ansible-microservice-hackathon

During the WarsJava microservice hackathon we will need to provision:

log monitoring (log server)

  • elasticsearch
  • redis
  • logstash
  • kibana

metrics collecting (metrics server)

  • graphite
  • graphana

microservice related stuff (app server)

  • zookeeper
  • logstash-forwarder

deployment related infrastructure: (deploy server)

  • nexus

Playbooks:

Log monitoring

After provisioning just access http://IP_OF_YOUR_HOST with mylogger username and mylogger pass

Instalation

If you provide tag

-t loggers

then you'll provision the module as a whole.

Example of a command to run it (assuming that you have a host inventory file):

ansible-playbook -i hosts microservice_hackathon.yml -vvvv -t "loggers"

SSL keys

Generate SSL keys by running:

openssl req -x509 -batch -nodes -newkey rsa:2048 -keyout logstash-forwarder.key -out logstash-forwarder.crt

Copy the resultant .key and .crt files to

$ROOT/files/certs

You can also execute the provided script to do that:

generate_keys.sh

Metrics monitoring

After provisioning you can access

  • graphite at http://IP_OF_YOUR_HOST
  • graphana at http://IP_OF_YOUR_HOST:8080

Instalation

You have to provide graphite url as presented below (even if it is the same address as the server you are provisioning):

--extra-vars graphite_url=IP_OF_YOUR_HOST

to provision these modules. If you provide tag

-t graphite

then you'll provision the module as a whole.

Example of a command to run it (assuming that you have a host inventory file) with graphite_url variable:

ansible-playbook -i hosts microservice_hackathon.yml -vvvv -t "graphite" --extra-vars graphite_url=59.98.12.123

Applications

Example of a command to run it (assuming that you have a host inventory file) with graphite_url variable:

ansible-playbook -i hosts microservice_hackathon.yml -vvvv -t "apps" --extra-vars logstash_domain=59.98.12.123

JDK8

playbook from: https://gist.github.com/gbirke/8314571

logstash forwarder

installed as a service that logs to syslog

Deployment - nexus

After provisioning you can access Nexus at http://IP_OF_YOUR_HOST:8081/nexus/#welcome

Installation

If you provide tag

-t nexus

then you'll provision the module as a whole.

Example of a command to run it (assuming that you have a host inventory file):

ansible-playbook -i hosts microservice_hackathon.yml -vvvv -t "loggers"
