Short Description
UI for Confluent's Schema Registry
Full Description

Schema Registry UI

This is a small docker image you can use to test Landoop's schema-registry-ui.
It serves the schema-registry-ui from port 8000.
A live version can be found at

The software is stateless and the only necessary option is your Schema Registry

To run it:

docker run --rm -p 8000:8000 \
           -e "SCHEMAREGISTRY_URL=http://schema.registry.url" \

Visit http://localhost:8000 to see the UI.

Advanced Settings

Two of the Schema Registry UI settings need to be enabled explicitly. These
are support for global compatibility level configuration support —i.e change the
default compatibility level of your schema registry— and support for transitive
compatibility levels (Schema Registry version 3.1.1 or better). They are handled
by the ALLOW_GLOBAL and ALLOW_TRANSITIVE environment variables. E.g:

docker run --rm -p 8000:8000 \
           -e "SCHEMAREGISTRY_URL=http://schema.registry.url" \
           -e ALLOW_GLOBAL=1 \
           -e ALLOW_TRANSITIVE=1 \

Proxying Schema Registry

If you have CORS issues or want to pass through firewalls and maybe share your
server, we added the PROXY option. Run the container with -e PROXY=true and
Caddy server will proxy the traffic to Schema Registry:

docker run --rm -p 8000:8000 \
           -e "SCHEMAREGISTRY_URL=http://schema.registry.url" \
           -e "PROXY=true" \

Important: When proxying, for the SCHEMAREGISTRY_URL you have to use an
IP address or a domain that can be resolved to it. You can't use
localhost even if you serve Schema Registry from your localhost. The reason
for this is that a docker container has its own network, so your localhost
is different from the container's localhost. As an example, if you are in
your home network and have an IP address of and run Schema
Registry from your computer, instead of http://127.0.1:8082 you must use

If your Schema Registry uses self-signed SSL certificates, you can use the
PROXY_SKIP_VERIFY=true environment variable to instruct the proxy to
not verify the backend TLS certificate.
