Fix part one: the health-check. An improvement would be to use a different endpoint (e.g. The following targets should be used for the health status checks by the ELB: It blamed the app-server and removed it from the target group. For each ELB, you will have defined Target groups (see the KB above).

Create a target group that will be attached to the ALB and route traffic from ALB to your container instances. Screenshot: Health registered ec2 instance in target group Terraform v0.11.1. A Target Group health check protocol can be changed between HTTP and HTTPS, but changing it to or from TCP should trigger a recreation plan for the Target Group. draining An Amazon S3 bucket where we will store information such as ALB IP addresses. Once a target group has been created, only its health check can then be modified using subsequent calls; If parameters are not set within the module, the following environment variables can be used in decreasing order of precedence AWS_URL or EC2_URL, AWS_ACCESS_KEY_ID or AWS_ACCESS_KEY or EC2_ACCESS_KEY, AWS_SECRET_ACCESS_KEY or AWS_SECRET_KEY or EC2_SECRET_KEY, AWS… Health check HTTPS Path : /healthy.html Port 443 Healthy threshold : 10 Screenshots:-Task event logs-Unhealthy regitered ec2 instances in target group. 4. An IP-address-based target group for the NLB (target group protocol is TCP).

The LB target group health check matcher default value has changed from versions 1.2 of aws provider to 1.3.0 of the aws provider. Terraform Version. tags - (Optional) A map of tags to assign to the health check. (See Appendix A.) The first problem was that the health-check required a response from the database. provider.aws v1.7.0; Affected Resource(s) aws_lb_target_group; Expected Behavior. If the database was responding too slowly, the app-server health check would fail. » Attributes Reference The following attributes are exported in addition to the arguments listed above: id - The id of the health check » Import Route53 Health Checks can be imported using the health check id, e.g. The target did not respond to a health check or failed the health check.
# Var Declaration target_groups: - name: test vpc_name: test protocol: https port: 443 health_check_path: /server successful_response_codes: " 200 " target_instances: - test target_port: 443 state: present An IAM role that has an IAM policy that allows AWS Lambda to create the resources for us. The target is not registered with a target group, the target group is not used in a listener rule for the load balancer, or the target is in an Availability Zone that is not enabled for the load balancer. My configuration is as follows : Target Group WebInstancesHttps HTTPS through port 443 . Note: If change my Host port to 10440 also, the set-up works fine. Each of these Target Groups has a Health Checks tab which you can edit, for example: Solution.

5. You need to define port & protocol that ALB uses to route traffic to your targets in your target group and perform health checks on your targets (Instances). But my task are keep on terminating due to failing health check. This is where the AWS Lambda function glues the ALB to the NLB. Note. At least one of either fqdn or ip_address must be specified. I have completed my AWS ELB architecture for our website and successfully created the Launch Configuration and Target Groups for which instances are created behind the Load Balancer. unused. You can resolve this failed health status issue by adding a index.html file on your default wamp path and then check your instance health status in your target group and configure your heath checks in target group just like the below one: Protocol:HTTP Path:/ Port:80 File location: c:/wamp64/www/html/ But I cannot run more task than the number of ec2 instance.
