Missing environment variables ?

[Doooooo0o]

so far I've added :

export MASTER="{{ master_ip_address }}:{{ mesos_master_port }}"

to the slaves
and

export ZK="{{ mesos_zookeeper_masters }}"
export IP="{{ ansible_eth1.ipv4.address }}"

to the master

Otherwise /usr/bin/mesos-init-wrapper is using default values for slaves :

  [[ ! ${MASTER:-} ]]    || args+=( --master="$MASTER" )

as well for master :

  [[ ! ${ZK:-} ]]      || args+=( --zk="$ZK" )
  [[ ! ${IP:-} ]]      || args+=( --ip="$IP" )

maybe I was missing something on the playbook execution

they @theonlydoo the most important (not environment variable) is

zookeeper_hostnames: "{{ mesos_hostname }}:{{ zookeeper_client_port }}"

which tells Mesos where Zookeeper instance lives and then can register itself and its standby masters which later are use in auto discovery by frameworks such as Apache Marathon.
