is `PREFECT_SERVER__GRAPHQL_URL` the right env variable for the UI docker image? it seems to be the one used in the docker compose file but when ran outside of docker (so not on localhost), it doesn’t seem to be working :confused:

Hi <@U018E2ZM6VB> - are you running the UI <https://github.com/PrefectHQ/ui|from the new repo> or from an older version of Server?

should I use `VUE_APP_SERVER_URL` instead? <https://github.com/PrefectHQ/ui/blob/d873d4408e11b3b660107f38c66f8541038cf68f/src/store/api/index.js#L16>

Gotcha <@U018E2ZM6VB> - what are you trying to do?

well… simply set the proper graphql endpoint which is not localhost in my deployment?!?

Yes I can do it directly from the UI but it only updates a key in the local storage

so everyone that connect to the UI would have to do it too

Ah I see - `VUE_APP_SERVER_URL` is the correct environment variable; the reason it's not updating the default in your UI is that the UI needs to be rebuilt when environment variables are updated

We don't have a great way of updating the default in the built application, because it's an interpolated constant variable

right… so this:
```      PREFECT_SERVER__GRAPHQL_URL: ${GRAPHQL_URL:-<http://localhost:4200/graphql>}```
in
```  ui:
    image: "prefecthq/ui:${PREFECT_UI_TAG:-latest}"
    ports:
      - "${UI_HOST_PORT:-8080}:8080"
    command: "/intercept.sh"
    environment:
      PREFECT_SERVER__GRAPHQL_URL: ${GRAPHQL_URL:-<http://localhost:4200/graphql>}
    networks:
      - prefect-server
    restart: "always"
    depends_on:
      - apollo```
from `prefect/cli/docker-compose.yml` is meaningless for the moment?

That's correct <@U018E2ZM6VB> - I think we kept that for backwards compatibility with the old version of Server.

I'm going to open a ticket for the UI to have a more concrete way of setting a default graphql endpoint

now that I managed to put the UI and graphql behind the same endpoint to avoid CORS cross-site issue, I got a little sad to be blocked there :stuck_out_tongue:

In the meantime, if you want to update the `VUE_APP_SERVER_URL` in your  `.env` file, you can run `npm install` and `npm run build` on the repo to rebuild the application with your new endpoint

Note that those will require you to have Node and NPM installed

That’s fine I am in no rush since this is meant to be tried/poced in September/Q4

if you have a ticket tho I wouldn’t mind you posting it here so that I can follow it

Creating it as we speak :slightly_smiling_face:
