The DevOps 2.1 Toolkit: Docker Swarm

By: Viktor Farcic

Overview of this book

Viktor Farcic's latest book, The DevOps 2.1 Toolkit: Docker Swarm, takes you deeper into one of the major subjects of his international best seller, The DevOps 2.0 Toolkit, and shows you how to successfully integrate Docker Swarm into your DevOps toolset. Viktor shares with you his expert knowledge in all aspects of building, testing, deploying, and monitoring services inside Docker Swarm clusters. You'll go through all the tools required for running a cluster. You'll travel through the whole process with clusters running locally on a laptop. Once you're confident with that outcome, Viktor shows you how to translate your experience to different hosting providers like AWS, Azure, and DigitalOcean. Viktor has updated his DevOps 2.0 framework in this book to use the latest and greatest features and techniques introduced in Docker. We'll go through many practices and even more tools. While there will be a lot of theory, this is a hands-on book. You won't be able to complete it by reading it on the metro on your way to work. You'll have to read this book while in front of the computer and get your hands dirty.

Setting up LogStash as the logs parser and forwarder


We did E from the ELK stack. Now let's move to L. LogStash requires a configuration file. We'll use one that is already available inside the vfarcic/cloud-provisioning (https://github.com/vfarcic/cloud-provisioning) repository. We’ll create a new directory, copy the conf/logstash.conf (https://github.com/vfarcic/cloud-provisioning/blob/master/conf/logstash.conf) configuration, and use it inside the logstash service:

mkdir -p docker/logstash

cp conf/logstash.conf \
    docker/logstash/logstash.conf

cat docker/logstash/logstash.conf

The content of the logstash.conf file is as follows:

input {
  syslog { port => 51415 }
}

output {
  elasticsearch {
    hosts => ["elasticsearch:9200"]
  }
  # Remove in production
  stdout {
    codec => rubydebug
  }
}

This is a very simple LogStash configuration. If will listen on port 51415 for syslog entries.

Each entry will be sent to two outputs; elasticsearch and stdout. Since both logstash and...
