 Configure APIs

The following options allow configuration of the APIs that Orchestration supports. Currently this includes compatibility APIs for CloudFormation and CloudWatch and a native API.

Table 9.10. Description of configuration options for api
Configuration option = Default value Description
[DEFAULT]
heat_metadata_server_url = (StrOpt) URL of the Heat metadata server.
heat_stack_user_role = heat_stack_user (StrOpt) Keystone role for heat template-defined users.
heat_waitcondition_server_url = (StrOpt) URL of the Heat waitcondition server.
heat_watch_server_url = (StrOpt) URL of the Heat CloudWatch server.
max_json_body_size = 1048576 (IntOpt) Maximum raw byte size of JSON request body. Should be larger than max_template_size.
policy_default_rule = default (StrOpt) Rule enforced when requested rule is not found
policy_file = policy.json (StrOpt) JSON file containing policy
secure_proxy_ssl_header = X-Forwarded-Proto (StrOpt) The HTTP Header that will be used to determine which the original request protocol scheme was, even if it was removed by an SSL terminator proxy.
stack_action_timeout = 3600 (IntOpt) Timeout in seconds for stack action (ie. create or update).
stack_domain_admin = None (StrOpt) Keystone username, a user with roles sufficient to manage users and projects in the stack_user_domain.
stack_domain_admin_password = None (StrOpt) Keystone password for stack_domain_admin user.
stack_user_domain = None (StrOpt) Keystone domain ID which contains heat template-defined users.
trusts_delegated_roles = heat_stack_owner (ListOpt) Subset of trustor roles to be delegated to heat.
[auth_password]
allowed_auth_uris = (ListOpt) Allowed keystone endpoints for auth_uri when multi_cloud is enabled. At least one endpoint needs to be specified.
multi_cloud = False (BoolOpt) Allow orchestration of multiple clouds.
[ec2authtoken]
allowed_auth_uris = (ListOpt) Allowed keystone endpoints for auth_uri when multi_cloud is enabled. At least one endpoint needs to be specified.
auth_uri = None (StrOpt) Authentication Endpoint URI.
multi_cloud = False (BoolOpt) Allow orchestration of multiple clouds.
[heat_api]
