This repository will spin up an environment to conduct a Monaco HOT session based on VMs running in GCP.

Contents

The following will be deployed:

• An Ubuntu VM in GCP with a public IP address
• Monaco
• k3s
• Helm
• Gitea
• Jenkins
• Dynatrace OneAgent
• Dynatrace ActiveGate for private synthetic
• An application in 3 namespaces
• A launchpad dashboard

Using Terraform to spin up the HOT environments

At the moment, only GCP is supported with a ready-made Terraform config.

Requirements

Terraform needs to be locally installed. A GCP account is needed.

Instructions

1. Prepare Service Account and download JSON key credentials in GCP.

   https://cloud.google.com/iam/docs/creating-managing-service-accounts

2. Initialize terraform

   terraform init

3. Create a terraform.tfvars file inside the terraform/gcloud folder It needs to contain the following as a minimum:

   name_prefix          = "example-vhot-monaco"
   dt_cluster_url       = "https://{id}.managed-sprint.dynalabs.io" 
   dt_cluster_api_token = "{your_cluser_api_token}"
   gcloud_project       = "myGCPProject" # GCP Project you want to use
   gcloud_zone          = "us-central1-a" # GCP zone name
   gcloud_cred_file     = "/location/to/sakey.json" # location of the Service Account JSON created earlier
   users = {
     0 = {
       email = "user1@example.com"
       firstName = "John"
       lastName = "Smith"
     }
     1 = {
       email = "user2@example.com"
       firstName = "James"
       lastName = "Miner"
     }
   }

   Check out variables.tf for a complete list of variables

4. Verify the configuration by running terraform plan

   terraform plan

5. Apply the configuration

   terraform apply

6. All resouces can be destroyed with this command:

   terraform apply -var="environment_state=DISABLED" -target=dynatrace_environment.vhot_env -auto-approve && terraform destroy

Using the environment

After provisioning, terraform will give the output of all the public ip addresses. You can log in with ssh using ace as username and password. A dashboard gets created that can be accessed via a browser on http://dashboard.VM_IP.nip.io which has links to jenkins and gitea
