Hi, When you create a folder in Amazon S3, S3 creates a 0-byte object with a key that’s set to the folder name that you provided. If the object is deleted and there are no files using that path, then the folder will also disappear. In the article on my blog, or in a comment to this article, I provided a way to create the folder again. lepczynski.it/en/aws_en/automatically-delete-old-files-from-aws-s3/

You can find the code and additional explanations related to this topic in the article on my blog lepczynski.it/en/aws_en/how-to-read-and-write-a-file-on-s3-using-lambda-function-and-boto3/ I hope this will help you.

@@WojciechLepczynski Thanks for replying but code not seems working

@@aadityathakur972 Today I created a new lambda function, copied the function code from my blog and I must say that everything works fine. I don't get any error. I don't know why you get this error, it's possible that your code is different from the one I shared on the blog. In such a case, I can only advise you to check the code again or contact AWS support because everything works fine for me. Others also wrote in the comments that everything works, so I assume that you are doing something differently, not as I described. Have a nice day and I hope you will fix the error that occurred in your lambda function.

No problem. I see that a lot of people had the same problem as me, I'm glad it was useful.

There are no implicit or automatic permission to use or manage a KMS key. The primary way to manage access to your AWS KMS resources is with policies. KMS keys belong to the AWS account in which they were created. However, no identity or principal, including the AWS account root user, has permission to use or manage a KMS key unless that permission is explicitly provided in a key policy, IAM policy or grant. The IAM identity who creates a KMS key is not considered to be the key owner and they don't automatically have permission to use or manage the KMS key that they created. Like any other identity, the key creator needs to get permission through a key policy, IAM policy, or grant. However, identities who have the kms:CreateKey permission can set the initial key policy and give themselves permission to use or manage the key. To better understand KMS you can read for example docs.aws.amazon.com/kms/latest/developerguide/control-access.html

@@WojciechLepczynski thanks for your explanation, I was a bit confused with the key policy.

sure, no problem KMS, especially cross-account and cross-region can be confusing

Yes. If you do nothing, your files will still be in S3. You can create a lifecycle policy as I described in the video and your unused files will be automatically deleted after the time you specify. It could be 30 days, a year or several years. This will save you time and money. If you need to store files for a long time but you don't use them, it's a good idea to familiarize yourself with the different storage classes for example aws.amazon.com/s3/storage-classes/glacier/

@@WojciechLepczynski Thank you sir!

Sure, no problem, if you have a question related to the movie, don't hesitate and write a comment. By the way, there will be another movie soon. You can find more information related to clouds and devops on my blog lepczynski.it/en .

Thanks for the feedback, new video coming soon.

Hi, using versioning in S3 you can have several versions of the same file. So if you don't use versioning then you can only delete the current version like I did. If you want to remove all versions, you must also select remove noncurrent versions. You can find more about versioning in docs.aws.amazon.com/AmazonS3/latest/userguide/Versioning.html

Thanks for the feedback. I didn't add background music in every video. I'm currently wondering how to use it and whether to do it or not.

Lower the background music. It was a little bit too high, but great video. Thank you!@@WojciechLepczynski

Sure, in newer videos I set the background music level lower. Thanks for the feedback.

I think I wrote about it on my blog, If you move all files, the folder will be automatically deleted, but after moving the files you can create it again if you want. You can create a folder with put_object: client = boto3.client('s3') response = client.put_object(Bucket='test-745df33637-source-lambda-copy', Body='', Key='test-folder/')

Thanks for the feedback. There are several ways to deal with overlapping IP addresses, the simplest one is, of course, renumbering IP networks. Private link or Private NAT Gateway also comes to mind. If you are interested in using Private NAT Gateway, I discussed it in more detail in video th-cam.com/video/fIcKD8jASyQ/w-d-xo.html

Happy New Year 2024

Hi, you can run lambda functions every day using, for example, CloudWatch rule and check what files are older than 2 days and move them.

Hi, When you create a folder in Amazon S3, S3 creates a 0-byte object with a key that’s set to the folder name that you provided. If the object is deleted and there are no files using that path, then the folder will also disappear. You can add a filter to your Lifecycle rule, and "Specify minimum object size" and only delete objects > 0 bytes. I expect your 0-sized objects will remain, but I didn't test it. Once you check it, you can let me know if it works ;)

Thanks for the feedback, new video coming soon.

Calling the function depends on the S3 trigger, you only change the Prefix from 'images/' to 'images/subfolder1/' ( 3:30 in the video). Thanks to this, only when you add something to the subfolder 'subfolder1' in images, the function will be launched. You'll probably have to create a new trigger because AWS won't let you change the current one. Once you create a trigger, wait a few minutes and then test it

@@WojciechLepczynski got it. The thing is I'm uploading data from Kinesis to S3 on daily basis and each day it's creating me another subfolder. So in my case 'images' is really '2023' and then I have subfolder '11' and then under that '6' for yesterday, '7' for today, etc. So I'd like to copy files from one bucket to another one when for example tomorrow it will insert some files to newly created subfolder '8'. I mean I don't want to specify subfolder '8' as a source/trigger but I want it to work also for day after tomorrow, etc. Is it possible to achieve something like this with this function?

​ @arturpater9947 It is possible, If I understood correctly just specify the main folder, as '2023'. It should also work for all files and subfolders in it. For me, the trigger is the 'images' folder and if I create several subfolders in it and create a file, it will also call the function. You can also use 'CloudWatch events' as a trigger. You can specify that you move data from a folder and all subfolders to a different location every day at a specific time. It all depends on what you want to achieve. Of course, I recommend testing first. It may also turn out that you will need to improve the code in the lambda function.

Thanks for your support and kind words. I'm currently working on a video about warming up the lambda function.

Cool, that would be my next topic to learn in AWS. Thanks for always creating free stuff for us to learn. @@WojciechLepczynski

Thank you for your feedback. I usually speed up videos when I watch them. Someone already wrote about this. I don't want to waste your time, but I try to record each new video at a slower speed and add more content to it. The difficult balance is between giving short advice and adding enough background. Thanks again for the feedback, I hope it gets better with each video, if not please let me know.

I just provide the name of the S3 bucket and the place where I want to save the file. The file '001' didn't exist before. You can simply provide the file name, or the path if the file should be in a directory. You can find more details and code in the article on my blog: lepczynski.it/en/aws_en/how-to-read-and-write-a-file-on-s3-using-lambda-function-and-boto3/

Thanks for watching :) There can be a thousand reasons why you can't connect, from missing permissions to missing rules in the security group. Provide more details about what you did and what specific errors you get, and maybe then I can provide an answer with more details.

Sorry I don't know what you mean to do the same but without installing SSM agent. If you want, you can use other programs to read metrics and trigger an alarm, e.g. datadog, prometheus, zabbix, etc.

@@WojciechLepczynski I meant there is the information in AWS on the memory usage but I don't want to install anything additional to watch it. It sounds just ridiculous. Just imagine a browser where you have to install an additional software just to say, make a search on browsed pages.

@@KatherineMitrich ok now I understand what you meant. By default, you have access to a few basic metrics like CPU utilization, disk read operations, network packet and so on, but if you want more, you need to send such information from the machine. List the available CloudWatch metrics for your instances: docs.aws.amazon.com/AWSEC2/latest/UserGuide/viewing_metrics_with_cloudwatch.html You can send additional metrics to CloudWatch, for example, using the agent. The agent can be configured in various ways, you don't need to log in to ec2, you can use, for example, Systems Manager.

Thanks!@@WojciechLepczynski
