Description Kathryn Alexander 2019-04-03 19:56:48 UTC
Description of problem: Several of the objects in the 02_cluster_infra.yaml template contain static name parameters that make it impossible to deploy another stack without modifying the template.


How reproducible:

Steps to Reproduce:
1. Deploy the infra template.
2. Deploy the infra template again to a different stack.

Actual results:
Stack deployment fails and is rolled back because the InternalServiceTargetGroup already exists:


            "StackId": "arn:aws:cloudformation:us-east-1:269733383066:stack/kalexanddns1/36628930-563a-11e9-8556-0ee7d31f28a0",
            "EventId": "InternalServiceTargetGroup-CREATE_FAILED-2019-04-03T17:59:28.072Z",
            "StackName": "kalexanddns1",
            "LogicalResourceId": "InternalServiceTargetGroup",
            "PhysicalResourceId": "",
            "ResourceType": "AWS::ElasticLoadBalancingV2::TargetGroup",
            "Timestamp": "2019-04-03T17:59:28.072Z",
            "ResourceStatus": "CREATE_FAILED",
            "ResourceStatusReason": "InternalServiceTargetGroup already exists in stack arn:aws:cloudformation:us-east-1:269733383066:stack/KatherineClusterInfra/aec15820-4a4b-11e9-afb3-0e7f598ae3ee",
            "ResourceProperties": "{\"VpcId\":\"vpc-005b5b485342f7bba\",\"Port\":\"22623\",\"TargetType\":\"ip\",\"TargetGroupAttributes\":[{\"Value\":\"60\",\"Key\":\"deregistration_delay.timeout_seconds\"}],\"Protocol\":\"TCP\",\"Name\":\"InternalServiceTargetGroup\"}"


Stephen has a fix for the template.

The PR is merged, so move this bug to ON_QA.

Comment 3 Johnny Liu 2019-04-04 08:24:27 UTC
Verified this bug with latest template, and passed.

Now target group are created with some random string in their name, when I am using 'jialiuuuuu2' as cluster name, those target group would something like:
jiali-Exter-R8T1T135WFIA
jiali-Inter-1J81P3GSGHXLM
jiali-Inter-1SGXWMUVV1F0Q
