520 Iocage plugin ansible-syslogng

Use case 

Configure and run a log server. Configure log clients and test them. Use syslog-ng. Clone the iocage plugin ansible-syslogng. The project keys are jail’s aliases.

Destroy all jails

(env) > ansible-playbook vbotka.freebsd.pb_iocage_destroy_all_jails.yml \
                         -i iocage.ini \
                         --flush-cache

Fetch the required iocage plugins

(env) > ansible-playbook vbotka.freebsd.pb_iocage_plugins.yml \
                         -i iocage.ini \
                         -t project_plugins \
                         --flush-cache

Create the project

(env) > ansible-playbook vbotka.freebsd.pb_iocage_project_create_from_plugins.yml \
                         -i iocage.ini \
                         -i hosts \
                         --flush-cache

Configure log server

(env) > ansible-playbook pb-logserv.yml -i hosts

Configure log clients

(env) > ansible-playbook pb-logclient.yml -i hosts -i iocage.ini

Test

Synopsis 

At a managed node:

In the playbook vbotka.freebsd.pb_iocage_plugins.yml:
- Fetch the iocage plugin ansible-syslogng
In the playbook vbotka.freebsd.pb_iocage_project_create_from_plugins.yml:
- Clone jails from the iocage plugin ansible-syslogng
In the inventory group logserv_group configure syslog-ng server.
In the inventory group logclient_group configure syslog-ng client.

Requirements 

iocage plugin ansible-syslogng
playbook vbotka.freebsd.pb_iocage_plugins.yml
playbook vbotka.freebsd.pb_iocage_project_create_from_plugins.yml
inventory plugin vbotka.freebsd.iocage
connection plugin vbotka.freebsd.jailexec
module vbotka.freebsd.service
role vbotka.freebsd.postinstall

Notes 

Quoting syslog-ng - FreeBSD Wiki:

One of the most typical use of syslog-ng is central log aggregation. … It collects log messages on TCP port 514 and saves them to directories and files based on sender host name and current date.

Note

The same syslog-ng configuration is used in 521 Iocage plugins ansible-pull-syslogng-*
