Sometimes we might have to reboot EC2 instances. If the requirement is to restart EC2 instances regularly, we can achieve it by writing a small piece of code. I also came across a similar requirement and a portion of the code I used is given below.
| __author__ = 'Amal G Jose' | |
| import boto.ec2 | |
| class EC2Reboot(object): | |
| def __init__(self): | |
| self.instance_id_list = ["i-xxxxxx", "i-xxxxxx", "i-xxxxx", "i-xxxx", "i-xxxxx", "i-xxxxx", "i-xxxxx"] | |
| self.aws_access_key = "XXXXXXXXXXX" | |
| self.aws_secret_key = "XXXXXXXXXXX" | |
| self.region = "xx-xxxx-x" | |
| self.conn = boto.ec2.connect_to_region(self.region, | |
| aws_access_key_id=self.aws_access_key, | |
| aws_secret_access_key=self.aws_secret_key) | |
| def restart_instances(self): | |
| try: | |
| print "Rebooting instances: %s" %(str(self.instance_id_list)) | |
| self.conn.reboot_instances(self.instance_id_list) | |
| except Exception, e: | |
| print "Error occurred while restarting instances: %s" %(str(e)) | |
| if __name__ == '__main__': | |
| restart = EC2Reboot() | |
| restart.restart_instances() |
