Logspout plugins

[marcinmantke]

Hi! Do you have any plans to add an option to install logspout plugins? I'd love to use logspout-gelf but it doesn't seem to be possible right now.

As far as I understand it, plugins are installed at image build time and thus out of scope for this plugin. However, dokku-logspout could be easily modified to support any image name. Thus, you could build a custom container (or choose one that is already out there on hub), set some config, run dokku logspout:update and be up and running.

I'd probably accept a PR that did something like the following:

• rename the following vars thusly
  DOKKU_LOGSPOUT_DEFAULT_IMAGE_VERSION => DOKKU_LOGSPOUT_DEFAULT_IMAGE
DOKKU_LOGSPOUT_IMAGE_VERSION => DOKKU_LOGSPOUT_IMAGE
• set DOKKU_LOGSPOUT_DEFAULT_IMAGE=gliderlabs/logspout:v3.2
• replaces cases of gliderlabs/logspout:${DOKKU_LOGSPOUT_IMAGE_VERSION} with ${DOKKU_LOGSPOUT_IMAGE}
