How to update components?

Introduction

This document explains how to upgrade a particular component in lokoctl. This includes steps to pull config from upstream.

Find updates

To figure out which component is out dated run the following command in the root of this repository:

./scripts/find-updates.sh

Etcd

Find the old version and newer version from the ./scripts/find-updates.sh script and export it accordingly.

export OLD_VERSION="<old version>"
export NEW_VERSION="<new version>"

Now run the following commands in the root of this repository:

sed -i "s|$OLD_VERSION|$NEW_VERSION|g" assets/terraform-modules/*/flatcar-linux/kubernetes/cl/controller.yaml.tmpl
make update-assets

Releases: https://github.com/etcd-io/etcd/releases .

Calico

To update Calico update the image tags in following files:

assets/charts/control-plane/calico/values.yaml
assets/terraform-modules/bootkube/variables.tf

Update helm chart in assets/charts/control-plane/calico after comparing it with config here .

git checkout ./cert-manager/templates/letsencrypt-clusterissuer-prod.yaml
git checkout ./cert-manager/templates/letsencrypt-clusterissuer-staging.yaml
git checkout ./cert-manager/templates/namespace.yaml
