Signals Image Artist: Enabling connections from additional Harmony hosts

By default, SImA is configured with 5 EXTRA_HOST name definitions - see "Enabling Connections from Harmony" in the SImA Installation and Administration guide for further information. If additional EXTRA_HOST entries are required they should be defined via the docker-compose-custom.yml and .env files.

For example, to add 5 additional EXTRA_HOSTS entries in SImA version >= 1.2, add the following lines to the docker-compose-custom.yml file found in the SImA installation directory:x-celery-worker:

x-celery-worker: &celery-worker
  extra_hosts:
    - ${EXTRA_HOST6}
    - ${EXTRA_HOST7}
    - ${EXTRA_HOST8}
    - ${EXTRA_HOST9}
    - ${EXTRA_HOST10}

services:
  acapella:
    extra_hosts:
      - ${EXTRA_HOST6}
      - ${EXTRA_HOST7}
      - ${EXTRA_HOST8}
      - ${EXTRA_HOST9}
      - ${EXTRA_HOST10}

Note: If the docker-compose-custom.yml already contains any of the line entries listed above (e.g. the services: line), do not duplicate the entries. Omit the lines from the example above as required, so that the overall yaml structure is maintained. Please consult the Revvity Support team for clarification as required.

Next, add the below lines to the .env (also found in the SImA installation directory), then modify the hostname:IP values accordingly:

EXTRA_HOST6=placeholder6:192.0.2.6
EXTRA_HOST7=placeholder7:192.0.2.7
EXTRA_HOST8=placeholder8:192.0.2.8
EXTRA_HOST9=placeholder9:192.0.2.9
EXTRA_HOST10=placeholder10:192.0.2.10

The SImA stack would need to be redeployed for these changes to take effect.
