Ansible inside a Docker and configure other containers

Docker image build commands:

docker build -t apache-php --no-cache=true ./apache docker build -t nginx --no-cache=true ./nginx docker build -t ansible --no-cache=true ./ansible

Commands to build container:

docker run -d --name testapachephp2 -p 80:80 -v /home/ubuntu/nginx/samplekey.pub:/root/.ssh/authorized_keys apache-php /bin/bash docker run -d --name testnginx -p 8080:80 -v /home/ubuntu/nginx/samplekey.pub:/root/.ssh/authorized_keys nginx docker run --privileged -d
--link testnginx
--volume=/home/ubuntu/nginx/samplekey:/root/.ssh/samplekey
--volume=/home/ubuntu/nginx/samplekey.pub:/root/.ssh/samplekey.pub
--volume="$(pwd)/files":/etc/ansible/roles/role_under_test:ro
--name ansible-test
centos7-ansible /sbin/init

[ Before Creating the containers, create ssh key in host machine and use that key in ansible. Use the same as authorized key in other containers ]

After launch of containers, get inside ansible container and add the 'testnginx' in /etc/ansible/hosts. To enter inside container, docker exec -i -t ansible-test bash

Once done, run below command to execute the playbooks, sudo docker exec -t ansible-test ansible-playbook /etc/ansible/roles/role_under_test/site.yml
