Terraform deployment of LocalEGA on openstack

Deploy LocalEGA on Openstack using Terraform

Preliminaries

You need to prepare a file with your cloud credentials and source it.

Have a look at credentials.rc.sample and "fill in the blanks."

The file contains the Openstack configuration along with a few variable for Terraform.

Create a fake Central EGA

cd cega
./bootstrap.sh swe1 fin1   # List of space separated instances
terraform init
terraform apply

Create an instance of Local EGA

Move back to the main directory for Terraform (ie cd ..). The following creates one instance of Local EGA.

bootstrap/run.sh
terraform init
terraform apply

That's it. Wait for Terraform to contact your cloud and create the resources.

Services are started, and Volumes are mounted, using Systemd units.

Demo

Stopping

cd cega
terraform destroy
cd ..
terraform destroy

Type yes for confirmation (or use the --force flag)

Build the EGA-common, EGA-db and EGA-mq images

cd images/centos7
terraform init
terraform apply

The booted VMs use a CentOS7 Cloud image and are configured with cloud-init. Once configured, they are powered off.

You can then take a snapshot of them and call them 'EGA-common', 'EGA-db', 'EGA-mq' and 'EGA-cega'.

Troubleshooting

Comment out line 50 in case you have errors, to inspect them. In my case, I noticed the openssl version on my mac was old. So I use:

$ bootstrap/run.sh --openssl /usr/local/Cellar/openssl/1.0.2n/bin/openssl
