Manage Proxies on Runtime Fabric on Self-Managed Kubernetes

Runtime Fabric on Self-Managed Kubernetes uses two types of proxies when running and hosting applications:

  • System proxies: include proxies that enable connectivity among Kubernetes cluster services, including the Docker daemon and other internal components. When using Runtime Fabric on Self-Managed Kubernetes you are responsible for configuring and managing system proxies.

  • Application proxies: include proxies that enable connectivity to applications running on Runtime Fabric.

Install rtfctl

The rtfctl command line tool is required to manage proxy settings on Runtime Fabric. Follow the steps to Install rtfctl before configuring proxy settings.

You must install Runtime Fabric before running rtfctl apply proxy commands.

Apply Proxy Values to Runtime Fabric on Self-Managed Kubernetes

Configure a proxy at the runtime level for all the outbound components running in the runtime to use.

  1. Run the following command, replacing the placeholder values with the following:

    rtfctl apply http-proxy "http://<user>:<pass>@<10.0.0.1>:<8080>" --no-proxy "<1.1.1.1:8888,2.2.2.2:9999>"

    • <user>: the username needed to authenticate to the HTTP proxy.

    • <pass>: the password needed to authenticate to the HTTP proxy.

      The password must be URL encoded.

    • <10.0.0.1>: Specifies the IP address or hostname to access the HTTP proxy.

    • <8080>: Specifies the port on the host where the HTTP proxy is listening for requests.

    • <1.1.1.1:8888,2.2.2.2:9999>: Specifies the RTF_NO_PROXY hosts and ports, delimited by commas.

    • (Optional) --confirm: Skips manual acknowledgement of the change. If not specified, the rtfctl apply proxy command prompts you to confirm the change before continuing.

  2. To verify the change was successful, run the following command to output the current value of the HTTP proxy:

    rtfctl get http-proxy

    The output should match the value expected.

  3. To remove the remove the proxy values, run:

    sudo /opt/anypoint/runtimefabric/rtfctl apply http-proxy '' --no-proxy ''

Configure a Proxy for the API Manager Agent

You can use a proxy to establish communication for Mule applications that you manage with API Manager. This proxy configuration must be set on each Mule application, even if you are using the same configuration for all applications. Note this setting is independent from the application-level proxy that applications use to communicate with other external endpoints, as explained in Configure a Proxy for a Mule Application.

anypoint.platform.proxy_host=hostname
anypoint.platform.proxy_port=port
anypoint.platform.proxy_username=username
anypoint.platform.proxy_password=password

Configure a Proxy for a Mule Application

Applications deployed in Runtime Fabric do not inherit proxy settings from the Runtime Fabric cluster. You must configure a proxy for each application.

You can set up a proxy on each connector (such as an HTTP requestor) or set up a proxy with application properties as shown in the following example. Setting up a proxy with application properties is less work if you have a large number of connectors in an application.

http.nonProxyHosts=localhost|*.svc.cluster.local|*.monitoring.svc.cluster.local
http.proxyHost=172.19.0.23
http.proxyPort=3128
https.proxyHost=172.19.0.23
https.proxyPort=3128

java.net.useSystemProxies=false
com.ning.http.client.AsyncHttpClientConfig.useProxySelector=false
com.ning.http.client.AsyncHttpClientConfig.useProxyProperties=true
