Managed Security Groups
Ufo creates and manages two security groups. One for the ELB and one for the ECS tasks. Details here: UFO Security Groups.
You can disable the creation of managed security groups with:
managed_security_groups: false. Example:
base: image: tongueroo/demo-ufo managed_security_groups: false
Security Groups managed by UFO are transient. If you delete the UFO app and recreate it entirely. Any manual changes to the security groups will be lost.
You can precreate security groups and add them generated UFO CloudFormation template, see Settings Network. So then you won’t lose any manual changes. If you’re taking this approach, it’s nice to have UFO not create any managed security groups at all. This removes security group clutter.
