If you follow the right Oracle people, you probably already know that Oracle just released Oracle Linux Automation Manager:
Your #Ansible automation engine might be already there, included with your Oracle Linux subscription... https://t.co/RPZw37yOvs pic.twitter.com/aQZInFcUsv

My understanding was that access to it required ULN access, so there was no way to just spin up a quick VM at home and try it out... but I was wrong.
As confirmed by Ludovico, there is public access:
I might have talked too early, it looks like a public repo is also available:https://t.co/XxZhs9oFDi

I thought I will keep it simple for now, so I just created a VM with Vagrant and confirm you can test it out from home from that public repository.
First, add and enable the Automation public repository to your system:
[root@OracleAuto ~]# dnf config-manager --add-repo http://yum.oracle.com/repo/OracleLinux/OL8/automation/x86_64

The automation package installation is fairly simple (for a default/test configuration, of course) and you can see an example below copied from the Oracle documentation:
Installing Oracle Linux Automation Manager

Next, we need to setup the configuration using AWX user.
Again, just following the documentation example:
[root@OracleAuto ~]# cat /etc/redis.conf
[...]
unixsocket /var/run/redis/redis.sock
unixsocketperm 775
[root@OracleAuto ~]# /var/lib/ol-automation-manager/ol-automation-manager-DB-init.sh

Let's now create the management user and make sure you set the correct hostname/IP address for the "AWX Instance provision"
[awx@OracleAuto ~]$ awx-manage createsuperuser --username admin
Email address: admin@test.com
Password:
Password (again):
Superuser created successfully.
[awx@OracleAuto ~]$
[awx@OracleAuto ~]$ awx-manage create_preload_data
Default organization added.
Demo Credential, Inventory, and Job Template added.
(changed: True)
[awx@OracleAuto ~]$ awx-manage provision_instance --hostname=OracleAuto
Successfully registered instance OracleAuto
(changed: True)
[awx@OracleAuto ~]$ awx-manage register_queue --queuename=tower --hostnames=OracleAuto
Creating instance group tower
Added instance OracleAuto to tower
(changed: True)
[awx@OracleAuto ~]$
[awx@OracleAuto ~]$ exit
logout
Once that is completed, we need to setup the HTTP server.
Since this is just a test, you can just create a ssl certicate to avoid issues login into your management interface (please, dont do this on your produciton system :) )
[root@OracleAuto ~]# openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/tower/tower.key -out /etc/tower/tower.crt
Generating a RSA private key
......+++++
.+++++
writing new private key to '/etc/tower/tower.key'
-----
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) [XX]:
State or Province Name (full name) []:
Locality Name (eg, city) [Default City]:
Organization Name (eg, company) [Default Company Ltd]:
Organizational Unit Name (eg, section) []:
Common Name (eg, your name or your server's hostname) []:
Email Address []:
[root@OracleAuto ~]#
I'm sure you can change the web server to your favourite one, but for now, we will setup nginx server that is the default one.
Here, we just made a backup of the default configuration and copied the default configuration from the documentation:
[root@OracleAuto ~]# mv /etc/nginx/nginx.conf /etc/nginx/nginx.conf.bk
[root@OracleAuto ~]# nano /etc/nginx/nginx.conf
[root@OracleAuto ~]# cat /etc/nginx/nginx.conf
user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;
# Load dynamic modules. See /usr/share/doc/nginx/README.dynamic.
include /usr/share/nginx/modules/*.conf;
events {
worker_connections 1024;
}
http {
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log /var/log/nginx/access.log main;
sendfile on;
tcp_nopush on;
tcp_nodelay on;
keepalive_timeout 65;
types_hash_max_size 2048;
include /etc/nginx/mime.types;
default_type application/octet-stream;
# Load modular configuration files from the /etc/nginx/conf.d directory.
# See http://nginx.org/en/docs/ngx_core_module.html#include
# for more information.
include /etc/nginx/conf.d/*.conf;
}
[root@OracleAuto ~]#
Last steps, just change some information on the tower setting file (just add your hostname/IP into CLUSTER_HOST_ID) and enable/start the Oracle Automation Manager Service with Systemd
[root@OracleAuto ~]# grep -i CLUSTER_HOST_ID /etc/tower/settings.py
CLUSTER_HOST_ID = "OracleAuto"
[root@OracleAuto ~]#
[root@OracleAuto ~]# systemctl enable --now ol-automation-manager.service
Created symlink /etc/systemd/system/multi-user.target.wants/ol-automation-manager.service → /usr/lib/systemd/system/ol-automation-manager.service.
[root@OracleAuto ~]#
And voilà! you can now start managing your ansible playbooks directly from Oracle Automation Manager Interface
I really need to get more into Ansible and Automation, so this is could be a good way to start using Oracle own Automation manager :)
