I have mesos installed in some docker containers and when ever I bring the container up, the mesos-master process starts by default on all these containers. Even on those that I have mesos-agents running on.
I have no idea why this is happening and this is rather annoying.
I am installing mesos the following way
RUN rpm -i http://repos.mesosphere.io/el/7/noarch/RPMS/mesosphere-el-repo-7-1.noarch.rpm && \
yum -y install mesos-0.28.2
Any ideas on why this is happening? Is this the expected behavior? Please let me know what I can do to stop this.
This is expected behavior
You need to explicit disable Mesos Master (and ZooKeeper if you installed it). Depending on your system version it can be done as follow:
On RedHat 6 / CentOS 6:
sudo stop mesos-master
sudo sh -c "echo manual > /etc/init/mesos-master.override"
On RedHat 7 / CentOS 7:
sudo systemctl stop mesos-master.service
sudo systemctl disable mesos-master.service
