What’s New?

Cloudify Manager

  • You can now explicitly specify whether plugins are to be installed from source during deployment creation.
  • You can use the teardown command in the command line interface to remove Cloudify Manager and all its resources from a VM.
  • Cloudify Manager no longer requires a root user for its operation.
  • You can specify resources as private to increase isolation within tenants.
  • To enhance multi tenancy isolation and boundaries, agents belonging to one tenant cannot trigger operations on another tenant. Achieved through RabbitMQ isolation between tenants.

Web User Interface

  • You can now create your own custom widgets to assist you in displaying your data in a custom manner, or can integrate the Cloudify UI with other components in your architecture.

Widgets can be written using two different methods.

    • Using the React Utility is the recommended method, and requires a build operation to be executed. You can build the widget.js file yourself, or use the Cloudify build system.
    • Pure Vanilla JavaScript which enables attachment of an HTML template file. The callbacks for this method are described later in this topic.
  • A custom widget environment is now available on which you can develop and test your widgets.

Cloudify Composer

  • Cloudify Composer is now integrated into Cloudify Manager, eliminating the need for separate installation and making the process of uploading composed blueprints to the Manager easy and intuitive.

Upgrading to Cloudify 4.1

To upgrade from Cloudify 4.0.x to Cloudify 4.1, you must create a snapshot of your 4.0.x machine, and upload it to a tenant on Cloudify 4.1.0. Before you start, it is important that you review the upgrade options. Note also that snapshots can only be restored to clusters that have only a single node.

Note

:
Before beginning the upgrade process, please review the Known Issues section at the end of these release notes.

  • Restoration using the CLI is described here.
  • Restoration from the UI is described here.

Migration Procedure

If you are migrating from Cloudify 3.4.x to Cloudify 4.1, follow this procedure to perform the migration.

PREREQUISITE

Before taking the snapshot, verify that there are not any instances of node ID or deployment ID that include an underscore. For example, change node_ID to node-ID.

  1. Take a snapshot of Cloudify 3.4.x according to the installation instructions in the Cloudify 3.4.x documentation.
  2. Install Cloudify 4.1.0 according to the installation instructions in the Cloudify 4.1.0 documentation.
  3. On the newly installed manager, upload and restore the 3.4.x snapshot.
    You can restore a snapshot to a Manager that does not have any data on it (clean), or to one with existing content.

    Note:

    The snapshot is uploaded to the tenant on which you performed the upload operation.

Restore the uploaded snapshot into a specific tenant by specifying a new (unique) tenant name. The tenant is created as part of the restore process, and is populated with the snapshot content.

    • Restoration using the CLI is described here.
    • Restoration from the UI is described here.

Known Issues

The following issues are known to exist in this release:

Upgrading Cloudify Manager

  • SSH key files on tenants other than the default tenant are not included in the snapshot creation and restoration process. It is recommended that you use secrets to store this data, ensuring a proper upgrade.

    Workaround

    : When you are creating your snapshot of Cloudify Manager 4.x, you can pass the –exclude-credentials flag. This prevents the store/retrieve process from being touched. You can then recreate the keys from the original Cloudify Manager in the same locations on the new Cloudify Manager.

  • An agent upgrade is not automatically performed on tenants, other than the default tenant.

    Workaround

    : To upgrade the agent on a tenant other than the default, run
    cfy agents install -t TENANT_NAME

  • Before taking a snapshot of a Cloudify Manager version 4.0.x, it is important that you run the process described in the documentation including tearing down existing Manager. During the process, essential patches are applied.

Cloudify Web Interface

  • STAGE-397 – A user without admin permissions cannot see a tenant’s secrets in the user interface. To use secrets, a user without admin permissions must use the CLI.

High Availability

  • CFY-7039 – If, when you start a cluster user the floating IP of a Manager(default), the required ports are not open, an error message is not displayed. It will appear that the cluster has started correctly.

    Workaround

    : After you have started a cluster, view the Nodes list and verify that the node is online and does not have a FAILED DB status.

  • CFY-7030 – If you start a cluster with a single Manager instance, and that Manager becomes unavailable, when you attempt to connect a new (second) Manager to the cluster, an error message is returned that there is no active node in the cluster.

    Workaround

    : Address the issues that made the Manager unavailable. You can now connect to the original second Manager.

  • CFY-6906 – This issue relates to the situation in which you have created a cluster from an image and you are joining a second Manager, which was bootstrapped to the cluster. When you join the second Manager to the cluster and run cfy –version, the version list incorrectly shows that you are connect to the bootstrapped (passive) Manager. If you run cfy cluster node list, the list correctly shows the active Manager as being active and that you are connected to it.
  • CFY-6868 – This issue occurs when upgrading from an earlier version to a later version. If you bootstrap a Manager and start a cluster, then tear down the Manager, and bootstrap a new Manager, when you attempt to start a cluster on the new Manager, an error message is returned.
  • CFY-6859 – If you have a cluster of two Cloudify Manager instances and you remove the active Manager, when you join a third Manager to the cluster (of which the second instance is now the active Manager), an internal server error is returned.
  • CFY-6813 – This issue relates to the situation in which you have created a cluster and have then torn down that active Manager. If you use the CLI to switch back to a profile that includes the recently torn down Manager, you erroneously receive a message that the Manager cannot be used because there is no active node in the cluster.
  • CFY-6822 – This issue relates to the situation in which you have two Managers in a cluster. If you remove the passive Manager from the cluster, and then remove the active Manager, you can still upload a blueprint and create resources on what was the active Manager, even though it is now outside of the cluster. If you attempt to start a new cluster with this Manager, or to join it to another cluster, an error message is returned informing you that the Manager is already part of a cluster, even though the cluster node list is empty.
  • CFY-7019 – When you are uploading a plugin to a Manager in a cluster, instead of the plugin upload confirmation message, you erroneously get a message that there was a timeout in the process.
  • CFY-6821 – You can join a Manager that already has resources (users, tenants, or plugins) on it to a cluster and set it as the active Manager, although a Manager should be clean before it can be joined to a cluster.

Cloudify Composer

  • In the blueprints catalog on the Imports tab, the default types.yaml file is located in the http://www.getcloudify.org/spec/cloudify/4.1m2/types.yaml directory. There are no changes to the functionality of the YAML file.
  • In the out-of-the-box catalog, the OpenStack plugin is not included. You can add it by clicking Import and entering the link to the appropriate plugin. To identify the correct link, open the Cloudify downloads page.
  • You cannot add an output using Cloudify Composer. Open the blueprint in a text editor and add the output directly in the blueprint.
