A tool to generate AWS CLI command to continue-update-rollback a stack that is stuck in UPDATE_ROLLBACK_FAILED state. The resources to skip are essentially identified using a set of DescribeStackResources, DescribeStacks and DescribeStackEvents API Calls.
Works for stacks with nested stacks. Always pass the root stack ARN and the root stack must be in UPDATE_ROLLBACK_FAILED state. If your root stack is in a different state [ i.e, the nested stack was updated directly ], the stack is ideally in a stuck situation and would need AWS intervention to recover.
Required parameters -
--stack_arn or -s - The full arn of the root stack that is stuck in UPDATE_ROLLBACK_FAILED state
Installation -
git clone https://github.com/mrlikl/continue-update-rollback.git
cd continue-update-rollback
pip3 install -r requirements.txt
pip3 install -e .
Usage -
cfn-cur -s <stack-full-arn>
or
cfn-cur --stack_arn <stack-full-arn>
