Installing Anypoint Platform PCE on OpenShift

Before installing Anypoint Platform Private Cloud Edition (Anypoint Platform PCE) on OpenShift configure Security Context Constraints (SCC) to grant the required permissions for pods and create roles for Prometheus, allowing it to collect metrics from the services. After these configurations are complete, proceed with installing Anypoint Platform PCE.

You must have an operational OpenShift cluster prior to installing Anypoint Platform PCE. If you do not have one set up, refer to the OpenShift documentation for setup instructions.

Contact MuleSoft Professional Services to perform the installation of Anypoint Platform PCE.

Configure the Openshift Environment

To configure the OpenShift Environment, configure Security Context Constraints (SCC) and roles for Prometheus.

Configure Security Context Constraints (SCC)

The following snippet contains the SCC configuration:

Save this file as openshift-scc.yaml and apply it to the OpenShift cluster:

oc apply -f openshift-scc.yaml

Configure Roles for Prometheus

Prometheus requires specific roles to collect metrics from Anypoint Platform PCE services. The following snippet provides the necessary roles configuration:

apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRole
metadata:
  name: pce-prometheus
rules:
  - apiGroups:
      - ""
    resources:
      - endpoints
      - pods
      - services
      - nodes
      - secrets
    verbs:
      - get
      - list
      - watch
---
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: pce-prometheus
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: pce-prometheus
subjects:
  - kind: ServiceAccount
    name: prometheus-k8s
    namespace: openshift-monitoring

Save this file as openshift-monitoring.yaml and apply it to the OpenShift cluster:

oc apply -f openshift-monitoring.yaml

Install Anypoint Platform PCE on OpenShift

The following snippet provides an example installation manifest for deploying Anypoint Platform PCE on an OpenShift cluster:

containerRegistry:
  endpoint: registry.pce.example.com
  username: username
  password: password
  certificate: ''
  subproject: example
  tlsSkipVerify: true
postInstallConfiguration:
  platformDNS: anypoint.pce.example.com
  fileSystemDNS: fs.pce.example.com
  firstUserAccount:
    organizationName: Example Org
    username: username
    email: username@mulesoft.com
    password: password
  platformCertificate: cert.pem
  platformCertificateKey: key.pem
amvInstallConfiguration:
  enabled: false
storageConfiguration:
  pceobjectstore:
    type: persistentVolumeClaim
    storageClass: example-csi
  stolon:
    type: persistentVolumeClaim
    storageClass: example-csi
monitoringAppConfiguration:
  monitoringStackEnabled: false
  grafana:
    enabled: true
    values: |
      datasources:
        datasources.yaml:
          apiVersion: 1
          datasources:
          - name: Prometheus
            type: prometheus
            url: https://prometheus-k8s.openshift-monitoring.svc:9091
            access: proxy
            isDefault: true
            jsonData:
              tlsSkipVerify: true
              httpHeaderName1: 'Authorization'
            secureJsonData:
              httpHeaderValue1: 'Bearer <Token>'

Note the monitoringAppConfiguration section in the snippet. This section disables the monitoring stack for Anypoint Platform PCE and enables only the Grafana application. It is recommended to disable the monitoring stack because OpenShift includes Prometheus by default. Enable Grafana and configure its datasource to connect to Prometheus.

To obtain the token for connecting to Prometheus, run this command:

oc create token prometheus-k8s -n openshift-monitoring --duration=87600h

After completing the installation, run the following commands to allow Prometheus in OpenShift to collect metrics from platform services:

oc label namespace default openshift.io/cluster-monitoring="true" --overwrite
oc label namespace pce openshift.io/cluster-monitoring="true" --overwrite
