我有以下docker-compose.yml文件:
version: "3"
services:
dbs-poa-loc001d:
image: percona
volumes:
- ./mysql_backup:/var/lib/mysql
- ./create_databases:/docker-entrypoint-initdb.d
hostname: "dbs-poa-loc001d"
container_name: dbs-poa-loc001d
environment:
MYSQL_ALLOW_EMPTY_PASSWORD: "yes"
ports:
- "3306:3306"
networks:
- azion-network
...
当我尝试创建dbs-poa-loc001d服务(项目的数据库)时,出现以下错误:
Starting dbs-poa-loc001d ... done

在我的工作中,我的MacOS计算机上不会发生此错误,但在我的家用计算机(运行Ubuntu 16.04)中会发生此错误。我确实注意到创建的用于保存卷数据的主机上的mysql_backup
文件夹设置为组AND用户root。谁能告诉我怎么回事,如何解决?已经尝试不成功:
我当前的设置和安装版本是:
sudo pip install docker-compose
答案 0 :(得分:1)
您可以尝试将mysql_backup
的权限设置为1001:0吗?
类似sudo chown -R 1001:0 ./mysql_backup
或作为替代,但仅在文件夹为空 sudo chmod 777 ./mysql_backup
关于percona Dockerfile mysql用户ID为1001 https://github.com/percona/percona-docker/blob/master/percona-server.80/Dockerfile
