Ansible in git

The git sources for ansible are used by Read the Docs. The source code for the modules is used to generate the module documentation. To submit an update to module docs, you need to change the 'DOCUMENTATION' Metadata in the modules directory of the core source code repository.

Authentication of Load Balancers in the Accessibility Zone

Before the load balancer sends a health check request to a target, you must register it with a target group, specify its target group in a listener rule, and ensure that the Availability Zone of the target is enabled for the load balancer. The initial health checks must be passed before a target can receive requests. The target's status is healthy after it passes the initial health checks.

Deregistering Targets in Elastic Load Bal Ancing

Before a target can receive requests from the load balancer, they must pass initial health checks. Wait for your target to pass the initial health checks and then check its health status again. If a deregistering target has no in-flight requests or active connections, Elastic Load Balancing immediately deregisters.

The initial state of a target is draining. The de registration process is complete after the deregistration delay has ended. If the target is part of an auto scaling group, it can be terminated and replaced.

Adding anything to the target group account

Each target group route requests to one or more registered targets using the protocol and port number that you specify. You can register multiple targets. You can change the health checks on a per target group basis.

Health checks are performed on all targets registered to a target group that is specified in a listener rule for your load balancer. Load balancers don't have instances to route traffic to the empty target group, even though you have set one up. The next step is to create a launch configuration.

You should not add anything to your account. The load balancer and auto scaling group should be deleted first. The launch configuration and security groups should be deleted.

Failure of the Route 53 Health Check

Route 53 marks the alias record as healthy when all the target groups are healthy. The target group health check passes if there is at least one healthy instance. Route 53 returns records according to your policy.

Route 53 returns the record that is least visible from your resolver's location. If any of the target groups in an Application Load Balancer are not healthy, the alias record fails the Route 53 health check. Route 53 returns one of the healthy records.
