(2025.12 and 2025.12.01) Fail to enable QUIC support when no custom tags provided

[Murielxun]

Bug description

Enabling QUIC support fails and deletes the <environment-name>-vdc-external-nlb Load Balancer listener when CloudFormation tags are not provided during deployment.

Affected versions

2025.12 and 2025.12.01

Mitigation

1. (Optional) Recreate the listener of <environment-name>-vdc-external-nlb Load Balancer if it is already deleted

   1. Get the Target Group ARN by replacing <target-group-name> with the name of the <environment-name>-gateway-TN-<suffix> in EC2 Target Groups console and <environment-name> with the name of your RES environment.

   ENVIRONMENT_NAME=<environment-name>
   TARGET_GROUP_NAME=<target-group-name>
   TARGET_GROUP_ARN=$(aws elbv2 describe-target-groups --names ${TARGET_GROUP_NAME} --query "TargetGroups[0].TargetGroupArn" --output text)
   

   2. Get the <environment-name>-vdc-external-nlb Load Balancer ARN

   LOAD_BALANCER_NAME=${ENVIRONMENT_NAME}-vdc-external-nlb
   LOAD_BALANCER_ARN=$(aws elbv2 describe-load-balancers --names ${LOAD_BALANCER_NAME} --query "LoadBalancers[0].LoadBalancerArn" --output text)
   

   3. Recreate the listener

   aws elbv2 create-listener --load-balancer-arn ${LOAD_BALANCER_ARN} --protocol TCP --port 443 --default-actions "Type=forward,TargetGroupArn=${TARGET_GROUP_ARN}"
   

2. Create a S3 bucket with ACLs disabled.

3. Download patch_host.py and idea-cluster-manager-2025.12.01-679477ec.tar.gz by replacing <output-directory> with the directory to download the patch script, <environment-name> with the name of your RES environment, <bucket-name> with the name of a ACLs disabled S3 bucket under the account/region where RES is deploye, RES_VERSION with 2025.12.01, and with Classic or GovCloud in the command below:

   1. The patch applies to 2025.12.01
   2. The patch file requires AWS CLI v2, Python 3.10 or above, and Boto3.
   3. Configure the AWS CLI for the account / region where RES is deployed, and make sure that you have S3 permissions to write to the bucket provided through <bucket-name>.

   OUTPUT_DIRECTORY=<output-directory>
   ENVIRONMENT_NAME=<environment-name>
   RES_VERSION=<RES_VERSION>
   BUCKET_NAME=<bucket-name>
   PARTITION=<partition>
   
   mkdir -p ${OUTPUT_DIRECTORY}
   curl https://research-engineering-studio-us-east-1.s3.us-east-1.amazonaws.com/releases/${RES_VERSION}/patch_scripts/patch_host.py --output ${OUTPUT_DIRECTORY}/patch_host.py
   curl https://research-engineering-studio-us-east-1.s3.us-east-1.amazonaws.com/releases/${RES_VERSION}/patch_scripts/patches/idea-cluster-manager-2025.12.01-679477ec.tar.gz --output ${OUTPUT_DIRECTORY}/idea-cluster-manager-2025.12.01-679477ec.tar.gz
   

4. Run the following patch commands:

python3 ${OUTPUT_DIRECTORY}/patch_host.py --environment-name ${ENVIRONMENT_NAME} --module cluster-manager --zip-file ${OUTPUT_DIRECTORY}/idea-cluster-manager-2025.12.01-679477ec.tar.gz --s3-bucket ${BUCKET_NAME} --partition ${PARTITION}

5. Cycle the Cluster Manager instance for your environment. You may also terminate the instance from the Amazon EC2 Management Console.

INSTANCE_ID=$(aws ec2 describe-instances \
           --filters \
           Name=tag:Name,Values=${ENVIRONMENT_NAME}-cluster-manager \
           Name=tag:res:EnvironmentName,Values=${ENVIRONMENT_NAME}\
           --query "Reservations[0].Instances[0].InstanceId" \
           --output text)

aws ec2 terminate-instances --instance-ids ${INSTANCE_ID}

6. Verify the Cluster Manager instance status by checking the activity of the auto scaling group starting with the name <RES-EnvironmentName>-cluster-manager-asg. Wait until the new instance is launched successfully.
