ec2-scheduled-events is a small CLI tool by which you can get EC2 instance events (instance-reboot, system-reboot, system-maintenance, instance-retirement and instance-stop) by specifing AWS region information.
$ go get -u github.com/manamanmana/ec2-scheduled-events
As this CLI is using aws-sdk-go, you need to specify some credentials to access with AWS API.
You can set them as ~/.aws/credentials or environment variables like AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY.
You can see this in detail on https://github.com/aws/aws-sdk-go .
$ ec2-scheduled-events --region=<AWS region code>
Example:
$ ec2-scheduled-events --region=ap-northeast-1
CSV format with delimiter "\t".
<Instance ID>\t<Instance Name == Tag:Name>\t<Event Code>\t<Event Start Time>\t<Event End Time>\n
<Instance ID>\t<Instance Name == Tag:Name>\t<Event Code>\t<Event Start Time>\t<Event End Time>\n
...
Event Code == [instance-reboot|system-reboot|system-maintenance|instance-retirement|instance-stop]
