A logging driver for docker

This is a docker logging plugin in its simplest form. You can compile and build the plugin from source and install it using the following 3 steps.

Since the Dockerfile uses scratch image, you need to cross compile the code for linux with all the dependencies installed

$ CGO_ENABLED=0 GOOS=linux go build -a -installsuffix cgo -o docker-logging-driver .

Build an image:

$ docker build -t docker-logging-plugin .

Create a temporary container:

$ docker container create —name tmp docker-logging-plugin

Create a plugin directory to put compiled resources:

$ mkdir -p ./plugin/rootfs

Export rootfs to the plugin directory:

$ docker container export tmp | tar -x -C ./plugin/rootfs

$ cp config.json ./plugin/
$ ls ./plugin
config.json 	rootfs/

$ docker plugin create jayantsinha/docker-logging-plugin ./plugin
$docker plugin ls
