I changed all 8080 ports to 8082 in docker-file.yml due to port conflict. As a result, Datahub frontend can not connect Datahub gms.

Gentle reminder to please post large blocks of code/stack trace in Slack message threads - it’s a HUGE help for the Core Team to keep track of which questions are still unaddressed across our various support channels!

since you are using quickstart, you can just do this with

DATAHUB_MAPPED_GMS_PORT=8082 datahub docker quickstart
