# Strip the top-level "override" and "default" attributes from Chef node JSON files.
|
|
#
|
|
# Usage:
|
|
# ./scripts/util/strip_node_attrs.sh <node> [<node> ...]
|
|
# ./scripts/util/strip_node_attrs.sh --all
|
|
#
|
|
# A <node> may be a bare node name (e.g. "prometheus-1"), a path relative to the
|
|
# repository root (e.g. "nodes/prometheus-1.json"), or an absolute path.
|
|
#
|
|
# Exit codes:
|
|
# 0 - all target files processed successfully
|
|
# 1 - one or more targets could not be processed (missing args, missing jq,
|
|
# file not found, invalid JSON, or write failure)
