The following list contains all posts I wrote about Ansible in chronological order
Using Ansible to resize the root LV on Oracle Linux 9 in OCI
While preparing an upcoming talk at a community event I worked on some Terraform code I recycled. In a nutshell, I’m creating a virtual machine in Oracle Cloud Infrastructure using Oracle Linux 9. I’m fully intending to run Oracle Database 19.28.0 on that VM later. Rather than sticking with the default boot volume size I…
Vagrant Ansible Provisioner: working with the Ansible Inventory – addendum
Recently I wrote a post about one of my dream combinations, Ansible and Vagrant. After hitting the publish button I noticed that there might be a need for a part II – passing complex data types such as lists and dicts to Ansible via a Vagrantfile. I wrote a similar post for when you are…
Ansible tips’n’tricks: gather facts in an ad-hoc fashion
There are times when I really need to get some ansible_facts from a host to work out details about, say the network card, storage, or Linux Distribution to continue coding. And I don’t want to/have the patience to run add a debug step in my Ansible playbook either :) Thankfully Ansible has just the right tool for…
Vagrant Ansible Provisioner: working with the Ansible Inventory
Vagrant and Ansible are a great match: using Vagrant it’s very easy to work with virtual machines. Creating, updating, and removing VMs is just a short command away. Vagrant provides various provisioners to configure the VM, and Ansible is one of these. This article covers the ansible provisioner as opposed to ansible_local. Earlier articles I…
Vagrant: always provision virtual machines
Since Spectre and Meltdown (2 infamous side channel attack vectors on CPUs) have become public I thought about better, more secure ways to browse the web. When I read that a commercial vendor for operating systems created a solution where a browser is started in a disposable sandbox that gets discarded when you exit the…
Configuring a VM using Ansible via the OCI Bastion Service
In my previous post I wrote about the creation of a Bastion Service using Terraform. As I’m incredibly lazy I prefer to configure the system pointed at by my Bastion Session with a configuration management tool. If you followed my blog for a bit you might suspect that I’ll use Ansible for that purpose. Of…
Ansible tips’n’tricks: configuring the Ansible Dynamic Inventory for OCI – Oracle Linux 7
I have previously written about the configuration of the Ansible Dynamic Inventory for OCI. The aforementioned article focused on Debian, and I promised an update for Oracle Linux 7. You are reading it now. The biggest difference between the older post and this one is the ability to use YUM in Oracle Linux 7. Rather…
Installing Ansible on Oracle Linux 8 for test and development use
I have previously written about installing Ansible on Oracle Linux 7 for non-production use. A similar approach can be taken to install Ansible on Oracle Linux 8. This is a quick post to show you how I did that in my Vagrant (lab) VM. As it is the case with Oracle Linux 7, the Extra…
Ansible tips’n’tricks: run select parts of a playbook using tags
I have recently re-discovered an Ansible feature I haven’t used in a while: tagging. Ansible allows you to define tags at various places of your playbook. On its own that wouldn’t be terribly useful, except that you can pass tags to ansible-playbook causing the interpreter to selectively run tasks tagged appropriately. My example uses Ansible…
Ansible tips’n’tricks: using the OCI Dynamic Inventory Plugin in playbooks
After having covered how to configure the Ansible Dynamic Inventory Plugin for Oracle Cloud Infrastructure (OCI) in the previous posts now it’s time to get it to work with my simple-app cloud application. Before I go into more detail, I’d like to add the usual caveat first. Caveat As I said in the previous post,…
