php-fpm Dockerfile

以下の内容ならばdocker-compose.ymlのimageプロパティに直接指定すればよいが、buildプロパティの例としてDockerfileに記載する。

FROM php:7.4-fpm

実行手順

1. docker-compose build
2. docker-compose up -d

$ docker-compose build

$ docker image ls
docker image ls
REPOSITORY              TAG       IMAGE ID       CREATED       SIZE
nginx-php-fpm_php-fpm   latest    eb029ced96bd   12 days ago   443MB
php                     7.4-fpm   eb029ced96bd   12 days ago   443MB
nginx                   latest    fa5269854a5e   12 days ago   142MB

phpサービスのイメージ名は以下の命名規則に従う。

• image名：ディレクトリ名_サービス名

$ docker-compose up -d
Creating network "nginx-php-fpm_default" with the default driver
Creating nginx-php-fpm_php-fpm_1 ... done
Creating nginx-php-fpm_nginx_1   ... done
