AWS EC2 Spot Instance PHP Adds Tag When Creating Spot Request
I would like to be able to include the tag when creating a spot request via PHP. When instantiated on demand, you can instantiate and then use it to produce the following:
$ec2->create_tags($instance_id, array( array('Key' => 'Name', 'Value' => 'MyTestMachine'), ));
However, when issuing a dot claim, the instance does not start immediately, so you need to create a watcher tag to handle this ... if you cannot add the tag in the request phase. I haven't found any documentation to show how it would look or how it looks like, does it exist?

For future people looking for a solution without a listener:
You can also have your own instance after creating it by including the CLI tag request in the user data. This is executed in the EC2 instance as a script at boot for many of the default EC2 AMIs (which also have the CLI installed).
To do this (using a stock image):
- Create an IAM role with permission to create tags on EC2.
- Specify the role in your instance request.
In your object instance request data, include the CLI command to create tags (for Linux - you can also do the equivalent with powershell if you are using windows). You will see that there is a built-in command to get the Instance ID from EC2 Metadata Service:
aws ec2 create-tags --resources `wget -q -O - http://169.254.169.254/latest/meta-data/instance-id` --tags Key=somekey1,Value=somevalue1 Key=somekey2,Value=somevalue2
You may need to enode the user data above as base64 if you are using the CLI or SDK to make a slick request. The AWS Web Console can do this for you, otherwise you can transfer custom data like this:
user="$(cat /scripts/userdata.sh | base64 -w 0)" aws ec2 request-spot-instances \"UserData\": \"$user\",\"InstanceType\": \"m1.small\"}"
What is it!
