Staging Environment for the Microservice Demo

Setup cluster

Use the scripts in this directory to set up a Kubernetes cluster on AWS from a Bastion host.

• Create a bastion host in AWS

• Install terraform

• Clone this repository

• Copy terraform.tfvars.example to terraform.tfvars and enter the missing information. Look for a description of the variables in variables.tf.

• Plan the terraform run: terraform plan -out staging.plan

• If all looks well, apply the plan: terraform apply staging.plan.

  If it somehow fails, destroy the cluster with terraform destroy -force and try again.

• Access the Sock Shop via the elb url displayed when you run terraform output. Weave Scope/Flux should be visible from Weave Cloud.

Kubectl

• kubectl should work from the bastion to control the kubernetes cluster

Setup/Control Weave Flux

• To gain control of flux download the binary from here, and export the Weave Cloud flux token.

  export FLUX_SERVICE_TOKEN=<sock shop weave cloud token>
  

• To make changes to the flux config you can run get-config to download the current config.

  fluxctl get-config > flux.conf
  

• Fill in missing values, and run fluxctl set-config --file=flux.conf

• To set sock-shop services to update automatically you can set it with the command below

  for svc in front-end catalogue orders queue-master user cart catalogue user-db catalogue-db payment shipping; do
    fluxctl automate --service=sock-shop/$svc
  done
