Here, I demonstrated how #kubernetes can be #installed using #ansible.
This is a raw version. So you may fast forward some of the steps.
I would like to thanks University of Tartu HPC Center (https://www.youtube.com/channel/UCi_viPyHPL_rytr_bwBk55A) for the computing resources.

Ansible

Ansible, ansible delay, Ansible inventory, Ansible-playbook, YAML, YML

In the previous post, we have seen how to generate multiple files using with_sequence and loop features.
Here, we will introduce the delay functionality in the loop feature. This will give a pause after every iteration. So, each file will be created at specific time interval. The official document on loop control can be found here. Download the .yml file directly if you don’t want to go through the discussion.

Ansible, Serverless Computing

Ansible, Ansible-playbook, YAML

Loop and with_sequence allows the commands or the instructions to be executed iteratively. However, I find the syntax bit different from other programming language. Probably this is due to YAML structure. Anyways, lets see few examples and see how to use loop and with_sequence. You can find the official documentation on loop here and on with_sequence here. The list of examples are as follows:

- Generate empty file from a list (using with_items) (.yml file)
- Generate empty file from a list (using loop)(.yml file)
- Generate empty files with pattern (.yml file)

Ansible, Serverless Computing, Ubuntu

Ansible, Ansible-playbook, Ping, Playbook, remote access, YAML

Two ways to test the connection with remote servers.

One is to write the playbook and execute
Other is directly passing the ping command as an argument to ansible command
