uninstall docker toolbox for win

docker toolbox setting

1) make junction (directory hard link) for "Program Files", it will make easy to find VirtualBox tools
from cmd.exe

mklink /j  C:\Program_Files  "C:\Program Files"
Junction created for C:\Program_Files > C:\Program Files
mklink /j  C:\Program_Files_x86 "C:\Program Files (x86)"
Junction created for C:\Program_Files_x86 > C:\Program Files (x86)

2) place VirtualBox path in customized msys2 profile portabledevops.sh under /etc/profile.d/

The default docker home is based on $USERPROFILE, it is $USERPROFILE\.docker, full path like C:\Users\$USERNAME\.docker, I prefer change to msys local home: /home//.docker.

Here is setting lines for msys docker in portabledevops.sh:

if [ ! -d /home/$USERNAME ]; then
	echo "First time to run bash, create home folder: /home/$USERNAME"
	mkdir -p /home/$USERNAME
fi 

export HOME=/home/$USERNAME

export USERPROFILE=$HOME
export HOMEPATH=$HOME

cd $HOME

export HOMEDRIVEL=$(cygpath -m $(pwd) |cut -d: -f1)
export HOMEDRIVE=$HOMEDRIVEL:

# portable docker toolbox for msys
export VBOX_MSI_INSTALL_PATH=/cygdrive/c/Program_Files/Oracle/VirtualBox/
export PATH=$VBOX_MSI_INSTALL_PATH:$PATH
alias dm=/usr/local/bin/docker-machine.exe
alias dc=/usr/local/bin/docker-compose.exe
denv(){
	eval $(docker-machine env "$@")
}
export -f denv

docker test

1) create new docker machine

$ dm create --driver virtualbox --virtualbox-hostonly-cidr "10.0.10.1/24" msysdemo 
$ dm start msysdemo

2) setup env for docker client access

$ denv msysdemo

denv only supports one machine, 0 or 2+ will get error as below:

$ denv
Error: No machine name(s) specified and no "default" machine exists.

$ denv a b
Error: Expected one machine name as an argument

3) docker client test

$ docker ps -a
$ docker info 
$ docker run -it hello-world

4) ssh to docker vm

$ dm ssh msysdemo
