Docker: How to build you own container with your own application

atThere are many tutorials out there, how to create a docker container with a apache webserver inside or a nginx.
But you can hardly find a manual how to build your own docker container without pulling everything from a foreign repository.
Why should you not pull everything from foreign repositories?

You should read this article or this:
But since each phase of the development pipeline is built at a different time, …
…you can’t be sure that the same version of each dependency in the development version also got into your production version.
That is a good point.

As considered in this article you can put some more constraints into your docker file: 
FROM ubuntu:14.04.
or even
FROM ubuntu:0bf3461984f2fb18d237995e81faa657aff260a52a795367e6725f0617f7a56c
And that is the point where i tell you: Create a process to build your own docker containers from scratch and distribute them with your own repository or copy them to all your docker nodes (s. here)

So here the steps to create your own container from a local directory (here ncweb):

# ls -l ncweb/
total 12
-rw-r--r--    1 root     root            90 Nov 26 10:06 Dockerfile
-rw-r--r--    1 root     root           255 Nov 26 11:29 index.html
-rw-r--r--    1 root     root             0 Nov 26 11:29 logfile
-rwxr--r--    1 root     root           176 Nov 26 11:29 ncweb.sh  
The Dockerfile contains the following:

# ls -l ncweb/
alpine:~# cat ncweb/Dockerfile 
FROM alpine
RUN mkdir ncweb
ADD .  /tmp
ENTRYPOINT [ "/tmp/ncweb.sh" ]
Into this directory you have to put everything you need, e.g. a complete JDK or your binaries or ...

And then change into this directory and build your container:

ncweb# docker build -t ncweb:0.2 .
The distribution to other docker nodes can be done like this:

# docker save ncweb:0.3 | ssh docker load
