How can I configure OpenStack authentication for Terraform?

Question

I want to use some company terraform files. They all rely on authentication to OpenStack which is the resource they're provisioning from. How can I configure this?

Answer 1

It depends on your proivder stansa,

provider "openstack" {
  # stuff
}

It should look something like the above. If it has,

• auth_url defined, then it also will very likely have application_credential_name and application_credential_secret defined.
• cloud defined, then it's looking for your OpenStack clouds.yaml. (Note this is distinct from cloud.cfg) Your clouds.yaml
  • is documented in OpenStack
  • can be exported from Horizons, the web interface,
  • typically resides in $HOME/.config/openstack, and applies for the user. But can also be in the local directory, or installed globally in /etc/openstack.
• Has neither auth_url nor cloud, in which case Terraform will try to authenticate with environmental variables which are documented here
