簡介

Docker可以想像將環境容器化
先前有提到，Laravel有提供Sail，但筆者不太喜歡用
原因是:

1. Sail還是必須安裝PHP、Composer等
2. Windows不方便使用

所以今天不用Sail，單純用Docker建立起本地環境

安裝

使用Docker前必須安裝Docker，筆者用Windows使用了Docker Desktop
安裝還需要用WSL、Hyper等，請自行安裝

開始

開啟Docker Desktop

使用Laravel搭配Docker

nginx\conf.d\app.conf

server {
    listen 80;
    index index.php index.html;
    error_log  /var/log/nginx/error.log;
    access_log /var/log/nginx/access.log;
    root /var/www/public;
    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass app:9000;
        fastcgi_index index.php;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_param PATH_INFO $fastcgi_path_info;
    }
    location / {
        try_files $uri $uri/ /index.php?$query_string;
        gzip_static on;
    }
}

mysql\my.cnf

[mysqld]
general_log = 1
general_log_file = /var/lib/mysql/general.log

Dockerfile(專案根目錄下)

FROM php:8.2-fpm

# Copy composer.lock and composer.json
COPY composer.lock composer.json /var/www/

# Set working directory
WORKDIR /var/www

# Install dependencies
RUN apt-get update && apt-get install -y \
    build-essential \

# Install extensions
RUN docker-php-ext-install pdo_mysql

# Clear cache
RUN apt-get clean && rm -rf /var/lib/apt/lists/*

# Install composer
RUN curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer

# Add user for laravel application
RUN groupadd -g 1000 www
RUN useradd -u 1000 -ms /bin/bash -g www www

# Copy existing application directory contents
COPY . /var/www

# Copy existing application directory permissions
COPY --chown=www:www . /var/www

# Change current user to www
USER www

# Expose port 9000 and start php-fpm server
EXPOSE 9000
CMD ["php-fpm"]

RUN

docker-compose up -d

啟動後，可以進入http://localhost/

如果要跑php artisan指令

docker-compose exec app php artisan ...

其他一些常用的docker指令
查詢containner

    docker ps -a
    docker logs <app_container_id_or_name>

進入containner

    docker exec -it <container_name_or_id> /bin/bash

删除所有容器（Containers）

    docker rm -f $(docker ps -aq)

删除所有鏡像（Images）

    docker rmi -f $(docker images -aq)

總結

本篇讓讀者能快速起步使用docker架起laravel
當然還有許多地方可以延伸，mysql、redis，當然還有上次Horizon的ext可以嘗試裝好，架起來運作
太多細部的部分，這邊就不多做教學，讀者朝著自己所需去做搭配即可
