Hello World

In this exercise you should create a new Dockerfile that starts a bash script and then exits. The script is already provided to you (see the script.sh)

Here are the different steps:

• use alpine:latest as base
• set the workdir to /
• install bash
• copy the script.sh into the container
• set the permissions on the shell script to 755
• set the CMD directive to run the script at start

Build an image and run a container in foreground and check that "Hello World" get's printed.

Bonus

Try to find a faster way to print "Hello World" with a container without building your own Dockerfile.

Solution

See the working Dockerfile and here for the commands to build and run in.
