Download as PPTX, PDF1 like708 views
The document discusses Azure Kubernetes Services (AKS) and Visual Studio Connected Environments (VSCE). It provides an overview of AKS and how to create an AKS cluster. It then discusses the current CI/CD process and how VSCE can improve the developer experience by allowing developers to run and debug code directly in an AKS cluster. It outlines the main VSCE commands and provides an example end-to-end scenario of using VSCE to debug code in a Kubernetes cluster directly from Visual Studio Code.

- 9. @Azuretar Current CI/CD Process Application Git Repo Helm Image layers Helm as your Package Management
- 10. @Azuretar Visual Studio Connected Environments VSCE
- 11. @Azuretar Developer Experience • Run or debug code prior to committing in a production-like development environment running in Azure • Work with real upstream and downstream dependencies instead of mocks or simulators • Use a shared team environment with isolated spaces to avoid complex setup and enable live, ongoing discovery of integration issues
- 12. @Azuretar VSCE Main Commands • vsce init - prepares a directory of source code for connected development o VSCE.yaml o Helm Charts o Dockerfile • vsce up - starts a connected development session against a target workload • vsce exec - runs a one-off command inside an existing target workload
- 13. @Azuretar Microsoft Confidential An end-to-end scenario frontend mainline repl mainline repl shayne “mainline” namespace “shayne” namespace Kubernetes Cluster VSCE services vsce “vsce” namespace Azure File Service Client Azure vsce “up” Init container builds the Docker image Transparent proxy manages s2s calls and traces calls helm install volume mounted source code POST /api/execute HTTP/1.1 Host: frontend vsce-space: shayne Content-Length: 123 <content> 10.2.3.4 10.5.6.7 Client synchronizes code to Azure File Share Helm chart is installed with instrumentation Consider a call to frontend then to repl: - https://shayne-frontend-env.vsce.io - DNS resolves to mainline repl - Proxy notices “vsce-space: shayne” - Retargets to IP of “repl.shayne” - Proxy reports traces back to client VSCE Ingress nginx Sets vsce-space: shayne
