Hi,  
I’m trying to automate opennebula DB backup. I was wondering if there is a way to load the credentials from some config file when using “onedb backup”. For the moment I know only the way of specifying the username/password on the command line and this is not very secure as password appears in process list and in the bash logs.

Thank you.

Hi,

The following patch to `onedb` enable using a shell variable named `ONE_DB_PASSWORD` for the database password:

             if !passwd
+ passwd = ENV['ONE_DB_PASSWORD']
+ end
+ if !passwd
                 passwd = get_password
             end

```

If this helps please open a [feature request issue](https://github.com/OpenNebula/one/issues) to move such patch upstream.
