This file 23 will be read and the job checked for any problems. If the 24 supplied path is "-", the job file is read from STDIN. Otherwise it is read 25 from the file at the supplied path or downloaded and read from URL specified. 26 Nomad downloads the job file using [`go-getter`](https://github.com/hashicorp/go-getter) 27 and supports `go-getter` syntax. 28 29 On successful validation, exit code 0 will be returned, otherwise an exit code 30 of 1 indicates an error. 31 32 ## Examples 33 34 Validate a job with invalid syntax: 35 36 ``` 37 $ nomad job validate example.nomad 38 Job validation errors: 39 1 error(s) occurred: 40 41 * group "cache" -> task "redis" -> config: 1 error(s) occurred: 42 43 * field "image" is required 44 ``` 45 46 Validate a job that has a configuration that causes warnings: 47 48 ``` 49 $ nomad job validate example.nomad 50 Job Warnings: 51 1 warning(s): 52 53 * Group "cache" has warnings: 1 error(s) occurred: 54 55 * Update max parallel count is greater than task group count (6 > 3).
