but you have used classic load balancer not application load balancer?
just the perfect and the crisp one....thnks...
you saved my day. you made me feel it is just so simple to get started. thanks a ton!
where exactly did you get the added policy from github for Lambda ?From creator of policy ?
After setting up the ingress, I'm unable to retrieve the ingress name (domain).
Thanks for the information....
if you run into the problem of "Error code: InvalidParameterValueException. Error message: The provided execution role does not have permissions to call DeleteMessage on SQS" Follow these instructions: Go to IAM in the AWS Console Click on roles Select your Lambda function execution role or create one if you don't already have Add the AWS managed LambdaSQSQueueExecutionRole policy to the role. The policy contains all the permissions to call the required actions on SQS from Lambda. The ARN of the policy is arn:aws:iam::aws:policy/service-role/AWSLambdaSQSQueueExecutionRole. Save the role, and then try again to add the trigger. This time it will work fine.
Great video Can someone help me understand this statement in the lambda function? domain = os.environ['NAMEOFDOMAIN'] host = "" + es.describe_elasticsearch_domain(DomainName=domain)['DomainStatus']['Endpoint'] How come Domainstatus and endpoint are in ' ' ? Is it being queried by the OS import library?
Pls continue ur videos 🙏
simple and crispy with tones of Experience knowledge. Keep it up !
Can we create sns topic without changing access policy to advanced
Hi there, i have actually run into a problem. when i try to add the lambda trigger into sqs it throws an error message "Error code: InvalidParameterValueException. Error message: The provided execution role does not have permissions to call DeleteMessage on SQS" and i have used the same policy for the sqs as shown in this video. any idea how to solve this?
I have followed the same sequence as mentined in your vedio but still facing below error : InvalidParameterValueException: Cannot access stream arn:aws:dynamodb:us-east-1:<stream-event>. Please ensure the role can perform the GetRecords, GetShardIterator, DescribeStream, and ListStreams Actions on your stream in IAM.
If a loadbalancer is applied, what dns or url should be used to launch the application?
Great Work!! Was looking for similar solution, Due to spefciic requirement, i have elasticsearch 7.10 running on AWS Opensearch service, Have tried above steps getting signature miss match error when i try to access <api url>/<stage_name>/_plugin/kibana, do we need to do some changes to make it compatible with elasticsearch
Thank you, great content 🎉
why is the volume so low ?? rest information is good.
Hi, First of all thank you for provide such helpful content... Everything is working correctly but i wanna know how to add https with the loadbalancer. thx @listentolearn2363

Do we need to create index before uploading the file? I wanted to just insert the data dynamically is this possible? For example. I have a sample json using that I wanted to create an index without creating it manually.
Hi , will this work for prefixes within s3 bucket?
Thanks for the video, would you be able to show the video on how to do this using cloud formation template and how to hit the opensearch domain endpoint and ingest and query data
Hi thanks for the video. Question: Is it possible to trigger the same aws lambda function from a rabbitmq instance that is running on EC2 (as oppossed to a managed rabbitmq instance) ?
Your audio is too low. Please setup the audio quality it is quite poor.
Quick update the load balancer policy is not working, I had to update the same to create the Load Balancer, otherwise the host address was coming as blank.
what did you change can you please tell
When I am applying deployment I am getting this error: error: error validating "deployment.yaml": error validating data: failed to download openapi: the server has asked for the client to provide credentials; if you choose to ignore these errors, turn validation off with --validate=false Any suggestions how to fix it ?
What if i am Using mysql db with RDS connection?
Nicely delivered the content with clear demonstration. Go ahead. Great Job. 👍
Can i use internal user database to login the dashboard?
HI, demn girl you explained it so well. I have a question, if we follow the exact pipeline and in the lambda function write a code to connect to ec2 instance and over that ec2 use the newly added file in s3 bucket input for a python code for some calculation. It should work fine right. For ex : - upload the file in s3 -> sns topic-> sqs que -> lambda -> ec2 (run and connect) -> runs the python file.(command given in lambda function). correct?
Thanks Great work!
Thanks!
A lot of videos doing this out there, but this one saved me! Most people skip something that we are stuck on, congrats.
Thank you :)
This really helped me out! Great quality, keep going :)
Thank you :)
Thanks, very well explained.
Thank you :)
Thank you for the tutorial. I am getting this error though: "errorMessage": "'NoneType' object has no attribute 'upper'", "errorType": "AttributeError", "stackTrace": [ " File \"/var/task/lambda_function.py\", line 95, in lambda_handler 'method': method.upper(), "
Hello, Looks like the event object is missing or getting passed as None. Please check your api gateway setup and try triggering a test event from api gateway.
Hi, this process works same even if we take more than one service right? Cause I have to deploy three microservices and routing takes places right ?
Hello, yeah, you should be able to extend this.
iam getting error like : error: the path "deployment.yaml" does not exist
Please cd into the folder where you have placed your deployment.yaml file in cmd before executing the commands.
Thanks :)
Good general overview of Cloudformation and step through of the generisation of the templates is well done. Demo of create Cloudformate template is also very clear.
Glad it was helpful! :)
Too fast
ah, sorry about that. Will make it a bit slower in the future videos. You could try switching to a slower speed setting in the youtube videos.
Easy to follow. But I find the token things at the end is quite confusing. Would be good if you could make another video to explain how the token works.
Thanks. Please let me know which part is confusing, I could try and explain here.
Getting Internal server error. In the lambda handler event is coming as empty checked in CloudWatch logs
Please try to check you api gateway setup and the version of opensearch
This is awesome tutorial. Very useful. Thanks!
Thank you :)

Hello, please try setting aws-region
audio too low
in the deployment yaml file how did get the image can u explain
the image is from aws public ecr repository
i have followed all the step still not able to create the alb
Very nicely explained, on how to set up ingress for our EKS cluster! Keep up the great work. May God bless you!
