Connectivity error with schema registry 5.2.1 about schema-registry-ui

[OneCricketeer]

I think you're missing the proxy setting

https://github.com/conduktor/kafka-stack-docker-compose/blob/adaed89009641ad490e0697697e47b35582b7619/full-stack.yml#L57

The property value from the UI container should not be localhost

The solution is to edit and add 2 lines in the schema registry properties

vim etc/schema-registry/schema-registry.properties

Add the following 2 lines

access.control.allow.methods=GET,POST,PUT,OPTIONS
access.control.allow.origin=*

And then start via bin/./confluent start

In a container, you'd use the following environment variables

SCHEMA_REGISTRY_ACCESS_CONTROL_ALLOW_METHODS=GET,POST,PUT,OPTIONS
SCHEMA_REGISTRY_ACCESS_CONTROL_ALLOW_ORIGIN='*'

Hi,

I am hosting the schema-registry which the version of image is also 5.2.1 on kubernetes deployed by helm chart, and I have tried to host a schema-registry-ui by helm chart with the following command:

helm install stable/schema-registry-ui --version 0.4.0 --namespace namespace --name name --set schemaRegistry.url=http://[kubernetes service ip address]

However, the ui returned CONNECTIVITY ERROR after starting up. Also, I have tried to enable the CORS and downgrade the image version to 5.0.2, but the ui still cannot connect to schema-registry.

Is there any solution or suggestion of this trouble?

Same error for me with Kafka 5.3.1 and lastest schema-registry-ui (0.9.5).

Docker compose with settings suggered by @Cricket007 :

    schema-registry-ui:
      image: landoop/schema-registry-ui
      container_name: schema-registry-ui
      depends_on:
        - schema-registry
      ports:
        - 8000:8000
      environment:
        SCHEMAREGISTRY_URL: "http://schema-registry:8081"


    schema-registry:
      image: confluentinc/cp-schema-registry:5.3.1
      container_name: schema-registry
      depends_on:
        - zookeeper
        - kafka
      environment:
        SCHEMA_REGISTRY_HOST_NAME: schema-registry
        SCHEMA_REGISTRY_KAFKASTORE_CONNECTION_URL: zookeeper:2181
        SCHEMA_REGISTRY_ACCESS_CONTROL_ALLOW_METHODS: GET,POST,PUT,OPTIONS
        SCHEMA_REGISTRY_ACCESS_CONTROL_ALLOW_ORIGIN: '*' 

http://schema-registry:8081 or http://localhost:8081 => same error.

My bad !

Thank you very much @Cricket007 . It works !

I was trying to run schema-registry & schema-registry-ui locally, and the PROXY: "true" env var fixed my issue. Thanks, @OneCricketeer.

HI, did anyone find a workaround? Is this project still maintained?
It's a bit sad as this problem doesn't look big, maybe there is a quick fix. I didn't find anything yet. I tried schema registry 5.2.* and 5.3.*, not working. It's also working if I do the curl from @fhuertas from the container that runs schema-registry-ui :(

The ENV PROXY: "true" also fixed it for me. Thanks @OneCricketeer
