Eureka Templating Library

About

eureka_template - library to generate files from eureka information

This library helps you generate files based on jinja2 templates based on information retrieved from Eureka

Installation

eureka_template can be installed using the pip distribution system for python by issuing:

$ pip install eureka_template

Alternatively, you can run use setup.py to install by cloning this repository and issuing:

# python setup.py install

Examples

Create a file named template.conf.tmpl:

[
{% for app in apps %}
  {
  "name": "{{ app.name }}",
  "instances": [
  {% for instance in app.instances %}
    {
    "hostName": "{{ instance.hostname }}",
    "port": {{ instance.port }}
    }{% if not loop.last %},{% endif %}
  {% endfor %}
  ]
  }{% if not loop.last %},{% endif %}
{% endfor %}
]

Then execute:

eureka-template -e http://eureka.example.com/eureka/v2/ \
-t template.conf.tmpl \
-o /dev/stdout

You’ll see your template filled with data on the screen.

It will keep running and polling eureka and will generate a new template any time there’s a change.

You can specify a command to execute whenever the template is generated by using the -c flag

eureka-template -e http://eureka.example.com/eureka/v2/ \
-t template.conf.tmpl \
-o /dev/stdout
-c "echo hi"

You can also run it and exit immediately:

eureka-template -e http://eureka.example.com/eureka/v2/ \
-t template.conf.tmpl \
-o /dev/stdout \
-c "echo hi" \
--once
