The recommended way to install Keep on Kubernetes is via Helm Chart.
Follow these steps to set it up.

​
Prerequisites

​
Helm CLI

See the Helm documentation for instructions about installing helm.

​
Ingress Controller (Optional)

You can skip this step if:
  1. You already have ingress-nginx installed.
  2. You don’t need to expose Keep to the internet/network.

​
Overview

An ingress controller is essential for managing external access to services in your Kubernetes cluster. It acts as a smart router and load balancer, allowing you to expose multiple services through a single entry point while handling SSL termination and routing rules. Keep works best with both ingress-nginx and HAProxy Ingress controllers, but you can customize the helm chart for other ingress controllers too.

​
Nginx Ingress Controller

​
Check ingress-nginx Installed

You check if you already have ingress-nginx installed: 
# By default, the ingress-nginx will be installed under the ingress-nginx namespace
kubectl -n ingress-nginx get pods
NAME                                       READY   STATUS    RESTARTS   AGE
ingress-nginx-controller-d49697d5f-hjhbj   1/1     Running   0          4h19m

# Or check for the ingress class
kubectl get ingressclass
NAME    CONTROLLER             PARAMETERS   AGE
nginx   k8s.io/ingress-nginx   <none>       4h19m

​
Install ingress-nginx

To read about more installation options, see ingress-nginx installation docs.
Since ingress-nginx 4.12, you’ll need to add
--set controller.config.annotations-risk-level=Critical
See https://github.com/kubernetes/ingress-nginx/issues/12618#issuecomment-2566084202
# simplest way to install
# we set snippet-annotations to true to allow rewrites
#   see https://kubernetes.github.io/ingress-nginx/user-guide/nginx-configuration/configmap/#allow-snippet-annotations
helm upgrade --install ingress-nginx ingress-nginx \
  --repo https://kubernetes.github.io/ingress-nginx \
  --set controller.config.allow-snippet-annotations=true \
  --set controller.config.annotations-risk-level=Critical \
  --namespace ingress-nginx --create-namespace
Verify installation: 
kubectl get ingressclass
NAME    CONTROLLER             PARAMETERS   AGE
nginx   k8s.io/ingress-nginx   <none>       4h19m
Verify if snippet annotations are enabled: 
kubectl get configmap -n ingress-nginx ingress-nginx-controller -o yaml | grep allow-snippet-annotations
allow-snippet-annotations: "true"

​
HAProxy Ingress Controller

​
Install ingress-haproxy

To read about more installation options, see haproxy-ingress installation docs.
# simplest way to install
helm upgrade --install haproxy-ingress haproxy-ingress \
  --repo https://haproxy-ingress.github.io/charts \
  --namespace ingress-haproxy --create-namespace
Verify installation: 
kubectl get ingressclass
NAME      CONTROLLER                      PARAMETERS   AGE
haproxy   haproxy-ingress.github.io/controller        <none>        4h19m
Verify if controller is running: 
kubectl get pods -n ingress-haproxy -l app.kubernetes.io/instance=haproxy-ingress
NAME                                READY   STATUS    RESTARTS   AGE
haproxy-ingress-controller-x4n2z   1/1     Running   0          4h19m

​
Installation

# Add the Helm repository
helm repo add keephq https://keephq.github.io/helm-charts

# Install Keep with ingress enabled
helm install keep keephq/keep -n keep --create-namespace

# Add the Helm repository
helm repo add keephq https://keephq.github.io/helm-charts

# Install Keep with ingress enabled
helm install keep keephq/keep -n keep --create-namespace --set global.ingress.className=haproxy

# Add the Helm repository
helm repo add keephq https://keephq.github.io/helm-charts

# Install Keep without ingress enabled.
# You won't be able to access Keep from the network.
helm install keep keephq/keep -n keep --create-namespace \
  --set global.ingress.enabled=false

​
Accessing Keep

​
Ingress

If you installed Keep with ingress, you should be able to access Keep. 
kubectl -n keep get ingress
NAME           CLASS   HOSTS   ADDRESS        PORTS   AGE
keep-ingress   nginx   *       X.X.X.X        80      4h16m
Keep is available at http://X.X.X.X :)

​
Without Ingress (Port-Forwarding)

Use the following commands to access Keep locally without ingress: 
# Forward the UI
kubectl port-forward svc/keep-frontend 3000:3000 -n keep &

# Forward the Backend
kubectl port-forward svc/keep-backend 8080:8080 -n keep &

# Forward WebSocket server (optional)
kubectl port-forward svc/keep-websocket 6001:6001 -n keep &
Keep is available at http://localhost:3000 :)

​
Configuring HTTPS

​
Prerequisites

  1. Domain Name: Example - keep.yourcompany.com
  2. TLS Certificate: Private key (tls.key) and certificate (tls.crt)

​
Create the TLS Secret

Assuming:
  • tls.crt contains the certificate.
  • tls.key contains the private key.
# create the secret with kubectl
kubectl create secret tls keep-tls --cert=./tls.crt --key=./tls.key -n keep

​
Update Helm Values for TLS

helm upgrade -n keep keep keephq/keep \
  --set "global.ingress.hosts[0].host=keep.example.com" \
  --set "global.ingress.tls[0].hosts[0]=keep.example.com" \
  --set "global.ingress.tls[0].secretName=keep-tls"
Alternatively, update your values.yaml: 
...
global:
  ingress:
    hosts:
      - host: keep.example.com
    tls:
      - hosts:
          - keep.example.com
        secretName: keep-tls
...

​
Uninstallation

To remove Keep and clean up: 
helm uninstall keep -n keep
kubectl delete namespace keep
