A tool to generate yaml code for hieradata from APPUiO routes to configure

Project description

Overview

appuio_routes_monitoring is a tool to generate yaml code for hieradata from APPUiO routes to configure http icinga2 monitoring checks for those routes. However the script should work on any openshift cluster.

appuio_routes_monitoring

appuio_routes_monitoring expects the oc to be in the path variable and you need to be logged in to APPUiO before calling this script.

By default the script will generate yaml code for all routes the logged in user has access to. Routes created by ACME integration are ignored.

See usage section of this document for details.

Dependencies

appuio_routes_monitoring supports python >=3.4 and has the following 3rd-party dependencies

appuio_routes_monitoring further relies on the oc binary to extract the routes from the openshift cluster.

Installation

appuio_routes_monitoring can be easily installed using pip: pip install appuio_routes_monitoring

Configuration

appuio_routes_monitoring does not have any configuration files. But it does rely on the oc binary and valid session to APPUiO. Furthermore the script reads annotations from the routes to generate the appropriate yaml code. Currently the following annotations are supported:

monitoring/enabled

Setting this annotation to false will not create an entry for this route.

monitoring/alert_customer

Setting this annotation on the route to true, will set the alert_customer variable to true as well. This will configure the http check to alert to the defined e-mail address.

monitoring/alert_vshn: ‘true’

Setting this annotation on the route to true, will set the production_level of the check to 4, making the check a 24/7 check. This means VSHN will be alerted anytime the check fails.

monitoring/path

Setting this annotation on the route to a URI, will set the http_uri to the specified path. If the annoation is missing, and no route path is set, the http_uri will default to /.

Usage

usage: generate_monitoring_check [-h] [-p PROJECTS [PROJECTS ...]] [-k HIERAKEY]

generate hieradata from appuio routes

optional arguments:
  -h, --help            show this help message and exit
  -p PROJECTS [PROJECTS ...], --project PROJECTS [PROJECTS ...]
  -k HIERAKEY, --key HIERAKEY

Examples

Generate yaml code for project my-test-project

generate_monitoring_check -p my-test-project
profile_icinga2::hiera_httpchecks:
    test-project.example.com:
        display_name: test-project.example.com on APPUiO in my-test-project
        http_address: test-project.example.com
        http_ssl: true
        http_uri: /
        vars:
            alert_customer: false
    test-project.example.com:a:b:
        display_name: test-project.example.com/a/b on APPUiO in my-test-project
        http_address: test-project.example.com
        http_ssl: true
        http_uri: /a/b
        vars:
            alert_customer: false
    test-project.example.com:a:b:c:
        display_name: test-project.example.com/a/b/c on APPUiO in my-test-project
        http_address: test-project.example.com
        http_ssl: true
        http_uri: /a/b/c/status
        vars:
            alert_customer: false
