<div>You need mesos-dns. </div>

<p dir="ltr">Hi Aaron<br>
Actually both mesos-dns and calico are running even though these containers im \
running are not, yet, using the calico ipaddr specific in json description.<br> So i \
guess it is a problem of bridging, i guess simply specify HOST option on container \
field in Marathon UI</p>

in docker should really be avoided when using marathon/mesos as it implies the \
containers are on the same host, but this will not always be the case when mesos \
schedules your containers (also I think it's being deprecated in docker anyway.. \
not sure though?).<br> <br>
This problem looks like one of service discovery within the mesos cluster: how does \
one service contact the other when it doesn't know which host the other service \
may have landed on?<br> <br>
There are several different solutions for service discovery, you can look into some \
like Project Calico to offer a network layer to docker or try dns based solutions \
like Mesos-dns or Consul (along with mesos-consul). I think marathon also has some \
concept of service discovery built in too if you use something like haproxy.<br> <br>
I hope this helps!<br>

<div>The docker run flag --link is intended to connect the container to another \
running container. I do not know how this would operate in marathon. Perhaps it would \
be an application group which starts up the mysql docker image first, then the \
Wordpress docker image after it.</div> </div>
