terraform-openshift3-ibmcloud-vpc-example

End to end example of deploying Openshift 3 on IBM Cloud VPC. In this example we use the following sub-modules:

• terraform-openshift3-infra-ibmcloud-vpc - To create VMs on VMware.
• terraform-openshift-rhnregister - To register all VMs with Red Hat Network subscriptions.
• terraform-dns-etc-hosts - To hack DNS which we didn't have readily available, we generated an /etc/hosts file containing every node in the cluster and sync it to all nodes.
• terraform-certs-letsencrypt-dns01 - To generate certs from letsencrypt using DNS01 challenge.
• terraform-openshift3-deploy - To generate the ansible inventory file and deploy Openshift.

Before deploying, you will need to set the following environment variables:

export IC_API_KEY

export TF_VAR_rhn_username=<redhat username>
export TF_VAR_rhn_password=<redhat password>

export CLOUDFLARE_TOKEN=<cloudflare token>
export CLOUDFLARE_EMAIL=<cloudflare email>

Use the following commands to deploy:

terraform init
terraform apply 

Example

Example terraform.tfvars file. We provision an non-HA Openshift cluster.

# MUST consist of only lower case alphanumeric characters and '-'
deployment = "ocp-test"

# it's best to use a service account for these
image_registry_username = "<service_acct_username>"
image_registry_password = "<service_acct_token>"

rhn_poolid = "<poolid>"

# to stand up the registry a vssphere block volume
storage_class = "glusterfs" 

# manually added to DNS, the app_cname is a wildcard domain pointing at the infra node
master_cname = "ocp-master.my-private-domain.local"
app_cname = "ocp-app.my-private-domain.local"
