Question

我正在尝试使用docker-compose从docker hub的vanilla mariadb图像启动一个docker容器。虽然以前一切正常，但我现在收到错误消息Can't create/write to file '/tmp/ibLTxiq7' (Errcode: 13 "Permission denied")。这是完整的日志：

我不明白，日志中的/tmp文件夹是指主机还是容器？我该如何解决这个问题？

我尝试运行的命令（以root用户身份）是docker-compose up db。我已经检查过磁盘上确实有空间。我的操作系统Ubuntu 16.04。

更新：我的docker-compose.yml-file

https-portal:
  image: steveltn/https-portal
  ports:
    - '80:80'
    - '443:443'
  links:
    - wordpress
  restart: always
  environment:
    DOMAINS: 'domain.com -> http://wordpress'
    STAGE: 'production'
wordpress:
  image: wordpress
  links:
    - db:mysql
  volumes:
    - ~/wordpress/wp_html:/var/www/html
db:
  image: mariadb
  environment:
    MYSQL_ROOT_PASSWORD: [---]

更新2：

我似乎已经（至少暂时）通过为db容器添加卷装入路径来解决问题，而且令人惊讶：

db:
  image: mariadb
  volumes:
    - /data/maridb:/var/lib/mysql

然而这实际上并没有影响任何事情，它只是打印一个警告，表示卷装载未被使用（事实上它不是）因为容器以前有过使用不同的卷创建并使用旧的卷。仍然，原始问题消失了。有关导致这种行为的原因的任何想法？

Docker-compose无法启动mysql，权限被拒绝/ tmp
