Now we have everything prepared in that folder.
Build and run the Docker container
- In your Terminal window, navigate to the "odysseusdocker"-folder
- Type "sudo docker build ." (The " ." refers to the folder we are in. The command assumes a file named "Dockerfile" in that folder.)
- Wait (it will take some time to get the basis for our container: Ubuntu and Java 8)
- Now we should see a message that the container was successfully build. We can type "sudo docker images" to see our images.
