Duplicated Consul services #68

Open scalp42 opened 8 years ago

scalp42 commented 8 years ago

I have one app in Marathon, two tasks/instances for it on 2 different Mesos slaves, yet I see 4 services for it:

ChrisAubuchon commented 8 years ago

Are there multiple ports for each task? Can you post the service id for these?

scalp42 commented 8 years ago

@ChrisAubuchon indeed there are two ports for the task:

      "portMappings": [
        {
          "containerPort": 8080,
          "servicePort": 60010,
          "hostPort": 0,
          "protocol": "tcp"
        },
        {
          "containerPort": 8081,
          "servicePort": 60011,
          "hostPort": 0,
          "protocol": "tcp"
        }
      ]

Unless I'm mistaken, wouldn't it be better to just return, let's say the first port ? In case of SRV records:

scalp@i-6a2965ae ~ $ dig audit-green-talkk-prod.service.consul SRV +tcp

Or maybe be able to specify the portIndex like Marathon does for the health checks. Just curious.

Thanks for quick answer! :smile:
