I need some help here. I’ve copied the tutorial and started tinkering with changes to make a PoC. I’m running into a wall running atmos terraform plan tfstate-backend --stack=uw2-root and can’t figure out what knob I turned to end up with stack name pattern must be provided in 'stacks.name_pattern' config or 'ATMOS_STACKS_NAME_PATTERN' ENV variable

Directory structure looks correct (at least I think)

somewhere in these locations

# CLI config is loaded from the following locations (from lowest to highest priority):
# system dir (`/usr/local/etc/atmos` on Linux, `%LOCALAPPDATA%/atmos` on Windows)
# home dir (~/.atmos)
# current directory
# ENV vars
# Command-line arguments

this is a working example https://github.com/cloudposse/atmos/tree/master/examples/complete that shows how to use atmos, plus all the stacks and components folders

note when you set the ENV var ATMOS_LOGS_VERBOSE=true, the CLI will print a lof more info - how it looks for the config, what config is found and processed, more info for the executing commands, etc.

Running into the following despite the backend plan and apply successfully completing.

⨠ atmos terraform backend generate component tfstate-backend --stack uw2-root
Invalid or missing configuration for the component 'generate' in the stack 'uw2-root'

if you are using atmos version > 1.0, the command is

atmos terraform generate backend <component> -s <stack>

also, the latest release will generate backend on the fly https://github.com/cloudposse/atmos/pull/66
