Deploying Apps to Shared Spaces

You deploy apps to a shared space using Runtime Manager.

CloudHub 2.0 supports Mule runtime engine versions 4.3.x and later. Mule 3.x is not supported.
Runtime Manager doesn’t support deploying an application to CloudHub 2.0 or Runtime Fabric if the asset was previously soft-deleted in Exchange.

Deploy an App to a Shared Space

  1. From Anypoint Platform, select Runtime Manager > Applications.

  2. Click Deploy application.

  3. On the Deploy Application page:

    1. Enter the name of the application.

      You cannot change the name of an app after you deploy it. To change the name, you must delete and redeploy the app using the new name.

    2. Select an application file:

      • To upload a Mule app JAR file from your system, select Choose file > Upload file.

      • To choose an example app from Anypoint Exchange:

        1. Select Choose File > Import file from Exchange.

        2. In the Get from Exchange page, enter hello in the Search assets by name:

          Get from Exchange page

        3. Click Hello World and then click Select.

    3. Select CloudHub 2.0, and then Shared Space for the region from the Deployment Target list.

      For the list of regions, see Shared Global Regions. If you have the global deployment entitlement, all regions are available. If you have region restrictions based on your subscription, only regions that are available to your organization appear.

    4. Configure options for deployment:

  4. Click Deploy Application.

Specify Runtime Options

Click the Runtime tab and specify the following options:

Runtime version

Specifies the Mule runtime engine version. Versions 4.3.x, 4.4.x, 4.5.x, and 4,6.x are supported.

Release Channel

Starting with Mule 4.5, MuleSoft introduces two new release channels, Edge and Long-term Support (LTS).

For new applications, the Edge channel is selected by default in the Release Channel drop-down menu.

For existing applications using a legacy version, the Release Channel drop-down list is selected as None by default. Use the Release Channel drop-down list to select the desired release channel.

For existing applications using an Edge version, the Release Channel drop-down list is selected as Edge. The Runtime Version dropdown list indicates if there is an update available, as well as the previous and latest version of the application. Use the Release Channel drop-down list to change to a legacy version.

For existing applications using an Edge or an LTS version on extended support, a warning message appears indicating the version’s EOL.

After End of Extended Support for Mule runtime 4.3 and 4.4, Mule applications deployed to CloudHub or CloudHub 2.0 environments are stopped.
Java Version

Select the Java version for your application. For more information, visit Java Support.

Replica size

Specifies the number of vCores in the replica to run your application.

For information on replica sizes, memory, and storage, see CloudHub 2.0 Replicas. CloudHub 2.0 limits the replica size per deployment to four vCores.

Replica Count

Specifies the number of replicas, or instances, of the application to deploy.

A minimum of two replicas is required for high availability.

Run in Runtime Cluster Mode

Enables Mule clustering across each replica of the application.

This option requires at least two replicas.

Use Object Store V2

You can select Object Store v2 as the implementation for Mule 3 and Mule 4 by checking the Use Object Store V2 checkbox.

Deployment model

  • Rolling update:

    • Maintains availability by incrementally updating replicas.

  • Recreate:

    • Terminates replicas before redeployment.

    • Redeployment is faster and doesn’t require additional resources.

Application Names

The application name you specify can contain between 3 and 42 alphanumeric characters (a-z, A-Z, 0-9) and dashes (-). They cannot contain spaces or other characters. The application name must start with a letter (a-z or A-Z). It cannot start with a number or dash and it cannot end with a dash.

To ensure that names are unique and avoid domain conflicts, CloudHub 2.0 adds a six-character unique-id to the application name that you specify in the public endpoint URL.

The application name identifies your application not only in Runtime Manager but also in the public cloudhub.io domain. For example, an application named myapp is accessible at http://myapp-unique-id.shard.usa-w2.cloudhub.io. You must have unique application names for each deployment target.

To further customize your app names, you can create a naming convention. For example, you could prepend your company name and department to all application names, such as mycompany-mydept-myapp. You can then add DNS records to hide the complex application name. For example, you might route requests to myapp.mycompany.com to mycompany-mydept-myapp-unique-id.shard.region.cloudhub.io.

Make application file names as unique as possible. An app cannot be deployed if it shares the same name as an asset in Exchange.

Change App Behavior with Properties

You can configure property values, such as specifying the environment or setting passwords and usernames, during app deployment.

For information about configuring app properties, see:

Configure Logging for the App

Logging is enabled by default for apps deployed to CloudHub 2.0.

Disable or Enable Logging

To disable or reenable logging for the app:

  1. Click the Logging tab.

  2. Deselect or select the Forward application logs to Anypoint Platform option.

  3. Click Apply Changes.

If you disable logging, the Logs heading still appears in the Runtime Manager navigation menu, but application logs are not collected.

Configure Log Levels and Categories

To configure additional log levels and categories to include in logs:

  1. Click the Monitoring tab.

  2. Select the log level:

    • INFO: Informative messages

    • DEBUG: Debugging messages

    • WARNING: Warning messages

    • ERROR: Error messages, such as when an exception occurs

    • FATAL: Fatal messages for when an application fails

  3. Optionally, set the log level for specific a Java package class by selecting the log level, entering the package.name, and pressing the Enter key.

  4. Click Apply Changes.

Changing the log level and clicking Apply Changes restarts the application.

Enable Trace Data Collection

This feature is available only if your organization has the Anypoint Integration Advanced package or a Titanium subscription to Anypoint Platform. For more information, see the Pricing and Packaging documentation.

Traces enable you to understand the path of a transaction in the MuleSoft ecosystem by providing full visibility into the execution path of API calls or application transactions. When you enable trace data collection for an app, Anypoint Platform collects and exposes tracing information from Mule runtime engine in the OpenTelemetry standard, enabling you to export it using the Anypoint Monitoring Telemetry Exporter.

You can enable trace data collection for your CloudHub 2.0 applications running on Mule version 4.6 or later. You can’t enable trace data collection using the Mule Maven plugin, Anypoint CLI, or Anypoint Studio. You can enable trace data collection using only the UI and API.

To enable trace data collection for an app:

  1. Click the Monitoring tab.

  2. Select the Enable tracing checkbox.

  3. Click Deploy Application if you are enabling the feature for a new deployment, or Apply Changes if you are editing an existing application.

Once you enable tracing, and redeploy your application, the Runtime Manager backend starts instrumenting traces for your application.
