Kubernetes Cluster: Implementing Ingresses<\/h2>\n

In Kubernetes<\/a>, an Ingress<\/a> serves as a load balancer that facilitates external access to services, offers SSL termination, and supports name-based virtual hosting. It operates based on a set of rules (spec) that are applied to all incoming requests.<\/p>\n

Tip:<\/strong> In comparison to services exposed via NodePort, Ingress presents a more robust yet complex solution. It’s particularly beneficial when you need to expose multiple services under a single IP address. Moreover, Ingress is managed by a controller, which offers a plethora of built-in features such as SSL, authentication, and routing.<\/div>\n
<\/div>\n

By default, Traefik is the ingress controller for managing Ingresses in the Kubernetes Cluster<\/a>, with options like HAProxy and NGINX available in the upcoming 1.15.5 package version. The controller monitors objects, interprets specs\/annotations, and converts them into redirection rules.<\/p>\n

Note:<\/strong> Once the ingress controller is selected during installation, it cannot be changed using Kubernetes management add-ons or other automation tools. However, manual configuration adjustments are still feasible, and our support team is available to assist if needed.<\/div>\n
<\/div>\n

An Ingress spec comprises a path rule, a backend service, and a port. Here’s an example of what your Ingress may look like:<\/p>\n

apiVersion:<\/b> extensions\/v1beta1\r\nkind:<\/b> Ingress\r\nmetadata:<\/b>\r\n\u00a0\u00a0labels:\r\n\u00a0\u00a0\u00a0\u00a0app: myapp\r\n\u00a0\u00a0name: myapp\r\n\u00a0\u00a0annotations:\r\n\u00a0\u00a0\u00a0\u00a0kubernetes.io\/ingress.class: traefik\r\n\u00a0\u00a0\u00a0\u00a0ingress.kubernetes.io\/secure-backends: \"true\"\r\n\u00a0\u00a0\u00a0\u00a0traefik.frontend.rule.type: PathPrefixStrip\r\nspec:<\/b>\r\n\u00a0\u00a0rules:\r\n\u00a0\u00a0- http:\r\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0paths:\r\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0- path: \/myapp\r\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0backend:\r\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0serviceName: myapp\r\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0servicePort: 8080<\/code><\/pre>\n
This example exposes the “myapp” service, which is connected to port 8080, on a path within your Kubernetes environment’s default domain, using the “\/myapp” suffix. This means that the service can be accessed via a URL like https:\/\/${envName}.${platformDomain.com}\/myapp. For further details on configuring ingress rules, including path- and subdomain-based routing, please consult the official documentation<\/a>.<\/p>\n
