Cloudhub 2.0 Deployment Through Maven In Mule

Author: Payal Jain

Introduction:

CloudHub 2.0 simplifies the deployment and running of the MuleSoft application in a containerized environment, based on the Kubernetes. It provides for deployments across 12 regions globally.

Why Cloudhub 2.0:

• There is no need to manage a dedicated load balancer as CloudHub 2.0 provides a built-in Ingress load balancer with auto-scaling capabilities in the private space.
• We have the option to configure inbound and outbound firewalls. This enables us to block or allow traffic from specific ports.
• We are provided with built-in security policies that secure the services and sensitive data with encrypted secrets.
• Cloudhub 2.0 vs Cloudhub 1.0-

	CloudHub 1.0	CloudHub 2.0
Provision/Scaling	Supported	Supported
URL rewriting	Support (DLB)	Supported (app-level)
Load Balancer Logs	Not supported	Supported (download)
Multiple custom endpoints	Partially Supported	Supported
Multiple truststores (client certificates for mutual TLS)	Not supported	Supported
Direct Connect/VPC Peering	Supported (not self-serve)	Not Supported
VPC/VPN/Transit Gateway	Supported	Supported (private spaces)
Outbound firewall rules	Not supported	Supported
Log forwarding	Supported (per app)	Supported (per app)
Custom notifications (CloudHub Connector)	Supported	Not Supported

• Implementation steps needed in pom.xml for deployment are as follows-

1. In the Mule project, in pom.xml we need to make sure our Mule maven plugin version is 3.7.1 or above for deployment to CloudHub 2.0.
2. We must also add the necessary “configuration” details for CloudHub 2.0 in the pom.xml file.

<mule.maven.plugin.version>3.7.1</mule.maven.plugin.version>

<configuration>
	<cloudhub2Deployment>
		<uri>https://anypoint.mulesoft.com</uri>
		<provider>MC</provider>
		<environment>Sandbox</environment>
		<target>Cloudhub-US-East-2</target>
		<username>${anypoint.username}</username>
		<password>${anypoint.password}</password>
		<applicationName>cloudhub2-test</applicationName>
		            <businessGroupId>**********-e628</businessGroupId>
		<replicas>1</replicas>
		<vCores>0.1</vCores>
	</cloudhub2Deployment>
	<classifier>mule-application</classifier>
</configuration>

3. We can publish to Exchange through Anypoint Studio with Project Type set to Example.

4. We can verify this from Exchange.

5. Open the command prompt in the project location, where pom.xml is present. Run the below maven command to deploy the application.

mvn clean package deploy -DmuleDeploy -Danypoint.username=<username> -Danypoint.password=<password>

6. This shall give us Build Success and we can check the Running status in Runtime Manager on the Anypoint platform.

NOTE: Common Issues faced during deployment –

• GAV could not be retrieved from Exchange – Bad Request

GAV stands for – GroupId, ArtifactId, VersionId.

Resolution – The publish to Exchange step is necessary for Cloudhub 2.0 Deployment.

• Configuration is invalid while building-

Resolution: Check for Mule maven plugin version to be 3.7.1 or higher version.
