What will you see today - We will ”install” a cloud-native application which consists of - Some cloud infrastructure automated with Terraform - Dependencies being deployed to Kubernetes using Helm - A containerized application, being deployed to Kubernetes as a helm chart Preview

What we will cover today • Introduction • What is CNAB • Why should one use it • What is Porter • Adopting the Porter workflow Talking Points

Why are we talking about that • Distributed (cloud-based or cloud-native) apps consist of many artifacts • Infrastructure • Application binaries (packages, containers, functions) • Related services • Configuration Data (sensitive and non-sensitive) • Rather complex toolchains are used to manage and interact with them Introduction

Why are we talking about that Build & test the app Build and push Docker image(s) Provision cloud infrastructure Configure cloud infrastructure Deploy dependencies Deploy application Introduction P

Why are we talking about that Introduction az (Azure CLI) Bash (Shell Scripts) PowerShell (PowerShell Scripts) terraform (Terraform CLI) tfenv (Terraform Version Manager) nvm (Node Version Manager) npm (Node Package Manager) dotnet (.NET CLI) docker (Docker CLI) kubectl (Kubernetes CLI) helm (Helm CLI) CMD (Batch Files) azcopy (Azure Storage Copy) bicep (Project Bicep CLI)

https://cnab.io/ - Cloud-Native Application Bundles (CNAB) - Specifies how distributed apps are packaged, installed, mutated, and destroyed - CNAB is cloud agnostic - CNAB artifacts are - easy to share / consume - signed to verify integrity - consumed and stored in trusted locations What is CNAB

Anatomy of a CNAB bundle What is CNAB Application Image(s) Invocation Image Bundle Descriptor Cloud Native Application Bundle

Application Image(s) • Your good old application image • (Docker) Container Image • Containerized applications are typical use-case • But not mandatory What is CNAB

Invocation Image • Technically it is a container image • The invocation image contains all required tools • Desired tool configuration applied • Desired version is installed • It contains all templates, manifests, metadata, and configuration • THIS IS THE CLOUD-INSTALLER What is CNAB Source https://media.giphy.com/media/mXnO9IiWWarkI/source.gif

Bundle Descriptor • JSON document containing essential information about the CNAB bundle • Application image(s) with its/their digests • Invocation image with its digests • Definitions of inputs and outputs • Can be singed What is CNAB

CNAB Distribution Channels • Bundles are OCI compliant aritfacts • The can be stored in OCI Registries • For example a Docker Registry such as Azure Container Registry (ACR) What is CNAB

What we will cover today • Introduction • What is CNAB • Why should one use it • What is Porter • Adopting the Porter workflow Talking Points

• Keep using the tools you know and love • Abstract away the complexities with a single command • Eleminate truck factor • Establish trust • by signing bundles • by distributing your applications using trusted channels Why should one use it

• Simplifies cloud-native application lifecycle • Everything becomes version-controlled • Installing, and upgrading cloud-native applications becomes • atomic • easy Why should one use it

https://porter.sh/ - Open-source CNAB implementation - Establishes patterns to improve productivity - Parameters - Outputs - Credentials - Mixins - Makes authoring CNAB bundles easy and offers a single CLI What is Porter

The Porter Manifest - Single YAML Manifest provides all capabilities - Porter creates a CNAB bundle from the manifest - Required tools (mixins) will be added to the invocation image by Porter - Dockerfile template can be fully customized - if required What is Porter

Porter mixins - Porter mixins are managed using the porter mixin commands - Available mixins - az, aws, gcloud - exec - terraform - Kubernetes, helm2, helm3 What is Porter

What happens where Porter Interactions local machine Invocation image destination Parameters and Credentials Actions and Steps

What was the outcome of the poll

Demo Time § Provision Azure Resource to deal with Terraform state correctly § Use Terraform to spin-up the application platform (AKS) § Install 3rd party dependencies in the cluster (NGINX Ingress) § Deploy the application (containerized .NET API) in the cluster Adopting the Porter workflow
