OpenStack instance – setting a password

It is very important to set password for your instance. Why? Otherwise, if, e.g., something will go wrong with you network interface, you will not be able to access the instance via VNC console. Hence, you will not be able to access your instance at all, at least from the OpenStack’s web GUI.

Although it is of course possible to set up the password after the first logging in to your machine with SSH, I recommend setting it up during configuring the machine. In order to do so, you have to

In the Script section (this sets password fot the user):

password: mypassword
chpasswd: { expire: False }
ssh_pwauth: True

Where: mypassword is password for your user, e.g.:

password: ^NwE67!UV-xZ!yj"
chpasswd: { expire: False }
ssh_pwauth: True

It should look similar to that:
