The Architecture

Below is a sample architecture, no workers for this example :-)

VIP 192.168.0.40
K8S01 192.168.0.41
K8S02 192.168.0.42
DB01 192.168.0.43

Create our DB on DB01

To set-up wal shipping in primary cluster:

In the file manifests/configmap.yaml, uncomment the line containing wal_s3_bucket and set it to the bucket name created in MinIO.
And then, add the following lines to the same file:

  pod_environment_configmap: postgres-pod-config
---
apiVersion: v1
kind: ConfigMap
metadata:

Generate ssl certificates with Subject Alt Names on OSX

Open ssl.conf in a text editor.

Edit the domain(s) listed under the [alt_names] section so that they match the local domain name you want to use for your project, e.g.

DNS.1   = my-project.dev

Additional FQDNs can be added if required:

HOWTO: Create Your Own Self-Signed Certificate with Subject Alternative Names Using OpenSSL in Ubuntu Bash for Window

Overview

My main development workstation is a Windows 10 machine, so we'll approach this from that viewpoint.

Recently, Google Chrome started giving me a warning when I open a site that uses https and self-signed certificate on my local development machine due to some SSL certificate issues like the one below:

Mesos-DNS

Scripts for setting up

sudo mkdir /etc/mesos-dns
sudo vi /etc/mesos-dns/config.json

config.json

How to compile Mesos on your new Raspberry Pi 2 (which is amazing with 4 cores and 6x performance). Follows on from experiments in compiling for OS X

sudo apt-get install maven libsasl2-dev libapr1-dev libsvn-dev libcurl4-openssl-dev python-dev python-boto

export JAVA_HOME="/usr/lib/jvm/jdk-8-oracle-arm-vfp-hflt"
export PATH=$JAVA_HOME/bin:$PATH
