Ansible Ansible: Date and Time Anyone who works with Ansible knows how to access the current date and time. But have you ever dealt with something a bit more advanced? There are a few tips you may find helpful.
Ansible Ansible: Dynamic Inventory I know that Ansible could use as inventory virtually anything, including scripts. However, all inventories on my day job are static, and we keep them in a source repository, and until now, I haven't had a chance to create or use one.
Ansible Ansible: Markdown Reports The previous post [https://chronicler.tech/ansible-simple-reports] promised a simple reporting solution and two potential possibilities. Now it's time to go through the solution that would help you with report
Ansible Ansible: Format e-mail body. The whole automation idea is to minimize or exclude humans from the process. However, you need to notify users and sometimes you should do it in style.
Ansible Ansible: Simple Reports Any IT system, bigger than a chihuahua, ought to produce reports. It does not matter how they look, but it should generate and share information that humans can read.
Ansible Ansible, YAML, and JSON Ansible is very flexible with data types, and easily transforms primitives and even JSON strings, but from time to time you need to process and transform something a bit more complex than String to Boolean conversions.
Ansible Ansible: Iterations Iterations in Ansible are not first-class citizens. The language allows you a single task loop with one nested iteration. Anything more sophisticated than that should be implemented as a separate module. Again, the include_tasks command gives us a helping hand.
Ansible Ansible: Selections Let's discuss selections in Ansible: if-then-else and case/switch operators. Ansible offers conditional execution for single tasks, blocks, and task imports. In addition, it allows effectively simulate if-then selection.
Ansible Ansible: Subroutines The second post in the Ansible: Control Structures [https://chronicler.tech/ansible-control-structures/] series describes using Ansible core components to emulate subroutines - procedures and "packages." The whole paradigm of Ansible
Ansible Ansible: Control Structures Red Hat Ansible is a powerful and easy-to-learn automation product. Simplicity is one of the basic principles of the language. Yet, any task a titbit more complex than installing and starting an HTTPD server requires good old procedural control flows.
Ansible Ansible Variables: a Rookie Mistake The mistake I made could be excused for Java Developer, but not for a guy who spends days with Ansible. The root cause is the different variable visibility model. Red Hat Ansible does not appreciate role or play boundaries and dynamically evaluates a variable value for each impacted host.
Git Automate Housekeeping For one who does automation for living, it's okay to be a bit lazy. So let's talk about how I keep my local git repositories in order with minimal effort.
Ansible Ansible and Git Submodules Let's discuss a problem I faced, moving from Ansible to the Ansible Tower. The problem is how to maintain multiple inventories scattered all over new projects effectively.
Ansible Ansible: Conditional Playbooks I have praised Ansible tags all about the previous post. Unfortunately, tags don't go along with Ansible Tower's complex workflows. Let me guide you through the playbook transformation we've done. The answer to this challenge is extra variables.
Ansible Ansible: the Power of Tags Let's talk about why you should use tags in your Ansible playbooks. For starters, I'll lecture you a bit about tags in the Ansible language, and then show you how we use them in a real-life scenario.
Ansible Ansible Tower: Dynamic Usernames The slow drift toward the Red Hat Ansible Tower uncovers more and more compatibility issues, so I have to go back and revisit some decisions and make sure that the same code would fit both worlds.
Ansible Ansible: Consume SQL*Plus Output A simple way to consume Oracle Database data in Ansible playbooks without extensive Python or PL/SQL coding or 3rd party modules.
Ansible Automating Oracle Forms environment files configuration Automating everything many times comes to a halt once you discover that specific applications or platforms do not support changes to be done using a command-line interface. One such application
Ansible Ansible: dynamic usernames Ansible uses OS username to authenticate against targets. When you need to run commands as a different user, you have multiple options: privilege escalation, set a remote username, and dynamic definition in inventory.
Git What I ignore in Ansible projects Keep your repository neat and clean is a mandatory repository requirement, same as readable documentation and a good code, preferably useful. So, one of the first things I do in a new project is a .gitignore file.
Ansible How to run Ansible playbooks à-la Tower Our Red Hat Ansible projects drift to the Ansible Tower. I found that it much faster to do quick fixes and debug playbooks from the server rather than go through the full chain VSCode -> Git -> Tower. Well, to be productive, I automated the automation.
Ansible Using Ansible to connect to Oracle Dynamic Monitoring Service (DMS) The Oracle Dynamic Monitoring Service (DMS) enables Oracle Fusion Middleware components to provide administration tools, such as Oracle Enterprise Manager, with data regarding the component's performance, state and on-going behaviour.
Ansible Ansible host in different groups and group_vars When you try to organize your variables in Ansible, storing them in your inventory will help you to keep all your environments metadata in one place. Splitting host and group
Ansible Unsafe writes - why you need it. As a former Oracle DBA, I'm totally against anything marked as "unsafe." Today I have learned why RedHat Ansible [https://www.ansible.com] has unsafe_writes clause for some commands.
Ansible I want to be a ... I'm working on the small project which touches multiple cloud-based hosts across multiple providers. And this is a good chance to refresh your knowledge on how to handle various connections
