Docker Singapore - Play with Moby

Play with Moby - Docker Singapore - June 2017

  • Driven by yaml file which defines the assembly we want to create:

    1. kernel (to build bootable vm, stored under /boot) ~> see kernel files info should point to container image which has kernel file (i.e. bzImage) and tar with kernel modules
    2. init: list of images used for init system (unpacked into root filesystem). In case of LinuxKit system this should bring up containerd and system containers

Wait until a port is up

Use netcat to wait until port 8080 is open

while ! nc -z localhost 8080; do sleep 0.1; done; echo test

in a separate session open port 8080 (using netcat):

nc -l 8080

Cog Multi Pod deployment with external Postgres

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.
