Fastest way to Get started with Portworx Data Services.

TL;DR This is the process to get an EKS Cluster with Portworx installed with PDS installed and registered to your account in the PDS Control Plane. By following this you can use one command:

eksctl create cluster -f gitops-cluster.yaml

Wait about 22 minutes and you are ready to go with Amazon EKS, PX Enterprise and Portworx Data Services!


With big help form the amazing Chris Kennedy I would like to share how to quickly get a K8s cluster with Portworx Enterprise. To start read Chris’ blog post here:
https://portworx.com/blog/how-to-deploy-portworx-using-gitops-workflows/

Go back and follow it carefully, in this example I assume you fully have the above article working. Now that you are up to speed on using Flux to deploy Portworx.

Save this to a file called your EKS cluster specI called mine gitops-cluster.yaml
Get more on the using eksctl to create your cluster and what is required for Portworx here https://docs.portworx.com/install-portworx/cloud/aws/aws-eks/eksctl/eksctl-operator/


gitops:
  flux:
    gitProvider: github      # required. options are github, gitlab or git
    flags:                   # required. arbitrary map[string]string for all flux args.
    # these args are not controlled by eksctl. see https://fluxcd.io/docs/get-started/ for all available flags
      owner: "yourgithubusername"
      repository: "demo-cloud-ops"
      private: "true"
      branch: "main"
      namespace: "flux-system"
      path: "clusters/demo-cluster"

If you followed Chris’ instructions you will have a git repo with the needed cloned from his example. The file you need to pay attention to for PDS to install on bootstrap of your cluster:

portworx/pds/kustomization.yaml

apiVersion: kustomize.config.k8s.io/v1beta1
kind: Kustomization
namespace: pds-system
resources:
  - pds-helm-release.yaml
  - pds-helm-repo.yaml

portworx/pds/pds-helm-repo.yaml

apiVersion: source.toolkit.fluxcd.io/v1beta2
kind: HelmRepository
metadata:
  name: pds
  namespace: pds-system

portworx/pds/pds-helm-release.yaml

apiVersion: helm.toolkit.fluxcd.io/v2beta1
kind: HelmRelease
metadata:

  chart:
    spec:
      chart: pds-target
      sourceRef:
        kind: HelmRepository
        name: pds
        namespace: pds-system
      version: 1.5.0 #set to your current pds version
  values:
        tenantId: "inserter your pds tennant id"
        bearerToken: "insert pds bearer token"
        apiEndpoint: https://your api endpoint for pds

Notice the parts in bold you must get from the add target cluster wizard in the PDS control plane UI.

clusters/pds-flux-eksdemo/pds.yaml

apiVersion: kustomize.toolkit.fluxcd.io/v1beta2
kind: Kustomization
metadata:
  name: portworx-pds
  namespace: flux-system
spec:
  interval: 1m0s
  dependsOn: 
    - name: portworx-storagecluster
  sourceRef:
    kind: GitRepository
    name: flux-system
  path: ./portworx/pds
  prune: true
  wait: true

This file has an important part that makes the PDS install wait until after the storagecluster is finished.

The next few files in the repo are there to add the required namespaces for PDS and for a “pds-demo” namespace with the label pds.portworx.com/available: “true” This namespace label allows PDS to deploy data services to that namespace. All other namespaces are not seen by the PDS Deployment UI.

clusters/pds-flux-eksdemo/px-ns.yaml

apiVersion: kustomize.toolkit.fluxcd.io/v1beta2
kind: Kustomization
metadata:
  name: namespaces
  namespace: flux-system
spec:
  interval: 1m0s
  sourceRef:
    kind: GitRepository
    name: flux-system
  path: ./portworx/namespaces
  prune: true

portworx/namespaces/px-ns.yaml

kind: Namespace
apiVersion: v1
metadata:
  name: pds-system
---
kind: Namespace
apiVersion: v1
metadata:
  name: portworx
---
kind: Namespace
apiVersion: v1
metadata:
  name: pds-demo
  labels:
    pds.portworx.com/available: "true"

portworx/namespaces/kustomization.yaml

apiVersion: kustomize.config.k8s.io/v1beta1
kind: Kustomization
resources:
  - px-ns.yaml

Once you have your files edited you can install your EKS cluster from a file. That has the gitops settings set to your Github repo.

eksctl create cluster -r gitops-admin.yaml

You will wait probably 20 – 25 minutes depending on how many nodes you are using. The minimum is 3 for Portworx but if you plan on have lots of Data Services running you will need to choose a bigger EC2 size and more nodes.

Have a great afternoon,

Test all Kubeconfig Contexts

One day I woke up and had like 14 clusters in my Kubeconfig. I didn’t remember which ones did what or if the clusters even still existed.

kubectl config get-contexts -o name | xargs -I {} kubectl --context={} get nodes -o wide

So I cooked up this command to run through them all and make sure they actually responded. This works for me. If you have an alternative way please share in the comments.

Connecting your Application to Cassandra on PDS

Next up is a way to test Cassandra when deployed with PDS. I saved my python application to GitHub here: https://github.com/2vcps/py-cassandra

The key here is to deploy Cassandra via PDS then get the server connection names from PDS. Each step is explained in the repo. Go over there and fork or clone the repo or just use my settings. A quick summary though (it is really this easy).

  1. Deploy Cassandra to your Target in PDS.
  2. Edit the env-secret.yaml file to match your deployment.
  3. Apply the secret. kubectl -n namespace apply -f env-secret.yaml
  4. Apply the deployment. kubectl -n namespace apply -f worker.yaml
  5. Check the database in the Cassandra pod. kubectl -n namespace exec -it cas-pod — bash
  6. Use cqlsh to check the table the app creates.

That is it pretty easy and it creates a lot of records in the database. You could also scale it up in order to test connections from many sources. I hope this helps you quickly use PDS and if you have any updates or changes to me repo please submit a PR.

Testing Apache Kafka in Portworx Data Services

With the GA of Portworx Data Services I needed a way to connect some test applications with Apache Kafka. Kafka is one of the most asked for Data Services in PDS. Deploying Kafka is very easy with PDS but I wanted to show how it easy it was for a data team to connect their application to Kafka in PDS. I was able to find a kafka-python library, so I started working on a couple of things.

  1. A python script to create some kind of load on Kafka.
  2. Containerize it, so I can make it easy and repeatable.
  3. Create the kubernetes deployments so it is quick and easy.

This following github repo is the result of that project.
https://github.com/2vcps/py-kafka

See the repo for the steps on setting up the secret and deployments in K8s to use with your PDS Kafka, honestly it should work with any Kafka deployment where you have the connection service, username and password.

A quick demo of it all in action

Check out the youtube demo I did above to see it all in action.

Portworx Data Services GA: An Admins View, So easy you won’t believe it…

Portworx Data Services (PDS) the DBaaS platform built on the Portworx Enterprise platform is One Platform for All Databases. This SaaS platform can work with your platform in the Cloud or in your datacenter. Check out this demo of some of the Admin tasks available.

The good part other than add your DB consumers and your target Clusters to run workloads, the rest is configured for you. The power in the platform is you can change many settings but for the best practices are already put in place for you. Now you can have all databases with just one API and one UI.

You no longer need to learn an Operator or Custom resources for every different data service your Developers, Data Architects and DBA’s ask for. Also your data teams don’t learn K8s, They work with databases without having to every become platform exports. Just one API, One UI.
One Platform. All Databases.

Be Awesome with Neo4j Graph Database In Kubernetes

Graph DB solution Neo4j is popular with Data Scientists and Data Architects trying to make connections of the nodes and relationships. Neo4j is able to do memory management other in memory operations to allow for efficiency and performance. All of that data needs to eventual persist to a data management platform. This is why I was first asked about Neo4j.

Some cool nodes

There are Community and Enterprise Editions like most software solutions these days and the robust enterprise type functions land in the Enterprise Edition. Things like RBAC and much higher scale.

Neo4j provides a repo of Helm charts and some helpful documentation on running the Graph Database in Kubernetes. Unfortunately, the instructions stop short of many of the K8s flavors supported by the cloud and on premises solutions. Pre-provisioning cloud disks might be great for a point solution of a single app. Most of my interactions with the people running k8s in production are building Platform as a Service (PaaS) or Database as a Service (DBaaS). Nearly all at least want the option of building these solutions to be hybrid or multi cloud capable. Additionally, DR and Backup are requirements to run in any environment that values their data and staying in business.

Portworx in 20 seconds

Portworx is a data platform that allows stateful applications such as Neo4j to run on an Cloud, on Premises Hardware on any K8s Distribution. It was built from the very beginning to run as a container for containers. </end commercial>

In this blog post I want to enhance and clarify the documentation for the Neo4j helm chart so that you can easily run the community or Enterprise Editions in your K8s deployment.

As with any database Neo4j will benefit greatly from running the persistence on Flash. All of my testing was done with a Pure Storage FlashArray.

Step 1

Already have K8s and Portworx installed. I used Portworx 2.9.1.1 and Vanilla K8s 1.22. Also already have Helm installed.
Note: The helm chart was giving me trouble until I updated helm to version 3.8.x

Step 2

Add the Neo4j helm repo

helm repo add neo4j https://helm.neo4j.com/neo4j
helm repo update

Step 3

Create a neo4j storage class

kind: StorageClass
apiVersion: storage.k8s.io/v1
metadata:
  name: neo4j
provisioner: pxd.portworx.com
parameters:
  repl: "2"
  io_profile: db_remote
kubectl apply -f neo4j-storageclass.yaml

Verify the Storage Class is available

kubectl get sc

Step 4

Create your values.yaml for your install.

values-standalone.yaml
neo4j:
  resources:
    cpu: "0.5"
    memory: "2Gi"

  # Uncomment to set the initial password
  #password: "my-initial-password"

  # Uncomment to use enterprise edition
  #edition: "enterprise"
  #acceptLicenseAgreement: "yes"

volumes:
  data:
    mode: "dynamic"
    # Only used if mode is set to "dynamic"
    # Dynamic provisioning using the provided storageClass
    dynamic:
      storageClassName: "neo4j"
      accessModes:
        - ReadWriteOnce
      requests:
        storage: 100Gi

Cluster values.yaml

node[0-x]values-cluster.yaml

Why do I say 0-x? Well neo4j requires a helm release for each core cluster node (read more detail in the neo4j helm docs). Each file for now is the same. Note: neo4j is an in memory database. 2Gi ram is great for the lab, but for really analytics use I would hope to use much more memory.

neo4j:
  name: "my-cluster"
  resources:
    cpu: "0.5"
    memory: "2Gi"
  password: "my-password"
  acceptLicenseAgreement: "yes"

volumes:
  data:
    mode: "dynamic"
    # Only used if mode is set to "dynamic"
    # Dynamic provisioning using the provided storageClass
    dynamic:
      storageClassName: "neo4j"
      accessModes:
        - ReadWriteOnce
      requests:
        storage: 100Gi
Read Replica values

Create another helm yaml file here is rr1-values-cluster.yaml

neo4j:
  name: "my-cluster"
  resources:
    cpu: "0.5"
    memory: "2Gi"
  password: "my-password"
  acceptLicenseAgreement: "yes"

volumes:
  data:
    mode: "dynamic"
    # Only used if mode is set to "dynamic"
    # Dynamic provisioning using the provided storageClass
    dynamic:
      storageClassName: "neo4j"
      accessModes:
        - ReadWriteOnce
      requests:
        storage: 100Gi

Download all the values.yaml from GitHub

Step 5

Install Neo4j (stand alone)

Standalone

The docs say to run this:

helm install my-neo4j-release neo4j/neo4j-standalone -f my-neo4j.values-standalone.yaml

I do the following and I’ll explain why.

helm install -n neo4j-1 neo4j-1 neo4j/neo4j-standalone -f ./values-standalone.yaml --create-namespace

Cluster Install

For each cluster node values.yaml

helm install -n neo4j-cluster neo4j-cluster-3 neo4j/neo4j-cluster-core -f ./node1-values-cluster.yaml --create-namespace

You need a minimum of 3 core nodes to create a cluster. So you must run the helm install command 3 times for the neo4j-cluster-core helm chart.

Successful Cluster Creation

Install Read Replica

The cluster must be up and functioning to install the read replica.

helm install -n neo4j-cluster neo4j-cluster-rr1 neo4j/neo4j-cluster-read-replica -f ./rr1-values-cluster.yaml
Install the Loadbalancer

To access neo4j from an external source you should install the loadbalancer service. Run the following command in our example.

 helm install -n neo4j-cluster lb neo4j/neo4j-cluster-loadbalancer --set neo4j.name=my-cluster
Why the -n tag?

I provide the -n with a namespace and the –create-namespace tag because it allows me to install my helm release in this case neo4j-1 into its own namespace. Which helps with operations for DR, Backup and even lifecycle cleanup down the road. When installing a cluster all the helm releases must be in the same namesapce.

Start Graph Databasing!

As you can see there are plenty of tutorials to see how you may use Neo4j

PX Essentials for FA (2.9.0)! How to install it?

This week Portworx Enterprise 2.9.0 released with it comes support for K8s 1.22 and the new Essentials for FlashArray License. You can now have more nodes and capacity and as many clusters as you like. Previously you only got 5 nodes and a single cluster for PX Essentials. More info in the release notes:

https://docs.portworx.com/reference/release-notes/portworx/#2-9-0

How to install your PX License

  1. Install the prerequisites for connecting your worker nodes with either iSCSI or Fiber Channel. https://docs.portworx.com/cloud-references/auto-disk-provisioning/pure-flash-array/
  2. Go to https://central.portworx.com and start to generate the spec
  3. While creating the spec you will get the commands to run with kubectl to create the px-pure-secret. This secret takes the pure.json file and puts it in a place where the Portworx Installer will use it to provision it’s block devices from FlashArray. How to create the pure.json file? More info here: https://docs.portworx.com/cloud-references/auto-disk-provisioning/pure-flash-array/#deploy-portworx
  4. Apply the Operator and the Storage Cluster. Enjoy your new data platform for Kubernetes.
  5. When Portworx detects the drives are coming from a FlashArray the License is automatically set! Nothing special to do!

Watch the walkthrough

PX + FA = ❤️

First, the ability to use Portworx with FlashArray is not new with 2.9.0. What is new is the automatic Essentials license. Of course you would have benefits of upgrading Essentials to Enterprise to get DR, Autopilot and Migration. Why would you want to run Portworx on the FlashArray? The central storage platform from the FlashArray give all the benefits you are used to with Pure but to your stateful workloads. All Flash Performance. No disruptive upgrade everything. Evergreen. Dedupe and compression with no performance impact. Thin provisioning. Put it this way? The same platform you run baremetal and vm based business critical apps? Oracle, MS SQL?Shouldn’t it run your modernized cloud native versions of these applications? (Still can be containerized Oracle or SQL so don’t @ me.) Together with Portworx it just makes sense to be better together.

PX + FB = ❤️

Don’t get confused. While the PX Store layer needs block storage to run, FlashBlade and Portworx has already been supported as a Direct Attach target for a while now. You may even notice in the demo above my pure.json includes my FlashBlade. So go ahead use them all.

Get Ready for Portworx Data Services

Over a year a go we were working on the final parts of the acquisition of Portworx. I knew Portworx was going to change everything at Pure. I also expected it to take a while. I knew that we were going to see amazing new things built on this Cloud Native Data Platform. In the last year I have witnessed customers do just that with their own stateful workloads. Examples include banks, online gaming, SaaS providers, retail chains and many more.

What I also knew would come someday was Portworx Data Services would introduce all of us a way to have stateful workloads as a service. Database as a service, anywhere k8s can run, on any cloud. On Tanzu, AWS, Azure, Google, RedHat, Rancher and so many more. Your data managed but not locked into a proprietary platform. Managed in a way built for Cloud Native, Built for Kubernetes. It is also here way faster than I thought. A big thank you to our Engineering teams for the amazing work to make Portworx Data Services a real thing.

More than just a deployment tool

This is not just “deploy me a container” with a database. This is a managed experience with the day 2 operations built in. You can work on getting results from your data while PDS manages the performance, protection and availability of your solution wherever you want it to be. Not locked to specific cloud but anywhere that runs K8s.

But Doesn’t Operator XYZ do that?

Maybe. A little bit. Today’s developers expect to choose the tools they need to deliver their application. Not to be forced onto a single platform. This results in Database Administrators and DevOps teams supporting many different data services all with their own nuances. Some places have 10-15 different databases or data services (some of them are not really databases). Imagine having to support, the deployment and ongoing management of everyone of those, in most cases the with no extra time or resources. Normally you don’t get a new headcount every time a developer wants to use a new kind of data service.

Portworx Data Services lets you learn one API, one Interface and you get one vendor to support and manage the little things you don’t have time for, like Performance, High Availability and Disaster Recovery best practices. Making the data available in other sites or clouds for analytics or other use cases. Even Building that data into Dev-Test-QA workflows.

The early access program is starting now, we want your input so if you have use cases for multiple Cloud Native stateful workloads please find me at @jon_2vcps on the twitter.

Pure Storage Unveils Portworx Data Services

Portworx 2.8 with FlashArray and FlashBlade Getting Started

Getting Started with Portworx 2.8 and the FlashArray and FlashBlade

Last week Portworx 2.8 went GA, with it new support for Tanzu TKGs TKGm (We supported PKS/TKGi for a long time), but also Support for Cloud Drives for FlashArray and Direct Access for FlashBlade. It also simplified the installation of Portworx with Tanzu from this earlier version.

FlashArray Volumes for Portworx

Portworx will automate creating a storage pool from volumes provisioned from the FlashArray. This is done for your during the install, you may specify the size of the volumes in the spec generator at https://central.portworx.com

Process to install

NOTE as of 8/4/21: This feature is in Tech Preview (contact me if you want to run in Production)

  1. Create the px-pure-secret from the pure.json file
  2. Generate your Portworx Cluster spec from https://central.portworx.com
  3. Install the PX-Operator (command at the end of the spec generator).
  4. Install the Portworx Storage Cluster

  1. https://docs.portworx.com/reference/pure-json-reference/
    Also look that the pure.json reference in order to get the API key and token in a secret for you to use with Portworx. The installation of Portworx detects this Kubernetes secret and uses that information to provision drives from the array.
    Check out the youtube demo:
FlashArray and FlashBlade from Portworx

Sample pure.json

{
    "FlashArrays": [
        {
            "MgmtEndPoint": "<first-fa-management-endpoint>",
            "APIToken": "<first-fa-api-token>"
        },
        {
            "MgmtEndPoint": "<second-fa-management-endpoint>",
            "APIToken": "<second-fa-api-token>"
        }
    ],
    "FlashBlades": [
        {
            "MgmtEndPoint": "<fb-management-endpoint>",
            "APIToken": "<fb-api-token>",
            "NFSEndPoint": "<fb-nfs-endpoint>",
        },
        {
            "MgmtEndPoint": "<fb-management-endpoint>",
            "APIToken": "<fb-api-token>",
            "NFSEndPoint": "<fb-nfs-endpoint>",
        }
    ]
}
kubectl create secret generic px-pure-secret --namespace kube-system --from-file=pure.json

Remember the secret must be called px-pure-secret and be in the namespace that you install Portworx.

Select Pure FlashArray

2. Generate the spec for the Portworx Cluster.

3. Install the PX-Operator – I suggest using what you get from the Spec generator online or down to a local file.

kubectl apply -f pxoperator.yaml

4. Install the Storage Cluster

kubectl apply -f px-spec.yaml

For FlashBlade!

Also included in the pure.json is the API Token and IP information for my FlashBlade. Since the FlashBlade runs NFS the K8s node mounts it directly. We call with Direct Attach and allows you to leverage your FlashBlade for data that may exist outside of the PX-Cluster. Watch the demo to see it in action. Create a StorageClass for FlashBlade and a PVC using that class. Portworx automates the rest.

Setting up Portworx on a Tanzu Kubernetes Grid aka TKG Cluster

First, this process works today on clusters made with the TKG tool that does not use the embedded management cluster. For clarity I call those clusters TKC or TKC Guest Clusters. The run as VM’s. You just can’t add block devices outside of the Cloud Native Storage (VMware’s CSI Driver). At least I couldn’t.

Now TKG deploys using a Photon 3.0 template. When I wrote this blog and recorded the demo the current latest version is TKG 1.2.1 and the k8s template is 1.19.3-vmware.

Check the release notes here: https://docs.portworx.com/reference/release-notes/portworx/#improvements-4

First generate base64 encoded versions of your user and password to vCenter.

# Update the following items in the Secret template below to match your environment:

VSPHERE_USER: Use output of printf <vcenter-server-user> | base64
VSPHERE_PASSWORD: Use output of printf <vcenter-server-password> | base64

The vsphere-secret.yaml save this to a file with your own user and password to vCenter (from above).


apiVersion: v1
kind: Secret
metadata:
  name: px-vsphere-secret
  namespace: kube-system
type: Opaque
data:
  VSPHERE_USER: YWRtaW5pc3RyYXRvckB2c3BoZXJlLmxvY2Fs
  VSPHERE_PASSWORD: cHgxLjMuMEZUVw==


kubectl apply the above spec after you update the above template with your user and password.

Follow these steps:

# create a new TKG cluster
tkg create cluster tkg-portworx-cluster -p dev -w 3 --vsphere-controlplane-endpoint-ip 10.21.x.x 

# Get the credentials for your config
tkg get credentials tkg-portworx-cluster

# Apply the secret and the operator for Portworx
kubectl apply -f vsphere-secret.yaml
kubectl apply -f 'https://install.portworx.com/2.6?comp=pxoperator'

#generate your spec first, you get this from generating a spec at https://central.portworx.com
kubectl apply -f tkg-px.yaml 

# Wait till it all comes up.
watch kubectl get pod -n kube-system

# Check pxctl status
PX_POD=$(kubectl get pods -l name=portworx -n kube-system -o jsonpath='{.items[0].metadata.name}')
kubectl exec $PX_POD -n kube-system -- /opt/pwx/bin/pxctl status

You can now create your own or use the premade storageClass

kubectl get sc

Now Deploy Kube-Quake

The example.yaml is from my fork of the kube-quake repo on github where I redirected the data to be on a persistent volume.
