Pack ansible in docker

Write Dockerfile

This module is to write Dockerfile, push to Gitlab, write Gitlab CI job to build a container from the Dockerfile & upload to Gitlab Container registry.

Step 1: Dockerfile (do not use - because of issues with Ansible collection backend)

FROM alpine:latest
RUN apk add py3-pip \
build-base \
python3-dev \
libssh-dev \
ansible \
openssh-client

RUN pip install ansible-pylibssh
RUN apk --no-cache add ca-certificates \
  && update-ca-certificates 
RUN ansible-galaxy collection install vyos.vyos
ADD ansible.cfg /etc/ansible/ansible.cfg

Step 2: Push Dockerfile on Gitlab

Step 3: Write .gitlab-ci.yml for Docker building

stages:
  - Docker build

Build Container:
  image: docker:latest
  stage: Docker build
  services:
    - docker:dind

  variables:
    DOCKER_HOST: tcp://docker:2375/
    DOCKER_DRIVER: overlay2
    DOCKER_TLS_CERTDIR: ""

  before_script:
    - docker login -u "$CI_REGISTRY_USER" -p "$CI_REGISTRY_PASSWORD" $CI_REGISTRY
  script:
    - docker build --pull -t "$CI_REGISTRY_IMAGE:latest" .
    - docker push "$CI_REGISTRY_IMAGE:latest"
  when: manual

Step4: Trigger job & ensure the container is built
