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:

$ make package
$ helm install mender ./mender-3.2.2.tgz

Introduction

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

Prerequisites

Kubernetes 1.12+
Helm 3.0-beta3+

External services required

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

mongodb
MinIO
NATS

Installing mongodb

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

$ helm repo add bitnami https://charts.bitnami.com/bitnami
$ helm repo update
$ helm install mongodb bitnami/mongodb --version 11.1.3 --set "image.tag=4.4.13-debian-10-r29" --set "auth.enabled=false"

Installing MinIO

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

$ helm repo add minio https://helm.min.io/
$ helm repo update
$ helm install minio minio/minio --version 8.0.10 --set "image.tag=RELEASE.2021-02-14T04-01-33Z" --set "accessKey=myaccesskey,secretKey=mysecretkey" --set "resources.requests.memory=128M"

Installing NATS

Follow instructions from https://nats-io.github.io/k8s using helm:

$ helm repo add nats https://nats-io.github.io/k8s/helm/charts/
$ helm repo update
$ helm install nats nats/nats --version 0.15.1 --set "nats.image=nats:2.7.4-alpine" --set "nats.jetstream.enabled=true"

Installing the Chart

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

$ helm install my-release -f values.yaml ./mender-3.2.2.tgz

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
