EdgeX Golang Services Monorepo | Owner: Core/Support WG

EdgeX Foundry Services

EdgeX Foundry is a vendor-neutral open source project hosted by The Linux Foundation building a common open framework for IoT edge computing. At the heart of the project is an interoperability framework hosted within a full hardware- and OS-agnostic reference software platform to enable an ecosystem of plug-and-play components that unifies the marketplace and accelerates the deployment of IoT solutions. This repository contains the Go implementation of EdgeX Foundry microservices. It also includes files for building the services, containerizing the services, and initializing (bootstrapping) the services.

Get Started

EdgeX provides docker images in our organization's DockerHub page. They can be launched easily with docker-compose.

The simplest way to get started is to fetch the latest docker-compose.yml and start the EdgeX containers:

wget https://raw.githubusercontent.com/edgexfoundry/developer-scripts/master/releases/edinburgh/compose-files/docker-compose-edinburgh-1.0.1.yml
docker-compose up -d

You can check the status of your running EdgeX services by going to http://localhost:8500/

Now that you have EdgeX up and running, you can follow our API Walkthrough to learn how the different services work together to connect IoT devices to cloud services.

Other installation and deployment options

Snap Package

EdgeX Foundry is also available as a snap package, for more details on the snap, including how to install it, please refer to EdgeX snap

Native binaries

Prerequisites

Go

The current targeted version of the Go language runtime is v1.11.5

pkg-config

go get github.com/rjeczalik/pkgconfig/cmd/pkg-config

ZeroMQ

Several EdgeX Foundry services depend on ZeroMQ for communications by default.

The easiest way to get and install ZeroMQ on Linux is to use this setup script.

For macOS, use brew:

brew install zeromq

For directions installing ZeroMQ on Windows, please see the Windows documentation.

pkg-config

The necessary file will need to be added to the PKG_CONFIG_PATH environment variable.

On Linux, add this line to your local profile:

export PKG_CONFIG_PATH=/usr/local/Cellar/zeromq/4.2.5/lib/pkgconfig/

For macOS, install the package with brew:

brew install pkg-config

Installation and Execution

EdgeX is organized as Go Modules; there is no requirement to set the GOPATH or GO111MODULE envrionment variables nor is there a requirement to root all the components under ~/go (or $GOPATH) and use the go get command. In other words,

git clone [e-mail]:edgexfoundry/edgex-go.git
cd edgex-go
make build

If you do want to root everthing under $GOPATH, you're free to use that pattern as well

GO111MODULE=on && export GO111MODULE
go get github.com/edgexfoundry/edgex-go
cd $GOPATH/src/github.com/edgexfoundry/edgex-go
make build

To start EdgeX

make run

or

cd bin
./edge-launch.sh

Note You must have a database (Mongo or Redis) running before the services will operate correctly. If you don't want to install a database locally, you can host one via Docker. You may also need to change the configuration.toml files for one or more of the services.

Build your own Docker Containers

In addition to running the services directly, Docker and Docker Compose can be used.

Prerequisites

See the install instructions to learn how to obtain and install Docker.

Installation and Execution

Follow the "Installation and Execution" steps above for obtaining and building the code, then

make docker run_docker

Note The default behavior is to use Mongo for the database, use the command make EDGEX_DB=redis run_docker to start EdgeX with Redis.
