#### Known issues & lessons learned in Swarm:
1. When joining nodes to the cluster (using docker run -d swarm join --addr...), the = between addr is optional.
2. When joining nodes to the cluster (using docker run -d swarm join --addr...), do NOT use tcp:// after --addr.
3. When joining nodes to the cluster (using docker run -d swarm join --addr...), on AWS at least use only the DNS name after --addr.
4. tcp:// is required in the DOCKER_HOST env variable. [ e.g.: export DOCKER_HOST=tcp://<DNS-of-host>:9999 ]
5. In AWS at least, while setting environment variable DOCKER_HOST, use only the DNS hostname and not localhost even if you are on the swarm manager.

SANs: Subject Alternate Names

Service Discovery: A mapping between the logical ID of the container to a concrete (routable) IP:PORT pair must be established and maintained.

Zookeeper: ZooKeeper acts as the master election service in the Mesosphere architecture and stores state for the Mesos nodes.
To find if a node is a Leader or Follower (or Standalone), use the command below:
echo srvr | nc localhost 2181 | grep Mode

docker run -d -p 8888:2375 --name docker-swarm -e SWARM_MESOS_USER=root swarm manage -c mesos-experimental --cluster-opt mesos.address=0.0.0.0 --cluster-opt mesos.port=5050 zk://172.31.0.11:2181/mesos

Overhand: When you just gotta tie a knot.
Double overhand: When you just gotta tie a knot but you don't trust a regular overhand because life is cruel to you.
Figure eight knot: When you need a strong as hell loop that 100% won't fail on you such as when you're climbing mountains or rock walls although anything dangerous like that you should be using a double figure eight.
Running knot: This is barely a knot. Use it to choke yourself while you masturbate in your broom closet you sick fuck.
Granny knot: This is what you get the first two times you try to tie a square knot and fuck it up.
Sheep shank: An actual knot EMSK. Use it to shorten rope. It doesn't take too much pressure but if you put another secure rope through those two end loops it can hold down a trailer load.
Square knot: Another knot EMSK. Turns two pieces of equally thick rope into one. Use it to tie together the ends of your ugly-ass shark tooth necklace.
Bowline: Every sailor knows this but you should definitely know too. You know in movie
