How do I create a docker image?

[petulia3478]

To create a docker image from a git clone for eample:

$ sudo git clone https://github.com/fabric8io/base-images.git
Cloning into 'base-images'...
remote: Counting objects: 1583, done.
remote: Total 1583 (delta 0), reused 0 (delta 0), pack-reused 1583
Receiving objects: 100% (1583/1583), 212.22 KiB | 0 bytes/s, done.
Resolving deltas: 100% (856/856), done.
Checking connectivity... done.

$ sudo docker build -t local.io/docker-java:latest .      

(There is a dot at the end)
