    Configure Mesos

These instructions are derived from those in the Mesos Community Documentation.
Do the below as root.

EOF

cat <<EOF >> /etc/zookeeper/conf/zoo.cfg

cat <<EOF >> /etc/mesos/zk
zk://`hostname`:2181/mesos
EOF

cat <<EOF >> /etc/mesos-master/quorum

Configure Mesos Containerizer

Configure Mesos to use the Mesos containerizer with docker image support.
cat <<EOF >> /etc/mesos-slave/containerizers

{
  "JAVA_HOME": "/usr/lib/jvm/java-8-openjdk-amd64"
}
EOF

Start

Start the services.
sudo service zookeeper restart
sudo service mesos-master restart
sudo service mesos-slave restart

Verify

Verify that Mesos is running normally.
MASTER=$(mesos-resolve `cat /etc/mesos/zk`)
mesos-execute --master=$MASTER --name="cluster-test" --command="sleep 5"
