just fooling around with a simple oklog setup

oklog-compose

This is a simple test setup to experiment with github.com/oklog/oklog.

This needs to be built with go1.8. If you don't have that already, then follow the instructions at https://golang.org/dl/.

To build this, you can just type make to build it - or, if you're using go get to grab the latest golang release, something like this:

# make GO=go1.8rc3
CGO_ENABLED=0 go1.8rc3 build -ldflags="-s -w" github.com/oklog/oklog/cmd/oklog
docker build -t oklog .

If you have a GOPATH setup then that should be respected, otherwise the makefile will set it underneath this repo.

The compose stack here has a logspout container running to grab docker logs on this machine. You can use this to get some logs into oklog by running the following:

docker run --rm ubuntu:latest bash -c 'for i in {1..10}; do date; sleep 1; done'

Then you can query for the logs as follows:

./oklog query --store localhost:10010
