flucky

flucky is a lightweight program written in go for reading data from sensors, for example with a banana or raspberry pi. In addition, flucky provides a REST-API to receive from other flucky installations measured values. All received measured values, no matter if they come directly from flucky or from a server instance of flucky with the provided REST-API, can be stored into a database.

Installation

flucky can be installed over multiple ways. For example over a specific linux distributions package or as container. The following table lists all repositories where flucky can be otained from, but flucky can already be compiled from source code.

Distribution	Repo's
Arch Linux	armv7, x86_64
Debian, Ubuntu, Linux Mint	Currently not supported
RHEL, Fedora, Centos	Planning
Container Image	hub.docker.com

Compiling the source code

An additional ways to install flucky is to compile the source code. There are two different ways to compile flucky from scratch. The easier ways is to use the pre-defined container image, which has included all dependencies to compile flucky. Alternatively, if all dependencies are met, flucky can also be compiled without the container image. Both variants are briefly described.

Compiling the source code via container image

To compile flucky via container image it's necessary, that a container runtime is installed. In the Makefile is predefined docker, but it's can be also used podman. Execute make container-run/flucky to start the compiling process.

$ make container-run/flucky
make container-run COMMAND=flucky
make[1]: Directory „/home/markus/workspace/flucky“ is entered
/usr/bin/docker run \
        --rm \
        --volume /home/markus/workspace/flucky:/workspace \
        volkerraschek/build-image:latest \
                make go-build \
                        VERSION=60ee044-git \
                        GOOS=linux \
                        GOARCH=amd64
go-bindata -pkg db -o ./pkg/db/bindataSQL.go ./pkg/db/sql/***
go-bindata -pkg goldenfiles -o ./test/goldenfiles/bindata.go ./test/goldenfiles/json/***
GOOS=linux \
GOARCH=amd64 \
        go build -ldflags "-X main.version=60ee044-git"

Compiling the source code without container image

Make sure you have installed go >= v1.12. Execute make flucky to compile flucky without a container-image. There should be a similar output as when compiling flucky via the container image.
