OS2IoT-docker

This repository contains the docker-compose file and configuration needed to run the OS2IoT project.

Documentation is available at: https://os2iot.readthedocs.io/en/latest/

Usage

Currently (for development) we mount the source-code into the front-end and back-end containers, so it's required that you clone them into the same parent directory as this project:

OS2IoT
├── OS2IoT-backend (https://github.com/OS2iot/OS2IoT-backend)
├── OS2IoT-docker (https://github.com/OS2iot/OS2IoT-docker)
├── OS2IoT-frontend (https://github.com/OS2iot/OS2IoT-frontend)

From the OS2IoT-docker folder in a suitable terminal use:

docker-compose up

Configuration

Edit the files in the configuration folder to adjust settings for each requirement.

Contents

  • Postgres from the official image.
  • Chirpstack using their docker-compose

Troubleshooting FAQ

Docker File Sharing issues

ERROR: Encountered errors while bringing up the project.

Cause: Docker doesn't have acceess to mount the volumes.

Solution: On Windows: Go to Docker Desktop (tray icon) -> Settings -> Resources -> File Sharing -> Add the directory which is the parent directory of "OS2IoT-docker" or a parent of that. -> Apply & Restart

error: database "os2iot-e2e" does not exist

[ExceptionHandler] Unable
to connect to the database. Retrying (1)...
error: database "os2iot-e2e" does not exist
    at Parser.parseErrorMessage

Cause: Database has not been setup correctly on local machine.

Solution: docker-compose down --volumes dos2unix configuration/os2iot-postgresql/initdb/* <-- Skal køres fra git bash docker-compose up

error: Error: connect ETIMEDOUT xxx.xxx.xxx.xxx:xxxx at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1141:16)

Cause: Docker is trying to connect to the wrong ip.

Solution:

  1. Navigate to hosts file: C:\Windows\System32\drivers\etc
  2. Open hosts file as administrator
  3. Change related ip of host.docker.internal and gateway.docker.internal to your new ip (found in terminal using the ipconfig command: e.g. 192.168.0.1)
  4. save
  5. restart the application.

Adding an ADR Algorithm

When the ADR Algorithm has been tested, and is ready for deployment, the ADR Algorithm has to be added to chirpstack. It is mandatory that the custom adr module is writtin in js.

Adding the Plugin to Chirpstack

Docker

If the default docker-compose.yml file is used, the folder ./configuration/chirpstack is already copied to /etc/chirpstack in the docker container. Therefore a new folder can be added such as ./configuration/chirpstack/adr-modules in which the js file can be added. This makes the file available at /etc/chirpstack/adr-modules/example-file.js within the chirpstack container.

The last step is to specify the file as being an adr-plugin within the chirpstack.toml config file by adding adr_plugins=["/etc/chirpstack/adr-modules/example-file.js"] under [network], like this:

[network]
    adr_plugins=["/etc/chirpstack/adr-modules/example-file.js"]

You should now be able to restart the chirpstack server and the new adr algorithm should be available in Chirpstack.

Helm

When hosting via helm the steps are slightly different.

  1. Make sure that the persistent volume claim belonging to the chirpstack exists in your hosted setup.
  2. Find the actual name of the network-server pod. This can be done in a few ways. If you're have a connection via a GUI like Lens it can be found under the Pods list. If you're hosting on an Azure Kubernetes service, it can be found under the side menu Workloads -> Pods
  3. Use kubectl to copy the module into the pod 
    kubectl cp ./path/to/module/adr-module chirpstack-xxxxxxxxx-xxxxx:/etc/chirpstack/adr-modules
  4. Update configmap.yaml located under /helm/charts/chirpstack/templates with the path to the plugin under [network], like this: 
    [network]
    adr_plugins=["/etc/chirpstack/adr-modules/example-file.js"]
    The first line already exists
  5. Once the helm chart has redeployed restart the network server to enable the new module.
