LAUNCH APACHE WEBSERVER INSIDE DOCKER CONTAINER USING ANSIBLE
TASK DESCRIPTION:
Using Ansible Playbook We Will Configured docker and start the apache services.
👉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 files and start the web server.
Rough Overview What We Are Going To Do:
step 1: Create a docker yum repository.
step2: Install docker by using yum command.
step3: Create a workspace on target node where our code will be copied by managed node
step4: Start the docker services
step5: Pull the httpd image(because by pulling httpd image it will done our half work automatically like starting apache services inside the docker).
step6: Launch docker container and expose it to the port number(you can choose any port number of your choice).
Requirement:
✔One Managed Node
✔One Target Node
📍In this practical managed node and target node both are configured on local os(RHEL8)
CREATE AN ANSIBLE PLAYBOOK WHILE CONSIDERING THE ABOVE STEPS
Create an inventory which includes IP address of Target node and also update the configuration file of ansible playbook
vim /root/ip.txt
Always check the ansible connectivity to confirm nodes connectivity.
ansible all -m ping
Create a workspace in managed node where you will write all ansible playbook code I have created workspace name ws7 and my playbook name is webserver.yml . In this one index.html file has also been created
FINAL PLAYBOOK CODE

PLAYBOOK OUTPUT
LETS SEE TARGET NODE
As we can see ansiblewebos directory has been created and also index.html page has been created in our target node
Lets run some docker commands in our target node⏩
Check the status of the docker in the target node
systemctl status docker
docker images (to see our httpd image that we pull )
docker ps (to see all running container thaat we launched with the help of docker pull command)
YES APACHE WEBSERVER HAS BEEN SUCCESSFULLY CONFIGURED
Now checked the webpage from the webbrowser using syntax👇
IP(TARGET NODE): PORT NO
