Docker ELK Stack

Credit to deviantony/docker-elk for a great starting point.

Setup

Run this script:

sudo yum install -y yum-utils
sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo/docker.repo
sudo yum install -y docker-ce python-pip git
sudo systemctl enable docker
sudo systemctl start docker
sudo pip install -U docker-compose
git clone https://github.com/rhefner1/docker-elk-iot.git
sudo sysctl -w vm.max_map_count=262144

Usage

Start the ELK stack using docker-compose:

$ docker-compose up -d

Now that the stack is running, you'll want to inject logs in it. Try running scripts/send_message.py which publishes the message to RabbitMQ. Logstash then receives the message and drops it into Elasticsearch, where it can be viewed with Kibana.

You can access Kibana UI by hitting http://localhost:5601 with a web browser.

By default, the stack exposes the following ports:

• 5000: Logstash TCP input.
• 9200: Elasticsearch HTTP
• 9300: Elasticsearch TCP transport
• 5601: Kibana
• 5672: RabbitMQ

Restarting Services

• If you edit any of the configuration files or mess something up, you'll need to restart the services by following these steps:
  • Run sudo docker-compose stop
  • Run sudo docker-compose build
  • Run sudo docker-compose up -d
• If you want to erase all Elasticsearch data, run this command while services are stopped: sudo rm -rf /es-data
