create with option --disable-rollback about simple_deploy HOT 8 OPEN

@munjeli

You can pass Abort-no to simple_deploy create.

simple_deploy create -e env -n stack_name -a Abort=no

Let us know if that solves your problem so we can close this.

Thanks.

Alas, that didn't work. My stack is rolling back on failure.

My bad. I forgot that we add abort support to our cloud formation templates to support that. When I am back at a laptop I can post a snippet for you if you want to try in your template.

@munjeli are you refering to the disable rollback option below:

DisableRollback
Set to true to disable rollback of the stack if stack creation failed. You can specify either DisableRollback or OnFailure, but not both.

Default: false

Type: Boolean

Required: No

Please do. For some reason I can't get it to work in the template even though I read the docs. A snippet would be helpful.

Here we go. The hope is you can use this so we don't have to add an option to simple_deploy.

Wow, no wonder I didn't figure it out :P

Thanks so much, I'll run these or mod my own. It shouldn't be you supporting the option, we should be able to access the option as a regular parameter in the template. It's a bit goofy to have it as a property of the stack but not being able to access it on the template.

Close the issue!

@brettweavnet-intuit yes, the option on the cli where I can create a stack with --disable-rollback. Tragically, there isn't a way to insert "DisableRollback": True into the template.
