Ingress object

As explained in Google Anthos in Action

Ingress is a Kubernetes API resource that defines rules for routing external HTTP and HTTPS traffic to services.

An ingress object is a Kubernetes API resource that defines rules for routing external HTTP and HTTPS traffic to services. In Anthos, Ingress is also an enableable fleet feature managed through the Google Cloud console, gcloud, or the fleet management API. section 2.4.5 section 7.3

Deployment implications include:

• Use Ingress to expose services to internet clients while defining how external requests reach cluster services. section 7.3
• Treat Anthos Ingress as a fleet-level capability that administrators can enable or disable centrally. section 2.4.5
• For hybrid multicloud applications, account for the limitation that Anthos Ingress clusters must run on Google Cloud; Traffic Director can route to applications across private and public clouds. section 7.3

Anthos feature enablement

An administrator opens the Features menu to review Ingress across the fleet, then enables or disables it in the console or uses the generated CLI commands for automation. section 2.4.5

How Google Anthos in Action covers it

How deep it goes

Defines the routing role and Anthos deployment limitation but does not provide manifest syntax or controller internals.

Examples

Uses the Anthos Features menu and Traffic Director as operational examples.

What you can do after

Operate/configure Ingress through the Google Cloud console, gcloud, or fleet management API.

How it connects

Connects Kubernetes API resources, services, Anthos, Traffic Director, and hybrid multicloud architecture.
