Because Docker Desktop for Mac does not provide access to container IP from host(macOS). This can result in host(macOS) and containers not being able to access each other's internal services directly over IPs. The mac-docker-connector provides the ability for the macOS host to directly access the docker container IP. Before running the integration tests, make sure to execute the dev/docker/tools/mac-docker-connector.sh script.
Developing Apache Gravitino in a linux environment does not have this limitation and does not require executing the
mac-docker-connector.shscript ahead of time.
