Please refer to the kube-scheduler implementation in Example: Let us understand this by a very general example, suppose, we search for www.google.com in your web browser then this will be a request which will be sent from system to the google`s server to serve that webpage, now the request is nothing but a stream of packets don`t just go the google`s server straightaway they go through a series of devices known as a router which accepts this packets and forwards them to correct path and hence it reaches to the destination server. Articles about SSRF attacks: Part 1, part 2 and part 3. If you want to provide your own service account for blob storage instead of using a generated service account, add the following to your terraform.tfvars file: create_blobstore_service_account_key = false Step 4: Create GCP Resources with Terraform. verify that the pods were scheduled by the desired schedulers.

For more details, please read the GCR A generic router consists of the following components: Below is the raw diagram showing the internal components of the router: The router is an intelligent device, routers use routing algorithms such as Dijkstras Algorithm to map the destination or to find the best route to a destination on the parameters like the number of hops. Thanks for the feedback. Regarding the proof of legitimacy of the request: The TargetedApplication that will receive the request must generate a random token (ex: alphanumeric of 20 characters) that is expected to be passed by the caller (in body via a parameter for which the name is also defined by the application itself and only allow characters set [a-z]{1,10}) to perform a valid request. nodes for the level of resource demand in your cluster.
