Usage: packer validate [options] TEMPLATE
|
|
|
|
Checks the template is valid by parsing the template and also
|
|
checking the configuration with the various builders, provisioners, etc.
|
|
|
|
If it is not valid, the errors will be shown and the command will exit
|
|
with a non-zero exit status. If it is valid, it will exit with a zero
|
|
exit status.
|
|
|
|
Options:
|
|
|
|
-syntax-only Only check syntax. Do not verify config of the template.
|
|
-except=foo,bar,baz Validate all builds other than these.
|
|
-only=foo,bar,baz Validate only these builds.
|
|
-var 'key=value' Variable for templates, can be used multiple times.
|
|
-var-file=path JSON or HCL2 file containing user variables. [ Note that even in HCL mode this expects file to contain JSON, a fix is comming soon ]
