This image is a simple web server application, which can show the host name, ip addresses, environment variables and file system of the container it is run in.

The web server listens on port 8080 by default. The number can be changed using an environment variable called PORT_NUMBER.

How to Use

Create a container using:

docker container run -d -e PORT_NUMBER=8070 -p 8070:8070 rajchaudhuri/inside-container-sample

Then, access http://localhost:8070 to see the container’s hostname and IP addresses. Access http://localhost:8070/env to see its environment variables, and http://localhost:8070/files to see the file system.

If you want to explore a particular path, say /proc, append that to the request like this: http://localhost:8070/files/proc. By default, the web server traverses subdirectories one level deep. You can go deeper by providing a query parameter called depth, like so: http://localhost:8070/files/proc?depth=3.
