What’s New

Execution dry run indication

The Executions Widget in the dashboard now displays a dry-run indicator in the attributes column for every dry-run execution. This allows quick differentiation between actual executions and dry-runs.

Dry-run indication:

Agents Widget

The Agents widget is a new dashboard tabular widget listing the Cloudify agents in the system.

The displayed attributes per each agent are: ID, IP, Deployment ID, Node ID, Hosting OS, Agent version, and installation mode.

The widget allows two operations: Installation of a new agent on selected deployments, and agent status validation.

Improved log filtering

Events and Logs widgets now allow sorting & filtering by operation, node, and node instances

Snapshots performance improvement

Snapshots are used for system backup, upgrades, and disaster recovery. Optimization of the snapshot restoration flow allows faster upgrade and recovery times.

Cloudify manager support for external database

The Cloudify manager can now be deployed with either embedded (same box) database or with existing customer maintained database.

Segregation of data store is a common compliance demand, hence some organizations are required to run the Cloudify manager database on their own self-maintained DB instance.

Blueprint support for namespaces

Introduction of namespaces into the Cloudify DSL allows easy import and embedding of external blueprints in your blueprint, with an explicit call to the relevant resources.

Learn more about the syntax & potential usage

Deployment capability declaration

When managing a large deployment, some scenarios require specific details about the deployment. The new <capabilities> declaration allows each deployment to expose certain properties which can later be retrieved in real-time via CLI or Rest API call to be used as part of a workflow or an interacting deployment.

Learn more about the syntax & potential usage

Resumable Workflows

Failed or canceled workflow executions can now be resumed. This is useful for cases in which an execution failed after some tasks were already executed and re-execution should skip these tasks.

Learn more about this

Scheduled Workflows

Workflow executions can now be scheduled to certain date and time.

Learn more about scheduling executions

Security – AES256 encryption

Secrets and passwords stored by Cloudify are now encrypted using AES256 (previous encryption was AES128)
During an upgrade, all encrypted data will be updated to the new AES256 encryption.

Agents OS support

Extended agent support for Ubuntu Bionic 18.04

Removed support for Ubuntu Precise 12.04

Composite and recursive intrinsic functions

Intrinsic functions allow usage of complex structures such as lists or YAML and allow the selection of a certain item in these objects. For example, get_input: [mylist,5] will get the fifth element in mylist.

One may also use this recursively and use an intrinsic function as a parameter in another intrinsic function.
