Create a remote container

In this exercise, you'll create a container in which to run the Lamp API in an Azure Functions project locally. Azure Functions requires a specific setup in order to work, including .NET Core, Azure Functions Core Tools and the Azure Functions extension. All of these things will be isolated in the container.

Exercise

• Add the Remote Development configuration files to the "start" project

• Include all of the dependencies to run an Azure Functions project

• Open the project in the container

• Run the API as a Serverless Function

Answer

• Open the Command Palette(Cmd/Ctrl + Shift + P)

• Select "Remote-Containers: Add Development Container Configuration Files"

Select the "start" project from the prompt

• Select the "Azure Functions & Node.js (latest LTS)

• VS Code will add a ".devcontainer" folder to the "start" project. Inside this folder are two files..

  • Dockerfile

  • devcontainer.json

• Open the Command Palette (Cmd/Ctrl + Shift + P)

• Select "Remote-Containers: Open Folder in Container"

• Find the "start" folder inside the "exercise-6-remote-containers" folder and select it

• VS Code will immediately begin to build a container. You will see that in the bottom panel.

• Once the container is built, VS Code will be connected to the project which is now running inside of a container

• Press F5 to start the Serverless Function project

• Browse to "localhost:7071/api/setColor" on your machine

  • Pass a query string variable "localhost:7071/api/setColor?color=blue"

• You will receive a response from the Serverless Function
