Play with Docker Shinken

There are many way to try out Docker Shinken, a really slick one is creating a stack on Play with Docker.

Login or signup, then create a new instance.

Download a Docker Shinken application definition:

# shinken_basic
curl -Lo docker-compose.yml https://gist.github.com/cornernote/695cc633680df7b5ccfd02ffa6dd5ab0/raw/ab8f36617a636212692cfe4d93b27b5ed873823d/shinken_basic.docker-compose.yml
# shinken_thruk
curl -Lo docker-compose.yml https://gist.github.com/cornernote/695cc633680df7b5ccfd02ffa6dd5ab0/raw/ab8f36617a636212692cfe4d93b27b5ed873823d/shinken_thruk.docker-compose.yml
# shinken_thruk_graphite
curl -Lo docker-compose.yml https://gist.github.com/cornernote/695cc633680df7b5ccfd02ffa6dd5ab0/raw/ab8f36617a636212692cfe4d93b27b5ed873823d/shinken_thruk_graphite.docker-compose.yml

Download the configuration

mkdir configs
curl -Lo configs/docker_shinken.cfg https://gist.github.com/cornernote/695cc633680df7b5ccfd02ffa6dd5ab0/raw/ab8f36617a636212692cfe4d93b27b5ed873823d/docker_shinken.cfg

And start the stack

docker-compose up -d

Your services will be available on their mapped port, just click the label right next to the node IP address.

Login with admin / admin.

Troubleshooting

Missing Port Link

If the link to the exposed port does not show then you can determine it from the SSH link provided. Simply convert the link as follows then visit the page.

Change:

ssh EXAMPLE@direct.labs.play-with-docker.com

To:

http://EXAMPLE-80.direct.labs.play-with-docker.com

Nginx Bad Gateway

If nginx complains about a bad gateway, you may just need to wait about 60 seconds for everything to start up.

It may also be you have an invalid configuration file. See logs below.

Viewing Logs

When all else fails, check the logs.

Container logs:

docker-compose logs -f shinken

Shinken logs:

docker-compose exec shinken bash
tail -f /var/log/shinken/*.log
