Deploying Cog on Kubernetes (on AWS)

Note: Use the excellent helm chart - ohaiwalt/cog-helm to get up quickly on k8s

Follow the guide below to understand the inner workings a bit better.

We will be creating 1 deployment for the cog server and 1 deployment for the relay server.

We chose to run Postgres outside the Kubernetes cluster and provide instructions how to expose all service ports on a single ELB.

Prepararation

0. Create a folder at the root of your user home folder (Example: C:/Users/uname/) called .ssh.
1. Create the following files if they do not already exist (paths begin from the root of your user home folder):

Cog on Kubernetes

This experiment was originally built on Google Cloud's Kubernetes and makes use of gcePersistentDisk. If you are not using Google Cloud, you'll need to adjust the gcePersistentDisk volumes to use the persistent disk technology available in your cluster.

At a high level the steps look something like this, though there may be subtle errors. This experiment happened a few weeks ago and I'm creating these from memory along with the test descriptors I used.

1. Setup Kubernetes and create the necessary persistent disks that are referenced in the deployment.

I have spent quite a bit of time figuring out automounts of NFS shares in OS X...

Somewhere along the line, Apple decided allowing mounts directly into /Volumes should not be possible:

/etc/auto_master (see last line):

#
# Automounter master map
#

+auto_master # Use directory service

#!/bin/bash
file=$1
test -z $file && echo "file required." 1>&2 && exit 1
git filter-branch -f --index-filter "git rm -r --cached $file --ignore-unmatch" --prune-empty --tag-name-filter cat -- --all
git ignore $file
git add .gitignore
git commit -m "Add $file to .gitignore"
