): docker-machine-nfs default --mount-opts="nolock,vers=3,tcp,fsc,rw,noatime"

If you receive the "Cannot detected the NFS mount :(" error, then do the following:

"default" is the docker machine name.

1. docker-machine regenerate-certs default
2. docker-machine-nfs default
3. docker-machine-nfs default --mount-opts="nolock,vers=3,tcp,fsc,rw,noatime"

Test Docker speed (you should expect < 1 sec results)

docker run -it -v /Users/youruser/test:/var/www alpine time dd if=/dev/zero of=/var/www/test.dat bs=1024 count=100000
