• Visit http://localhost:3500/users from your docker host machine.

2. Installation in Physical machine/VM to manage itself.

  export GOPATH=/home/vic/code/golang/workspace

  export PATH=$PATH:$GOROOT/bin:$GOPATH/bin

• Download go and put it in GOROOT directory

  Install Golang

• Clone the application's repository from github inside $GOPATH/src/github.com/alok87

  go install
  
  cd $GOPATH/src/github.com/alok87/sysAdmin
  
  main --addr ':3600'        // You should specify ports below 4999
