MicroService Proxy Gateway Solutions

Kong, Traefik, Caddy, Linkerd, Fabio, Vulcand, and Netflix Zuul seem to be the most common in microservice proxy/gateway solutions. Kubernetes Ingress is often a simple Ngnix, which is difficult to separate the popularity from other things.

Send docker logs to ELK through gelf log driver

There's so many way to send logs to an elk... logspout, filebeat, journalbeat, etc.

But docker has a gelf log driver and logstash a gelf input. So here we are.

Here is a docker-compose to test a full elk with a container sending logs via gelf.

With Docker 1.8.0 shipped new log-driver for GELF via UDP, this means that the logs from Docker Container(s) can be shipped directly to the ELK stack for further analysis.
This tutorial will illustrate how to use the GELF log-driver with Docker engine.
Step 1: Setup ELK Stack:
- docker run -d --name es elasticsearch
- docker run -d --name logstash --link es:elasticsearch logstash -v /tmp/logstash.conf:/config-dir/logstash.conf logstash logstash -f /config-dir/logstash.conf
- Note the config for Logstash can be found at this link
- docker run --link es:elasticsearch -d kibana
Once the ELK stack is up now let's fire up our nginx container which ships its logs to ELK stack.

LOGSTASH_ADDRESS=$(docker inspect --format '{{ .NetworkSettings.IPAddress }}' logstash)
`docker run -d --net=host --log-driver=gelf --log-opt gelf-address=u

NGINX Tuning For Best Performance

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.

Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.

You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.

(C-x means ctrl+x, M-x means alt+x)

Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

remap prefix to Control + a
