Creating Docker Containers running Kofa

With the given Dockerfile and script we can create a docker container running waeup.kofa 1.3.3.

The following are merely notes to self.

Prepare Your Local Ubuntu

Install docker:

$ sudo apt-get install docker.io

On Ubuntu "docker.io" is the official repo name of docker. This is to distiguish from the same-named GUI app.

Pull a recent Ubuntu image from docker repository:

$ docker pull ubuntu:14.04.3

This will fetch some hundred MBs.

You can play a bit with the freshly installed images.

This docker image of waeup.kofa is based on Ubuntu 14.04.3. We have to get the Dockerfile and the build.sh script:

$ git clone https://github.com/waeup/kofa-docker.git

This will put everything into a new local kofa-docker dir. Change to it:

$ cd kofa-docker/

Now start the build:

$ docker build -t kofa .

This will take _lots_ of time, but should run until end.

When finished, you can run you freshly installed instance like this:

$ docker run --net=host -t -i kofa

whch will drop you into a shell on the 'virtual' docker container. Change to waeup.kofa and start the server:

(container) $ cd waeup.kofa
(container) $ ./bin/kofactl fg

After startup you should be able to reach the portal on your local port 8080. Open

http://localhost:8080/

If you stop the container shell (type 'exit'), the container will still exist:

$ docker ps --all

To remove it, run:

$ docker rm <container-name>

with the <container-name> listed before.

To see locally available images, run:

$ docker images

An image can be removed with:

$ docker rmi <image-id>

where <image-id> is a hex number as listed by the command before.

You can also start containers stopped before and reattach to them:

$ docker start <container-name>
$ docker attach <container-name>

will bring you back into the container.
