GIDS 2019: Developing Apps with Containers, Functions and Cloud Services

Editor's Notes

• #30: It’s incredibly easy to get started when using the az command line tool. Assuming you’ve created a resource group, it’s just: az aks create az aks install-cli az aks get-credentials (you might need --overwrite-existing here) That’s it – then you’re up and running and you can query the cluster via kubectl get nodes as you normally would with a Kubernetes cluster. Super simple.
• #43: Building on top of the FaaS programming model, Azure Functions keep all the mentioned features and extend your possibilities with additional capabilities that help to reduce your development time and boost productivity, while using best in class tools.

• #55: And that’s not all! Sure, Terraform plus AKS is a winning combo, but Team Azure is also involved in lots of super-cool k8s ecosystem open source. Take Helm, for example! Which is now a CNCF incubating project - we donated the IP. At this point I always feel like I need to have a content warning for YAML - if YAML upsets you, there will be so much YAML. And we need to manage all that YAML between all our environments and versions! We use helm in AKS, azure dev spaces, azure pipelines, azure devops - this isn’t a “drink our own champagne” story - these tools support us too!
• #56: Helm manages complexity, has easy updates, allows you to easily version and share, and allows for easy release rollback. So let’s go into more detail on each!
• #57: Draft is simple app development and deployment into any kubernetes cluster. Two simple commands is all it takes for developers to start working on container-based applications. Draft also detects the language your applications are written in and uses packs to generate a Dockerfile and Helm Chart based on that programming language.
• #94: Okay, so the new, exciting shiny! Check out cnab.io if you want to jump right in. CNAB: A spec for packaging distributed apps. CNABs facilitate the bundling, installing and managing of container-native apps — and their coupled services. Cloud Agnostic: A CNAB can be composed to utilize whatever infra or services you require - there’s no vendor lock in. Deliverable Apps CNABs can be used to easily deliver apps across teams, organizations and marketplaces - even shared offline. Signed & Secure A CNAB can be cryptographically signed, attested, and verified to ensure a trustworthy source. [building all this on brigade]
• #95: Duffle is a simple command line tool that interacts with Cloud-Native Application Bundles (CNABs) - helping you package and unpackage distributed apps for deployment on whatever cloud platforms and services you use. - duffle-bag is a GUI, too.
• #96: Okay, so that’s a lot. Porter makes using CNAB easier - it’s a declarative bundle builder. When we deploy to the cloud, most of us aren’t dealing with just a single cloud provider or toolchain. The simplest of applications today need nginx, Let’s Encrypt, persistent file storage, DNS, and somewhere in there is your application. One app is installed with Helm, another with the cloud provider’s cli and it’s all glued together with magic bash scripts. That is a lot to figure out! 😅 Porter is a cloud installer that helps you manage everything together in a single bundle, focusing on what you know best: your application. Mixins: classes with methods for use by other classes (while not relying on inheritance). We can describe actions using mixins.
