What's new in 2.2

This release of Juju 2.2 makes creating and managing cloud deployments faster and easier, thanks to several new and significant features:

  • Cloud updates: new support for Oracle's public cloud and big improvements to VMware's vSphere.
  • Performance: greatly enhanced memory and storage consumption, helping Juju run more efficiently for longer.

We're going to look at these new features in more detail below. If you're new to Juju, we recommend taking a look at our Getting started guide first.

Cloud updates

Oracle cloud

Oracle's public cloud, Oracle Compute, becomes our latest cloud addition.

Prior to deployment, you will need to associate Oracle's Ubuntu images within the dashboard of your Oracle Compute service because Juju uses these with its own deployments.

This can be done easily by signing in to Oracle's domain dashboard, creating a new Compute instance, selecting Marketplace and searching for 'ubuntu':

Ubuntu image search

Select the images you want, Ubuntu 16.04 and Ubuntu 14.04 are good choices, and head back to Juju.

You now need to simply add credentials and bootstrap.

Note: If you're using an Oracle cloud trial account, you will need to enter your endpoint details manually using juju add-cloud. See our Oracle documentation for help on the process.

Using Juju's interactive authentication, importing Oracle credentials into Juju is an easy process. You will just need the following information:

  • Username: usually the email address for your Oracle account.
  • Password: the password for this specific Compute domain.
  • Identity domain: the ID for the domain, e.g. a476989.

To add these details, type juju add-credential <credential-name> <cloud-name>:

juju add-credential oracle

You will be asked for each detail in turn.

Enter credential name: mynewcredential
Using auth-type "userpass".
Enter username: javier
Enter password: ********
Enter identity-domain: a476989
Credentials added for cloud oracle.

You have now added everything needed to bootstrap your new Oracle Compute cloud with Juju:

juju boostrap oracle

You can now start deploying Juju [charms and bundles][charms] to your Oracle cloud.

See our Using the Oracle public cloud documentation for further help.

VMware vSphere

Our vSphere support has been much improved. It now requires very little configuration prior to bootstrap and performs much better than with previous versions of Juju.

Additionally, to help with vSphere machine management, machines are now organised into folders on your cloud. See our vSphere documentation to get started.


Juju now handles transactions more efficiently and has better support for longer running controllers.

Logs are compressed when rotated, separated by model, and can be pruned to a specific age and size. These options are configured through the controller - see our Controller documentation for more details.

Next Steps
