NYU DevOps Starter Lab 2 | 3 | [![License](https://img.shields.io/badge/License-Apache_2.0-blue.svg)](https://opensource.org/licenses/Apache-2.0) 4 | 5 | This first lab is to ensure that your development environment is working correctly. You should only need to install this software once to be ready for all of the labs in this course. 6 | 7 | You can read more about creating these environments in my article: [Creating Reproducable Development Environments](https://johnrofrano.medium.com/creating-reproducible-development-environments-fac8d6471f35) 8 | 9 | ## Prerequisite Software Installation 10 | 11 | This lab uses Docker and Visual Studio Code with the Remote Containers extension to provide a consistent repeatable disposable development environment for all of the labs in this course. 12 | 13 | You will need the following software installed: 14 | 15 | - [Git](https://git-scm.com/downloads) 16 | - [Docker Desktop](https://www.docker.com/products/docker-desktop) 17 | - [Visual Studio Code](https://code.visualstudio.com) 18 | - [Remote Containers](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-containers) extension from the Visual Studio Marketplace 19 | 20 | All of these can be installed manually by clicking on the links above or you can use a package manager like **Homebrew** on Mac of **Chocolatey** on Windows. 21 | 22 | ### Install on macOS using Homebrew 23 | 24 | If you are using a Mac it is strongly suggested that you use `homebrew` to manage all of your development tools. If you don't have homebrew you can install it from [brew.sh](http://brew.sh) or just open a `terminal` and use this command: 25 | 26 | ```bash 27 | /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)" 28 | ``` 29 | 30 | Once installed you can install all of the prerequisite software for the labs using these commands: 31 | 32 | ```bash 33 | xcode-select --install 34 | ``` 35 | 36 | This will install prerequisites for `git`. Then install the tools with: 37 | 38 | ```bash 39 | brew install git 40 | brew install --cask docker 41 | brew install --cask visual-studio-code 42 | ``` 43 | 44 | You must setup Visual Studio Code as a Mac to launch from the command line using these [instructions](https://code.visualstudio.com/docs/setup/mac#_launching-from-the-command-line). Then you can run the `code` command to install the remote containers extension. 45 | 46 | ```bash 47 | code --install-extension ms-vscode-remote.remote-containers 48 | ``` 49 | 50 | That's it! You can now [bring up the development environment](#bring-up-the-development-environment). 51 | 52 | ### Install on Windows using Chocolatey 53 | 54 | If you are using a Windows it is strongly suggested that you use `choco` to manage all of your development tools. If you don't have Chocolatey you can find instructions to install it from [chocolatey.org](https://docs.chocolatey.org/en-us/choco/setup) 55 | 56 | Open a **Command Prompt** (`cmd`) and then: 57 | 58 | ```cmd 59 | @"%SystemRoot%\System32\WindowsPowerShell\v1.0\powershell.exe" -NoProfile -InputFormat None -ExecutionPolicy Bypass -Command "[System.Net.ServicePointManager]::SecurityProtocol = 3072; iex ((New-Object System.Net.WebClient).DownloadString('https://community.chocolatey.org/install.ps1'))" && SET "PATH=%PATH%;%ALLUSERSPROFILE%\chocolatey\bin" 60 | ``` 61 | 62 | Once installed you can install all of the prerequisite software for the labs using these commands: 63 | 64 | ```bash 65 | choco install git 66 | choco install docker-desktop 67 | choco install vscode 68 | code --install-extension ms-vscode-remote.remote-containers 69 | ``` 70 | 71 | That's it! You can now [bring up the development environment](#bring-up-the-development-environment). 72 | 73 | ## Bring up the development environment 74 | 75 | To bring up the development environment you should clone this repo, change into the repo directory, and then open Visual Studio Code using the `code .` command. VS Code will prompt you to reopen in a container and you should say **yes**. This will take a while as it builds the Docker image and creates a container from it to develop in. 76 | 77 | ```bash 78 | git clone https://github.com/nyu-devops/lab-starter.git 79 | cd lab-starter 80 | code . 81 | ``` 82 | 83 | Note that there is a period `.` after the `code` command. This tells Visual Studio Code to open the editor and load the current folder of files. 84 | 85 | Once the environment is loaded you should be placed at a `bash` prompt in the `/app` folder inside of the development container. This folder is mounted to the current working directory of your repository on your computer. This means that any file you edit while inside of the `/app` folder in the container is actually being edited on your computer. You can then commit your changes to `git` from either inside or outside of the container. 86 | 87 | ## Bring down the development environment 88 | 89 | There is no need to manually bring the development environment down. When you close Visual Studio Code it will wait a while to see if you load it back up and if you don't it will stop the Docker containers. When you come back again, it will start them up and resume where you left off. 90 | 91 | If you want to manually close the containers you can use the command pallet and select **Close Remote Connection**. If you want to permanently delete the container you can use Docker commands to: 92 | 93 | ```bash 94 | docker ps -a 95 | docker stop 96 | docker rm 97 | ``` 98 | 99 | Where `` is the id of the container returned from the `docker ps -a` command. 100 | 101 | For Example: 102 | 103 | ```bash 104 | $ docker ps -a 105 | (master) 106 | CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 107 | d9c94acd264b vsc-lab-starter-2013d33dfd4af07fa71a13e87cbc6b63 "/bin/sh -c 'echo Co…" 56 minutes ago Up 56 minutes 5000/tcp affectionate_elgamal 108 | 109 | $ docker stop d9c94acd264b 110 | $ docker rm d9c94acd264b 111 | ``` 112 | 113 | ## License 114 | 115 | Copyright (c) 2020-2024 John Rofrano.
