This commit enables the ability to authenticate to OpenStack by way
of a Keystone Token. Tokens can provide a way to use Terraform and
OpenStack with an expiring, temporary credential. The token will need
to be generated out of band from Terraform.
Official OpenStack clients support specifing custom CA certificate file
that should be used when communicating with OpenStack server. This patch
adds similar behavior to Terraform OpenStack provider, by:
- Using OS_CACERT environmental variable, if available
- Using cacert_file provider parameter, if configured
This commit adds the openstack_lb_member_v1 resource. This resource models a
load balancing member which was previously coupled to the openstack_lb_pool_v1
resource.
By creating an actual member resource, load balancing members can now be
dynamically managed through terraform.
These two provider options are optional though if they are not set,
the user will be prompted to enter values.
By changing them to use the envDefaultFuncAllowMissing, the values
are still passed in the environment if they are set and safely
discarded if they are not.
This commit adds a server group resource. Users can create server
groups with different policies. If a server is launched in a certain
group, the server will adhere to that policy. For example, servers
can be made to all launch on the same compute node or different compute
nodes.
