In this blog, we will just add a new prod cluster. Except some very few changes, this is pretty simple to do.
A new cluster is created for our prod
Lets conect to ansible and just copy all files from dev and place into prod , we dont need the terraform.tfstate terraform.tfstate.backup tfplan as they belong to the dev so it looks like this now.
Make changes to data.file..
- Name change – Cluster 01 to Cluster 02
- Datastore cluster name – Change to Prod-DataStore Cluster
Under main.tf, change from prod to dev
Under the organise.tf file, this is where we have one chnage .. It tries to create the “Environment” tag category again. Dev already created it, and vCenter allows only one category with that name, so prod’s apply would fail with “already exists”. In prod it must be a lookup (data), not a resource so it should like
We can remove the above and replace with as shown
Nothing to change in providers.tf file
Under variables, we change the folder to Terraform-Prod and this is the default folder were all VM’s land initially.
Under the teraform.tfvars we also are going to add these new VM’s for our prod
Ok, let’s create the new Prod cluster
Apply the plan
First run this command to check-in our vCenter credentials
awk@ansible:/etc/ansible/terraform$ source env.sh
Password
Now, navigate to prod directory and run terraform init – this downloads the vSphere plugin
terraform init
terraform plan -out=tfplan shows what Terraform is about to do and it says 3 VM’s are going to be deploye d
Run terraform apply tfplan to deploy the VM
After few minutes, the VM are live in Cluster 02
All VM’s in prod land in
ansible -i “172.16.19.160,” all -m ping to check if The VM is reachable
Once everything is running smoothly git it.
