Route Docker Logs to ELK Stack
  • 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

Transparent proxy for Docker containers

Transparent proxy for Docker containers

If the Docker host is placed inside a proxy server, it needs to add the proxy configuration to each Dockerfile such as ENV http_proxy.

Following allows transparent access from the container to outside without any proxy configuration.

  1. Set up the transparent proxy
  2. Apply iptables rule for the transparent proxy
