Visual Studio Code Remote Containers: Azure Ansible

by Carlos Mendible on 05 Jul 2019 » Azure, DevOps

Last year I was working on a project for deploying Azure services using Ansible, and let me tell you something: Back then a feature like Visual Studio Remote Containers would have helped us so much!

Why? Because just installing Visual Studio Code, the Remote Development Extension Pack, and Docker you have a killer combo that makes it possible to create a Development environment in a snap and share it with your source code.

When I learned about this feature I tought I should create a Developer Container for those who need to work with Azure and Ansible so I went hands on and after collaborating with Chuck Lantz the container definition resulted in the following two files:

1. devcontainer.json


This file configures the remote container with the specified extensions

{
	"name": "Azure Ansible",
	"dockerFile": "Dockerfile",
	"runArgs": [
		// Uncomment the next line if you will use a ptrace-based debugger like C++, Go, and Rust.
		// "--cap-add=SYS_PTRACE", "--security-opt", "seccomp=unconfined",
		"-v", "/var/run/docker.sock:/var/run/docker.sock"
	],

	// Uncomment the next line if you want to publish any ports.
	// "appPort": [],

	// Uncomment the next line if you want to add in default container specific settings.json values
	// "settings":  { "workbench.colorTheme": "Quiet Light" },

	// Uncomment the next line to run commands after the container is created.
	// "postCreateCommand": "ansible --version",

	"extensions": [
		"vscoss.vscode-ansible",
		"redhat.vscode-yaml",
		"ms-vscode.azurecli"
	]
}

2. Dockerfile


This is the Dockerfile with all the tooling for the Development environment.
