I also run a Facebook group named as “DevOps Practices group” along with a Whatsapp group. You can send a request to me to add you, if your role is relevant as per the description given on that FB page. [https://www.facebook.com/groups/1911594275816833/about/]
If you are really involved in implementing the DevOps practices the discussion points will certainly help you to move forward with expected velocity.
I invite all of my blog readers to self filter yourself as per the eligibility while sending a request to me. Thanks.

This is a recorded video for Minikube installation in Ubuntu VM.
If you are using Ubuntu VM on VMWARE or Oracle Virtual Box or any other VM software, then only this exercise is useful to practice for Kubectl installation with Minikube.
Please note Minikube is a CE edition of Kubernetes.

How to change your linux virtual machines hostname and connect with ssh?
In this blog/video, I would like to demonstrate
the following by connecting hostnames with ssh:
Sometimes, we need to have hostnames differently.
When you use deployments using Ansible, etc. SCM tools
we can connect to the hostnames directly.
Now let us analyze and use the exercise as below:
By default we can find the hostname with;
$ ls -l /proc/sys/kernel/hostname
$ cat /proc/sys/kernel/hostname
We can also look into the details by using;
To change the new name use;
$hostnamectl set-hostname ‘ans-dbserver’
Step1: Checking the current hostname.
Step2: Checking the host details in hostnamectl.
Step3: Changing the hostname.
Step4: Looking for new host details.
Step5: Reboot the machine and check its
connection with new hostname.
Step6: Now, let us try to connect to other machines
with ssh connectivity.
Step7: Making sure the renamed machine host is
being accessed by other machines also through ping.
Step8: Install openssh-server to connect through ssh in the newly named machine.
Step9: Connect through ssh from master machine to current hosts.
The attached video has the demonstration for all the above steps on Linux Virtual machines. Proved with a connectivity through ssh.
For SSH configuration please visit my blog, it has the demonstrated video also:
