Should we include the STAC_FASTAPI_VERSION from the pr in stac-fastapi? api_version=os.getenv("STAC_FASTAPI_VERSION", "2.1")) Also, should these have more specific default values? The title here for instance could be stac-fastapi.elasticsearch. The api version would be 2.1. If we could pull the default version in from the version file?

[jamesfisher-geo]

Yeah, good call. I will make those changes

[jonhealy1]

We could add the new env vars to the app-opensearch and app-elasticsearch in the docker-compose.yml file too. It might help people realize that they can change those things.

[jamesfisher-geo]

Cool. Added that as well

[jonhealy1]

Looks great

@jonhealy1 Could not really follow the discussion in #639 and #657. Are there any change needed to this?

[jonhealy1]

I think the ENV variable names/ meanings may have changed, it's still nice to have our own defaults. We should probably include all of these. Once v2.5.0 is released we can update and make sure everything works. What do you think? I may be missing something here.

- `STAC_FASTAPI_VERSION` (string) is the version number of your API instance (this is not the STAC version).
- `STAC FASTAPI_TITLE` (string) should be a self-explanatory title for your API.
- `STAC FASTAPI_DESCRIPTION` (string) should be a good description for your API. It can contain CommonMark.
- `STAC_FASTAPI_LANDING_ID` (string) is a unique identifier for your Landing page.```

Sounds great. Would the defaults be defined when instantiating StacApi like below? Or will they be defined in a separate app config file?

api = StacApi(
    title=os.getenv("STAC_FASTAPI_TITLE", "stac-fastapi-elasticsearch"),
    description=os.getenv("STAC_FASTAPI_DESCRIPTION", "stac-fastapi-elasticsearch"),
    api_version=os.getenv("STAC_FASTAPI_VERSION", "2.1"),
    settings=settings,
    extensions=extensions,
    client=CoreClient(
        database=database_logic, session=session, post_request_model=post_request_model
    ),
    search_get_request_model=create_get_request_model(extensions),
    search_post_request_model=post_request_model,
)

we could add something like this to the config file and then import them if we want: https://github.com/stac-utils/stac-fastapi/blob/f7d2eb3c30bef338e3bf6cce5c425b531a653a5e/stac_fastapi/types/stac_fastapi/types/config.py#L7-L42
