Confluent Cloud Proxy

Use for POCs only

Sample implementation of dockerized HAProxy to expose peered Confluent Cloud clusters to other networks.

Example usage:

docker run -d --net=host \
    -e CKU_COUNT=2 \
    -e ADMIN_API_HOSTNAME=pkac-4rnxk.eastus2.azure.confluent.cloud \
    -e BOOTSTRAP_HOSTNAME=pkc-l9mv5.eastus2.azure.confluent.cloud \
    justinrlee/cc-proxy:1598576167

You can get both the ADMIN API and the HOSTNAME from the Confluent Cloud CLI (leave off the protocol and port for both in the environment variables)

Also, you'll need to point a number of DNS names at the HAProxy instance (or a TCP load balancer in front of HAProxy):

• pkc-l9mv5.eastus2.azure.confluent.cloud
• b0-pkc-l9mv5.eastus2.azure.confluent.cloud
• b1-pkc-l9mv5.eastus2.azure.confluent.cloud
• b2-pkc-l9mv5.eastus2.azure.confluent.cloud
• b3-pkc-l9mv5.eastus2.azure.confluent.cloud
• b4-pkc-l9mv5.eastus2.azure.confluent.cloud
• b5-pkc-l9mv5.eastus2.azure.confluent.cloud
• pkac-4rnxk.eastus2.azure.confluent.cloud
