Signing Service Not Available
I’m trying to setup a signing service to use with digital signatures. I’m receiving a
500 - Signing service not available error. My
SIGNING_SERVICE_URL is pointed at
http://localhost:6000/sign and I can confirm that the signing service is up and running. What should I do?
If you’re developing your own signing service or running our signing service reference implementation, you need to make sure that you can run the signing service as a sibling container to PSPDFKit Server in the same network.
The simplest way to have things working together is to use a specific directory structure and a unified
docker-compose.yml file, so that your application and the signing service sit side by side with the
. ├── docker-compose.yml ├── my-app └── signing-service
The Docker Compose file should have a structure with all 3 services:
services: pspdfkit: ... environment: SIGNING_SERVICE_URL: http://signing_service:6000/sign depends_on: - signing_service signing_service: build: ./signing-service ... my_app: build: ./my-app ... depends_on: - pspdfkit
Finally, when specifying the
SIGNING_SERVICE_URL in your PSPDFKit Server configuration, the URL host has to point to a location reachable by the PSPDFKit Server container.
For this reason, using a URL pointing to
localhost cannot work: the PSPDFKit Server container resolves
localhost to itself, not to the host machine running the signing service. Instead, the
SIGNING_SERVICE_URL should point at the
