Helm 3

Helm is a package manager for Kubernetes. It allows you to install and manage applications on Kubernetes.

Setup EasyHAProxy with Helm 3

1) Identify the node where your EasyHAProxy container will run

EasyHAProxy will be limited to a single node. To understand that see limitations page.

$ kubectl get nodes

NAME      STATUS   ROLES    AGE    VERSION
node-01   Ready    <none>   561d   v1.21.13-3
node-02   Ready    <none>   561d   v1.21.13-3

Add the EasyHAProxy label to the node.

kubectl label nodes node-01 "easyhaproxy/node=master"

2) Install EasyHAProxy

Minimal configuration

helm repo add byjg https://opensource.byjg.com/helm
helm repo update byjg
kubectl create namespace easyhaproxy

helm upgrade --install ingress byjg/easyhaproxy \
    --namespace easyhaproxy \
    --set resources.requests.cpu=100m \
    --set resources.requests.memory=128Mi
