启动之后无法配置成功，数据库过不去，怎么初始化？不是知道创建的吗？

docker run --name tigase-server -p 8080:8080 -p 5222:5222 tigase/tigase-xmpp-server:8.1.0

始终不能初始化通过
要怎么设置数据库连接？

http://localhost:8080/setup 设置的内容为：

admins = [ 'admin@e1498daba259' ]
'config-type' = 'default'
debug = [ 'server' ]
'default-virtual-host' = 'e1498daba259'
dataSource () {
    default () {
        uri = 'jdbc:mysql://localhost:3306/tigasedb?user=root&password=123456&useSSL=false&useLegacyDatetimeCode=false&allowPublicKeyRetrieval=true'
    }
}
http () {
    setup () {
        'admin-password' = '1000'
        'admin-user' = '1000'
    }
}
pubsub () {
    trusted = [ 'http@{clusterNode}' ]
}

不要使用localhost*(或：127.0.0.1)

@HeroBarry please use English so more people can participate :-)

For people stumbling against this issue: the OP set up tigase-server in docker with database connection configured with localhost, which obviously is not provided within docker image.

Solution: use dedicated database instance (for example MySQL) and during setup provide it's hostname.
