Warning
The main branch of this repository contains work-in-progress development code for the upcoming release, and is not guaranteed to be stable or working. It is only compatible with the main branch of edgex-compose which uses the Docker images built from the main branch of this repo and other repos.The source for the latest release can be found at Releases.
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.
Currently, the NATS Messaging capability (NATS MessageBus) is opt-in at build time. This means that the published Docker images and Snaps do not include the NATS messaging capability.
The following make commands will build the local binaries or local Docker images with NATS messaging capability included for the Core and Support services.
make build-nats
make docker-natsThe locally built Docker images can then be used in place of the published Docker images in your compose file.
See Compose Builder nat-bus option to generate compose file for NATS and local dev images.
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:
release="main" # or "jakarta" for latest
wget https://raw.githubusercontent.com/edgexfoundry/edgex-compose/${release}/docker-compose.yml
docker-compose up -dYou 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.
Starting with the Fuji release, EdgeX includes enhanced security features that are enabled by default. There are a few major components that are responsible for security features:
- Security-secretstore-setup
- Security-proxy-setup
As part of Ireland release, the security-secrets-setup service is no more as internal service-to-service communication will not run in TLS by default in a single box.
When security features are enabled, additional steps are required to access the resources of EdgeX.
- The user needs to create an access token and associate every REST request with the access token.
- The exported external ports (such as 59880, 59881 etc.) will be inaccessible for security purposes. Instead, all REST requests need to go through the proxy. The proxy will redirect the request to the individual microservices on behalf of the user.
Sample steps to create an access token and use the token to access EdgeX resources can be found here: Security Components
The components in this repository are available as a snap package. For more details on the snap, including how to build and install it, please refer to the snap directory.
- The current targeted version of the Go language runtime for release artifacts is v1.18.x
- The minimum supported version of the Go language runtime is v1.18.x
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 git@github.com:edgexfoundry/edgex-go.git
cd edgex-go
make buildIf 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 buildRecommended deployment of EdgeX services is either Docker or Snap. See Getting Started with Docker or Getting Started with Snap for more details.
If you need to run and/or debug one of the services locally, simply stop the docker container running that service and run the service locally from command-line or from your debugger. All executables are located in the cmd/<service-name> folders. See Working in a Hybrid Environment for more details.
Note that this works best when running the service in non-secure mode. i.e. with environment variable
EDGEX_SECURITY_SECRET_STORE=false
In addition to running the services directly, Docker and Docker Compose can be used.
See the install instructions to learn how to obtain and install Docker.
Follow the "Installation and Execution" steps above for obtaining and building the code, then
make docker Currently for EdgeX core services except support services (support-notification and support-scheduler services), the delayed start feature from the dependency go-mod-bootstrap / go-mod-secrets modules are excluded in go builds by default.
If you want to include the delayed start feature in the builds for these services, please change the Makefile in this directory. In particular, change the following boolean flag from false to true before the whole docker builds.
INCLUDE_DELAYED_START_BUILD_CORE:="false"
For support services, the delayed start feature is included by default as the default behavior of them are not started right away in Snap. Similarly, you can change the default and exclude it by modifying the boolean flag from true to false in the Makefile:
INCLUDE_DELAYED_START_BUILD_SUPPORT:="true"
The Compose Builder tool has the dev option to generate and run EdgeX compose files using locally built images for above. See Compose Builder README for more details.
make run no-secty devNote that this run all the edgex-go services using the locally built images.

Please refer to the EdgeX Foundry versioning policy for information on how EdgeX services are released and how EdgeX services are compatible with one another. Specifically, device services (and the associated SDK), application services (and the associated app functions SDK), and client tools (like the EdgeX CLI and UI) can have independent minor releases, but these services must be compatible with the latest major release of EdgeX.
Please refer to the EdgeX Foundry LTS policy for information on support of EdgeX releases. The EdgeX community does not offer support on any non-LTS release outside of the latest release.
