Deploying Apps to CloudHub 2.0

You can deploy Mule apps to either a shared or private space in CloudHub 2.0.

CloudHub 2.0 supports Mule runtime engine versions 4.3.x, 4.4.x, 4.5.x. Mule 3.x is not supported.

Application Deployment

After triggering a deployment, the application status eventually changes to RUNNING. If the application status never changes to RUNNING, the replicas contain a state and reason to indicate why the application status is not RUNNING.

When an application is deployed, the following events occur:

  1. The expected state of your application is stored, including application bundle and number of replicas.

  2. The application replica status is PENDING.

  3. When adequate compute and memory resources are available, each replica is attached to a node.

  4. The replica status is STARTING.

  5. The replica finishes loading the application.

  6. The replica status is STARTED and the replica can now perform work.

Application Deployment Failure

If an application fails, for example, due to running of out memory, the following events occur:

  1. The replica status is TERMINATED.

  2. CloudHub 2.0 immediately attempts to restart the replica.

  3. The replica status is RECOVERING.

If the replica is able to restart:

  1. The replica finishes loading the application.

  2. The replica status is STARTED and the replica can now perform work.

If the replica can’t restart, for example, it relies on a network resource which temporarily unavailable, the following events occur:

  1. The replica status is PENDING, with a message indicating "CrashLoopBackoff".

    CloudHub 2.0 attempts to restart the replica, using exponential backoff to avoid an excessive number of restart attempts.

  2. The replica status alternates between RECOVERING and PENDING until the issue preventing a successful restart is resolved.

  3. The replica loads the application.

After a successful restart, the replica status is STARTED and the replica can now perform work.
