you can use the following command - sudo dnf install postgresql15.x86_64 postgresql15-server -y

What is the error that you are getting ??

thanks

Yes I do

@@AWSTrainingByGauravAgrawal how can i reach you sir

@@akshaykatkam2340 u can WhatsApp me on 9834385881

Great!

I used OBS studio for recording the vidoe and powerpoint for the ppt.

Glad it was helpful!

Yes

@@AWSTrainingByGauravAgrawal I got the payment mail do u have any vdo tht how to pay that?

@@tanayaraut549 no I don’t have a video for that. But the email should have the steps on how to proceed.

I guess by terminate you mean delete, right ? No please dont delete the default vpc, as the name says. - it is "default" and it is required for creating your EC2 instances. In case you have deleted the default vpc, then go to the "Your VPCs" section on left side, then "Actions" -> "Create default VPC"

Please refer to this video - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-XGkm2BwNpyI.html For your requireement, the flow will be - EC2 Service -> listen to EC2 create instance events in Eventbridge --> Trigger lambda --> Send email to an group or whoever you want.

Didn’t u got an email while setting up the email in SES ? Check your spam Folder also

No I don't got I hav also check spam 😕​@@AWSTrainingByGauravAgrawal

Please go through the video again then, mostly all of the associates have received the email.

Yes vry helpful

@@AWSTrainingByGauravAgrawal do u have any vdo of how to create an S3 bucket??

No you cannot do it without a compute instance. you need a way to run some code which will trigger the shutdown command to the correct set of instances and thats where lambda's come in. They are on demand and you only pay for the time it is running, so it actually very cost effective.

we can do it with Azure DevOps pipeline completely free

yeah, you can do it without using a lambda... no compute, just use event bridge for EC2 stop (not lambda), obviously you need IAM Role for your Scheduler (trusted policy for scheduler and IAM policy for actions on ec2) .... and you have a EC2 scheduler without lambda now guy :)

Glad it helped!

Any idea how I can see the logs? When I go to cloudwatch logs I get error saying the log group does not exist

You cannot bypass email subscription in local and for production setup, subscription is not required

@@AWSTrainingByGauravAgrawal Thank you Gaurav

@@AWSTrainingByGauravAgrawal Hi Gaurav.. Though I am using the aws dev account of my organisation, it is still asking for verification

Same password

If you know the list of ec2 instance id's then you can run the following aws command - aws ec2 start-instances --instance-ids i-INSTANCE_ID1 i-INSTANCE_ID2 i-INSTANCE_ID3

@@AWSTrainingByGauravAgrawal ​Sure I can use that, however, I would like a script like you mentioned Python script, for example, to shut down the instance and I would use multiple instance IDs to auto-start the instance. Is it possible to get a complete Python script to auto-start the instance? it will be very helpful for me

@@that_epics use the below python lambda code import boto3 def lambda_handler(event, context): # Create a Boto3 EC2 client ec2 = boto3.client('ec2') # Describe all instances in your account instances = ec2.describe_instances() # Extract instance IDs from the response instance_ids = [] for reservation in instances['Reservations']: for instance in reservation['Instances']: instance_ids.append(instance['InstanceId']) # Start all instances if instance_ids: ec2.start_instances(InstanceIds=instance_ids) return f'Starting instances: {instance_ids}' else: return 'No instances to start' # Note: Make sure that your Lambda function has the appropriate IAM permissions to describe and start EC2 instances.

​@@AWSTrainingByGauravAgrawalSorry I am bothering you but where is the name of the tag like start=true and where I can mention only two or three examples of the ID is only.

Earlier script you mentioned tags to stop each instance

Glad you enjoyed it

ECR is in free tier till 500MB for the first year of your AWS account

Sorry, I didnt got your quesion

Yes I do

Amazon S3 does not provide a built-in feature to automatically move an object back to its previous storage class. However you can manually edit the object and changed the storage class to the desired class. Also the lifecycle transitions happens from higher cost storage class to the lower cost storage class and not vice versa

The data will be stored on the local EBS volume which is attached to the EC2 instance.

@@AWSTrainingByGauravAgrawal so there will no problem with that . Storing the data on Ebs.Thanku sir for replying

No problem with that. The RDS service also stores data on the EFS volume. Volume is the only way to store data. All the other services like EFS, S3 also store their data on EB S volumes.@@crazy_gamers_0079

Thanks Sahab. I have keep the lambda code simple to reduce the complexity. The lambda code as of now is deleting any instance that got created. We can modify this code to ignore certain instance types. Let me know if you are looking for a modified lambda. I can provide you the same.

I'm waiting for your response for above queries.

go thru the other videos also and perform hands on of the same.

thanks for the feedback 🙂
