Hi < flavienbwk> how did you end up setting up Prefect Server I know you mentioned that you intended to make some changes to a custom `docker compose yaml`

flavienbwk · Answer

Yes so I ve copied the Prefect docker compose yml without making any modification to it I ve just created a env aside replicating the env variables from the compose file You can see it here <https github com flavienbwk prefect docker compose tree main server> It s working well I ve managed to make it run for agents too So now I want to create my first flow but I don t understand what parameter I should give to my flow to register it to my Prefect API which is in a specific IP not `localhost`

nicholas · Answer

Got it In the case you ll need to provide that specific IP to the `api server` pointing it at the ` 4200 graphql` endpoint Another option is to set this in your local machine s `~ prefect config toml` like this ``` server endpoint= <http your ip 4200 graphql> ```

nicholas · Answer

Glad you got that up and working

flavienbwk · Answer

Yeah Unfortunately that s exactly what I pass to Client ```Client api server= ``` Getting ```requests exceptions HTTPError 400 Client Error Bad Request for url ``` disappointed

nicholas · Answer

Can you confirm that that endpoint is available from your browser You can just paste the address and you should see something like `GET query is missing`

flavienbwk · Answer

When going to ```<http 192 168 254 1 4200 graphql>``` in my browser I get the whole GraphQL interface

nicholas · Answer

Ah ok perfect That means it s running there Are you running that code above from within any sort of container that might not have access to that endpoint

flavienbwk · Answer

I run my scrip from a container yes However it seems to have access as it returns the response immediately When I change the endpoint to an inexistant IP it just times out Moreover I use the same container architecture for my agents And I ve tried entering my container curling the URL and it returns `GET query missing `

nicholas · Answer

Got it Can you try running `prefect backend server` and then re running your script

flavienbwk · Answer

I am getting another error now `prefect utilities exceptions ClientError message Uniqueness violation ` I guess it worked smile

flavienbwk · Answer

Thank you

nicholas · Answer

Perfect

nicholas · Answer

You can set that permanently in your `~ prefect config toml` like this ```backend = server ```

flavienbwk · Answer

OK thank you

flavienbwk · Answer

In the same idea I don t see in the doc how I specify the endpoint of my API to register my task ```flow register project name= weather ```

nicholas · Answer

Did you set the `endpoint` in `~ prefect config toml` as I mentioned above

flavienbwk · Answer

Yes adding the `PREFECT SERVER ENDPOINT` env variable didn t have effect Is it the way of doing By changing the env variables I ll investigate more if it is the case What I don t understand is why I m allowed to specify api server=my ip for Client but not for Flow

nicholas · Answer

Internally `flow register` is creating an instance of `Client ` I m not sure the environment variable has an effect in that case

flavienbwk · Answer

I confirm I was forced to create the `config toml` in order for my script to use a custom API endpoint Is it intentional

nicholas · Answer

Yes that s correct not all configuration options are read in from environment variables particularly those meant for custom Server deployments
