scripting - How can a script distinguish Docker Toolbox and Docker for Windows? -

on current team, we're still transitioning docker toolbox docker windows. lot of our scripts still assume you're running docker toolbox on virtualbox (like how mount drives, how slashes or drive names work mounts).

is there reliable way tell, inside script, whether docker coming docker toolbox or docker windows?

toolbox works via docker-machine. way docker client directed virtual machine via number of environment variables can see running docker-machine env default

set docker_tls_verify=1 set docker_host=tcp://192.168.99.100:2376 set docker_cert_path=/user/.docker/machine/machines/default set docker_machine_name=default rem run command configure shell:  rem     @for /f "tokens=*" %i in ('docker-machine env --shell cmd default') @%i 

docker mac connects directly /var/run/docker.sock socket mapped docker vm easy detect lack of environment variables.

i believe docker windows uses named pipe in same way (//./pipe/docker_engine) should able tell lack of docker_host in environment.

if docker windows still use environment, there differences between toolbox , docker windows variables. docker_host on different range. docker_cert_path won't include machine etc.
