Exposing a Container Port on the Host
Tested Infrastructure
| Platform | Number of Instance | Reading Time |
|---|---|---|
| Mac OS | 1 | 5 min |
Pre-requisite
- A linux system (here we have used macbook)
- Docker installed
To expose the container port on the host we use -p or –publish option. [-p host_port:container_port ]
$ docker run -dit --name my-apache-app -p 8080:80 -v "$PWD":/usr/local/apache2/htdocs/ httpd:2.4

Once the port exposed to host , try to reach the port via explorer or with curl commands. You should get proper output from the container
$ curl localhost:8080
