To create the root and intermediate CA certificates run:

step ca init \
    --deployment-type standalone \
    --name MqttAppSamplesCA \
    --dns localhost \
    --address 127.0.0.1:443 \
    --provisioner MqttAppSamplesCAProvisioner

update password.txt with password provided

Modify az.env

source az.env

az account set -s $sub_id
az resource create --id $res_id --is-full-object --properties '{
  "properties": {
    "isZoneRedundant": true,
    "topicsConfiguration": {
      "inputSchema": "CloudEventSchemaV1_0"
    },
    "topicSpacesConfiguration": {
      "state": "Enabled"
    }
  },
  "location": "westus2"
}'

Register the certificate to authenticate client certificates (usually the intermediate)

source az.env

capem=`cat ~/.step/certs/intermediate_ca.crt | tr -d "\n"`

az resource create \
  --id "$res_id/caCertificates/Intermediate01" \
  --properties "{\"encodedCertificate\" : \"$capem\"}"

bash onboard-device.sh {id}
