# `validate` Command
|
|
|
|
The `packer validate` Packer command is used to validate the syntax and
|
|
configuration of a [template](/docs/templates). The command will
|
|
return a zero exit status on success, and a non-zero exit status on failure.
|
|
Additionally, if a template doesn't validate, any error messages will be
|
|
outputted.
|
|
|
|
Example usage:
|
|
|
|
```shell-session
|
|
$ packer validate my-template.json
|
|
Template validation failed. Errors are shown below.
|
|
|
|
Errors validating build 'vmware'. 1 error(s) occurred:
|
|
|
|
* Either a path or inline script must be specified.
|
|
```
|
|
|
|
## Options
|
|
|
|
- `-syntax-only` - Only the syntax of the template is checked. The
|
|
configuration is not validated.
|
|
|
|
- `-except=foo,bar,baz` - Validates all the builds except those with the
|
|
comma-separated names. Build names by default are the names of their
|
|
builders, unless a specific `name` attribute is specified within the configuration.
|
|
|
|
- `-only=foo,bar,baz` - Only validate the builds with the given comma-separated
|
|
names. Build names by default are the names of their builders, unless a
|
|
specific `name` attribute is specified within the configuration.
|
|
|
|
- `-var` - Set a variable in your packer template. This option can be used
|
|
multiple times. This is useful for setting version numbers for your build.
|
|
|
|
- `-var-file` - Set template variables from a file.
