I see fiware/iotagent-ul-ngsi-ld is missing from docker hub. Is this published with some other name on it. Please suggest, as its holding our project work.

If you cannot find the image in docker hub you can always built in locally. Have a look to "How to build an image" "Building from your own source files" in https://github.com/telefonicaid/iotagent-ul/tree/master/docker documentation.

Note that before running docker build you have to need to modify package.json to change iotagent-nod-lib depencency to:

     "iotagent-node-lib": "git://github.com/telefonicaid/iotagent-node-lib.git#feature/842_ngsi_ld",

Hello Jason,

Many thanks for your response. I tried building it and getting below error:

chmod: cannot access 'docker/entrypoint.sh': No such file or directory

I tried to find this file on github path and other locations but could not find.

Please suggest.

Thanks & Regards,
Sunil Kumar

@vistasunil - you can find some sample dockerfiles here: https://github.com/FIWARE/tutorials.IoT-Agent/tree/NGSI-LD

Hello @jason-fox Jason,

None of the Dockerfile helped as these seems to be compatible for Non-LD Iot-agents. Do I need to do some configuration changes to use this for LD Iot-agent.?

Thanks & Regards,
Sunil Kumar

@vistasunil - of course config changes are needed to support NGSI-LD - if you follow the existing tutorial on the NGSI-LD branch it will work as the tutorial uses the docker-compose files found here

The main alteration is the additional ENV attributes found here:

  environment:
      - IOTA_CB_NGSI_VERSION=ld # use NGSI-LD when sending updates for active attributes
      - IOTA_JSON_LD_CONTEXT=http://context:3000/data-models/ngsi-context.jsonld
      - IOTA_FALLBACK_TENANT=openiot

All this has already been fully documented in this PR: https://github.com/telefonicaid/iotagent-node-lib/blob/feature/842_ngsi_ld/doc/installationguide.md - I'm still waiting for progress in merging it.

Do you mean you get that error when following "Building from your own source files" in https://github.com/telefonicaid/iotagent-ul/tree/master/docker documentation? Could you detail which exact steps did you do, please?

It would be great to know, as it could point to some error on the procedure described in documentation (independly of using NGSI-LD or not).
