Service Keys¶

The following keys configure the PLOSSYS Distribution Engine services seal-dpf-workingunit-print-ipp and seal-dpf-workingunit-webportal, refer to Services. The services read their keys as environment variables. In a standard installation, each service loads them at startup from the env section of its configuration file:

Windows: C:\ProgramData\SEAL Systems\config\<service>.yml
Linux: /opt/seal/etc/<service>.yml

Hint - service keys are not job parameters

Unlike DPF job parameters, service keys are not normalized. Write each key exactly as listed on this page.

Hint - general service keys

The services also read general DPF service keys, for example LOG_LEVEL, SERVICE_URL, and SERVICE_PORT. They are described in the DPF documentation. Set them in the same configuration file.

MAX_INSTANCES¶

MAX_INSTANCES specifies the maximum number of jobs that the service processes in parallel.

The key is available for the following services:

seal-dpf-workingunit-print-ipp
seal-dpf-workingunit-webportal

Available values: Integer

Default: 3

Hint - preset of the configuration files

The configuration files installed with the seal-dpf-workingunit-print-ipp and seal-dpf-workingunit-webportal services set the key to 10.

RESTWU_URL_ORIGIN¶

RESTWU_URL_ORIGIN specifies the origin of the DPF REST WU Manager that the service connects to, refer to Ports.

The key is available for the following services:

seal-dpf-workingunit-print-ipp
seal-dpf-workingunit-webportal

Available values: String

<protocol>://<host>:<port>

Default: https://localhost:9126

REST_WU_MANAGER_URL¶

REST_WU_MANAGER_URL is deprecated. Use RESTWU_URL_ORIGIN instead.

The key is available for the seal-dpf-workingunit-print-ipp service.

Available values: String

<protocol>://<host>:<port>

Caution - remove the deprecated key

If REST_WU_MANAGER_URL is set, the service uses its value and logs a deprecation warning. In this case, the service ignores RESTWU_URL_ORIGIN.

When you switch to RESTWU_URL_ORIGIN, remove REST_WU_MANAGER_URL from seal-dpf-workingunit-print-ipp.yml. Otherwise, the service keeps using the old value.
