EdgeX Foundry Support Scheduler Service

Go implementation of EdgeX Support Scheduler.

Installation and Execution

To fetch the code and build the microservice execute the following:

cd $GOPATH/src
go get github.com/edgexfoundry/edgex-go
cd $GOPATH/src/github.com/edgexfoundry/edgex-go
# pull the 3rd party / vendor packages
make prepare
# build the microservice
make cmd/support-scheduler/support-scheduler
# get to the support logging microservice executable
cd cmd/support-scheduler
# run the microservice (may require other dependent services to run correctly)
./support-scheduler

To test, simple run:

cd $GOPATH/src
go get github.com/edgexfoundry/edgex-go
# pull the 3rd party / vendor packages
make prepare
# build the microservice
make cmd/support-scheduler/support-scheduler
# exectute the go test(s)
go test

Install and Deploy via Docker Container

This project has facilities to create and run Docker containers. A Dockerfile is included in the repo. Make sure you have already run make prepare to update the dependecies. To do a Docker build using the included Docker file, run the following:

Prerequisites

See https://docs.docker.com/install/ to learn how to obtain and install Docker.

Installation and Execution
cd $GOPATH/src
go get github.com/edgexfoundry/edgex-go
cd $GOPATH/src/github.com/edgexfoundry/edgex-go
# To create the Docker image
sudo make docker_support_scheduler
# To create a containter from the image
sudo docker create --name "[DOCKER_CONTAINER_NAME]" --network "[DOCKER_NETWORK]" [DOCKER_IMAGE_NAME]
# To run the container
sudo docker start [DOCKER_CONTAINER_NAME]

Note - creating and running the container above requires Docker network setup, may require dependent containers to be setup on that network, and appropriate port access configuration (among other start up parameters). For this reason, EdgeX recommends use of Docker Compose for pulling, building, and running containers. See The Getting Started Guides for more detail.
