    OpenShift v4

    Table of Contents

    OpenShift v4

    Prisma Cloud Console is deployed as a Deployment, which ensures it’s always running. The Prisma Cloud Console and Defender container images can be stored either in the internal OpenShift registry or your own Docker v2 compliant registry. Alternatively, you can configure your deployments to pull images from Prisma Cloud’s cloud registry.

    Preflight checklist

    To ensure that your installation on supported versions of OpenShift v4.x goes smoothly, work through the following checklist and validate that all requirements are met.

    Minimum system requirements

    Validate that the components in your environment (nodes, host operating systems, orchestrator) meet the specs in System requirements.
    For OpenShift installs, we recommend using the overlay or overlay2 storage drivers due to a known issue in RHEL. For more information, see https://bugzilla.redhat.com/show_bug.cgi?id=1518519.

    Permissions

    Validate that you have permission to:
    • Push to a private docker registry. For most OpenShift setups, the registry runs inside the cluster as a service. You must be able to authenticate with your registry with docker login.
    • Pull images from your registry. This might require the creation of a docker-registry secret.
    • Have the correct role bindings to pull and push to the registry. For more information, see Accessing the Registry.
    • Create and delete projects in your cluster. For OpenShift installations, a project is created when you run oc new-project.
    • Run oc create commands.

    Internal cluster network communication

    TCP: 8083, 8084

    External cluster network communication

    TCP: 443
    The Prisma Cloud Console connects to the Prisma Cloud Intelligence Stream (https://intelligence.twistlock.com) on TCP port 443 for vulnerability updates. If your Console is unable to contact the Prisma Cloud Intelligence Stream, follow the guidance for offline environments.

    Download the Prisma Cloud software

    Download the latest Prisma Cloud release to any system where the OpenShift oc client is installed.
    1. Go to Releases, and copy the link to current recommended release.
    2. Download the release tarball to your cluster controller.
      $ wget <LINK_TO_CURRENT_RECOMMENDED_RELEASE_LINK>
    3. Unpack the release tarball.
      $ mkdir twistlock
$ tar xvzf twistlock_<VERSION>.tar.gz -C twistlock/
    4. Use twistcli to install the Prisma Cloud Console and Defenders. The twistcli utility is included with every release. After completing this procedure, both Prisma Cloud Console and Prisma Cloud Defenders will be running in your OpenShift cluster.

    Create an OpenShift project for Prisma Cloud

    Create a project named twistlock.
    1. Login to the OpenShift cluster and create the twistlock project:
      $ oc new-project twistlock

    (Optional) Push the Prisma Cloud images to a private registry

    When Prisma Cloud is deployed to your cluster, the images are retrieved from a registry. You have a number of options for storing the Prisma Cloud Console and Defender images:
    • OpenShift internal registry.
    • Private Docker v2 registry. You must create a docker-secret to authenticate with the registry.
    Alternatively, you can pull the images from the Prisma Cloud cloud registry at deployment time. Your cluster nodes must be able to connect to the Prisma Cloud cloud registry (registry-auth.twistlock.com) with TLS on TCP port 443.
    This guides shows you how to use both the OpenShift internal registry and the Prisma Cloud cloud registry. If you’re going to use the Prisma Cloud cloud registry, you can skip this section. Otherwise, this procedure shows you how to pull, tag, and upload the Prisma Cloud images to the OpenShift internal registry’s twistlock imageStream.
    1. Determine the endpoint for your OpenShift internal registry. Use either the internal registry’s service name or cluster IP.
      $ oc get svc -n default
NAME               TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)       AGE
docker-registry    ClusterIP   172.30.163.181   <none>        5000/TCP      88d
    2. Pull the images from the Prisma Cloud cloud registry using your access token. The major, minor, and patch numerals in the <VERSION> string are separated with an underscore. For example, 18.11.128 would be 18_11_128.
        $ docker pull \
    registry-auth.twistlock.com/tw_<ACCESS_TOKEN>/twistlock/defender:defender_<VERSION>

  $ docker pull \
    registry-auth.twistlock.com/tw_<ACCESS_TOKEN>/twistlock/console:console_<VERSION>
    3. Tag the images for the OpenShift internal registry.
      $ docker tag \
  registry-auth.twistlock.com/tw_<ACCESS_TOKEN>/twistlock/defender:defender_<VERSION> \
  172.30.163.181:5000/twistlock/private:defender_<VERSION>

$ docker tag \
  registry-auth.twistlock.com/tw_<ACCESS_TOKEN>/twistlock/console:console_<VERSION> \
  172.30.163.181:5000/twistlock/private:console_<VERSION>
    4. Push the images to the twistlock project’s imageStream.
        $ docker push 172.30.163.181:5000/twistlock/private:defender_<VERSION>
  $ docker push 172.30.163.181:5000/twistlock/private:console_<VERSION>

    Install Console

    Use the twistcli tool to generate YAML files or a Helm chart for Prisma Cloud Compute Console. The twistcli tool is bundled with the release tarball. There are versions for Linux, macOS, and Windows.
    The twistcli tool generates YAML files or helm charts for a Deployment and other service configurations, such as a PersistentVolumeClaim, SecurityContextConstraints, and so on. Run the twistcli command with the --help flag for additional details about the command and supported flags.
    You can optionally customize twistlock.cfg to enable additional features. Then run twistcli from the root of the extracted release tarball.
    Prisma Cloud Console uses a PersistentVolumeClaim to store data. There are two ways to provision storage for Console:
    • Dynamic provisioning:
       Allocate storage for Console on-demand at deployment time. When generating the Console deployment YAML files or helm chart with twistcli, specify the name of the storage class with the --storage-class flag. Most customers use dynamic provisioning.
    • Manual provisioning:
       Pre-provision a persistent volume for Console, then specify its label when generating the Console deployment YAML files. OpenShift uses NFS mounts for the backend infrastructure components (e.g. registry, logging, etc.). The NFS server is typically one of the master nodes. Guidance for creating an NFS backed PersistentVolume can be found here. Also see Appendix: NFS PersistentVolume example.

    Option #1: Deploy with YAML files

    Deploy Prisma Cloud Compute Console with YAML files.
    1. Generate a deployment YAML file for Console. A number of command variations are provided. Use them as a basis for constructing your own working command.
      1. Prisma Cloud Console + dynamically provisioned PersistentVolume + image pulled from the OpenShift internal registry.*
          $ <PLATFORM>/twistcli console export openshift \
    --storage-class "<STORAGE-CLASS-NAME>" \
    --image-name "172.30.163.181:5000/twistlock/private:console_<VERSION>" \
    --service-type "ClusterIP"
      2. Prisma Cloud Console + manually provisioned PersistentVolume + image pulled from the OpenShift internal registry.
         Using the NFS backed PersistentVolume described in Appendix: NFS PersistentVolume example, pass the label to the --persistent-volume-labels flag to specify the PersistentVolume to which the PersistentVolumeClaim will bind.
          $ <PLATFORM>/twistcli console export openshift \
    --persistent-volume-labels "app-volume=twistlock-console" \
    --image-name "172.30.163.181:5000/twistlock/private:console_<VERSION>" \
    --service-type "ClusterIP"
      3. Prisma Cloud Console + manually provisioned PersistentVolume + image pulled from the Prisma Cloud cloud registry.
         If you omit the --image-name flag, the Prisma Cloud cloud registry is used by default, and you are prompted for your access token.
          $ <PLATFORM>/twistcli console export openshift \
    --persistent-volume-labels "app-volume=twistlock-console" \
    --service-type "ClusterIP"
    2. Deploy Console.
        $ oc create -f ./twistlock_console.yaml
      You can safely ignore the error that says the twistlock project already exists.

    Option #2: Deploy with Helm chart

    Deploy Prisma Cloud Compute Console with a Helm chart.
    Prisma Cloud Console Helm charts fail to install on OpenShift 4 clusters due to a Helm bug. If you generate a Helm chart, and try to install it in an OpenShift 4 cluster, you’ll get the following error:
      Error: unable to recognize "": no matches for kind "SecurityContextConstraints" in version "v1"
    To work around the issue, you’ll need to manually modify the generated Helm chart.
    1. Generate a deployment helm chart for Console. A number of command variations are provided. Use them as a basis for constructing your own working command.
      1. Prisma Cloud Console + dynamically provisioned PersistentVolume + image pulled from the OpenShift internal registry.
          $ <PLATFORM>/twistcli console export openshift \
    --storage-class "<STORAGE-CLASS-NAME>" \
    --image-name "172.30.163.181:5000/twistlock/private:console_<VERSION>" \
    --service-type "ClusterIP" \
    --helm
      2. Prisma Cloud Console + manually provisioned PersistentVolume + image pulled from the OpenShift internal registry.
         Using the NFS backed PersistentVolume described in Appendix: NFS PersistentVolume example, pass the label to the --persistent-volume-labels flag to specify the PersistentVolume to which the PersistentVolumeClaim will bind.
          $ <PLATFORM>/twistcli console export openshift \
    --persistent-volume-labels "app-volume=twistlock-console" \
    --image-name "172.30.163.181:5000/twistlock/private:console_<VERSION>" \
    --service-type "ClusterIP" \
    --helm
      3. Prisma Cloud Console + manually provisioned PersistentVolume + image pulled from the Prisma Cloud cloud registry.
         If you omit the --image-name flag, the Prisma Cloud cloud registry is used by default, and you are prompted for your access token.
          $ <PLATFORM>/twistcli console export openshift \
    --persistent-volume-labels "app-volume=twistlock-console" \
    --service-type "ClusterIP" \
    --helm
    2. Unpack the chart into a temporary directory.
        $ mkdir helm-console
  $ tar xvzf twistlock-console-helm.tar.gz -C helm-console/
    4. {{- if .Values.openshift }}
apiVersion: security.openshift.io/v1
kind: SecurityContextConstraints
metadata:
  name: twistlock-console
...
    5. Repack the Helm chart
        $ cd helm-console/
  $ tar cvzf twistlock-console-helm.tar.gz twistlock-console/
    6. Install the updated Helm chart.
        $ helm install --namespace=twistlock -g twistlock-console-helm.tar.gz

    Create an external route to Console

    Create an external route to Console so that you can access the web UI and API.
    1. From the OpenShift web interface, go to the twistlock project.
    2. Go to
      Application > Routes
      .
    3. Select
      Create Route
      .
    4. Enter a name for the route, such as
      twistlock-console
      .
    5. Hostname = URL used to access the Console, e.g. twistlock-console.apps.ose.example.com
    6. Path =
      /
    7. Service =
      twistlock-console
    8. Target Port = 8083 → 8083
    9. Select the
      Security > Secure Route
       radio button.
    10. TLS Termination = Passthrough (if using 8083)
      If you plan to issue a custom certificate for Console TLS communication that is trusted and will allow the TLS establishment with the Prisma Cloud Console, then Select Passthrough TLS for TCP port 8083.
    11. Insecure Traffic =
      Redirect
    12. Click
      Create
      .

    Create an external route to Console for external Defenders

    If you are planning to deploy Defenders to another cluster and report to this Console, you will need to create an additional external route to Console so that the Defenders can access the Console. You need to expose the Prisma Cloud-Console service’s TCP port 8084 as external OpenShift routes. Each route will be an unique, fully qualified domain name.
    1. From the OpenShift web interface, go to the twistlock project.
    2. Go to
      Application > Routes
      .
    3. Select
      Create Route
      .
    4. Enter a name for the route, such as
      twistlock-console-8084
      .
    5. Hostname = URL used to access the Console, using a different hostname, e.g. twistlock-console-8084.apps.ose.example.com
    6. Path =
      /
    7. Service =
      twistlock-console
    8. Target Port = 8084 → 8084
    9. Select the
      Security > Secure Route
       radio button.
    10. TLS Termination = Passthrough (if using 8084)
      The Defender to Console communication is a mutual TLS secure websocket session. This communication cannot be intercepted.
    11. Insecure Traffic =
      Redirect
    12. Click
      Create
      .

    Configure Console

    Create your first admin user, enter your license key, and configure Console’s certificate so that Defenders can establish a secure connection to it.
    1. In a web browser, navigate to the external route you configured for Console, e.g. https://twistlock-console.apps.ose.example.com.
    2. Create your first admin account.
    3. Enter your license key.
    4. Add a SubjectAlternativeName to Console’s certificate to allow Defenders to establish a secure connection with Console.
      Use either Console’s service name, twistlock-console or twistlock-console.twistlock.svc, or Console’s cluster IP.
      Additionally, if a route for external Defenders was created, add that one to the SAN list too: twistlock-console-8084.apps.ose.example.com
        $ oc get svc -n twistlock
  NAME                TYPE           CLUSTER-IP     EXTERNAL-IP                 PORT(S)
  twistlock-console   LoadBalancer   172.30.41.62   172.29.61.32,172.29.61.32   8084:3184...
      1. Go to
        Manage > Defenders > Names
        .
      2. Click
        Add SAN
         and enter Console’s service name.
      3. Click
        Add SAN
         and enter Console’s cluster IP.

    Appendix: NFS PersistentVolume example

    Create an NFS mount for the Prisma Cloud Console’s PV on the host that serves the NFS mounts.
    1. mkdir /opt/twistlock_console
    2. Check selinux:
      sestatus
    3. chcon -R -t svirt_sandbox_file_t -l s0 /opt/twistlock_console
    4. sudo chown nfsnobody /opt/twistlock_console
    5. sudo chgrp nfsnobody /opt/twistlock_console
    6. Check perms with:
      ls -lZ /opt/twistlock_console
       (drwxr-xr-x. nfsnobody nfsnobody system_u:object_r:svirt_sandbox_file_t:s0)
    7. Create
      /etc/exports.d/twistlock.exports
    8. In the
      /etc/exports.d/twistlock.exports
       add in line
      /opt/twistlock_console *(rw,root_squash)
    9. Restart nfs mount
      sudo exportfs -ra
    10. Confirm with
      showmount -e
    11. Get the IP address of the Master node that will be used in the PV (eth0, openshift uses 172. for node to node communication). Make sure TCP 2049 (NFS) is allowed between nodes.
    12. Create a PersistentVolume for Prisma Cloud Console.
      The following example uses a label for the PersistentVolume and the volume and claim pre-binding features. The PersistentVolumeClaim uses the app-volume: twistlock-console label to bind to the PV. The volume and claim pre-binding claimref ensures that the PersistentVolume is not claimed by another PersistentVolumeClaim before Prisma Cloud Console is deployed.
      apiVersion: v1
kind: PersistentVolume
metadata:
 name: twistlock
 labels:
  app-volume: twistlock-console
storageClassName: standard
spec:
  capacity:
   storage: 100Gi
  accessModes:
  - ReadWriteOnce
  nfs:
   path: /opt/twistlock_console
   server: 172.31.4.59
persistentVolumeReclaimPolicy: Retain
claimRef:
  name: twistlock-console
  namespace: twistlock

    Appendix: Implementing SAML federation with a Prisma Cloud Console inside an OpenShift cluster

    When federating Prisma Cloud Console that is accessed through an OpenShift external route with a SAML v2.0 Identity Provider (IdP), the SAML authentication request’s AssertionConsumerServiceURL value must be modified. Prisma Cloud automatically generates the AssertionConsumerServiceURL value sent in a SAML authentication request based on Console’s configuration. When Console is accessed through an OpenShift external route, the URL for Console’s API endpoint is most likely not the same as the automatically generated AssertionConsumerServiceURL. Therefore, you must configure the AssertionConsumerServiceURL value that Prisma Cloud sends in the SAML authentication request.
    1. Log into Prisma Cloud Console.
    2. Go to
      Manage > Authentication > SAML
      .
    3. In
      Console URL
      , define the AssertionConsumerServiceURL.
