Couple assumptions:
1. You've already installed the aws cli
2. You've already run aws configure
3. You are running this from an instance that never gets shutdown
Shutdown
#!/bin/bash
instance_list="instance1
instance2"
while IFS= read -r instance_id
do
status=$(aws ec2 describe-instances --instance-ids $instance_id | cut -f 3 | grep stopped)
echo "The instance $instance_id is $status"
while [ "$status" != 'stopped' ];
do
aws ec2 stop-instances --instance-ids $instance_id
sleep 10
status=$(aws ec2 describe-instances --instance-ids $instance_id | cut -f 3| grep stopped)
echo "The instance $instance_id is $status"
if [ "$status" == 'stopped' ]; then
echo "The $instance_id is $status"
break
fi
done
done <<< "$instance_list"
Startup
#!/bin/bash
instance_list="instance1
instance2"
while IFS= read -r instance_id
do
status=$(aws ec2 describe-instances --instance-ids $instance_id | cut -f 3 | grep running)
echo "The instance $instance_id is $status"
while [ "$status" != 'running' ];
do
aws ec2 start-instances --instance-ids $instance_id
sleep 10
status=$(aws ec2 describe-instances --instance-ids $instance_id | cut -f 3| grep running)
echo "The instance $instance_id is $status"
if [ "$status" == 'running' ]; then
echo "The $instance_id is $status"
break
fi
done
done <<< "$instance_list"
Right now this is doing it based on the list you write. I did out that if you could grab all instances like this:
instance_list=$(aws ec2 describe-instances | cut -f 8 | grep ^i-)
The problem is that your shutting down the box with the scripts. Plus I do have a couple of servers I don't want to go down. Good enough for now but I need to add a way to exclude instances and also save EIPs so I can reattach the same EIP when I bring it back up. If you know how to do it, please feel free to improve this in the comments!
