We want to use the built in Mendix health check, but can't get it to work. In short the following configuration in the DCOS deployment JSON file: "docker": { "image": "Mx_docker_image", "network": "BRIDGE", "portMappings": [ { "containerPort": 9000, "protocol": "tcp", "labels": { "VIP_1": "/xxxx:9000" } } ], } "env": { "M2EE_admin_port": "9000", "M2EE_admin_pass": "P@ssword!", "M2EE_admin_listen_addresses": "127.0.0.1", } So the other variables defined here do work, but we can't find the port 9000 to be open. Tested by going into the linux machine console and executing: ss -tulpen (command to show all open ports). Are we doing something wrong? Is there a guide to use the Mendix built in healthchecks when running it on a Docker container?
