How to start the Web Server in Docker Container using Ansible Playbook?

Description:-

• Configure Docker
• Start and enable docker services.
• Pull the HTTPD server image from the Docker Hub.
• Run the docker container and expose it to the public.
• Copy the HTML code in /var/www/html directory and start the web server.

The ansible playbook for the same is as follows:-

hosts: all
  tasks:
          - name: Create Yum Repo
            yum_repository:
                  name: "docker"
                  description: "this is a docker repo"
                  reposdir: "/etc/yum.repos.d/"
                  baseurl: "https://download.docker.com/linux/centos/7/x86_64/stable/"
                  gpgcheck : "no"
                  enabled: yes- name: Run Yum RepoList
            command: yum repolist- name: Run Docker CMD
            command: yum install -y --nobest docker-ce- name: Check Package
            package:
                  name: "docker-ce"
                  state: present- name: Check Service
            service:
                  name: docker
                  state: started
                  enabled: yes- name: Install Docker SDK
            command: "pip3 install docker-py"- name: Pull IMG From DockerHub
            docker_image:
                    name: "vimal13/apache-webserver-php:v1"
                    source: pull
                    
          - name: Run Container
            docker_container:
                    name: "container1"
                    image: "vimal13/apache-webserver-php:v1"
                    state: started
                    detach: yes
                    exposed_ports:
                            - 80
                    ports:
                            - "8080:80"- name: Initiate HTTPD on Docker
            command: "systemctl start httpd.service"- name: Get Container Details
            docker_container_info:
                    name: "container1"
            register: result- name: Copy File To TN
            copy:
                    src: "demo1.html"
                    dest: "/root"- name: Copy File To Docker Container
            command: "docker cp /root/demo1.html container1:/var/www/html"

Now, run the playbook using the following command:-

ansible-playbook 'playbook_name.yml'

We can also check whether these services are configured in the target node or not. The command for the same is as follows:-

systemctl status docker

To run the container created using playbook, the following command is executed (here the name of my container is “container1”).

docker exec -it container1 bash

Next, find the IP address of the container using the following command:-

ifconfig

Finally, run the following command to see the content inside the HTML file:-

curl 172.17.0.2/demo1.html
