I am executing the following command
aws ec2 describe-instances
The error that i am getting is:
Could not connect to the endpoint URL: "https://ec2.us-west-2.amazonaws.com/"
I tried this link in my browser and it was working fine. Actually i am completely new to AWS cli and i am trying to stop, start my instances using AWS cli.
I have used the command aws configure and then provided my access key and secret key. In the region i have entered us-west-2 and output as json.

I have like 15 Lightsail instances created on my AWS account and now I wanted to know when these Lightsail instances were created.
The creation date of the Lightsail instances on which date and time these were created. But is not able to find this information from the AWS Lightsail console.
You can use the AWS Command Line Interface (AWS CLI) to retrieve the creation date of your Lightsail instances. The following AWS CLI command will list all of your Lightsail instances and the creation date for each instance:
aws lightsail get-instances --query "instances[*].{Name:name, CreationDate:createdAt}"
This command uses the get-instances command to retrieve information about all of your Lightsail instances, and the --query option to extract the name and creation date of each instance.
Alternatively, you can also retrieve the creation date of a specific Lightsail instance by using the get-instance command and specifying the instance name:
aws lightsail get-instance --instance-name <instance_name> --query "instance.createdAt"
Replace <instance_name> with the name of the Lightsail instance you want to retrieve information for.
Note: The AWS CLI must be installed and configured on your local machine in order to use these commands.
If you haven't already done so, just follow these steps:
1- Install the AWS CLI:
You can install the AWS CLI on your local machine by following the installation instructions for your operating system. You can find the installation instructions at the following URL: https://aws.amazon.com/cli/
2- Configure the AWS CLI:
After installing the AWS CLI, you need to configure it with your AWS credentials. You can do this by running the following command:
aws configure
This will prompt you for your AWS access key ID, secret access key, default region name, and default output format. You can find your AWS access keys in the AWS Management Console.
3- Verify the configuration:
To verify that your AWS CLI is configured correctly, you can run the following command:
aws lightsail get-instances
This command should list all of your Lightsail instances in your AWS account.
With the AWS CLI installed and configured, you can now use the AWS CLI commands to retrieve information about your Lightsail instances, including the creation date.
I hope my answer helps you
I am very new to AWS. I have a Windows Server EC2 instance. I installed AWS CLI on my laptop. Then I opened a CMD window, typed in "aws configure", put in the access key credentials, and was able to connect to the EC2.
From here, how do I get the http://169.254.169.254/latest/meta-data working? How do I retrieve some meta data?
On your Laptop
On your local machine you only can use the cli to retrieve metadata about your instance. Simply use this aws cli command:
aws ec2 describe-instance-attribute --instance-id <your-ec_instance_id e.g. i-ab12345> --attribute instanceType --region <your_region e.g. eu-west-1>
Documentation: http://docs.aws.amazon.com/cli/latest/reference/ec2/describe-instance-attribute.html
On your EC2-Instance only:
On your instance you can use the cli (like above) and the following:
PowerShell >3.0:
Invoke-RestMethod -uri http://169.254.169.254/latest/meta-data/instance-type
Documentation: http://docs.aws.amazon.com/AWSEC2/latest/WindowsGuide/ec2-instance-metadata.html
Or you can install "curl for windows" and run:
curl http://169.254.169.254/latest/meta-data/instance-type
When running on an EC2 instance, you can query the metadata service, like so:
curl http://169.254.169.254/latest/meta-data/public-ipv4
You can also use:
curl http://instance-data/latest/meta-data/public-ipv4
From outside the EC2 instance, you can use the awscli, like so:
aws ec2 describe-instances
--instance-ids i-01234567890123456
--query "Reservations[0].Instances[0].PublicIpAddress"
--output text
You cannot use http://169.254.169.254/latest/meta-data from AWS cli on your laptop
Use the ec2 describe-instances command instead for getting instance details
More details here
When I was trying to type "aws ec2 describe-instances" it will gives a blink cursor (AWS Command line). No results are showing.I have tried with setting the configurations for the user as well.
You have to provide instance details to get a description. like
aws ec2 describe-instances --instance-ids i-5xxxxbx
I am working through the examples and I simply can't listen the tables like in the given cli example.
My cli parameters
java -Djava.library.path=./DynamoDBLocal_lib -jar DynamoDBLocal.jar -inMemory
aws dynamodb list-tables --endpoint-url http://localhost:8000
Then it always asks me for a region and points me to "aws configure". When I entered nothing in the credentials and local as region I get:
Unable to locate credentials. You can configure credentials by running "aws configure".
What am I doing wrong? I just want to play around locally to get more familiar with the cli interface before I use the cloud itself. Bugs me a but that I cant get it work.
Thanks for any hints!
When running DynamoDB local, you don't need valid keys, but do put a valid region. For example, when running aws configure put any key for aws access key id, any key for aws secret access key and type us-east-1 or us-west-1 etc for regions.
Try running again the command, it should work.
I'm trying to use the AWS CLi for the first time, and I am doing it through putty by SSHing to the ec2 instance.
I want to run a command like "aws ec2 authorize-security-group-ingress [options]"
But I get the following error: "A client error (UnauthorizedOperation) occurred when calling the AuthorizeSecurityGroupIngress operation: You are not authorized to perform this operation."
I believe that this is related to IAM user credentials. I have found out where to create IAM users, however I still don't understand how this helps me to execute this command when I'm logged into the server as ec2-user or root, or run the command through CRON.
I have done a fair amount of reading regarding the access controls on AWS in their documentation, but I seem to be missing something.
How can I allow the command to be executed from within the AWS instance?
The missing information I was looking for is the command: aws configure
http://docs.aws.amazon.com/cli/latest/userguide/cli-chap-getting-started.html
$ aws configure
