Recommendations for Docker Networking and Load Balancing

sjohnkennedy · February 12, 2020, 6:00pm

Hello Community,

Wanted to see if there any recommendations on creating docker networks and Load balancing the DAP containers on docker hosts.

Also CyberArk recommendations on hardening docker hosts and Vault Synchorniser

Howdy - feel free to use anything in the ConjurDemos github repo. This script will startup a load-balanced, HA cluster on one VM, where the containers connect over a docker network.

github.com

conjurdemos/simple-oc-k8s-poc/blob/master/1_master/strt_cluster

#!/bin/bash 
set -eo pipefail

source ../config/dap.config
source ../config/$PLATFORM.config
source ../config/utils.sh

# Starts an DAP Master HA cluster

main() {
  ./stp_cluster
  master_network_up
  shared_volumes_up
  master_up
  start_standbys
  haproxy_up
  cli_up
  ./enable_dap_node_for_k8s.sh
  cluster_up
  configure_standbys

Cheers,

Jody

Thank you. I will check that out. I was trying to see how this can done when docker containers are in different hosts rather than a single one. Should we setup a docker Overlay network and connect the containers to it and put the the load balancer on top of it? I am not sure how we can achieve that with docker bridge network
