Sock Shop on k8s

This repo contains some manifests that allow you to run the Sock Shop microservices demo on k8s.

Requisites

a working kubernetes cluster and kubectl pointing to it.
kubecfg (alternatively you can use the compiled yaml with kubectl).

How to operate

Deploy using kubecfg

$ # define ext variables
$ export EXT_VARS="catalogue.dbPassword=very-secure-password"
$ # deploy the application
$ kubecfg update --ext-str=${EXT_VARS} ./kubecfg/sockshop.jsonnet

Generate raw k8s manifests

$ # define ext variables
$ export EXT_VARS="catalogue.dbPassword=very-secure-password"
$ # generate manifests
$ kubecfg show --ext-str=${EXT_VARS} ./kubecfg/sockshop.jsonnet > sockshop.yaml
$ # sockshop.yaml can be used with kubectl
$ kubectl apply -f sockshop.yaml

Deploy using kubectl (pre-defined EXT_VARS)

This repo also includes sockshop.yaml. It contains a compilation of the k8s manifests with default values for EXT_VARS:

$ kubectl apply -f https://raw.githubusercontent.com/j-fuentes/sockshop-k8s/master/generated/sockshop.yaml

Extra tips

For convenience, you can use the Makefile for common operations (generate, deploy, delete and diff):

$ # print help message
$ make
$ # deploy with default EXT_VARS
$ make deploy

Caveats

NetworkPolicies and GKE

This solution makes use of NetworkPolicies in order to restric the communication between pods to the strictly necessary. If you are using GKE, you might need to enable that feature in your cluster.
