Deploy "Todo" app provided by Docker to one virtual machine (CentOS Linux 7) with Ansible.

I used two virtual machines , the main one is a Kali linux machine where I made the deployment of application into the CentOS machine.

Here, I used two diffrent files : iventory and playbook.

The iventory file where I stored the IP_Addr of the host(192.168.50.141) , the port(22 for ssh) and credentials for a successful login. The ansible playbook file is getting-started_deploy.yaml where I had to put the task of copying all the files from the local path location to the remote server so I done the deploy.

For the task to be accomplished I used a single command : "$ ansible-playbook -i inventory getting-started_deploy.yaml" where I specified the inventory for remote connection within parameter '-i inventory' and the plays with the playbook file 'getting-started_deploy.yaml'.

After the command succesfully ran the screen should look like this:

On the remote server, the file appeared at the path specified in playbook which is /home , cd(change directory) into the /home/getting-started/app where I built the app with "# docker built -t getting-started . " and then I ran the app with "# docker run -dp 3000:3000 getting-started". The application works as expected, but I need to add a database(because I don't want the changes to be removed when the container is restarted) into it so I have to add a volume with "# docker volume create todo-db" I delete the old docker container with "# docker rm -f" and then I ran again the app but with the specified db volume "# docker run -dp 3000:3000 -v todo-db:/etc/todos getting-started".

For the application to be seen check the following link: https://ec1933bf4045ea.lhr.domains

Legend:

• '$' sign is used on kali machine as normal user(kali)
• '#' sign is used on remote machine(CentOS) as root user
• /etc/todos is path location where SQLite stores its data in container's filesystem
