I have defined the following Jelastic configuration for my environment:
env:
topology:
nodes:
- nodeGroup: bl
nodeType: nginx-dockerized
tag: 1.14.2
displayName: Node balancing
count: 1
fixedCloudlets: 1
cloudlets: 4
env:
DOCKER_EXPOSED_PORT: 22,80,443
- image: jenkins/jenkins:lts
count: 1
cloudlets: 16
nodeGroup: cp
- nodeGroup: sqldb
Now, I want the users of my environment to access my docker application only through the load balancing node. From Jelastic's dashboard, I can't seem to configure any firewall rules for the cp node group. How can I close any connection to the Jenkins node from the outside world and only keep it open from the nginx node?
