ansible-graphite's Introduction

nsg.graphite

This role installs graphite, I choose to install graphite from pip because the packages in the distributions repositories are old and features are missing. I’m using apt/yum when possible.

Galaxy

The Role in Ansible Galaxy is old and unmaintained because invasive permissions asked by Ansible.

Requirements

As usual, read the tasks and make sure this role will not breaks your installation, I will for example mess with django, twisted and uwsgi.

This role exposes the graphite web interface with uwsgi at localhost:3031, you need to configure a web server your self to talk to that. For example, do this with nginx:

server {
  listen 8080;
  charset utf-8;
  access_log /var/log/nginx/graphite.access.log;
  error_log /var/log/nginx/graphite.error.log;

  location /static {
    alias /opt/graphite/webapp/content;
    expires max;
  }

  location / {
    include uwsgi_params;
    uwsgi_pass 127.0.0.1:3031;
  }
}

The uwsgi socket can be configured through uwsgi_graphite_socket.

Alternatively, you can define uwsgi_graphite_extraopts with additional uwsgi configuration, which can e.g. enable http on port 8080 or add basic auth:

uwsgi_graphite_extraopts:
  - option: http
    value: "{{ ansible_default_ipv4.address }}:8080"
  - option: plugins
    value: router_basicauth
  - option: route
    value: "^/ basicauth:myRealm,foo:bar"

Role Variables

See: defaults/main.yml

New release required for ansible galaxy

Hi, any change you can make a new tag so it is picked up in ansible galaxy? at the moment I am using the repo rather than ansible-galaxy

Thanks in advance, and keep up the good work! :)

Problem with ansible 2 and uwsgi

Did a fresh install on Debian 8.3 on DO with latest Ansible and got a internal server error in the browser. If I do a identical install but use the good old version 1.9 everything works. Investigate.

Move vars/main.yml to defaults

Hi,

I'm trying to install a different graphite version but when adding the version to graphite_install_requirements it get's overridden by the var defined in vars/main.yml.

Am I missing a way to add the requirements to that variable or somehow override it with my own variable?

I currently set the following in the group_vars named graphite:

graphite_install_version: 1.0.2
graphite_install_requirements:
  1.0.2:
    - Django==1.11
    - django-tagging==0.4.3
    - cairocffi==0.8.0
    - pytz==2017.2
    - scandir=1.5
    - python-memcached==1.47
    - txAMQP==0.6.2
    - gunicorn==19.7.0

But when running the role with the following inventory:

- hosts: graphite
  roles:
    - role: nsg.graphite

The variable graphite_install_requirements during runtime is (i've added a debug var statement to the role):

TASK [nsg.graphite : debug] ****************************************************
ok: [192.168.50.2] => {
    "graphite_install_requirements": {
        "0.9.15": [
            "Django==1.4",
            "python-memcached==1.47",
            "txAMQP==0.4",
            "simplejson==2.1.6",
            "django-tagging==0.3.1",
            "gunicorn==19.6.0",
            "pytz==2016.7",
            "cairocffi==0.7.2",
            "whisper==0.9.13",
            "whitenoise==3.2.2",
            "graphite-web==0.9.15",
            "carbon==0.9.15"
        ]
    }
}

Hope you can help me with this

Instead of sudo/sudo_user, use become/become_user and

systemctl: not found

I am trying to install graphite using your role on Debian Jessie.
I am using defaults for most options except user and passwords.
Here is the error I get from the Relaod systemd if unit file has changed:

fatal: [monitoring.curuba.fr]: FAILED!

Any idea?

Thanks in advance
