Kubernetes

This page provides instructions on how to configure the Helm chart to install Hoop in any cloud provider.

Quick Start

Setup Postgres Database

Create a new namespace and install a Postgres database in your Kubernetes cluster

Database Setup

Create a namespace

kubectl create ns hoopdev

Save the deployment assets to a local file

cat - > /tmp/postgres-spec.yml <<EOF

  - name: postgres
    port: 5432
    protocol: TCP
    targetPort: 5432
  selector:
    app: postgres
EOF

Deploy it

kubectl -n hoopdev apply -f /tmp/postgres-spec.yml

This installation is using a Postgres role with super privileges. Refer to Database Configuration for hosted database setups.

Configure the values.yml

JWT_SECRET_KEY=$(openssl rand 64 | base64)
cat - > ./values.yaml <<EOF
config:
  POSTGRES_DB_URI: 'postgres://root:1a2b3c4d@postgres.hoopdev:5432/hoopdb?sslmode=disable'
  API_URL: 'http://127.0.0.1:8009'
  JWT_SECRET_KEY: "$JWT_SECRET_KEY"

defaultAgent:
  enabled: true
EOF

Deploy the Gateway

VERSION=$(curl -s https://releases.hoop.dev/release/latest.txt)
helm upgrade --install hoop \
  oci://ghcr.io/hoophq/helm-charts/hoop-chart --version $VERSION \
  -f values.yaml \
  --namespace hoopdev

Access it

Forward the hoopgateway service ports to your local machine to access the WebApp

kubectl port-forward service/hoopgateway 8009:8009 -n hoopdev

Visit the Webapp at http://127.0.0.1:8009/login

Installing

To install the latest version in a new namespace (example: hoopdev). Issue the command below:

VERSION=$(curl -s https://releases.hoop.dev/release/latest.txt)
helm upgrade --install hoop \
  oci://ghcr.io/hoophq/helm-charts/hoop-chart --version $VERSION \
  -f values.yaml \
  --namespace hoopdev

Overwriting or passing new attributes

It is possible to add new attributes or overwrite an attribute from a base values.yaml file. In the example below a default agent is deployed as a sidecar container.

helm upgrade --install hoop \
  oci://ghcr.io/hoophq/helm-charts/hoop-chart --version $VERSION \
  -f values.yaml \
  --set defaultAgent.enabled=true

Database Configuration

Hoop uses Postgres as the backend storage of all data in the system. The user that connects in the database must be a superuser or have the CREATEROLE permission. The command below creates a database and a user with privileges to access the database and the default schema.

CREATE DATABASE hoopdb;
CREATE USER hoopuser WITH ENCRYPTED PASSWORD 'my-secure-password' CREATEROLE;
-- switch to the created database
\c hoopdb
GRANT ALL PRIVILEGES ON DATABASE hoopdb TO hoopuser;
GRANT ALL PRIVILEGES ON SCHEMA public to hoopuser;
GRANT ALL PRIVILEGES ON ALL TABLES IN SCHEMA public TO hoopuser;

In case of using a password with special characters, make sure to url encode it properly when setting the connection string.

Use these values to assemble the configuration for POSTGRES_DB_URI:

POSTGRES_DB_URI=postgres://hoopuser:<passwd>@<db-host>:5432/hoopdb

Make sure to include ?sslmode=disable option in the Postgres connection string in case your database setup doesn’t support TLS.

Helm

Make sure you have helm installed in your machine. Check Helm installation page

VERSION=$(curl -s https://releases.hoop.dev/release/latest.txt)
helm upgrade --install hoopagent \
	oci://ghcr.io/hoophq/helm-charts/hoopagent-chart --version $VERSION \
	--set "config.HOOP_KEY=<AUTH-KEY>"

Using Helm Manifests

VERSION=$(curl -s https://releases.hoop.dev/release/latest.txt)
helm template hoopagent \
  oci://ghcr.io/hoophq/helm-charts/hoopagent-chart --version $VERSION \
  --set 'config.HOOP_KEY=<AUTH-KEY>' \
  --set 'image.tag=1.25.2' \
  --set 'extraSecret=AWS_REGION=us-east-1'

Starting from version 1.21.9, there is only one way to configure the agent key, which is by using the config.HOOP_KEY configuration. This requires creating a key in a DSN format in the API. To use legacy options, use the Helm chart version 1.21.4.

Authentication

Local Authentication manages users and passwords locally and sign JWT access tokens to users. Make sure to create a strong secret key for JWT_SECRET_KEY configuration, the command below generate a strong key as the value for this configuration:

openssl rand 64 | base64

config:
  POSTGRES_DB_URI: 'postgres://<user>:<pwd>@<db-host>:<port>/<dbname>'
  API_URL: 'https://hoopdev.yourdomain.tld'
  AUTH_METHOD: local
  JWT_SECRET_KEY: '<secure-secret-key>'

openssl rand 64 | base64

config:
  POSTGRES_DB_URI: 'postgres://<user>:<pwd>@<db-host>:<port>/<dbname>'
  API_URL: 'https://hoopdev.yourdomain.tld'
  AUTH_METHOD: local
  JWT_SECRET_KEY: '<secure-secret-key>'

The Oauth2/OIDC authentication integrates with any identity provider that support these protocols. The users are managed on the identity provider.

config:
  POSTGRES_DB_URI: 'postgres://<user>:<pwd>@<db-host>:<port>/<dbname>'
  API_URL: 'https://hoopdev.yourdomain.tld'
  IDP_ISSUER: 'https://idp-issuer-url'
  IDP_CLIENT_ID: 'client-id'
  IDP_CLIENT_SECRET: 'client-secret'
  IDP_AUDIENCE: ''
  IDP_CUSTOM_SCOPES: ''
  IDP_GROUPS_CLAIM: ''

Persistence

We recommend using persistent volumes for session blobs to avoid losing sessions during outages or restarts. The following example shows how to enable a 100GB persistent volume when using AWS/EKS.

persistence:
  # -- Use persistent volume for write ahead log sessions
  enabled: true
  storageClassName: gp2

  # -- Size of persistent volume claim
  size: 100Gi

Ingress Configuration

This section covers the ingress configuration. The gateway requires exposing the ports HTTP/8009 and HTTP2/8010. The ingress configuration establishes these two differing configurations based on the ingress controller in use.

AWS Load Balancer Controller is a controller to help manage Elastic Load Balancers for a Kubernetes cluster.

The Nginx Ingress Controller is an Ingress controller for Kubernetes using NGINX as a reverse proxy and load balancer.

Deploy Nginx Ingress Controller

https://kubernetes.github.io/ingress-nginx/deploy/

Ingress Configuration

TLS Termination on Nginx

ingressApi:
  enabled: true
  host: hoopgateway.yourdomain.tld
  ingressClassName: 'nginx'
  tls:
  - hosts:
      - hoopgateway.yourdomain.tld
    secretName: hoopserver-tls

ingressGrpc:
  enabled: true
  host: "hoop-grpc.yourdomain.tld"
  annotations:
    nginx.ingress.kubernetes.io/backend-protocol: GRPC
    nginx.ingress.kubernetes.io/proxy-body-size: '0'
  tls:
  - hosts:
      - hoop-grpc.yourdomain.tld
    secretName: hoopserver-tls

This setup requires deploying a network load balancer (Layer 4) in your cloud provider.

The external Application Load Balancer is a proxy-based Layer 7 load balancer that enables you to run and scale your services behind a single external IP address. See the Architecture Overview.

The Classic ALB doesn’t support establishing HTTP/2 connections with the Hoop Gateway without TLS. To accommodate this requirement, TLS certificates must be configured both on the ALB and within the Hoop Gateway to establish secure communication between these components.

Deploy GKE Cluster

Deploy GKE Cluster by following the GKE Quick Start guide
Obtain access to your cluster via kubectl

Export your domain name

export DOMAIN_HOSTNAME=hoopgateway.yourdomain.tld

Setup Certificates

Generate self signed certificates

This step is not necessary if you already have certificates issued by a known entity.

Create the CA private key

mkdir -p /tmp/hoopdemo && cd /tmp/hoopdemo
openssl genrsa -aes256 -out ca.key 2048

Create the Root Certificate Authority (CA)

openssl req -x509 -new -nodes -key ca.key -sha256 -days 1826 -out ca.crt -subj '/CN=Hoop Root CA'

Creating the Certificate Signing Request (CSR)

openssl req -new -nodes -out server.csr -newkey rsa:2048 -keyout server.key -subj '/CN=HoopGateway'

Sign the Certificate

# create a v3 ext file for SAN properties
cat > server.v3.ext << EOF
authorityKeyIdentifier=keyid,issuer
basicConstraints=CA:FALSE
keyUsage = digitalSignature, nonRepudiation, keyEncipherment, dataEncipherment
subjectAltName = @alt_names
[alt_names]
DNS.1 = $DOMAIN_HOSTNAME
DNS.2 = grpc-$DOMAIN_HOSTNAME
IP.1 = 127.0.0.1
EOF

openssl x509 -req -in server.csr -CA ca.crt -CAkey ca.key \
    -CAcreateserial -out server.crt -days 730 -sha256 -extfile server.v3.ext

Make sure to install the Root Certificate Authority in your browser/system to be able to visit the Web App. The browser won’t allow access due to HSTS policy.

This step is not necessary when using certificates issued by a known entity.

Export the certificates for setting up the helm chart

export TLS_CA="base64://$(cat ca.crt | base64)"
export TLS_KEY="base64://$(cat server.key | base64)"
export TLS_CERT="base64://$(cat server.crt | base64)"

The format base64://<inline-certificate-content> allows configuring inline TLS to Hoop Gateway.

Upload them into GCP

gcloud compute ssl-certificates create hoopserver \
  --certificate=server.crt \
  --private-key=server.key

We recommend using a valid certificates for production workloads.

Configure DNS and create static Global IP Addresses

Create the ip addresses of the load balancer

gcloud compute addresses create hoopgateway-grpc --global
gcloud compute addresses create hoopgateway-http --global

Associate the ip address to the proper domains in your DNS provider

Public DNS	IP Address
`$DOMAIN_HOSTNAME`	`<hoopgateway-http-ip-address>`
`grpc-$DOMAIN_HOSTNAME`	`<hoopgateway-grpc-ip-address>`

Deploy the Hoop Gateway

Create a namespace

kubectl create ns hoopdemo

Deploy a Postgres Server

Access It

Wait for all resources to be provisioned, the command below will show any pending operations on GCP

gcloud compute operations list |grep -v DONE

Check if the ip addresses are displayed when listing the ingresses

kubectl get ing -n hoopdemo

hoopgateway-web    <none>   $DOMAIN_HOSTNAME        XX.XXX.XXX.X

Navigate to the Web Application public URL at https://$DOMAIN_HOSTNAME/login

Service Configuration

The chart allows configuring the main service that exposes the service of the gateway.

mainService:
  annotations:
    beta.cloud.google.com/backend-config: '{"ports": {"http": "hoopgateway-http", "grpc": "hoopgateway-grpc"}}'
    cloud.google.com/app-protocols: '{"http":"HTTPS", "grpc":"HTTP2"}'
  httpBackendConfig:
    healthCheckType: HTTPS
  grpcBackendConfig:
    healthCheckType: HTTPS
    timeoutSec: 259200

mainService.annotations attribute allows adding an annotation mapping. GCP for instance configure aspects of how to configure the load balancer based on this configuration
mainService.httpBackendConfig: It creates the hoopgateway-http Backend Config resource when this attribute is set. It could be referenced using the annotation beta.cloud.google.com/backend-config
- healthCheckType: The protocol used by probe systems for health checking. The BackendConfig only supports creating health checks using the HTTP, HTTPS, or HTTP2
- timeoutSec: The amount of time in seconds that Google Cloud waits for a response to a probe.
mainService.grpcBackendConfig: It creates the hoopgateway-grpc Backend Config resource when this attribute is set. It could be referenced using the annotation beta.cloud.google.com/backend-config
- healthCheckType: The protocol used by probe systems for health checking. The BackendConfig only supports creating health checks using the HTTP, HTTPS, or HTTP2
- timeoutSec: The amount of time in seconds that Google Cloud waits for a response to a probe.

For more information of how to configure these resources, refer to the GCP Ingress Configuration Reference.

Computing Resources

The helm-chart defaults to 1vCPU and 1GB, which is suitable for evaluation purposes only. For production setups, we recommend allocating at least 8GB/4vCPU to the gateway process.

resources:
  gw:
    limits:
      cpu: 4096m
      memory: 8Gi
    requests:
      cpu: 4096m
      memory: 8Gi

Image Configuration

By default, the latest version of all images is used. If you want to use a specific image or pin the versions, use the image attribute section.

image:
  gw:
    repository: hoophq/hoop
    pullPolicy: Always
    tag: latest

Default Agent Sidecar

Adding this section will deploy a default agent as a sidecar container.

defaultAgent:
  enabled: true
  imageRepository: 'hoophq/hoopdev'
  imageTag: latest
  imagePullPolicy: Always
  grpcHost: 127.0.0.1:8009

The grpcHost allows configuring the host to connect when starting the agent. In case the gateway has TLS configured (TLS_CA env set), the host must match the certificate SAN.

Node Selector

This configuration describes a pod that has a node selector, disktype: ssd. This means that the pod will get scheduled on a node that has a disktype=ssd label.

See this documentation for more information.

# -- Node labels for pod assignment
nodeSelector:
  disktype: ssd

Tolerations

See this article explaining how to configure tolerations

# -- Toleration labels for pod assignment
tolerations:
- effect: NoExecute
  key: spot
  value: "true"
- effect: NoSchedule
  key: spot
  value: "true"

Node Affinity

See this article explaining how to configure affinity and anti-affinity rules

# -- Affinity settings for pod assignment
affinity:
  nodeAffinity:
    requiredDuringSchedulingIgnoredDuringExecution:
      nodeSelectorTerms:
      - matchExpressions:
        - key: topology.kubernetes.io/zone
          operator: In
          values:
          - antarctica-east1
          - antarctica-west1
    preferredDuringSchedulingIgnoredDuringExecution:
    - weight: 1
      preference:
        matchExpressions:
        - key: another-node-label-key
          operator: In
          values:
          - another-node-label-value

Generating Manifests

If you prefer using manifests over Helm, we recommend this approach. It allows you to track any modifications to the chart whenever a new version appears. You can apply a diff to your versioned files to identify what has been altered.
