Mender

Mender is a robust and secure way to update all your software and deploy your IoT devices at scale with support for customization.

TL;DR;

Using helm:

helm install mender ./mender

Introduction

This chart bootstraps a Mender deployment on a Kubernetes cluster using the Helm package manager.

Prerequisites

  • Kubernetes 1.12+
  • Helm >= 3.7.0

External services required

This Helm chart does not install the following external services and dependencies which are required to run Mender:

  • MinIO

Installing mongodb

MongoDB is integrated as a sub-chart deployment: you can enable it with the following settings:

mongodb:
  enabled: true

# or via the --set argument:
--set="mongodb.enabled=true"

You can customize it by following the provider's specifications. It's recommended to use an external deployment in Production.

Installing MinIO

You can install MinIO using the official MinIO Helm chart using helm:

cat >minio-operator.yml <<EOF
tenants: {}
EOF

helm repo add minio https://operator.min.io/
helm repo update
helm install minio-operator minio/minio-operator --version 4.1.7 -f minio-operator.yml

export MINIO_ACCESS_KEY=$(pwgen 32 1)
export MINIO_SECRET_KEY=$(pwgen 32 1)

cat >minio.yml <<EOF
apiVersion: v1
kind: Secret
metadata:
  name: minio-creds-secret
type: Opaque
data:
  accesskey: $(echo -n $MINIO_ACCESS_KEY | base64)
  secretkey: $(echo -n $MINIO_SECRET_KEY | base64)
---
apiVersion: minio.min.io/v2
kind: Tenant
metadata:
  name: minio
  labels:
    app: minio
spec:
  image: minio/minio:RELEASE.2021-06-17T00-10-46Z
  credsSecret:
    name: minio-creds-secret
  pools:
    - servers: 2
      volumesPerServer: 2
      volumeClaimTemplate:
        metadata:
          name: data
        spec:
          accessModes:
            - ReadWriteOnce
          resources:
            requests:
              storage: 10Gi
          storageClassName: "standard"
  mountPath: /export
  requestAutoCert: false
EOF

kubectl apply -f minio.yml

Installing NATS

NATS is integrated as a sub-chart deployment: you can enable it with the following settings:

nats:
  enabled: true

# or via the --set argument:
--set="nats.enabled=true"

You can customize it by following the provider's specifications. It's recommended to use an external deployment in Production.

Installing the Chart

To install the chart with the release name my-release using helm:

helm install my-release -f values.yaml ./mender

The command deploys Mender on the Kubernetes cluster in the default configuration. The Parameters section lists the parameters that can be configured during installation.

Tip: List all releases using helm list

This is the minimum values.yaml file needed to install Mender:

global:
  image:
    username: <your_user>
    password: <your_password>
  url: https://mender.example.com

api_gateway:
  certs:
    cert: |-
      -----BEGIN CERTIFICATE-----
      MIIFcjCCBFq...
    key: |-
      -----BEGIN PRIVATE KEY-----
      MIIEvgIBADA...

device_auth:
  certs:
    key: |-
      -----BEGIN RSA PRIVATE KEY-----
      MIIEvgIBADA...

tenantadm:
  certs:
    key: |-
      -----BEGIN RSA PRIVATE KEY-----
      MIIEvgIBADA...

useradm:
  certs:
    key: |-
      -----BEGIN RSA PRIVATE KEY-----
      MIIEvgIBADA...

You can generate your cert and key for api-gareway using openssl:

openssl req -x509 -sha256 -nodes -days 3650 -newkey ec:<(openssl ecparam -name prime256v1) -keyout private.key -out certificate.crt -subj /CN="your.host.name"

You can generate the RSA private keys for device-auth, tenantadm and useradm using openssl:

openssl genpkey -algorithm RSA -out device_auth.key -pkeyopt rsa_keygen_bits:3072
openssl rsa -in device_auth.key -out device_auth_converted.key
mv device_auth_converted.key device_auth.key

Uninstalling the Chart

To uninstall/delete the my-release deployment:

helm delete my-release

The command removes all the Kubernetes components associated with the chart and deletes the release.

Create a tenant and a user from command line

Enterprise version

You can create a tenant from the command line of the tenantadm pod; the value printed is the newly generated tenant ID:

tenantadm create-org --name demo --username "admin@mender.io" --password "adminadmin" --plan enterprise
5dcd71624143b30050e63bed

You can create additional useres from the command line of the useradm pod:

useradm-enterprise create-user --username "demo@mender.io" --password "demodemo" --tenant-id "5dcd71624143b30050e63bed"
187b8101-4431-500f-88da-54709f51f2e6

Open Source version

If you are running the Open Source version of Mender, you won't have the tenantadm service. You can create users directly in the useradm pod:

useradm create-user --username "demo@mender.io" --password "demodemo"
187b8101-4431-500f-88da-54709f51f2e6

Test the service through the GUI

You can port-forward the mender-api-gateway Kubernetes service to verify the system is up and running:

kubectl port-forward service/mender-api-gateway 443:443
