examples

This repository contains minimal examples for the usage of EdgeFarm.

• Export data from EdgeFarm.network
• Mount directory into an edgefarm application

Building yourself

Note: this is tested with linux kernel >= 5.0.0 and is not guaranteed to work with a lower kernel version!

Setup

In order to build the demo docker images, you need to have docker installed on your system. You can modify the demos and build the container image yourself. To specify the location of the docker image, you can modify the variable DOCKER_REGISTRY in the file default.env.

Before building the containe image run docker login [your-registry] to allow pushing to your registry. If you are using docker hub, login with docker login.

Building

To list all examples build targets run

$ ./dobi.sh list -t examples
[job: version] /gen/gitversion/ Start
Generation complete.
[job: version] /gen/gitversion/ Done
Resources:
  build-and-push-publish-export-data            -> builds and pushes publish-export-data multiarch docker image
  build-and-push-rw-files                       -> builds and pushes rw-files multiarch docker image

To build the docker images run

./dobi.sh build-and-push-<application-name>

The build job registers qemu-user-static to run programs for foreign CPU architectures like arm64 or arm.

Once the build has finished, your docker images are located at the speficied docker registry.

Cleaning up

You can cleanup qemu-user-static using ./dobi.sh uninstall-qemu-user-static.

To check if all qemu emulators have been removed successful, please run ./dobi.sh check-qemu-user-static
