These features have changed and been improved in the Playground compared to the Cloud Servers.
Credentials - Username and Password
The Playground servers now have a default username of 'cloud_user' matching the one typically used in Learning Activities and Challenges. The default password is now also randomly generated. You can view the credentials by looking at the details for the server in the Playground. Clicking on the clipboard next to the credential item will copy it to your clipboard so you can paste it in.
The previous user account 'user' and password '123456' will still work for the time being, but may be removed in a future update.
In Cloud Servers, you could set a tag on a server, but you could only select from a predefined list. The new Playground allows you to enter a custom tag when creating the server.
The tag will then display in the Playground server list, easily allowing you to see which of your servers is which.
In the Cloud Servers, some distributions have VNC installed on the server, but do not have it running by default. You could start the service manually and then connect using any VNC program.
In the new Playground, this has changed slightly. Now, VNC is available on several distribution choices and will automatically startup with the server. You can access this by clicking the 'Graphical Shell' button in the actions menu for the server. You cannot, however, connect with your own VNC client.
Note: In the Playground servers, Remote VNC access is blocked. You can only access the Graphical Shell (VNC) by using the Graphical Shell button from the Server Actions menu!
The Server Actions menu is available by clicking the three vertical dots to the left of the Cloud Server Name, Status, and Delete buttons. There is also a button for it in the Server Details as well.
The available actions for that distribution will be listed after you click the button. Click the Graphical Shell button to open a new tab that will automatically connect and login to the graphical shell via VNC. It uses the cloud_user account and the randomly generated password that is shown in the server details for connections. If you change the VNC password for the cloud_user account, this will stop working. You can fix this by changing it back to the default password.
