Create VCN and Deploy PBS Pro Cluster

This example shows how to deploy the PBS cluster (open source version) on the Oracle Cloud Infrastructure using Terraform.. This configuration generally implements this:

It creates a VCN with two route tables, Internet Gateway, NAT Gateway, Security Lists, a bastion subnet, and a private subnet for the PBS Pro cluster.

Using this example

• Copy terraform.tfvars.template to terraform.tfvars and update terraform.tfvars with the required information
  • To generate SSH key pair:

  ssh-keygen -b 2048 -t rsa

• Update variables.tf with your instance options

Files in the configuration

main.tf

Defines the compute resources

network.tf

Defines the networking used in the configuration

outputs.tf

Defines the outputs of the configuration

terraform.tfvars.template

Defines the environmental variables used in the configuration

variables.tf

Defines the variables used in the configuration

Run Terraform

Initialize Terraform:

$ terraform init

View what Terraform plans do before actually doing it:

$ terraform plan

Use Terraform to Provision resources and PBS Pro cluster:

$ terraform apply

To connect and test the PBS cluster

Connect to the server using the sample SSH command from the outputs:

$ ssh -i ${ssh_private_key} -Ao ProxyCommand="ssh -i ${bastion_private_key} -W %h:%p opc@${bastion_public_ip}" opc@${server_private_ip}

Check the status of the server:

sudo systemctl status pbs
$ qstat -Bf

Check the execution nodes in the cluster:

$ pbsnodes -a

Run a simple python script:

$ touch myjob.py
$ vim myjob.py
$ cat myjob.py
#!/usr/bin/python
#PBS -l select=1:ncpus=1:mem=1gb
#PBS -N HelloJob
print "Hello"
$ qsub myjob.py
0.pbspro-server

Check the result of the job:

$ ls
HelloJob.e0  HelloJob.o0 myjob.py
