DockerでMezzanine、Percona Serverがインストールされたコンテナ(Alpine3.7)を構築する

MezzanineはPython製のCMSです。

○Mezzanineの画面

○構築方法
以下の手順で、Mezzanineのコンテナを構築・実行します。

1. Mezzanineイメージの作成(Dockerfileがあるフォルダで実行)

docker build -t mezzanine .

Dockerfile

FROM python:3.6-alpine3.7

RUN mkdir -p /opt/mezzanine
WORKDIR /opt/mezzanine
RUN apk update \
  && apk add --no-cache --virtual=build-deps jpeg jpeg-dev zlib-dev musl-dev gcc mariadb-dev build-base \
  && pip install mezzanine \
  && pip install mysqlclient \
  && apk del mariadb-dev build-base build-deps gcc \
  && apk add mariadb-client mariadb-client-libs \
  && rm -rf /var/cache/apk/* \
  && mezzanine-project mysite \
  && echo $'#!/bin/sh \n\
until mysql -h db -u root -pmezzanine mezzanine\n\
do \n\
  echo -n "." \n\
  sleep 1 \n\
done \n\
cd /opt/mezzanine/mysite \n\
sed -i -e \'s/"ENGINE": "django.db.backends.sqlite3",/"ENGINE": "django.db.backends.mysql",/\' /opt/mezzanine/mysite/mysite/local_settings.py \n\
sed -i -e \'s/"NAME": "dev.db",/"NAME": "mezzanine",/\' /opt/mezzanine/mysite/mysite/local_settings.py \n\
sed -i -e \'s/"USER": "",/"USER": "root",/\' /opt/mezzanine/mysite/mysite/local_settings.py \n\
sed -i -e \'s/"PASSWORD": "",/"PASSWORD": "mezzanine",/\' /opt/mezzanine/mysite/mysite/local_settings.py \n\
sed -i -e \'s/"HOST": "",/"HOST": "db",/\' /opt/mezzanine/mysite/mysite/local_settings.py \n\
sed -i -e \'s/"PORT": "",/"PORT": "3306",/\' /opt/mezzanine/mysite/mysite/local_settings.py \n\
sed -i -e \'s/# ALLOWED_HOSTS = \[""\]/ALLOWED_HOSTS  = ["*"]/\' /opt/mezzanine/mysite/mysite/local_settings.py \n\
python manage.py createdb --noinput \n\
python manage.py migrate --noinput \n\
python manage.py runserver 0.0.0.0:80' > /opt/mezzanine/mysite/start.sh \
  && chmod +x /opt/mezzanine/mysite/start.sh
EXPOSE 80
VOLUME /opt/mezzanine/mysite
CMD ["/opt/mezzanine/mysite/start.sh"]

2. MezzanineとPercona Serverコンテナの構築・実行(docker-compose.ymlがあるフォルダで実行)

docker-compose up -d

docker-compose.yml

version: "2"
services:
  db:
    image: percona:5.7
    command: mysqld --character-set-server=utf8mb4 --collation-server=utf8mb4_unicode_ci
    container_name: "mezzanine-db"
    volumes:
      - "db-data:/var/lib/mysql"
    ports:
      - "3306:3306"
    environment:
        MYSQL_DATABASE: mezzanine
        MYSQL_ROOT_PASSWORD: mezzanine
  mezzanine:
    image: mezzanine
    container_name: "mezzanine"
    volumes:
      - "mezzanine-data:/opt/mezzanine/mysite"
    ports:
      - "80:80"
    depends_on:
      - db
volumes:
  db-data:
    driver: local
  mezzanine-data:
    driver: local
