Helmfile

Below are two examples of helmfile in action. One a simple single helmfile for testing and the second a more realistic example to be used in production.

Basic helmfile example

This is a very simple one file example of a helmfile to deploy two rococo-local relaychain validators along with two parachains statemint-dev and contracts-rococo-dev. It is intended for basic testing and familiarization of helmfile.

A more real world example is listed below which comes from the testnet-manager repo. A nginx container will also be deployed to host chain spec files.

Steps:

• Create a helmfile based on the simple example below and name it helmfile.yaml

• Install a web server to host helmfiles using kubectl create -f https://raw.githubusercontent.com/paritytech/testnet-manager/main/local-kubernetes/kube-setup/validators-chainspec.yml

• Add relaychain and parachains using: helmfile sync

Real world helmfile example

You can find a good reference helmfile example at the testnet-manager examples folder.
