Usage: packer fmt [options] [TEMPLATE]
|
|
|
|
Rewrites all Packer configuration files to a canonical format. Both
|
|
configuration files (.pkr.hcl) and variable files (.pkrvars) are updated.
|
|
JSON files (.json) are not modified.
|
|
|
|
If TEMPATE is "." the current directory will be used. The given content must
|
|
be in Packer's HCL2 configuration language; JSON is not supported.
|
|
|
|
Options:
|
|
-check Check if the input is formatted. Exit status will be 0 if all
|
|
input is properly formatted and non-zero otherwise.
|
|
|
|
-diff Display diffs of formatting change
|
|
|
|
-write=false Don't write to source files
|
|
(always disabled if using -check)
