Configuring Your Network to Support Runtime Fabric on Self-Managed Kubernetes
|
Network configuration must be performed by an IT administrator. |
Before installing or using Runtime Fabric on Self-Managed Kubernetes, ensure that the following ports and hostnames are configured correctly.
Port Configuration
To install or run Runtime Fabric, ensure that you have configured the following ports on your Kubernetes installation.
For protocol-aware firewalls, consider allowing the following port traffic to use AMQP (Advanced Message Queuing Protocol) over Websockets.
|
The following table does not include ports and hostnames from Anypoint Platform that you may also need to allow. Refer to the Anypoint Mule Gateway documentation for a list of additional ports and hostnames. |
| Port | Layer 4 Protocol | Layer 5 Protocol | Source | Destination | Description |
|---|---|---|---|---|---|
443 |
TCP |
HTTPS |
API consumers |
All nodes |
Allow inbound API requests to ingress controllers |
443 |
TCP |

All nodes |
Internet |

Anypoint Monitoring, Anypoint Visualizer |
Port Used by the Persistence Gateway
The Persistent Gateway requires a Postgres-compliant database to store persistent data across Mule application replicas. Ensure that your Kubernetes cluster has access to this database and port. See Persistence Gateway.
Hostname Configuration
To function correctly, Runtime Fabric on Self-Managed Kubernetes requires the following hostname configurations:
| Port | Protocol | Hostnames | Description |
|---|---|---|---|
443 |
AMQP over WebSockets |
|
Runtime Fabric message broker for interaction with the control plane. |
443 (v1.8.50 and later) |
TCP (Lumberjack) |
|
Anypoint Monitoring agent for Runtime Fabric. |
5044 (legacy) |
TCP (Lumberjack) |
|
Anypoint Monitoring agent for Runtime Fabric. As of Runtime Fabric version 1.8.50, this port is not strictly required. It will be deprecated in the future. |

Verify Outbound Connectivity
Every Anypoint Runtime Fabric cluster requires connectivity with Anypoint control plane, and any interference with connectivity can limit functionality, resulting in application deployment failures or degraded status in Anypoint Runtime Manager.
You can use rtfctl to verify that Runtime Fabric has the required outbound connectivity. On each node, follow the instructions in Install rtfctl to install rtfctl.
To verify the required outbound connectivity, run the following command on all controller and worker nodes in the cluster:
sudo ./rtfctl test outbound-network
Sample output:
[root@rtf-controller-1 runtimefabric]# sudo ./rtfctl test outbound-network Using proxy configuration from Runtime Fabric (proxy "", no proxy "") Using 'US' region transport-layer.prod.cloudhub.io:443 ✔ https://anypoint.mulesoft.com ✔ https://worker-cloud-helm-prod.s3.amazonaws.com ✔ https://exchange2-asset-manager-kprod.s3.amazonaws.com ✔ https://ecr.us-east-1.amazonaws.com ✔ https://494141260463.dkr.ecr.us-east-1.amazonaws.com ✔ https://prod-us-east-1-starport-layer-bucket.s3.amazonaws.com ✔ https://runtime-fabric.s3.amazonaws.com ✔ tcp://dias-ingestor-nginx.prod.cloudhub.io:443 ✔
If you have outbound connectivity issues that prevent Runtime Fabric from reaching any of the required Anypoint control plane services, work with your network team to verify that you have added the required port IPs and hostnames to the allowlist as described in the port configuration section.
Certificate Configuration
To allow different endpoints to use mutual TLS authentication to establish a connection, you must configure SSL passthrough to allow the following certificates:
| Control Plane | Certificates |
|---|---|
US control plane |
|
EU control plane |
