How can I access Mysql database or my phabricator data ?

[2017-04-06 06:17:20] EXCEPTION: (AphrontConnectionQueryException) Attempt to connect to admin@database failed with error #2005: Unknown MySQL server host 'database' (0). at [/src/aphront/storage/connection/mysql/AphrontMySQLiDatabaseConnection.php:72]
arcanist(), phabricator(head=master, ref.master=8ff41264e495), phutil()

I am getting above exception while running ./bin/accountadmin in docker phabricator. As well my Mysql docker is not getting updated its database. How can I access the database and where the data is actually stored in these docker's ?
