SESSION WITH EXPERTS

This blog is totally about, what I have learnt from webinar which I had as a ARTH LEARNER with two best industry expert Mr. Sreejith Anujan & Mr. Arun Eapen of RED HAT.

?

The Session was totally on the Automation using Ansible- Demo (Practical Implementation).

So, what I learnt from the Webinar:

1. AUTOMATION:- Automation is the application of technology, programs, robotics or processes to achieve outcomes with minimal human input. Automation is the creation of technology and its application in order to control and monitor the production and delivery of various goods and services. It performs tasks that were previously performed by humans.
2. ANSIBLE TOWER:- Ansible Tower is a web-based interface for managing Ansible. One of the top items in Ansible users’ wishlists was an easy-to-use UI for managing quick deployments and monitoring one’s configurations. Ansible management came up with Ansible Tower in response.  It’s designed to be the hub for all of your automation tasks. Ansible Tower gives you role-based access control, including control over the use of securely stored credentials for SSH and other services.

• In Ansible architecture If our controller node goes down then our Automation will also losses. That's the one point or reason where the concept of Ansible Tower comes out. " It gives us a Clustering feature by which we can have multiple Ansible Tower deployed and they will share a common database which is POSTGRESQL and using this we will having redundancy for our Automation and scale up our automation even if our Controller Node goes down.

3. ANSIBLE TOWER CAN BE USED FOR:-

• PROVISIONING
• CONFIGURATION
• ORCHESTRATION
• DEPLOYMENT

ETC.

4. ORCHESTRATION:- It allows us to define your infrastructure once and use it wherever and however we need. Once we’ve got Playbooks that describe our multi-node production infrastructure, we can then use the same orchestration to deploy it on our laptop or in our private OpenStack cloud for testing.

5. JOB TEMPLATE:- A job template is a definition and set of parameters for running an Ansible job. Job templates are useful to execute the same job many times. Job templates also encourage the reuse of Ansible playbook content and collaboration between teams.

6. We can use the VERBOSITY in Ansible Tower like Normal, Verbose, More Verbose, Debug, Connection Debug.

7. CONTINUOUS INTEGRATION & DEPLOYMENT.

8. Ansible tower will also connect to AWS Cloud via it's API. And Tower will also manage the controller node behind. We just only have to update our Inventory File of Ansible.

9. AWX:- It is the community version of Ansible Tower.

10. CHATOPS:- It is a model where people, tools, process and automation are connected in a transparent flow.

11. In Ansible, we used to imort multiple playbooks or include multiple hosts inside the main playbook to run and configure the Requirements. But in Ansible Tower we just have to create a Workflow.

12. ANSIBLE TOWER HAVING MULTIPLE TYPES OF NOTIFICATION TITLES:-

• EMAIL
• SLACK
• GRAFANA

etc.

13. ANSIBLE COLLECTIONS:- Distributed format for Ansible content that can include playbooks, roles, modules, and plugins.

THAT'S ALL.
