1. Objective
2. View Initial Design and Configuration
3. Complete the Configuration
4. Version the Configuration
5. Run the Configuration
Welcome to the Open Learn LZ Exercise #1.
The main objective is to create, version, and run the IaC configurations for the OCI Learn LZ Tenancy Structure focusing on IaC configurations and not on code, The OCI Landing Zones Orchestrator is a generic Terraform module that orchestrates the creation of Landing Zone architectures expressed in a single or multiple configuration files, that can be JSON documents and YAML documents.
In this example we use YAML configurations files, but JSON files examples are also provided.
In this exercise, you will create the tenancy structure IaC configuration to include the target domains. Your IT Central Team colleagues already started this, your mission is to finish the configuration.
Your objective is to review the initial tenancy structure created by your team, containing part of the channels domain.
| ACTIVITY | DESCRIPTION |
|---|---|
| 1 | Open the Drawio design file, and select tab "SEC - EXERCISE #1" |
| 2 | Enable the Layer "STEP 1 - TEMPLATE". Make sure the STEP 2 layer is disabled. |
| 3 | Review the tenancy structure design that is already created. The image below presents it. |
| 4 | Review configurations. First review what is possible to configure and then review the exercise specific configurations scope. These views are also available on the draw.io tabs. |
| 5 | Copy the configuration file oci_learn_lz_iam.yml to your local OCI-LEARN-LZ-OPS-REPO/oci-open-lz/exercise1. |
| 6 | Review the tenancy structure configuration in you local oci_learn_lz_iam.yml file. |
Your objective is to update the tenancy structure with a missing application core systems domain, and finalize the channels domain.
| ACTIVITY | DESCRIPTION |
|---|---|
| 1 | Open the Drawio design file, and select tab "SEC - EXERCISE #1" |
| 2 | Enable the Layer "STEP 2 - EXERCISE". Make sure the STEP 1 layer is enabled. |
| 3 | Review the target tenancy structure design with the two domains. The image below presents it. |
| 4 | Update the tenancy structure IaC configuration with the new changes in your local oci_learn_lz_iam.yml file. |
Your objective is to update your configurations on the OCI-LEARN-LZ-OPS-REPO git repository.
| ACTIVITY | DESCRIPTION |
|---|---|
| 1 | Push your local changes on the oci_learn_lz_iam.yml to the remote OCI-LEARN-LZ-OPS-REPO/exercise1 folder. The image below is a high-level representations of this. |
Your objective is to run your new configuration with ORM. The image below contains the high-level automation mechanism, which is based on an ORM Stack that is linked to your versioned configuration file(s).
The OCI Landing Zones Orchestrator is a generic Terraform module that orchestrates the creation of Landing Zone architectures expressed in a single or multiple configuration files, that can be JSON documents and YAML documents.
In this example we use YAML configurations files, but JSON files examples are also provided.
| ACTIVITY | DESCRIPTION |
|---|---|
| 1 | Create a new ORM Stack:  |
| 2 | Accept terms, wait for the configuration to load. |
| 3 | Set the working directory to “rms-facade”. |
| 4 | Set the stack name you prefer. |
| 5 | Set the terraform version to 1.5.x. Click Next. |
| 6 | Delete the default configuration link and paste the new git raw link of your oci_learn_lz_iam.yml remote file. NOTE: Don't forget to press enter or click on the "Add" pop-up after pasting. |
| 7 | Un-check run apply. Click Create. |
| 8 | Run Terraform Plan and review the output messages. |
| 9 | Run Terraform Apply and review the created resources, they should match the design diagrams. |
After finalizing this exercise you have now a coherent set of artifacts: a design, a versioned configuration, OCI instantiated resources, and an ORM stack that contains the state file.
You can proceed to Exercise 2.
