challenge-2

Challenge 2

In this challenge we will implement a simple LAMP stack using terraform and docker.

Utilize /root/code/terraform-challenges/challenge2 directory to store your Terraform configuration files.

We will create the resources in the order of their dependencies, thus you may run plan/apply at any stage, or wait till the end.

Note that these challenges do not use an embedded VSCode IDE, therefore we must use the venerable vi to create and edit files. Now you can put all the resources into a single file e.g. main.tf or as shown here in separate files. Terraform doesn't care!

1. terraform-jump-host
   Install terraform binary version=1.1.5 on iac-server

   curl -L -o /tmp/terraform_1.1.5_linux_amd64.zip https://releases.hashicorp.com/terraform/1.1.5/terraform_1.1.5_linux_amd64.zip
   unzip -d /usr/local/bin /tmp/terraform_1.1.5_linux_amd64.zip

2. docker
   Docker provider has already been configured using kreuzwerker/docker provider.
   Check out the provider.tf given at /root/code/terraform-challenges/challenge2

   cd /root/code/terraform-challenges/challenge2
   cat provider.tf

   Let's initialize the provider now.

   terraform init
   

   You should now refer to the documentation for this provider. Go to the Terraform Registry and paste kreuzwerker/docker into the search bar.

3. php-httpd-image
   Create a terraform resource named php-httpd-image

   Refer to the provider documentation for docker-image

   Using vi, create php-httpd-image.tf

4. mariadb-custom-image
   Create a terraform resource named mariadb-image

   Refer to the provider documentation for docker-image

   Using vi, create mariadb-custom-image.tf

5. mariadb-volume
   Create a terraform resource named mariadb_volume

   Refer to the provider documentation for docker-volume

   Using vi, create mariadb-volume.tf

6. private_network
   Create a terraform resource named private_network

   Refer to the provider documentation for docker-network

   Using vi, create private-network.tf

7. db
   Define a terraform resource mariadb for creating docker container

   Refer to the provider documentation for docker-container

   Using vi, create db.tf

8. webserver
   Define a terraform resource php-httpd for creating docker container

   Refer to the provider documentation for docker-container

   Using vi, create webserver.tf

9. db_dashboard
   Define a terraform resource phpmyadmin for docker container

   Refer to the provider documentation for docker-container

   Using vi, create db-dashboard.tf

10. DEPLOY!

    terraform plan
    terraform apply
