I am trying to use aws container service as per the documentation in http://docs.aws.amazon.com/AmazonECS/latest/developerguide/ECS_GetStarted.html
The below error is thrown when running the command:
aws ecs list-container-instances --cluster default
You must specify a region. You can also configure your region by running "aws configure".
The documentation does not mention anything about specifying a default region. How do we do it in a console?
I think you need to use for example:
aws ecs list-container-instances --cluster default --region us-east-1
This depends of your region of course.
"You must specify a region" is a not an ECS specific error, it can happen with any AWS API/CLI/SDK command.
For the CLI, either set the AWS_DEFAULT_REGION environment variable. e.g.
export AWS_DEFAULT_REGION=us-east-1
or set it in the CLI configuration file: ~/.aws/config
[default]
region=us-east-1
or pass/override it with the CLI call:
aws ecs list-container-instances --cluster default --region us-east-1
#1- Run this to configure the region once and for all:
aws configure set region us-east-1 --profile admin
Change admin next to the profile if it's different.
Change us-east-1 if your region is different.
#2- Run your command again:
aws ecs list-container-instances --cluster default
I posted too soon however the ways to configure are given in below link
http://docs.aws.amazon.com/cli/latest/userguide/cli-chap-getting-started.html
and way to get access keys are given in below link
