# Command: job validate
|
|
**Alias: `nomad validate`**
|
|
|
|
The `job validate` command is used to check a [HCL job specification](/docs/job-specification/index.html)
|
|
for any syntax errors or validation problems.
|
|
|
|
## Usage
|
|
|
|
```
|
|
nomad job validate <file>
|
|
```
|
|
|
|
The `job validate` command requires a single argument, specifying the path to a file
|
|
containing a [HCL job specification](/docs/job-specification/index.html). This file
|
|
will be read and the job checked for any problems. If the
|
|
supplied path is "-", the job file is read from STDIN. Otherwise it is read
|
|
from the file at the supplied path or downloaded and read from URL specified.
|
|
Nomad downloads the job file using [`go-getter`](https://github.com/hashicorp/go-getter)
|
|
and supports `go-getter` syntax.
|
|
|
|
On successful validation, exit code 0 will be returned, otherwise an exit code
|
|
of 1 indicates an error.
|
|
|
|
## Examples
|
|
|
|
Validate a job with invalid syntax:
|
|
|
|
```
|
|
$ nomad job validate example.nomad
|
|
Job validation errors:
|
|
1 error(s) occurred:
|
|
|
|
* group "cache" -> task "redis" -> config: 1 error(s) occurred:
|
|
|
|
* field "image" is required
|
|
```
|
|
|
|
Validate a job that has a configuration that causes warnings:
|
|
|
|
```
|
|
$ nomad job validate example.nomad
|
|
Job Warnings:
|
|
1 warning(s):
|
|
|
|
* Group "cache" has warnings: 1 error(s) occurred:
|
|
|
|
* Update max parallel count is greater than task group count (6 > 3). A destructive change would result in the simultaneous replacement of all allocations.
|
|
|
|
Job validation successful
|
|
```
