The "EC2: Create AMI" action allows you to create an Amazon Machine Image (hereinafter "AMI") from an Amazon EC2 instance (hereinafter "EC2 instance").
The AMI contains a disk image of the EC2 instance and information required to launch it, so that it can be used as a backup of your EC2 instance. As with other actions, you can specify the EC2 instance, from which the AMI is created, with a 、resource ID or a tag attached to the EC2 instance.

Configuration options

No	Option	Explanation
1	Region	Specify the region where the EC2 instance, which you want to retrieve an AMI, is located
2	Instance	Specify the EC2 instance, which you want to retrive the AMI, by resource ID
2	Instance with specified tag	Specify the EC2 instance, which you want to retrive the AMI, by tag
3	AMI name	Specify AMI name The resource ID, job ID and generation number of the created EC2 instance are attached to the end of the specified name
4	Explanation	Enter the text to be attached to the "description" of the created AMI You can include following keywords for the explanation %Y 4 digits Year (Example:2017) %m Month（01〜12） %d Day（01〜31） %H Time（00〜23） %M Minutes（00〜59） %S Second（00〜60） %% 「%」When escaping characters When you sepecify "%Y%m%d%H%M", it will be replaced with "201709231100". If you use a keyword in the description, the time zone of the time stored in the retrieved AMI description will be UTC.
5	Number of generations to be created	Select the number of generations for generation management of the created AMI For example, when there are already 5 AMIs created by Cloud Automator and the "generations to be created" option is 5, and the "EC2: Create AMI" action is further executed, the oldest AMI will be deleted to create new AMI. Example: production-backup-i-XXXXXXXXXXX-1234-1 When "No generation management" is selected AMI will not be deleted AMI name will be different from when generation management is enabled Example: prodbackup-i-1234567890abcdef1-12123-20190820T035938Z
6	Instance restart	Choose to restart your EC2 instance to provide a quiesce point when you get an AMI If data inconsistency is not allowed and restart downtime is acceptable, we recommend to restart
7	Tags to be added to the created image	Specify the tag key and tag value of the tag to be attached to the created AMI Add the same tag to the snapshot Select to attach the same tag key and tag value to the EBS snapshot linked to the AMI
8	Check the completion status of the resource	When not checking the completion status of a resource CreateImage API The success or failure of CreateImage API request is the result of job execution When checking the completion status of a resource A job is considered successful when the Create Image API request is successful and the status of the created AMI is available. When the Create Image API request is successful and the status of the created AMI is something other than available (such as failed), the job is determined to have failed.
9	Re-create an image when AMI status is "Failed"	Select to re-create if the AMI status is failed when checking the completion status of the resource

Setting post-process when succeeded or failed
Enter Job name and click "Confirm"

Operation check

Click log button for created Job
Click the details of the execution log from the execution log list
