Docker ELK stack

Run the ELK (Elasticseach, Logstash, Kibana) stack with Docker and Docker-compose.

It will give you the ability to quickly test your logstash filters and check how the data can be processed in Kibana.

Based on the 3 following Docker images:

• elk-elasticsearch
• elk-logstash
• elk-kibana

HOW TO

Setup

1. Install Docker.
2. Install Docker-compose.
3. Clone this repository

SELinux

On distributions which have SELinux enabled out-of-the-box you will need to either re-context the files or set SELinux into Permissive mode in order for fig-elk to start properly. For example on Redhat and CentOS, the following will apply the proper context:

.-root@centos ~
`-$ chcon -R system_u:object_r:admin_home_t:s0 fig-elk/

Usage

Start the stack and inject logs

First step, you can edit the logstash-configuration in logstash-conf/logstash.conf. You can add filters you want to test for example.

Then, start the ELK stack using docker-compose:

$ docker-compose up

You can also choose to run it in background (detached mode):

$ docker-compose up -d

Now that the stack is running, you'll want to inject logs in it. The shipped logstash configuration allows you to send content via tcp:

$ nc localhost 5000 < /path/to/logfile.log

Playing with the stack

The stack exposes 4 ports on your localhost:

• 5000: Logstash TCP input.
• 9200: Elasticsearch HTTP (with Marvel plugin accessible via http://localhost:9200/_plugin/marvel)
• 8080: Kibana 3 web interface, access it via http://localhost:8080
• 5601: Kibana 4 web interface, access it via http://localhost:5601

Boot2docker

If you're using boot2docker, you must access it via the boot2docker IP address:

• http://boot2docker-ip-address:9200/_plugin/marvel to access the Marvel plugin.
• http://boot2docker-ip-address:8080 to use Kibana 3.
• http://boot2docker-ip-address:5601 to use Kibana 4.
