Write a Docker Compose File

Task :

The Nautilus application development team shared static website content that needs to be hosted on the httpd web server using a containerized platform. The team has shared details with the DevOps team, and we need to set up an environment according to those guidelines. Below are the details:

a. On App Server 3 in Stratos DC create a container named httpd using a docker compose file /opt/docker/docker-compose.yml (please use the exact name for file).

b. Use httpd (preferably latest tag) image for container and make sure container is named as httpd; you can use any name for service.

c. Map 80 number port of container with port 8088 of docker host.

d. Map container’s /usr/local/apache2/htdocs volume with /opt/security volume of docker host which is already there. (please do not modify any data within these locations).

Solution :

thor@jump_host /$ ssh banner@stapp03

We trust you have received the usual lecture from the local System
Administrator. It usually boils down to these three things:

#1) Respect the privacy of others.
#2) Think before you type.
#3) With great power comes great responsibility.
