- Detect <stack>/ folder vs flat <stack>.yaml automatically - Main file must be named <stack>.yml or <stack>.yaml inside folder - Extra *.yml/*.yaml files in folder merged via docker compose config - Env file resolved from folder/<stack>.env or flat <stack>.env - Flat path unchanged — zero regression for existing stacks - envsubst applied after compose config merge in folder mode"

# stack-deploy.sh — Safe Docker Swarm stack deployer
|
|
# Supports:
|
|
# - Flat: <stack>.yaml (legacy, all existing stacks)
|
|
# - Folder: <stack>/ (new, multi-compose stacks like immich)

|
|
# Folder layout:
|
|
# compose-files/
|
|
# └── immich/
|
|
# ├── immich.yml ← main compose (must match stack name)
|
|
# ├── hwaccel.transcoding.yml ← extension files, merged in glob order
|
|
# ├── hwaccel.ml.yml
|
|
# └── immich.env ← optional, same as flat pattern

# All files in the folder matching *.yml or *.yaml are included.

# Main file (<stack>.yml or <stack>.yaml) is always passed FIRST.
