⚠️ DEPRECATED: This operator is deprecated and will no longer receive updates with new features. Changes in this repository are only related to maintenance tasks. Users should migrate to alternative telemetry solutions.

Operator for the infra.watch smart gateway

Deployment to an existing cluster

Released Smart Gateway Operator

Use the OperatorHub in OpenShift to deploy from the Community catalog for a released version of Smart Gateway Operator.

Development Instance of Smart Gateway Operator in STF

The easiest way to get everything deployed is with the Service Telemetry Framework (STF). You can deploy a development version with the stf-run-ci role

This snippet will deploy the master (future main) branch across all repositories related to STF.

git clone https://github.com/infrawatch/service-telemetry-operator
oc new-project service-telemetry
oc patch configs.imageregistry.operator.openshift.io/cluster --patch '{"spec":{"defaultRoute":true}}' --type=merge
ansible-playbook build/run-ci.yaml -e __service_telemetry_events_enabled=false -e __service_telemetry_storage_ephemeral_enabled=true

Alternatively you can deploy the latest published artifacts. Currently this is not the recommended method.

ansible-playbook build/run-ci.yaml -e __local_build_enabled=false

Generate a bundle

Use the generate_bundle.sh script.

./build/generate_bundle.sh

Build and test against CodeReady Containers

NOTE: You'll need a Red Hat subscription to access CodeReady Containers. Access of the pull secret is available at https://cloud.redhat.com/openshift/install/crc/installer-provisioned. Upstream CodeReady development is available at https://github.com/code-ready/crc.

A procedure for testing in CodeReady Containers will be available soon.

• buildah
  • 1.14.0
• kubernetes
  • v1.16.2
• crc
  • crc version: 1.6.0+8ef676f
• oc
  • openshift-clients-4.2.0-201910041700
• operator-sdk
  • v0.15.2 (!0.13.0 which causes regressions via gen-csv command)

Set up CRC and buildah

Setup CRC and then login with the kubeadmin user.

$ crc setup
$ crc start --memory=32768
$ crc console --credentials

Install buildah via dnf.

sudo dnf install buildah -y

Login to CRC registry

REGISTRY=$(oc registry info)
TOKEN=$(oc whoami -t)
INTERNAL_REGISTRY=$(oc registry info --internal=true)
buildah login --tls-verify=false -u openshift -p "${TOKEN}" "${REGISTRY}"

Create working project (namespace)

Create a namespace for the application called service-telemetry.

oc new-project service-telemetry

Build the operator

buildah bud -f build/Dockerfile -t "${REGISTRY}/service-telemetry/smart-gateway-operator:latest" .
buildah push --tls-verify=false "${REGISTRY}/service-telemetry/smart-gateway-operator:latest"

Deploy with the newly built operator

Install required RBAC rules and service account.

oc apply \
    -f deploy/role_binding.yaml \
    -f deploy/role.yaml \
    -f deploy/service_account.yaml \
    -f deploy/operator_group.yaml

Pick a version from deploy/olm-catalog/smart-gateway-operator/ and run the following commands. Adjust version to what you want to test. We'll be using v1.0.0 as our example version.

CSV_VERSION=1.0.0
INTERNAL_REGISTRY=$(oc registry info --internal=true)
oc apply -f deploy/olm-catalog/smart-gateway-operator/${CSV_VERSION}/smartgateway.infra.watch_smartgateways_crd.yaml

oc create -f <(sed "\
    s|image: .\+/smart-gateway-operator:.\+$|image: ${INTERNAL_REGISTRY}/service-telemetry/smart-gateway-operator:latest|g;
    s|namespace: placeholder|namespace: service-telemetry|g"\
    "deploy/olm-catalog/smart-gateway-operator/${CSV_VERSION}/smart-gateway-operator.v${CSV_VERSION}.clusterserviceversion.yaml")

Validate that installation of the ClusterServiceVersion is progressing via the oc CLI console.

oc get csv --watch

If you see PHASE: Succeeded then your CSV has been properly imported and your Operator should be running locally. You can validate this by running oc get pods and looking for the smart-gateway-operator and that it is Running.

You can bring up the logs of the Smart Gateway Operator by running oc logs <<pod_name>> -c operator.

Simple Smart Gateway Deployment

To create a Smart Gateway, you'll need to connect it to a compatible AMQP 1.x message bus. For demonstration purposes we're going to use the Red Hat AMQ Interconnect Operator, create an AMQ Interconnect instance, then create a Smart Gateway instance that connects to it.

Create Message Bus Deployment

Subscribe to the AMQ Interconnect Operator and AMQ Certificate Manager. After subscribing create a new Interconnect object.

Create AMQ Interconnect Subscription

oc apply -f - <<EOF
apiVersion: operators.coreos.com/v1alpha1
kind: Subscription
metadata:
  name: amq7-interconnect-operator
  namespace: service-telemetry
spec:
  channel: 1.2.0
  installPlanApproval: Automatic
  name: amq7-interconnect-operator
  source: redhat-operators
  sourceNamespace: openshift-marketplace
EOF

You can check the status of the AMQ Interconnect ClusterServiceVersion installation with oc get csv. When complete you should see PHASE: Succeeded.

Create Interconnect Object

Create a simple Interconnect object to deploy AMQ Interconnect router.

apiVersion: interconnectedcloud.github.io/v1alpha1
kind: Interconnect
metadata:
  name: amq-interconnect
  namespace: smart-gateway
spec:
  addresses:
  - distribution: multicast
    prefix: collectd
  - distribution: multicast
    prefix: ceilometer
  deploymentPlan:
    livenessPort: 8888
    placement: AntiAffinity
    resources: {}
    role: interior
    size: 1
  edgeListeners:
  - expose: true
    port: 5671
    saslMechanisms: ANONYMOUS
    sslProfile: openstack
  interRouterListeners:
  - port: 55672
  listeners:
  - port: 5672
  sslProfiles:
  - generateCaCert: true
    generateCredentials: true
    name: openstack
  users: amq-interconnect-users

Validate that you see an AMQ Interconnect router come up with oc get pods.

Creating a Smart Gateway

Create a Smart Gateway deployment.

Create Smart Gateway Instance

oc apply -f - <<EOF
apiVersion: smartgateway.infra.watch/v2alpha1
kind: SmartGateway
metadata:
  name: cloud1-metrics
  namespace: service-telemetry
spec:
  amqpUrl: amq-interconnect:5672/collectd/telemetry
  debug: true
  prefetch: 15000
  serviceType: metrics
  size: 1
EOF
