Release Artifacts




During the Geneva release of EdgeX Foundry the DevOps WG transformed the CI/CD process with new Jenkins pipeline functionality. After this new functionality was added we also started adding release automation. This new automation is outlined in ADR 0007 Release Automation. However, in ADR 0007 Release Automation only two release artifact types are outlined. This document is meant to be a living document to try to outlines all currently supported artifacts associated with an EdgeX Foundry release, and should be updated if/when this list changes.

Release Artifact Types

Docker Images

Tied to Code Release? Yes

Docker images are released for every named release of EdgeX Foundry. During development the community releases images to the docker.staging repository in Nexus. At the time of release we promote the last tested image from docker.staging to docker.release. In addition to that we will publish the docker image on DockerHub.

Nexus Retention Policy


Retention Policy: 90 days since last download

Contains: Docker images that are not expected to be released. This contains images to optimize the builds in the CI infrastructure. The definitions of these docker images can be found in the edgexfoundry/ci-build-images Github repository.

Docker Tags Used: Version, Latest


Retention Policy: 180 days since last download

Contains: Docker images built for potential release and testing purposes during development.

Docker Tags Used: Version (ie: v1.x), Release Branch (master, fuji, etc), Latest


Retention Policy: No automatic removal. Requires TSC approval to remove images from this repository.

Contains: Officially released docker images for EdgeX.

Docker Tags Used:•Version (ie: v1.x), Latest

Nexus Cleanup Policies Reference

Docker Compose Files

Tied to Code Release? Yes

Docker compose files are released alongside the docker images for every release of EdgeX Foundry. During development the community maintains compose files a folder named nightly-build. These compose files are meant to be used by our testing frameworks. At the time of release the community makes compose files for that release in a folder matching it's name. (ie: geneva)

DockerHub Image Descriptions and Overviews

Tied to Code Release? No

After Docker images are published to DockerHub, automation should be run to update the image Overviews and Descriptions of the necessary images. This automation is located in the edgex-docker-hub-documentation branch of the cd-management repository. In preparation for the release the community makes changes to the Overview and Description metadata as appropriate. The Release Czar will coordinate the execution of the automation near the release time.

Github Page: EdgeX Docs

Tied to Code Release? No

EdgeX Foundry releases a set of documentation for our project at This page is a Github page that is managed by the edgex/foundry/edgex-docs Github repository. As a community we make our best effort to keep these docs up to date. On this page we are also versioning the docs with the semantic versions of the named releases. As a community we try to version our documentation site shortly after the official release date but documentation changes are addressed as we find them throughout the release cycle.

GitHub Tags

Tied to Code Release? Yes, for the final semantic version

Github tags are used to track the releases of EdgeX Foundry. During development the tags are incremented automatically for each commit using a development suffix (ie: v1.1.1-dev.1 -> v1.1.1-dev.2). At the time of release we release a tag with the final semantic version (ie: v1.1.1).


Tied to Code Release? Yes

The building of snaps was removed from community scope in September 2020 but are still available on the snapcraft store.

Canonical publishes daily arm64 and amd64 releases of the following snaps to latest/edge in the Snap Store. These builds take place on the Canonical Launchpad platform and use the latest code from the master branch of each EdgeX repository, versioned using the latest git tag.

edgexfoundry edgex-app-service-configurable edgex-device-camera edgex-device-rest edgex-device-modbus edgex-device-mqtt edgex-device-grove edgex-cli (work-in-progress) Note - this list may expand over time.

At code freeze the edgexfoundry snap revision in the edge channel is promoted to latest/beta and $TRACK/beta. Publishing to beta will trigger the Canonical checkbox automated tests, which include tests on a variety of hardware hosted by Canonical.

When the project tags a release of any of the snaps listed above, the resulting snap revision is first promoted from the edge channel to latest/candidate and $TRACK/candidate. Canonical tests this revision, and if all looks good, releases to latest/stable and $TRACK/stable.

Canonical may also publish updates to the EdgeX snaps after release to address high/critical bugs and CVEs (common vulnerabilities and exposures).

Note - in the above descriptions, $TRACK corresponds to the named release tracks (e.g. fuji, geneva, hanoi, ...) which are created for every major/minor release of EdgeX Foundry.

SwaggerHub API Docs

Tied to Code Release? No

In addition to our documentation site EdgeX foundry also releases our API specifications on Swaggerhub.

Testing Framework

Tied to Code Release? Yes

The EdgeX Foundry community has a set of tests we maintain to do regression testing during development this framework is tracking the master branch of the components of EdgeX. At the time of release we will update the testing frameworks to point at the released Github tags and add a version tag to the testing frameworks themselves. This creates a snapshot of testing framework at the time of release for validation of the official release.

GitHub Release Artifacts

Tied to Code Release? Yes

GitHub release functionality is utilized on some repositories to release binary artifacts/assets (e.g. zip/tar files). These are versioned with the semantic version and found on the repository's GitHub Release page under 'Assets'.

Known Build Dependencies for EdgeX Foundry

There are some internal build dependencies within the EdgeX Foundry organization. When building artifacts for validation or a release you will need to take into the account the build dependencies to make sure you build them in the correct order.

Known EdgeX Foundry Build Dependencies

  • Application services have a dependency on the Application Functions SDK.
  • Go Device services have a dependency on the Go Device SDK.
  • C Device services have a dependency on the C Device SDK.



This document is meant to be a living document of all the release artifacts of EdgeX Foundry. With this ADR we would have a good understanding on what needs to be released and when they are released. Without this document this information will remain tribal knowledge within the community.
