create status confirmation

Posted by tzul at 2020-02-17

The Google cloud platform (GCP) provides a state to confirm whether the VM's live response is correct. This document describes how to verify and use the state of the load spreader.

This page is used to validating the state concept, targeting users who understand the rules of the GCP firewall.

Status confirmation category, protocol, port

GCP performs status verification based on category and protocol.

There are two types of confirmation status: confirmation status and status before confirmation. Port specification means used in protocol sets and status acknowledgments of each category.

Most load dispersers use the unacknowledged state, but for the network load disperser, the previous state confirmation is needed. On the status confirmation concept page, refer to status confirmation to confirm the appropriate category, protocol and port assignment method.

The protocol selected to confirm the status does not need to match the protocol used in the load spreader, so it is impossible to match. Please refer to the protocol and load divider for details.

The term "confirmation status" refers to the confirmation without displaying the previous status. It is explicitly mentioned in this document that the previous status confirmation is "confirm previous status".

Create status confirmation

With GCP, you can select the status and selection when completing the back-end composition of load dispersion period in GCP console.

In GCP console, different state acknowledgments can be formed with load dispersion period. This is the case where the status needs to be confirmed first or the use status of the multi load disperser needs to be confirmed. You can create states using GCP console, gcloud command-line tools, or rest APIs. After checking the background information of this sector, it will enter the confirmation status and modification.

gcloud gcloud

The network load disperser must use the back-end composition or selected state in GCP console to complete the network load disperser period. If you want to create the previous state separately, you must use the gcloud command-line tool or the rest API. Please refer to the previous status for details.

gcloud gcloud

Flag to confirm all States

The next flag has nothing to do with the protocol and confirms all States together.

The meanings are as follows.

ssl tcp 5s 5s 2

Port slogan

To confirm the status, specify the port in addition to the protocol. The way to specify the port is based on the type of load dispersion period and the type of back-end used by the back-end service. The following table shows the port options for the combination of the payload disperser and backend. On the table, the term "Internship combination" means non management type instant combination, management type instant combination, or management type field avatar combination.

Only one type of port can be used for acknowledgment status.

--port 1 65535 --port-name --use-serving-port --port 1 65535 --use-serving-port --port 1 65535 --port-name --use-serving-port

1 Port specification combination will be resolved as follows.

--use-serving-port --port --port-name --port --port-name --port --port=80 --use-serving-port --port --port-name --port --port-name --port --port=80

2 beta: --- the beta gcloud instruction must be used when the use serving port requires it.

--use-serving-port gcloud --use-serving-port gcloud
