Ansible Container Workshop

Agenda:

1. Running default python http server in a container.
2. ansible/ansible-container-demo

"Hello World" project

The most important link.

Install it

$ pip2 install --user ansible-container[docker]

Ehm, what does the project look like?

We'll do

$ python3 -m http.server 9000

in a container

$ docker run --rm fedora:27 python3 -m http.server 9000

Workspace

We'll spend the whole time inside directory hello. That's our project.

$ mkdir hello && cd hello

container.yml

$ cat container.yml
settings:
  conductor:
    base: 'fedora:26'

services:
  web:
    from: 'fedora:26'
    command: ['python3', '-m', 'http.server', '--bind', '0.0.0.0', '9000']

Let's build it and run it:

$ ansible-container build
$ ansible-container run

What's next?

• Expose port to host:

  ports: ["9000:9000"]
  

• Enable selecting the dir to serve:

  defaults:
    workdir: "/etc"
  

      working_dir: '{{ workdir }}'
  

• I also want to put my files in.

  • For that, we need add an Ansible role which will copy them.

Orchestrated

Find registry inside openshift deployment:

$ oc login -u system:admin

$ oc get svc --all-namespaces
NAMESPACE   NAME              CLUSTER-IP     EXTERNAL-IP   PORT(S)                   AGE
default     docker-registry   172.30.1.1     <none>        5000/TCP                  13m

$ oc login

$ docker login -u $(oc whoami) -p $(oc whoami -t) 172.30.1.1:5000
