|
|
resource_types:
|
|
- name: nomad
|
|
type: registry-image
|
|
source:
|
|
repository: cioplenu/concourse-nomad-resource
|
|
tag: latest
|
|
|
|
resources:
|
|

|
|
name: test
|

|
|
* `name`: (required) name of the job
|
|
* `token`: Nomad ACL token
|
|
|
|
## Behavior
|
|
|
|
### `check`: Check for new [versions](https://www.nomadproject.io/api-docs/jobs#list-job-versions) of the job
|
|
|
|
Checks if there are new versions of the job. It uses the `nomad job history` command of the [nomad
|
|
CLI](https://www.nomadproject.io/docs/commands/job/history) and not all versions since the first
|
|
deployment might be available.
|
|
|
|
### `in`: noop
|
|
|
|
### `out`: Run a new version of the job
|
|
|
|
Deploys a new version of the job to the cluster using `nomad job run` by reading a HCL job file.
|
|
[Golang template variables](https://golang.org/pkg/text/template/) can be used to insert information
|
|
like a version on the fly.
|
|
|
|
#### Parameters
|
|
* `job_path`: (required) Path of the HCL job file to run
|
|
* `vars`: { [key: string]: string } dictionary of variables to substitute in the job file. Each key
|
|
should be represented in the job file as `{{.key}}`
|
|
* `var_files`: { [key: string]: string } dictionary of paths to files to read to get variable
|
|
values. Each key should be represented in the job file as `{{.key}}` and the values should be path
|
|
to text files which content will be used as the variable value. Whitespace and trailing newlines
|
|
will be trimmed from the value.
