Ansible: Handling Multiple Hosts via SSH
PROBLEM To run Ansible playbook in multiple hosts via SSH. SOLUTION Configuring SSH environment Ensure SSH keypair exists on the current machine (ex: ~/.ssh/id_rsa for private key and ~/.ssh/id_rsa.pub for public key).

Git: Querying Tags Without Cloning the Repository
PROBLEM A typical way to get a list of tags from a repository is to clone it before running git tag:- versionsort.suffix=- ensures 1.0.0-XXXXXX comes after 1.0.0.

About Author
This author has 20+ years of experience in software engineering and cloud engineering. In an industry where knowledge becomes obsolete in the next three months, he learns anything that crosses his path with no mercy. He codes Java while drinking Espresso and writes Spock specifications while listening to Groovy beats. He masters Google Cloud Platform just like he masters the art of predicting the movement of dark clouds over his backyard, where 60% of the time, he is right every time.
This author suffers from the Dunning-Kruger effect, where he overestimates his competence and underestimates his ignorance. Technology buzzwords never scare him, for he does not know what to be afraid of in the first place. GCP, GCS, GCR, GKE, GWT, JWT… they all sound the same to him. This author is a jack of all trades but a master of none. He writes like he knows all the answers, yet he googles for better solutions from elsewhere. He fakes it until he makes it, and if he doesn’t, that’s okay because he has the attention span of a squirrel.
By now, you should know this author is full of shit, and he apologizes in advance if you are trying to solve your company’s real problems with his shitty solutions.
