The current test script for e2e uses AWS SAM; I would like to make it CloudFormation etc. so that it can be used in environments where AWS SAM is not installed.

https://github.com/go-to-k/delstack/blob/main/testdata/deploy.sh#L207-L219

Describe the solution you'd like
Use CloudFormation, etc.

It is useful to allow selecting deletion resources as this I think.
ex. -i, --interactive

This occurred in the master branch, not now release version 0.5.0.

Cannot delete entity, must remove users from group first. (Service: AmazonIdentityManagement; Status Code: 409; Error Code: DeleteConflict; Request ID: xxxxxxxxxxxxxxxxxx; Proxy: null)

Describe the solution you'd like
Support AWS::IAM::Group resource type for force deletion. this removes users from the group and delete the group only.

It's a pain to launch the tool every time I want to delete multiple stacks.

Use fuzzy search libraries for searching stack names in the interactive mode.

Is your feature request related to a problem? Please describe.
When deleting multiple stacks, if the stack executed in the middle has TerminationProtection, it will terminate with an error on that stack after the previous stack is deleted. Better to know it first and not start deleting all the stacks.

Describe the solution you'd like
Check all stacks for TerminationProtection before starting deletion when multiple stacks.

Convert stackName and keyword to strings.ToLower, etc. before filtering with strings.Contains.

Right now it's a fixed time, so make it random and spread out.

About the problem

The interactive mode of the delstack command displays a list of stack names. Below is an example:

? Select StackName.
Nested child stacks, XXX_IN_PROGRESS(e.g. ROLLBACK_IN_PROGRESS) status stacks and EnableTerminationProtection stacks are not displayed.
  [Use arrows to move, type to filter]
  stack-a
  stack-b
  stack-c
> stack-d

User select one stack from the above list.
When the user is choosing a stack name, pressing the [Enter] key is expected. However, if the user accidentally presses the [Space] key, the delstack display no stack name. Below is an example:

? Select StackName.
Nested child stacks, XXX_IN_PROGRESS(e.g. ROLLBACK_IN_PROGRESS) status stacks and EnableTerminationProtection stacks are not displayed.
    [Use arrows to move, type to filter]

Current workaround

If the user accidentally presses the [Space] key, pressing the [BackSpace] key will restore the display.

Expected behavior

When a user presses an irrelevant key, the screen should indicate that the user pressed the wrong key or be unresponsive. At the very least, I want the stack name to continue to be displayed on the screen.

Environment information

• macOS 13.6.3 (arm64)
• iTerm2 (Build 3.4.22)
• delstack version v1.4.1

Can I use this tool in my Github Workflow YML file? How to?

Originally not displayed in interactive mode, it still does not generate an error when the stack name is directly specified.

Need to detach from the Security Group and delete the ENI if Available status.

Additional context

Even if the case was DELETE_FAILED in the past, if it was for a temporary reason, it may succeed if you delete it again.

If skip the stack in that case, it will fail no matter how many times you run the tool.

Do not display stacks with delete protection in the interactive mode.

The type of []types.Stack for Stacks in DescribeStacksOutput, has the EnableTerminationProtection.

The type of []types.StackSummary for StackSummaries in ListStacksOutput(or the type of []types.Stack for Stacks in DescribeStacksOutput) has RootId and ParentId, so we can use for this feature.

If use DescribeStacks in the issue(#74), use DescribeStacks in this issue.

I think there is probably no situation where a child stack would be selected for deletion.

But is there really no such case? (e.g., when manually deleting the parent stack with the specified child stack as a skip resource).

If there is, do I need to consider it if it is infrequent...?

Now, once you delete a root stack and occurs DELETE_FAILED, this tool delete a root stack without DELETE_FAILED resources at first, then delete the rest resources.
However, if a part of DELETE_FAILED resources occurs errors, other resources are left and this tool exit. But the stack had been deleted, so it may be impossible to find the resources left behind.

Deleting a stack created by a script in testdata "rarely" causes the BucketNotEmpty error for DeleteBucket.

If I retry, sometimes succeed, sometimes fail again.

version: v0.9.0

ERR operation error S3: DeleteBucket, https response error StatusCode: 409, RequestID: JV10XTTNRKPGSZNM, HostID: 9HFEwhU0nHSbNxlWuxD3isgnKdbqi2VGKMHKahGUu+ZsGF21jgAaKnVhU++iQfdRczhushHebiA=, api error BucketNotEmpty: The bucket you tried to delete is not empty. You must delete all versions in the bucket.
exit status 1

It is not good psychologically for the user to get a lot of non-critical retry logs.

Throttling errors may occur with APIs such as GetRole that are not currently retried.

It could also be applied to ListAttachedRolePolicies.
