Role Name
|
||||
=========
|
||||
|
||||
A brief description of the role goes here.
|
||||
|
||||
Requirements
|
||||
------------
|
||||
|
||||
Any pre-requisites that may not be covered by Ansible itself or the role should be mentioned here. For instance, if the role uses the EC2 module, it may be a good idea to mention in this section that the boto package is required.
|
||||
A role that installs Haproxy, <https://www.haproxy.org>.
|
||||
|
||||
Role Variables
|
||||
--------------
|
||||
|
||||
A description of the settable variables for this role should go here, including any variables that are in defaults/main.yml, vars/main.yml, and any variables that can/should be set via parameters to the role. Any variables that are read from other roles and/or the global scope (ie. hostvars, group vars, etc.) should be mentioned here as well.
|
||||
The most important variables are listed below:
|
||||
|
||||
``` yaml
|
||||
haproxy_latest_release: True
|
||||
haproxy_version: 2.0
|
||||
haproxy_repo_key: 'http://haproxy.debian.net/bernat.debian.org.gpg'
|
||||
haproxy_debian_latest_repo: "deb http://haproxy.debian.net {{ ansible_lsb.codename }}-backports-{{ haproxy_version }} main"
|
||||
haproxy_ubuntu_latest_repo: "ppa:vbernat/haproxy-{{ haproxy_version }}"
|
||||
haproxy_pkg_state: latest
|
||||
haproxy_enabled: True
|
||||
haproxy_k_bind_non_local_ip: True
|
||||
|
||||
haproxy_default_port: 80
|
||||
haproxy_terminate_tls: False
|
||||
haproxy_ssl_port: 443
|
||||
haproxy_admin_port: 8880
|
||||
haproxy_admin_socket: /run/haproxy/admin.sock
|
||||
|
||||
haproxy_letsencrypt_managed: True
|
||||
haproxy_cert_dir: '{{ pki_dir }}/haproxy'
|
||||
|
||||
haproxy_nagios_check: False
|
||||
# It's a percentage
|
||||
haproxy_nagios_check_w: 70
|
||||
haproxy_nagios_check_c: 90
|
||||
|
||||
haproxy_check_interval: 3s
|
||||
haproxy_backend_maxconn: 2048
|
||||
|
||||
haproxy_sysctl_conntrack_max: 131072
|
||||
```
|
||||
|
||||
Additional tasks
|
||||
------------
|
||||
|
||||
The user of this role will need to write a haproxy.cfg template and install it with a dedicated task. Something like
|
||||
|
||||
```yaml
|
||||
- name: Configure haproxy
|
||||
template: src=haproxy.cfg.j2 dest=/etc/haproxy/haproxy.cfg owner=root group=haproxy mode=0440
|
||||
notify: Reload haproxy
|
||||
tags: [ 'haproxy', 'haproxy_conf' ]
|
||||
```
|
||||
|
||||
Dependencies
|
||||
------------
|
||||
|
||||
A list of other roles hosted on Galaxy should go here, plus any details in regards to parameters that may need to be set for other roles, or variables that are used from other roles.
|
||||
|
||||
Example Playbook
|
||||
----------------
|
||||
|
||||
Including an example of how to use your role (for instance, with variables passed in as parameters) is always nice for users too:
|
||||
|
||||
- hosts: servers
|
||||
roles:
|
||||
- { role: username.rolename, x: 42 }
|
||||
* letsencrypt-acme-sh

NAME
|
||||
$me - check haproxy stats for errors, using UNIX socket interface
|
||||
|
||||
SYNOPSIS
|
||||
$me [OPTIONS]
|
||||
|
||||
DESCRIPTION
|
||||
Get haproxy statistics via UNIX socket and parse information searching for errors.
|
||||
|
||||
OPTIONS
|
||||
-c, --critical
|
||||
Set critical threshold for sessions number (chacks current number of sessions
|
||||
against session limit, if enforced) to the specified percentage.
|
||||
If no session limit (slim) was specified for the given proxy, this option has
|
||||
no effect.
|
||||
|
||||
-d, --dump
|
||||
Just dump haproxy stats and exit;
|
||||
|
||||
-h, --help
|
||||
Print this message.
|
||||
|
||||
-p, --proxy
|
||||
Check only named proxies, not every one. Use comma to separate proxies
|
||||
in list.
|
||||
|
||||
-s, --sock, --socket
|
||||
Use named UNIX socket instead of default (/run/haproxy/admin.sock)
|
||||
|
||||
-w, --warning
|
||||
Set warning threshold for sessions number to the specified percentage (see -c)
|
||||
|
||||
CHECKS AND OUTPUT
|
||||
$me checks every proxy (or the named ones, if -p was given)
|
||||
for status. It returns an error if any of the checked FRONTENDs is not OPEN,
|
||||
any of the checked BACKENDs is not UP, or any of the checkes servers is not UP;
|
||||
$me reports any problem it found.
|
||||
|
||||
EXAMPLES
|
||||
$me -s /var/spool/haproxy/sock
|
||||
Use /var/spool/haproxy/sock to communicate with haproxy.
|
||||
|
||||
$me -p proxy1,proxy2 -w 60 -c 80
|
||||
Check only proxies named "proxy1" and "proxy2", and set sessions number
|
||||
thresholds to 60% and 80%.

HAProxy OCSP Stapling Updater - $VERSION
|
||||
Copyright (c) 2015 Pier Carlo Chiodi - http://www.pierky.com
|
||||
|
||||
https://github.com/pierky/haproxy-ocsp-stapling-updater
|
||||
|
||||
Usage:
|
||||
$PROGNAME [options] --cert crt_full_path
|
||||
|
||||
This script extracts and queries the OCSP server present in a
|
||||
certificate to obtain its revocation status, then updates HAProxy by
|
||||
writing the '.issuer' and the '.ocsp' files and by sending it the
|
||||
'set ssl ocsp-response' command through the local UNIX admin socket.
|
||||
|
||||
The crt_full_path argument is the full path to the certificate bundle
|
||||
used in haproxy 'crt' setting. End-entity (EE) certificate plus any
|
||||
intermediate CA certificates must be concatenated there.
|
||||
An OCSP query is sent to the OCSP server given on the command line
|
||||
(--ocsp-url and --ocsp-host argument); if these arguments are missing,
|
||||
URL and Host header values are automatically extracted from the
|
||||
certificate.
|
||||
If the '.issuer' file already exists it's used to build the OCSP
|
||||
request, otherwise the chain is extracted from crt_full_path and used
|
||||
to identify the issuer.
|
||||
Finally, it writes the related '.issuer' and .'ocsp' files and updates
|
||||
haproxy, using 'socat' and the local UNIX socket (--socket argument,
|
||||
default $HAPROXY_ADMIN_SOCKET_DEFAULT).
|
||||
|
||||
Exit codes:
|
||||
0 OK
|
||||
1 openssl certificates handling error
|
||||
2 OCSP server URL not found
|
||||
3 string parsing / PEM manipulation error
|
||||
4 OCSP error
|
||||
5 haproxy management error
|
||||
9 program error (wrong arguments, missing dependencies)
|
||||
|
||||
Options:
|
||||
|
||||
-d, --debug : don't do anything, print debug messages only.
|
||||
|
||||
--keep-temp : keep temporary directory after exiting (for
|
||||
debug purposes).
|
||||
|
||||
-g, --good-only : do not update haproxy if OCSP response
|
||||
certificate status value is not 'good'.
|
||||
|
||||
-l, --syslog priority : log errors to syslog system log module.
|
||||
The priority may be specified numerically
|
||||
or as a facility.level pair (e.g.
|
||||
local7.error).
|
||||
|
||||
--ocsp-url url : OCSP server URL; use this instead of the
|
||||
one in the EE certificate.
|
||||
|
||||
--ocsp-host host : OCSP server hostname to be used in the
|
||||
'Host:' header; use this instead of the one
|
||||
extracted from the OCSP server URL.
|
||||
|
||||
--partial-chain : Allow partial certificate chain if at least one certificate
|
||||
is in trusted store. Useful when validating an intermediate
|
||||
certificate without the root CA.
|
||||
|
||||
-s, --socket file : haproxy admin socket. If omitted,
|
||||
$HAPROXY_ADMIN_SOCKET_DEFAULT is used by default.
|
||||
This script is distributed with only one
|
||||
method to update haproxy: using 'socat'
|
||||
with a local admin-level UNIX socket.
|
||||
Feel free to implement other mechanisms as
|
||||
needed! The right section in the code is
|
||||
\"UPDATE HAPROXY\", at the end of the script.
|
||||
|
||||
-v, --VAfile file : same as the openssl ocsp -VAfile option
|
||||
with 'file' as argument. For more details:
|
||||
'man ocsp'.
|
||||
If file = \"-\" then the chain extracted
|
||||
from the certificate's bundle (or .issuer
|
||||
file) is used (useful for OCSP responses
|
||||
that don't include the signer certificate).
|
||||
|
||||
--noverify : Do not verify OCSP response.
|
||||
|
||||
-S, --skip-update : Do not notify haproxy of the new OCSP response.
|
||||
|
||||
-h, --help : this help."
