How to add config file while pushing default docker image to cloud foundry

Question

As announced the Swisscom logstash buildpack is not supported any longer. The proposed solution is to push the default docker image. I am trying to figure out the way to attach the curator configuration without "baking" it inside the docker image. Any ideas? thanks

There are two articles in the support forum that discuss some aspects of your question here:

https://docs.developer.swisscom.com/service-offerings/logstash-docker.html https://docs.developer.swisscom.com/service-offerings/kibana-docker.html

They do in fact recommend:

If you wish to use configuration files instead, you can fork the official Docker image and ADD your configuration files in your own Dockerfile.

I assume that is exactly what you did not want to do, but you can pass in most of the config via environment variables as far as I understand.

If you are ok with creating a separate Docker image, you could also host the config somewhere (let's say on S3) and then dynamically retrieve it on start-up of your Docker container.

You could also build the config setup into your deployment setup, although I haven't tried this with the docker build-pack, you can "stack" multiple build-packs in CloudFoundry and pre-load your configuration files into the virtual server as part of an initial build-pack step. There is more information on how to do that here: https://docs.cloudfoundry.org/buildpacks/use-multiple-buildpacks.html
