A experiment running a docker cluster. Runs 3 Tomcat machines and 1 NGinx machine in tandem.

https://tomcat.apache.org/tomcat-7.0-doc/cluster-howto.html

Intentions

Round Robin, Not Sticky
Portainer 9000
NGinx 10080
Tomcat1 10081
Tomcat2 10082
Tomcat3 10083
Tomcat Internal Container Ports: 10080 + 10443 + 10009
80 - your local apache webserver on your computer
8080 - reserved. i avoid using it here

Instructions

Run Portainer so you can view the docker config:

docker run -d --restart unless-stopped -p 9000:9000 -v /var/run/docker.sock:/var/run/docker.sock -v /var:/data portainer/portainer --no-auth

http://192.168.99.100:9000/ or http://localhost:9000/

Start a Tomcat to test it. The container should show up visible within Portainer:

docker run -it --rm -p 8888:8080 tomcat:8.0

docker run -d --rm -p 8888:8080 tomcat:8.0

Run the cluster defined in this project:

docker-compose up

http://192.168.99.100:10080/ or http://localhost:10080/

Notes

In NGINX doesnt start, just make sure there is a logs dir in the nginx folder before you start. It isn't checked into GIT.
