I love the idea of smart inventories, I want a large dynamic inventory and then create small subset inventories based on filters to pass onto my other groups. However; There is a huge issue with the smart inventory that it doesn’t present the group information down to them. So if my DBA team has Dev, QA and Prod environments I would need to create 3 inventories for them DB-Dev, DB-QA and DB-Prod instead of being able to just create one DB group and let them set there job template based on a limit to the environment.Continue reading “Ansible Tower Smarter inventories.”
Tower 3.3 introduced the ability to have multiple versions of Ansible availble, this can be really useful if we have custom python packages needed with dependencies we dont want to upgrade, or we want a specific version of Ansible being run to combat anything deprecated.Continue reading “Set custom virtual environments and Ansible versions in Tower”
In this part we are going to setup Zabbix to detect when a new instance doesn’t have the zabbix agent installed and running to inform our Ansible Tower sever to run the job template to install and configure it.Continue reading “Auto Remediation with Zabbix and Ansible Tower Part 2”
1.) Automatically detect new systems and logically add them to a group
2.) If no Agent is found to be running, then to have Ansible Tower run a job to set it up
3.) Create a collection of playbooks that can be used for auto remediationContinue reading “Auto Remediation with Zabbix and Ansible Tower Part 1”
We want to be able to add a custom dynamic inventory into Ansible Tower, I am going to do this for Service Now but the following method can be used with any.
From the previous 2 parts we have set up Satellite and created our Ansible Playbooks, now we want to put it all together on Tower by creating the Job Templates and Workflows to make this happen.
In Part one we went over the setup of Satellite and Katello-cvmanager to perform the publish and promote in Satellite.
Now we want to create the playbooks that Ansible Tower with use in order to patch the servers and then setup the next lifecycle environment.
You want to create these playbooks, You can skip this section and grab them from my github repo HERE but as always understand what is being done before you just run them.
When it comes to Satellite the flow to patch our life cycle environments feels like a very manual process, after our sync plan completes, I need to publish a new version and then promote this through my environments ( Dev, QA, Prod etc ) What I want is this to be fairly hands off and have it done in the background automatically for me. And so let’s go over the steps needed to achieve this. Continue reading “Auto Patch schedule with Satellite 6.3 and Ansible Tower Part 1”
I have come up many times where people request to be able to create AD DNS A Records or CNames for Linux Servers that are not going to be joined to the domain, I will go through how we can use Ansible Tower to do this for us. This is very similar to the AD Computer object however we also need to get the IP address as an extra variable for an A Record.
I often get asked to setup CloudForms to create AD Computer objects, this will show how to do this with Ansible Tower, the interesting issue we face is CloudForms by default sends the vm name as the limit field but for this we want to run the playbook on a set host and pass the vm name as a variable.
