kandi X-RAY | eventsource Summary

eventsource is a Go library typically used in Serverless, DynamoDB applications. eventsource has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

eventsource is a Serverless event sourcing library for Go that attempts to leverage the capabilities of AWS to simplify the development and operational requirements for event sourcing projects. This library is still under development and changes to the core api are likely. Take advantage of the scalability, high availability, clustering, and strong security model you've come to know and love with AWS. Serverless and accessible were significant design considerations in the creation of this library. What AWS can handle, I'd rather have AWS handle.

            AWS Load Balancer Controller successfully creates ALB when Ingress is deployed, but unable to get DNS Name in CDK code
            Asked 2021-Jun-13 at 20:44

            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:

            I 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.

            to 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

            Asked 2021-Jun-07 at 07:29

            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.

            The 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.

            AWS configure cloud watch/trail to monitor for 'AccessDenied' and 'UnauthorizedOperation' errors
            Asked 2021-Jun-02 at 00:49

            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).

            Answered 2021-Jun-02 at 00:49

            aws 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:

            By 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.

            Answered 2021-May-18 at 17:24

            According 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.

            Your 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.
