With the file environments/CLOUDPROVIDER.tfvars the parameters of the environment CLOUDPROVIDER can be adjusted.

image             = "OSISM base"
openstack_version = "yoga"

Beyond the terraform variables, you can enable special overrides by adding special comments into the .tfvars files. The syntax is # override:XXXX. This will include the file overrides/XXXX_override.tf into the terraform deployment.

Currently two such overrides exist:

  • neutron_availability_zone_hints: This enables using network availability zone hints. betacloud and citycloud benefit from this.

  • neutron_router_enable_snat: This passes enable_snat: true for the router. This is required by OTC.

Via the variable prefix it is possible to change the name of the created resources. By default, testbed is used. With this variable it is possible to run several testbeds within one project.

Local Environment

For local overrides local.env and environments/local.tfvars can be used. Remember to also add a local entry to clouds.yaml.

cp environments/local.tfvars.sample environments/local.tfvars
echo ENVIRONMENT=local >> local.env
