This is the repository to build multi-az MongoDb cluster.
You need to configure subnet(vswitch) and CIDR, mongodb instance spec.
Provisioning scripts(provision_mongo.sh and provision_snat.sh) will provision mongoadmin user. In order to manage MongoDB, you can login as mongodadmin user. So, you need to configure your publickey and privatekey to terraform.tfvars.
Following is example of terraform.tfvars.
