docker-compose删除共享卷
我有这个LEMP堆栈：
cadvisor: image: google/cadvisor:latest container_name: lemp_cadvisor ports: - "8080:8080" volumes: - "/:/rootfs:ro" - "/var/run:/var/run:rw" - "/sys:/sys:ro" - "/var/lib/docker/:/var/lib/docker:ro" base: build: ./base container_name: lemp_base volumes: - /home/core/server-lemp/www:/var/www:rw phpmyadmin: build: ./phpmyadmin container_name: lemp_phpmyadmin volumes_from: - base volumes: - /var/www/phpmyadmin - ./phpmyadmin/var/www/phpmyadmin/config.inc.php:/var/www/phpmyadmin/config.inc.php:rw ffmpeg: build: ./ffmpeg container_name: lemp_ffmpeg volumes_from: - phpmyadmin volumes: - /usr/ffmpeg mariadb: build: ./mariadb container_name: lemp_mariadb environment: - MYSQL_ROOT_PASSWORD=your-pwd volumes_from: - ffmpeg volumes: - /var/run/mysqld - /home/core/server-lemp/mariadb:/var/lib/mysql:rw - ./mariadb/etc/mysql/my.cnf:/etc/mysql/my.cnf:ro php: build: ./php container_name: lemp_php volumes_from: - mariadb volumes: - /var/run/php-fpm - ./php/usr/local/php7/etc/php-fpm.conf:/usr/local/php7/etc/php-fpm.conf:ro - ./php/usr/local/php7/etc/php.ini:/usr/local/php7/etc/php.ini:ro - ./php/usr/local/php7/etc/php-fpm.d/www.conf:/usr/local/php7/etc/php-fpm.d/www.conf:ro - ./php/etc/supervisor/conf.d/supervisord.conf:/etc/supervisor/conf.d/supervisord.conf:ro - ./php/etc/cron.d:/etc/cron.d:ro nginx: build: ./nginx container_name: lemp_nginx net: "host" ports: - "80:80" - "443:443" volumes_from: - php volumes: - /var/cache/nginx - ./nginx/etc/nginx/nginx.conf:/etc/nginx/nginx.conf:ro 当我启动这个堆栈时，每个文件都将在我的主机上的/home/core/server-lemp/www上被删除，共享给/var/www 。
在过去这并没有发生，新的命令是唯一的net: "host" Nginx下的net: "host" 。
这是我的docker-compose日志的样子：

更新2：
似乎你不能雏菊链你的容器来创build一个构build顺序，因为在mariadb发生的事情是导致所有的静态networking服务器文件的删除。
这是我现在的docker-compose文件，我回到了我的旧的解决scheme，我曾经把所有的东西都链接到底层，而不是把它们分享到php中，而不是把它们链接起来：
cadvisor: image: google/cadvisor:latest container_name: lemp_cadvisor ports: - "8080:8080" volumes: - "/:/rootfs:ro" - "/var/run:/var/run:rw" - "/sys:/sys:ro" - "/var/lib/docker/:/var/lib/docker:ro" base: build: ./base container_name: lemp_base volumes: - /root/lemp_base_volume www: image: lemp_base container_name: lemp_www volumes_from: - base volumes: - /home/core/server-lemp/www:/var/www:rw phpmyadmin: build: ./phpmyadmin container_name: lemp_phpmyadmin volumes_from: - base volumes: - /var/www/phpmyadmin - ./phpmyadmin/var/www/phpmyadmin/config.inc.php:/var/www/phpmyadmin/config.inc.php:rw ffmpeg: build: ./ffmpeg container_name: lemp_ffmpeg volumes_from: - base volumes: - /usr/ffmpeg mariadb: build: ./mariadb container_name: lemp_mariadb environment: - MYSQL_ROOT_PASSWORD=your-db-pwd volumes_from: - base volumes: - /var/run/mysqld - /home/core/server-lemp/mariadb:/var/lib/mysql:rw - ./mariadb/etc/mysql/my.cnf:/etc/mysql/my.cnf:ro php: build: ./php container_name: lemp_php volumes_from: - www - phpmyadmin - ffmpeg - mariadb volumes: - /var/run/php-fpm - ./php/usr/local/php7/etc/php-fpm.conf:/usr/local/php7/etc/php-fpm.conf:ro - ./php/usr/local/php7/etc/php.ini:/usr/local/php7/etc/php.ini:ro - ./php/usr/local/php7/etc/php-fpm.d/www.conf:/usr/local/php7/etc/php-fpm.d/www.conf:ro - ./php/etc/cron.d:/etc/cron.d:ro nginx: build: ./nginx container_name: lemp_nginx ports: - "80:80" - "443:443" volumes_from: - php volumes: - /var/cache/nginx - ./nginx/etc/nginx/nginx.conf:/etc/nginx/nginx.conf:ro
我创build了一个名为www的新容器，它是从主机共享的静态Web服务器文件的基础映像。 现在base只需要，因为每个其他的图像将从这个图像构build。
就像在我以前的解决scheme中，我使用link创buildnetworking一样，每个共享卷都将在php和php的共享内容中与nginx共享，这是最重要的。
所以：
links: - base
变成了：
volumes_from: - base
维护构build顺序并确保首先构buildbase 。
我用docker-compose --x-networking --x-network-driver=bridge up为这个堆栈创build了一个桥接networking。
但看起来像cron作业不工作，再次。
UPDATE3：
这是我用rsyslog得到的：
root@0687540163a3:/var/log# cat syslog Jan 22 14:45:04 0687540163a3 rsyslogd: [origin software="rsyslogd" swVersion="8.4.2" x-pid="13" x-info="http://www.rsyslog.com"] start Jan 22 14:45:04 0687540163a3 rsyslogd: imklog: cannot open kernel log(/proc/kmsg): Operation not permitted.

这是我的wpcron文件的样子：
*/1 * * * * www-data php /var/www/domain.com/wp-cron.php >> /var/log/wp-cron.log 2>&1
在第一个5分钟之后，/ /var/log/wp-cron.log仍然没有创build。
我遇到了与你同样的问题。我认为， lemp_mariadb容器有一些问题。
解决这个问题。 您应该尝试以下步骤：获取lemp_mariadb容器ID：
docker ps -a
如果您看到lemp_mariadb状态为Dead 。 你应该去/var/lib/docker/containers 。 您可以find与lemp_mariadb容器标识名称相同的目录并将其删除
rm -rf /var/lib/docker/containers/lemp_mariadb_container_id
