Dockerize Logstash, Redis setup

Question

Have a Logstash process using file as input sending events to Redis and from there to second Logstash process and over to custom http process. So, Logstash --> Redis --> Logstash --> Http In order to dockerize the setup I was thinking of keeping Logstash --> Redis on one container and linking that with Redis --> Http which will be on another container. Am still new to Docker & Would highly appreciate any inputs / feedback on the same.

Answer 1

Here's my opinion of how I would go about this. One Logstash image that maybe takes the configuration through a mapped volumn or even a passed Env Parameter that switchs between file input and redis input.

So you would have two Logstash containers, from the same image one takes input form a file and pushes it to redis and the second from redis and puts it out to your http interface.

And a Redis Container that acts as a go between/cache.

Hope this makes sense.
