Kubernetes multi data centre with consul

Enterprise edition moved to private

Prerequisites

Install:

1. Go
2. CloudFlare's SSL ToolKit (cfssl and cfssljson)
3. Consul

Once installed, create a workspace, configure the GOPATH and add the workspace's bin folder to your system path:

$ mkdir $HOME/go
$ export GOPATH=$HOME/go
$ export PATH=$PATH:$GOPATH/bin

Next, install the SSL ToolKit:

$ go get -u github.com/cloudflare/cfssl/cmd/cfssl
$ go get -u github.com/cloudflare/cfssl/cmd/cfssljson

TLS Certificates

Create a Certificate Authority:

$ cfssl gencert -initca certs/config/ca-csr.json | cfssljson -bare certs/ca

Create the private keys and TLS certificates:

$ cfssl gencert \
    -ca=certs/ca.pem \
    -ca-key=certs/ca-key.pem \
    -config=certs/config/ca-config.json \
    -profile=default \
    certs/config/consul-csr.json | cfssljson -bare certs/consul

You should now see the following PEM files within the "certs" directory:

ca-key.pem
ca.pem
consul-key.pem
consul.pem

Spin up Consul on Kubernetes:

$ sh create.sh

Forward the port to the local machine for consul:

$ kubectl -n vault port-forward consul-1 8500:8500
