~/.rally/openrc doesn't updated from existing deployment config after each fresh deploy. It looks the tenant_name parameter and something else is hard coded just working for keystone v2.

$ cat existing-hakvm-v3.json
{
    "type": "ExistingCloud",
    "auth_url": "https://localhost:5000/v3/",
    "region_name": "regionOne",
    "endpoint_type": "public",

    "admin": {
        "username": "admin",

        "domain_name": "Default",
        "domain_id": "default",
        "user_domain_name": "Default",

~/.rally/openrc was updated

HINTS:
* To get your cloud resources, run:
        rally show [flavors|images|keypairs|networks|secgroups]

* To use standard OpenStack clients, set up your env by running:
        source ~/.rally/openrc
  OpenStack clients are now configured, e.g run:
        glance image-list

$ rally deployment config
{
    "admin": {
        "domain_id": "default",
        "domain_name": "Default",
        "password": "b405..................5bd",
        "project_domain_name": "Default",
        "project_name": "admin",
        "user_domain_name": "Default",
        "username": "admin"
    },
    "admin_port": "35357",
    "auth_url": "https://localhost:5000/v3/",
    "endpoint_type": "public",
    "region_name": "regionOne",
    "type": "ExistingCloud"
}

But when I looking into the openrc, it's not what I deployed and not the same as deployment config:
$ cat ~/.rally/openrc
export OS_AUTH_URL=https://localhost:5000/v3/
export OS_USERNAME=admin
export OS_PASSWORD=b405..................5bd
export OS_TENANT_NAME=admin
export OS_REGION_NAME=regionOne

openrc file is generated by rally so it is okay that it is different from what you passed into rally deployment create command

[Boris Pavlovic (boris-42)]

as sorry you are right seems like we have bug

[Yuki Nishiwaki (uckey-1067)]

I want to confirm this bug.
Do you insist that this bug is lack of environment variables in openrc file ?

[apal (yun-song)]

If you're going to use openrc, then yes.
