Om du följer rätt Oracle-personer vet du förmodligen redan att Oracle precis släppte Oracle Linux Automation Manager:
Din #Ansible automationsmotor kanske redan finns där, inkluderad med din Oracle Linux-prenumeration... https://t.co/RPZw37yOvs pic.twitter.com/aQZInFcUsv

Jag förstod att åtkomst till det krävde ULN-åtkomst, så det fanns inget sätt att bara snurra upp en snabb VM hemma och prova den... men jag hade fel.
Som bekräftats av Ludovico finns det allmän tillgång:
Jag kanske har pratat för tidigt, det verkar som att en offentlig repo också är tillgänglig:https://t.co/XxZhs9oFDi

Jag tänkte att jag ska hålla det enkelt tills vidare, så jag skapade bara en virtuell dator med Vagrant och bekräftar att du kan testa den hemifrån från det offentliga förrådet.
Lägg först till och aktivera det offentliga förrådet Automation till ditt system:

Installationen av automationspaketet är ganska enkel (för en standard-/testkonfiguration, naturligtvis) och du kan se ett exempel nedan kopierat från Oracle-dokumentationen:
Installera Oracle Linux Automation Manager
[root@OracleAuto ~]# dnf install ol-automation-manager

Låt oss nu skapa hanteringsanvändaren och se till att du ställer in rätt värdnamn/IP-adress för "AWX Instance provision"

När det är klart måste vi konfigurera HTTP-servern.
Eftersom detta bara är ett test kan du bara skapa ett ssl-certifikat för att undvika problem med inloggning i ditt hanteringsgränssnitt (snälla, gör inte detta på ditt produktionssystem :) )
[root@OracleAuto ~]# openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/tower/tower.key -out /etc/tower/tower.crt

Jag är säker på att du kan ändra webbservern till din favorit, men för närvarande kommer vi att ställa in nginx-servern som är standardservern.
Här har vi precis gjort en säkerhetskopia av standardkonfigurationen och kopierat standardkonfigurationen från dokumentationen:
[root@OracleAuto ~]# mv /etc/nginx/nginx.conf /etc/nginx/nginx.conf.bk

Sista stegen, ändra bara lite information i tornets inställningsfil (lägg bara till ditt värdnamn/IP i CLUSTER_HOST_ID) och aktivera/starta Oracle Automation Manager Service med Systemd
[root@OracleAuto ~]# grep -i CLUSTER_HOST_ID /etc/tower/settings.py
CLUSTER_HOST_ID = "OracleAuto"

[root@OracleAuto ~]# systemctl enable --now ol-automation-manager.service

Och voilà! du kan nu börja hantera dina eventuella spelböcker direkt från Oracle Automation Manager Interface
Jag behöver verkligen lära mig mer om Ansible och Automation, så det här kan vara ett bra sätt att börja använda Oracles egen Automation Manager :)
