mkcertを使ってローカル環境でもDockerでも楽々SSL

Last updated at Posted at 2018-08-18

概要

mkcertをTwitterで見てローカル環境でもDockerでも楽々にSSLができるとのことで試して見た。

環境

Docker for Mac

ディレクトリ構成

ssl-test/
├── ssl-conf/
│  ├── httpd/
│  │   └── ssl.conf
│  └── secret-keys/
│    ├── localhost+1.pem
│     └── localhost+1-key.pem
├── index.php
├── Dockerfile
└── docker-compose.yml

docker-compose.ymlの記述

docker-compose.yml
version: '3'
services: 
  ssl:
    build: ./
    ports:
      - 80:80
      - 443:443
    privileged: true
    volumes: 
      - ./:/var/www/html
    container_name: 'ssl'

Dockerfileの記述

FROM centos:7.5.1804

RUN yum -y update

# 外部リポジトリ(EPEL, Remi)を追加
RUN yum -y install epel-release
RUN yum -y install http://rpms.remirepo.net/enterprise/remi-release-7.rpm

# apache その他 phpパッケージを導入
RUN yum -y install httpd
RUN yum -y install --enablerepo=remi,remi-php72 php php-cli php-common php-devel php-fpm php-gd php-mbstring php-mysqlnd php-pdo php-pear php-pecl-apcu php-soap php-xml php-xmlrpc 

RUN yum -y install mod_ssl openssl

CMD ["/usr/sbin/httpd","-D","FOREGROUND"]

WORKDIR /var/www/html

index.phpの記述

<?php phpinfo(); ?>
// 記述は何でも良い

Dockerfileのbuildおよびdocker-composeの立ち上げ

docker-compose build
docker-compose up -d

ssl.confの作成

docker-compose exec ssl bash
cat /etc/httpd/conf.d/ssl.conf > /var/www/html/ssl.conf

作成したssl.confssl-conf/httpdディレクトリに配置する。

mkcertのインストール

コンテナの外に出て(exit外に出る)


brew install mkcert
mkcert -install
mkcert localhost 127.0.0.1

を実行する。

作成されたlocalhost+1.pem localhost+1-key.pem を ssl-conf/secret-keysに配置する。

ssl.confの編集

ssl.conf
- SSLCertificateFile /etc/pki/tls/certs/localhost.crt
+ SSLCertificateFile /var/www/html/ssl-conf/secret-keys/localhost+1.pem

- SSLCertificateKeyFile /etc/pki/tls/private/localhost.key
+ SSLCertificateKeyFile /var/www/html/ssl-conf/secret-keys/localhost+1-key.pem

dokcer-compse.ymlの編集

docker-comopse.yml
version: '3'
services: 
  ssl:
    build: ./
    ports:
      - 80:80
      - 443:443
    privileged: true
    volumes: 
      - ./:/var/www/html
      - ./ssl-conf/httpd/ssl.conf:/etc/httpd/conf.d/ssl.conf
    container_name: 'ssl'

再度docker-compose up -dでコンテナを立ち上げlocahlostに接続する。
