dev-init

Dev Init is a simple CLI tool that allows you to easily install and manage docker based dev environments for several project types. Dev init will install a docker-local folder into your project that contains the full docker environment required to start developing. Dev-init also provides you with convenience commands to allow you to do common tasks from witin the containers.

Dependencies

• Dev-init requires that go is installed on your machine. Installation details can be found here.

Definitions

• Context - this refers to the directory from where the dev command is being run from. dev will alter the commands available depending on which framework or project type it detects within the current directory.

• Module - A module refers to the driver code that allows dev init to be context aware (see the Modules section for more details).

Instalation

git clone [email protected]:AdamHutchison/dev-init.git
cd dev-init
make

Once you have run the Makefile check that the dev command is globally installed by running dev.

After you've confirmed dev is working, cd into a php project and run dev install. This will create a docker-local folder containing all the config you need for your dev environment.

Commands

Base Commands

These commands are available regardless of where you run the dev command from.

down Kill all running containsers

rm Remove all containers

Common Commands

These commands are available from within any context:

build Build the dev-local containers

down Kill all running containsers

exec Exec a command with the php container

help Help about any command

install Installs the base docker configuration into your application

up Brings the docker files for the project up

logs Shows the docker-compose logs for the project

ssh SSH into a given docker compose container. Either provide the command with a --service (name of a service from docker-local/docker-compose.yml) flag or it'll default to the main docker compose service.

Context Awareness

Dev-init is context aware. this means that the available dev commands will alter depending on which project type you are in. Currently the supported frameworks are:

• Laravel (PHP)
• Wordpress (PHP)
• Laminas (PHP)
• Buffalo (Golang)

To see the specific commands available for each framework checkout the modules/context_modules directory.

Modules

Overview

Dev-init achieves context awareness using modules. Modules can be thought of as drivers for different frameworks / project types. Dev Init can be extended to provide useful project / framework specific commands. A module, at it's core, consists of several cobra commands as well as a module specific instance of the module.Module struct.

The module defines all the specific information needed to register the module and for the module to run the base commands:

• Name - this is used to locate the docker-local folder when installing them into a project. The module specific docker-local folder must be placed in the resources/{NAME} directory. i.e. For the laravel module, the resources are located in the resources/laravel/docker-local folder.

• Identifier - this is a framework specific file or directory that dev-init will look for in order to determine what the project type is.

• Docker image - this defines the core docker image to be used in the docker file. A version must also be passed in on install. For laravel the docker image is php so running dev install --version=8.0-fpm would result in the php:8.0-fpm being used.

• Dockerfile path - dev-init needs to know the path of the main dockerfile in order to insert the correct base image to extend from at the top of it.

• A list of context specific commands. These will only be available in the projects where the Identifier exists.

package laravel

import (
	"github.com/AdamHutchison/dev-init/modules"
	"github.com/AdamHutchison/dev-init/modules/general/php"
	"github.com/spf13/cobra"
)

var Module = modules.Module {
	Name: "laravel",
	Identifier: "artisan",
	DockerImage: "php",
	DockerFilePath: "docker-local/conf/php/Dockerfile",
	Commands: []*cobra.Command {
		ArtCmd,
		RouteListCmd,
		php.TestCmd,
	},
}

The Base Module (Digging Deeper)

The base module defines commands that are always available.

The Common Module

The common module defines commands that are availavble from within any context (but only if thwre is a context!).

Module Registration

Once you have created a module it must be registerd within the GetContextModules() function of the github.com/AdamHutchison/dev-init/modules/register package.
