QUESTION
I originally posted this question as an issue on the GitHub project for the AWS Load Balancer Controller here: https://github.com/kubernetes-sigs/aws-load-balancer-controller/issues/2069.
I'm seeing some odd behavior that I can't trace or explain when trying to get the loadBalacnerDnsName from an ALB created by the controller. I'm using v2.2.0 of the AWS Load Balancer Controller in a CDK project. The ingress that I deploy triggers the provisioning of an ALB, and that ALB can connect to my K8s workloads running in EKS.
Here's my problem: I'm trying to automate the creation of a Route53 A Record that points to the loadBalancerDnsName
of the load balancer, but the loadBalancerDnsName
that I get in my CDK script is not the same as the loadBalancerDnsName
that shows up in the AWS console once my stack has finished deploying. The value in the console is correct and I can get a response from that URL. My CDK script outputs the value of the DnsName as a CfnOutput value, but that URL does not point to anything.
In CDK, I have tried to use KubernetesObjectValue
to get the DNS name from the load balancer. This isn't working (see this related issue: https://github.com/aws/aws-cdk/issues/14933), so I'm trying to lookup the Load Balancer with CDK's .fromLookup
and using a tag that I added through my ingress annotation:

Answered 2021-Jun-13 at 20:23I think that the answer is to use external-dns.
ExternalDNS allows you to control DNS records dynamically via Kubernetes resources in a DNS provider-agnostic way.
QUESTION
I want to render data
object in the body
as a table with three columns
one for the key
like "ASIANPAINT24JUN21FUT"
and other two for the links
I don't have any experience with javascript, I tried using renderjson
to render the
json object received, but it renders just plain text,
I want to render the object as a table, and the links in it should be clickable
How can I achieve this?
index.html
...ANSWER
Answered 2021-Jun-11 at 05:02to do this you should modify the dom using javascript, here the documentation about html5 tables https://developer.mozilla.org/en-US/docs/Web/HTML/Element/table, about links https://developer.mozilla.org/en-US/docs/Web/HTML/Element/a, and i am pretty sure you will also need this https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/keys, using this and some kind of bucle like a foreach, a map or a for, you can access the object info in a dynamic way, also if you need it you have some documentation about dom manipulation https://developer.mozilla.org/en-US/docs/Web/API/Document_Object_Model/Introduction, maybe you also find useful methods like document.getElementById

QUESTION
I have a spring boot 2.5 application with spring spring security 5 where I am using embedded hazelcast cache to back spring sessions. This application is deployed on openshift with two pods where same application is running, hence I have used hazelcast kubernetes plugin for service discovery. Everything is working as expected. However, I can see application logs are flooded with below log lines. Any suggestion what is wrong with the hazelcast configuration ? Why so many log lines are generated ?
Generated logs
10.1.8.58 is IP address of second pod which joined cluster later and logs are printed in this pod only.
...ANSWER
Answered 2021-Jun-07 at 07:29The exception you get SplitBrainMergeValidationOp
means that the Hazelcast cluster might have been started in the split-brain and later tries to merge into one cluster. Could you check if you follow all the Hazelcast Kubernetes recommendations?
Especially, check if you use StatefulSet (not Deployment). In the case of DNS Lookup discovery, using Deployment may cause Hazelcast to start in the split-brain mode.
QUESTION
I'd like to setup some monitoring for capturing access denied and unauthorized operation errors in my AWS account. I'd like to capture all of these events across different AWS services but have run into some issues. I've initially setup some a couple of cloud watch rules that trigger a basic lambda function but I'm not capturing the events I'm looking for. Below are a couple of the rules events that trigger a Lambda function (ideally I'd filter these down from capturing all events once I get this working).
...ANSWER
Answered 2021-Jun-02 at 00:49aws dynamodb list-tables
, aws ec2 describe-instances
and List item
do not work because List*
, Get*
and Describe*
API events are not supported by CloudWatch Events:
If you want to capture such events, you have to do it through CloudWatch Logs. Namely, setup your CT trail to push events to CloudWatch Logs. Then, setup a subscription filter to your lambda. This will push all API events to your lambda through CloudWatch Logs. Subsequently, you will be able to detect AccessDenied
errors in the events and perform other actions you require.
Other possibility would be to setup metric filter on the logs so that AccessDenied
errors are captured to create a CloudWatch metric. Then you setup a CloudWatch Alarm based on the metric. This will trigger an alarm, but it will not pass the details of event that triggered the alarm to your function. You will only know that access denied happened, but without further details.
Update
create-table
works as expected. I used the following rule in my tests which I hooked up to SQS for quick checks:

Okay, the title is quite mouthful. But it's actually describing the situation.
I deployed a service on GKE in namespace argo-events. Something was wrong with it so I tore it down:
...ANSWER
Answered 2021-May-28 at 06:01By using command $ kubectl get all
you will only print a few resources like:
- pod
- service
- daemonset
- deployment
- replicaset
- statefulset
- job
- cronjobs
It won't print all resources which can be found when you will use $ kubectl api-resources
.
Example
When create PV
from PersistentVolume documentation it won't be listed in $ kubectl get all
output, but it will be listed if you will specify this resource.
QUESTION
We have an Apache Flink POC application which works fine locally but after we deploy into Kinesis Data Analytics (KDA) it does not emit records into the sink.
Used technologies Local- Source: Kafka 2.7
- 1 broker
- 1 topic with partition of 1 and replication factor 1
- Processing: Flink 1.12.1
- Sink: Managed ElasticSearch Service 7.9.1 (the same instance as in case of AWS)
- Source: Amazon MSK Kafka 2.8
- 3 brokers (but we are connecting to one)
- 1 topic with partition of 1, replication factor 3
- Processing: Amazon KDA Flink 1.11.1
- Parallelism: 2
- Parallelism per KPU: 2
- Sink: Managed ElasticSearch Service 7.9.1
- The
FlinkKafkaConsumer
reads messages in json format from the topic - The jsons are mapped to domain objects, called
Telemetry
ANSWER
Answered 2021-May-18 at 17:24According the comments and more information You have provided, it seems that the issue is the fact that two Flink consumers can't consume from the same partition. So, in Your case only one parallel instance of the operator will consume from kafka partition and the other one will be idle.
In general Flink operator will select MIN([all_downstream_parallel_watermarks])
, so In Your case one Kafka Consumer will produce normal Watermarks and the other will never produce anything (flink assumes Long.Min
in that case), so Flink will select the lower one which is Long.Min
. So, window will never be fired, because while the data is flowing one of the watermarks is never generated. The good practice is to use the same paralellism as the number of Kafka partitions when working with Kafka.
QUESTION
I wish to create an AWS CloudWatch Event rule for S3 create events, in a specific bucket and prefix. Since CloudWatch does not support wildcards, I am instead trying to give the prefix explicitly as in the following example: Does AWS CloudWatch Events Rule supports any wildcards in S3 bucket/key names
(for obfuscation I provide the bucket and prefix names here as my-data-bucket
and my-data-prefix/
)
My JSON rule:
...ANSWER
Answered 2021-May-11 at 09:37Your event is invalid in CloudWatch Events (CWE) rule, but should be fine for CWE replacement, i.e. AWS EventBridge (EB). Thus I would recommend using EB for that event.
EB is basically a new version of CWE, so you can do same thing.
