○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-alpine3.8
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-connector-c \
&& 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用のMariaDBイメージの作成(Dockerfile-mariadbとsetupdb.shのあるディレクトリで実行)
docker build -f Dockerfile-mariadb -t mariadb-mezzanine .Dockerfile-mariadb
FROM alpine:3.8
COPY ./setupdb.sh /
RUN apk --no-cache add mariadb mariadb-client \
&& addgroup mysql mysql \
&& chmod +x /setupdb.sh
VOLUME /var/lib/mysql
EXPOSE 3306
ENTRYPOINT ["/setupdb.sh"]
setupdb.sh
#!/bin/sh
if [ ! -d "/run/mysqld" ]; then
mkdir -p /run/mysqld
chown -R mysql:mysql /run/mysqld
fi
if [ ! -e /usr/my.cnf ]; then
cat << EOF > /usr/my.cnf
[mysqld]
datadir=/var/lib/mysql
log-bin = /var/lib/mysql/mysql-bin
port = 3306
user = mysql
symbolic-links=0
character-set-server = utf8
pid-file=/run/mysqld/mysqld.pid
EOF
chown -R mysql:mysql /var/lib/mysql
mysql_install_db --user=mysql
nohup /bin/sh /usr/bin/mysqld_safe \
--datadir=/var/lib/mysql \
--socket=/run/mysqld/mysqld.sock \
--pid-file=/run/mysqld/mysqld.pid \
--basedir=/usr \
--user=mysql \
--skip-grant-tables \
--skip-networking &
while :
do
[ -r /run/mysqld/mysqld.pid ] || continue
if ps -ef | grep -q $(cat /run/mysqld/mysqld.pid) ; then
break
fi
sleep 10
done
cat << EOF > /tmp/setupdb.sql
USE mysql;
UPDATE mysql.user SET Password=PASSWORD('mezzanine') WHERE User='root';
FLUSH PRIVILEGES;
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'mezzanine';
FLUSH PRIVILEGES;
EOF
/usr/bin/mysql < /tmp/setupdb.sql
cat << EOF > /tmp/createdb.sql
CREATE DATABASE mezzanine DEFAULT CHARACTER SET utf8mb4;
EOF
/usr/bin/mysql -uroot -pmezzanine < /tmp/createdb.sql
kill `cat /run/mysqld/mysqld.pid`
sleep 10
fi
exec /usr/bin/mysqld --defaults-file=/usr/my.cnf --console --user=mysql --character-set-server=utf8mb4 --collation-server=utf8mb4_unicode_ci
3. MezzanineとMariaDB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 -ddocker-compose.yml
version: "2"
services:
db:
image: mariadb-mezzanine
container_name: "mezzanine-db"
volumes:
- "db-data:/var/lib/mysql"
ports:
- "3306:3306"
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
