Giant Swarm TODO

This is a simple TODO list demo application that we use to demonstrate some possibilities
enabled by a cloud native stack. This demo is best suited for testing Loki and Linkerd2.

Requirements

There are no real requirements and you can install the application as-is.

Still, if you want to use it with Loki and Linkerd2, please see instructions below.

This application was tested with Loki and Linkerd2 coming from these charts:

Installation

Dependencies

To install loki, run:

helm install --namespace loki -n loki --version 0.2.0 giantswarm-playground/loki-stack-app

To install Linkerd2, run:

helm install --namespace linkerd -n linkerd -f ./helm/configs/linkerd.yaml --version 0.2.1 giantswarm-playground/linkerd2-app

Deployment

This application needs some parameters to setup the MySQL database used as data store. By default it runs
with no persistent storage for mysql. You can start with the default configuration included in the repo:

helm install --name gs-todo --namespace todo --version 0.2.2 giantswarm-playground/giantswarm-todo-app
