JarCastingUsage: nomad:deploy. Plugin is not bound to any lifecycle phase by default (rather it is expected to be used as a part of release process), but it could be bound as usual, using <execution> block
Nomad needs artifact to be downloaded from some repository, it could not be deployed right from the target folder. Therefore, artifact is expected to be deployed to the repository first, and project distributionManagement.downloadUrl have to be set. Plugin constructs download URL using distributionManagement.downloadUrl, groupId, artifactId, version and classifier from the project POM. For SNAPSHOT artifacts, it downloads and parses maven-metadata.xml to get the latest uploaded version
Task name and task group name will be set to artifactId. These Nomad environment variables will be used:
| Variable | Default value | Description |
|---|---|---|
| NOMAD_ADDR | http://127.0.0.1:4646 | URL of the HTTP API |
| NOMAD_REGION | Region | |
| NOMAD_NAMESPACE | default | Job namespace |
| NOMAD_CA_CERT | Path to TLS Authority certificate file | |
| NOMAD_CLIENT_CERT | Path to client certificate file | |
| NOMAD_CLIENT_KEY | Path to client key file | |
| NOMAD_TOKEN | ACL token |
Additionally, you can set these parameters in the configuration block:
| Variable | Default value | Description |
|---|---|---|
| addr | from NOMAD_ADDR | Overrides API address |
| options | Java options, passed to nomad java driver to start the job | |
| datacenters | dc1 | List of data centers, divided by comma |
| port | http | Label for the dynamic port allocation |
| env | <env><key1>value1</key1>...</env> passed as a set of environment variables |
|
| meta | <meta><key1>value1</key1>...</meta> passed as meta information |
