How to make a port available to services outside of Docker

Question

Hi Guys,

I have my docker containers in my virtual machine, but I want to connect to my containers outside of my VM. How can I do that?

Hi@akhtar,

By default docker containers works in a isolated network. But if you want to connect to your container outside from host machine, you have to expose your container. Means you have to apply NAT/PAT concept to do this task. When you run your command to launch  container, you have to use -p flag like -p 8080:80.
