Using Mistral without Authentication

It is possible to execute a workflow on any arbitrary cloud without additional configuration on the Mistral server side. If authentication is turned off in the Mistral server (Pecan's auth_enable = False option in mistral.conf), there is no need to set the keystone_authtoken section. It is possible to have Mistral use an external OpenStack cloud even when it isn't deployed in an OpenStack environment (i.e. no Keystone integration).

This setup is particularly useful when Mistral is used in standalone mode, where the Mistral service is not part of the OpenStack cloud and runs separately.

To enable this operation, the user can use --os-target-username, --os-target-password, --os-target-tenant-id, --os-target-tenant-name, --os-target-auth-token, --os-target-auth-url, --os-target_cacert, and --os-target-region-name parameters.

For example, the user can return the heat stack list with this setup as shown below:

$ mistral \
    --os-target-auth-url=http://keystone2.example.com:5000/v3 \
    --os-target-username=testuser \
    --os-target-tenant=testtenant \
    --os-target-password="MistralRuleZ" \
    --os-mistral-url=http://mistral.example.com:8989/v2 \
    run-action heat.stacks_list

The OS-TARGET-* parameters can be set in environment variables as:

$ export OS_TARGET_AUTH_URL=http://keystone2.example.com:5000/v3
$ export OS_TARGET_USERNAME=admin
$ export OS_TARGET_TENANT_NAME=tenant
$ export OS_TARGET_PASSWORD=secret
$ export OS_TARGET_REGION_NAME=region
