Can't seem to expose docker container port to host

I could be missing something ridiculous, but every docker container I have tried to expose to my host machine (Mac) doesn't seem to work. I can tell that the containers are running and appear to have properly been exposed to the port I chose. Am I missing something obvious? Any help would be greatly appreciated.

I pulled down latest ElasticSearch image: https://www.elastic.co/guide/en/elasticsearch/reference/current/docker.html

Run Docker: docker run -d -p 9200:9200 docker.elastic.co/elasticsearch/elasticsearch:5.4.0

Request to see running images: docker ps

View running image: 5e8ae3b13f7c docker.elastic.co/elasticsearch/elasticsearch:5.4.0 "/bin/bash bin/es-..." 4 seconds ago Up 4 seconds 0.0.0.0:9200->9200/tcp, 9300/tcp eloquent_almeida

Run lsof to see if anything exposed on port 9200 lsof -i tcp:9200

Nothing returned

Mac OS: 10.12.4

Docker Updated Version:

docker version

 Version:      17.04.0-ce

Downloaded nmap and ran against 9200 localhost. Also made sure 9200 is open now in /etc/pf.conf. 

Nmap scan report for localhost (127.0.0.1)
Host is up (0.00016s latency).
Other addresses for localhost (not scanned): ::1
PORT     STATE  SERVICE
9200/tcp closed wap-wsp

Also tried using docker-machine on mac's IP:

docker-machine ip default
192.168.99.100

Tried 192.168.99.100:9200 and still no luck

You know, it looks like something is wrong with downloaded image or docker installation. I repeated your steps - all is Ok: 

[06:40 PM] borlaze@mac: /tmp $ docker run -d -p 9200:9200 docker.elastic.co/elasticsearch/elasticsearch:5.4.0

[06:41 PM] borlaze@mac: /tmp $ docker ps

Try to remove image and repeat.
