Ansible Playbook for the OCI Arcade

The OCI Arcade with Kafka Streaming

I’m ever fine tuning this for the purpose of getting things done. For this I’m purposefully looking at the DevOps side of the picture. There are resources and a lifecycle that is better suited with Ansible or other CI/CD frameworks / pipelines.

I’ve extended the existing Oracle Resource Manager (ORM) automation. Have a look (here) about what I’ve done with ORM such that I used Ansible to do a couple of things.

Turning a Compartment into a ORM Stack

Effective first, then efficient and then elegant …

Peter Laurie – mate and mentor.

I’ve been doing some collaboration with @stantanev around a project and part of the contribution that I was doing was getting some stuff setup / configured and deployed into Oracle Cloud Infrastructure. This wasn’t a standard copy-and-paste scenario. I was building it up as we went. And then I was done … But it felt unfinished because I didn’t want to just leave it there. I wanted to share what I have without me getting sucked into other work standing up new environments (noting in the last article – I am lazy). And in the first instance, I only had dev (where I was working) and I needed to create a new one so people can start experiencing what we delivered (quickly).

What I invested in was using Oracle Resource Manager “ORM” to help me take what I built in Oracle Cloud Infrastructure and turn that into something that I could hand-over. Let’s have a look.

Automating with OCI Oracle Resource Manager

I use this because I’m lazy.

This is true. After doing something that is repetitive because either I’m testing or incrementally improving what is happen, I get frustrated. So, I automate. In this scenario, here I have an application that I’ve been working with a few people (like @stantanev), and as such spending a little bit of time automating the provisioning of the stack made sense. I value my time as I value other people’s time.

Oracle Resource Manager (ORM) is part of Oracle Cloud Infrastructure and is available in all tiers – Trials, Always Free Tier, Pay-As-You-Go or with Universal Credits. In short – EVERYONE gets it. The easiest way that I think of ORM, is that its a managed Terraform service within the Oracle Cloud Infrastructure environment. Let’s talk a look at it.

#DigitalDefence – A Tribute To The Teams

It was fantastic to see / hear / participate in the closing ceremony of the #DigitalDefence Hackathon 2020. If you want to check the whole ceremony including some of locknotes, check it out here.

#DigitalDefence Hackathon 2020 Closing Ceremony recorded by Hackmakers (https://hackmakers.com)

It was great to see who won but also from the judging perspective, who else was in the Top 11 (yes 11, not 10) where we worked with our executive team including Cherie Ryan, Vice President at Oracle and our Regional Managing Director of Australia and New Zealand to pick the winners.

#DigitalDefence Hackathon … The Why?

Head to https://hackmakers.com to register as a competitor or to showcase your project / product.

It’s almost 9 days before the event launches on the Friday night. Even before that, there are a series of workshops / webinars that we are hosting as part of the event in the days leading up to the event. Even then we are:

a/ Making sure that we have people, mentors, marketing, product managers, executives lined up to help where they can.
b/ Making sure that we have ideas, platforms, trials, programs, education material lined up to help where it’s feasible.
c/ Making sure that we help promote, advocate, market the event so those who would benefit would know about the event and attend.

All this effort for what outcome?

This says it all. And even though this is about #anomalydetection #deepfake #cybersecurity, much of this comes down to data – where the data can be sourced, how the data can be analysed, is the data reliable and can it be trusted.

Over the coming days leading up to the event – there will be plenty of chatter around it. Follow the event on LinkedIn. Some easy ways to follow are:

1/ Follow #DigitalDefence at https://www.linkedin.com/feed/hashtag/?keywords=digitaldefence
2/ Follow Hackmakers at https://www.linkedin.com/company/hackmakers
3/ Follow me at https://www.linkedin.com/in/lowe-jason/

I’ll be writing more about it here as we go and as new content is available. If you are interested to know or more if you want to join a team or showcase a project or product – head to the Hackmakers website https://hackmakers.com/ to learn more and register.

AUSOUG Connect 2018 – Talking Dev

ausoug-title-01.pngIn November 2018, I had the privilege to attend the Australian Oracle User Group national conference “#AUSOUG Connect” in Melbourne. My role was to have video interviews with as many of the speakers and exhibitors at the conference. Overall, 10 interviews over the course of the day, 90 mins of real footage, 34 short clips to share and plenty of hours reviewing and post-editing to capture the best parts.

Teaching How to Get Started with Oracle Container Engine for Kubernetes (OKE)

In a previous blog, I explained how to provision a Kubernetes cluster locally on your laptop (either as a single node with minikube or a multi-node using VirtualBox), as well as remotely in the Oracle Public Cloud IaaS. In this blog, I am going to show you how to get started with Oracle Container Engine for Kubernetes (OKE). OKE is a fully-managed, scalable, and highly available service that you can use to deploy your containerized applications to the cloud on Kubernetes.

Teaching How to Provision Oracle Integration Cloud (OIC) with Cloud Stack and Terraform

We have covered multiple blogs on how to use Terraform to help automate the provisioning of environments and treat your Infrastructure as Code. Until now, for PaaS stacks, we have used Terraform together with Oracle PaaS Service Manager (PSM) CLI. This gives us great flexibility to script our own tailored PaaS stacks the way we want them. However, with flexibility comes responsibility, and in this case, if we choose to use PSM CLI, it’s up to us to script the whole provisioning/decommission of components that make up the stack. As well as what to do if we encounter an error half-way through, so that we leave things consistently.

A simpler way to provision PaaS stacks is by making use of Oracle Cloud Stack, that treats all components of the stack as a single unit, where all sub-components are provisioned/decommissioned transparently for us. For example, Oracle Integration Cloud (OIC) stack, is made of Oracle DB Cloud Service (DBCS), Integration Cloud Service (ICS), Process Cloud Service (PCS), Visual Builder Cloud Service (VBCS), IaaS, storage, network, etc. If we use Oracle Cloud Stack to provision an environment, we only have to pass a YAML template with the configuration of the whole stack and then, Cloud Stack handles the rest. Pretty awesome huh?

Similarly, as we have done in the past, we are going to use a “Build Server”. This will be used as a platform to help us provision our PaaS stacks. When provisioning this “Build Server”, I will add all the tooling it requires as part of its bootstrap process. For this, I am using Vagrant + Terraform, so that I can also treat my “Build Server” as “infrastructure as code” and I can easily get rid of it, after I built my target PaaS stack.

This is a graphical view of what I will be doing in this blog to provision an OIC stack via Cloud Stack:

Teaching How to Get started with Kubernetes deploying a Hello World App

In a previous blog, I explained how to provision a new Kubernetes environment locally on physical or virtual machines, as well as remotely in the Oracle Public Cloud. In this workshop, I am going to show how to get started by deploying and running a Hello World NodeJS application into it.

There are a few moving parts involved in this exercise:

  • Using an Ubuntu Vagrant box, I’ll ask you to git clone a “Hello World NodeJS App”. It will come with its Dockerfile to be easily imaged/containerised.
  • Then, you will Docker build your app and push the image into Docker Hub.
  • Finally, I’ll ask you to go into your Kubernetes cluster, git clone a repo with a sample Pod definition and run it on your Kubernetes cluster.

Teaching How to quickly provision a Dev Kubernetes Environment locally or in Oracle Cloud

This time last year, people were excited talking about technologies such as Mesos or Docker Swarm to orchestrate their Docker containers. Now days (April 2018) almost everybody is talking about Kubernetes instead. This proves how quickly technology is moving, but also it shows that Kubernetes has been endorsed and backed up by the Cloud Giants, including AWS, Oracle, Azure, (obviously Google), etc.

At this point, I don’t see Kubernetes going anywhere in the coming years. On the contrary, I strongly believe that it is going to become the default way to dockerise environments, especially now that it is becoming a PaaS offering with different cloud providers, e.g. Oracle Containers. This is giving the extra push to easily operate in enterprise mission critical solutions, having the backup of a big Cloud Vendor.
