Summary

An implementation of the WebPA API which enables communication with TR-181 data model devices connected to the XMiDT cloud as well as subscription capabilities to device events.

Table of Contents

Code of Conduct

This project and everyone participating in it are governed by the XMiDT Code Of Conduct. By participating, you agree to this Code.

Details

The WebPA API operations can be divided into the following categories:

Device Statistics - /stat endpoint

Fetch the statistics (i.e. uptime) for a given device connected to the XMiDT cluster. This endpoint is a simple shadow of its counterpart on the XMiDT API. That is, Tr1d1um simply passes through the incoming request to XMiDT as it comes and returns whatever response XMiDT provided.

CRUD operations - /config endpoints

Tr1d1um validates the incoming request, injects it into the payload of a SimpleRequestResponse WRP message and sends it to XMiDT. It is worth mentioning that Tr1d1um encodes the outgoing WRP message in msgpack as it is the encoding XMiDT ultimately uses to communicate with devices.

Event listener registration - /hook(s) endpoints

Devices connected to the XMiDT Cluster generate events (i.e. going offline). The webhooks library used by Tr1d1um leverages AWS SNS to publish these events. These endpoints then allow API users to both setup listeners of desired events and fetch the current list of configured listeners in the system.

Build

Source

In order to build from source, you need a working 1.x Go environment. Find more information on the Go website.

Then, clone the repository and build using make:

git clone [email protected]:xmidt-org/tr1d1um.git
cd tr1d1um
make build

Makefile

The Makefile has the following options you may find helpful:

  • make build: builds the Tr1d1um binary in the tr1d1um/src/tr1d1um folder
  • make docker: fetches all dependencies from source and builds a Tr1d1um docker image
  • make test: runs unit tests with coverage for Tr1d1um
  • make clean: deletes previously-built binaries and object files

RPM

First have a local clone of the source and go into the root directory of the repository. Then use rpkg to build the rpm:

rpkg srpm --spec <repo location>/<spec file location in repo>
rpkg -C <repo location>/.config/rpkg.conf sources --outdir <repo location>'

Docker

The docker image can be built either with the Makefile or by running a docker command. Either option requires first getting the source code.

See Makefile on specifics of how to build the image that way.

If you'd like to build it without make, follow these instructions based on your use case:

  • Local testing
docker build -t tr1d1um:local -f Dockerfile.local .  
# OR build for am arm64 architecture
bash
docker build -t tr1d1um:local --build-arg arm64=true -f Dockerfile.local .

This allows you to test local changes to a dependency. For example, you can build a tr1d1um image with the changes to an upcoming changes to webpa-common by using the replace directive in your go.mod file like so:

replace github.com/xmidt-org/webpa-common v1.10.2 => ../webpa-common

Note: if you omit go mod vendor, your build will fail as the path ../webpa-common does not exist on the builder container.

  • Building a specific version
git checkout v0.5.1
docker build -t tr1d1um:v0.5.1 -f Dockerfile.local .

Additional Info: If you'd like to stand up a XMiDT docker-compose cluster, read this.

Deploy

If you'd like to stand up Tr1d1um and the XMiDT cluster on Docker for local testing, refer to the deploy README.

You can also run the standalone tr1d1um binary with the default tr1d1um.yaml config file:

./tr1d1um

Kubernetes

A helm chart can be used to deploy tr1d1um to kubernetes

helm install xmidt-tr1d1um deploy/helm/tr1d1um
