The Nautilus Application development team recently finished development of one of the apps that they want to deploy on a containerized platform. The Nautilus Application development and DevOps teams met to discuss some of the basic pre-requisites and requirements to complete the deployment. The team wants to test the deployment on one of the app servers before going live and set up a complete containerized stack using a docker compose fie. Below are the details of the task:

  1. On App Server 1 in Stratos Datacenter create a docker compose file /opt/finance/docker-compose.yml (should be named exactly)/
  2. The compose should deploy two services (web and DB), and each service should deploy a container as per details below:
  3. For Web Services:
    a. Container name must be php_apache.
    b. Use image php with any apache tag. Check here for more details.
    c. Map php_apache container's port 80 with host port 5001
    d. Map php_apache container's /var/www/html volume with host volume /var/www/html.
  4. For DB Services:
    a. Container name must be mysql_apache.
    b. Use image mariadb with any tag (preferably latest). Check here for more details.
    c. Map mysql_apache container's port 3306 with host port 3306
    d. Map mysql_apache container's /var/lib/mysql volume with host volume /var/lib/mysql.
    e. Set MYSQL_DATABASE=database_apache and use any custom user ( except root ) with some complex password for DB connections.
  5. After running docker-compose up you can access the app with curl command curl <server-ip or hostname>:5001/
ssh in as normal
cd /opt/finance
sudo vi docker-compose.yml
