Introducing OpsTree Tomcat Image

Docker is a platform for developers and sysadmins to develop, deploy, and run applications with containers. And, as we all know Docker image is a read-only template that contains a set of instructions for creating a container that wraps up the software and its dependencies into a standardized unit for software development to run on the Docker platform.

In this post, we are going to step through describing some of the best practices and common pitfalls we encountered while developing our first Dockerfile for Tomcat.

Provisioning Infra and Deployments In AWS : Using Packer, Terraform and Jenkins

Why DevOps Rides on Immutable Infrastructure? The acceptance of “immutable infrastructure” has emerged as a viable way to improve DevOps processes and culture. By introducing standardisation in application deployment and management, the immutable infrastructure helps, among other things, to foster a better collaborative environment among developers, operations, and other stakeholders.

Let’s discuss a bit about Immutable Infra and the benefits which it brings to the table. Once we have a better understanding of it, we’ll really start to see the use case in our Deployments Model.

Introduction to Prometheus Monitoring

Our Team hosted a Workshop on Prometheus which was very insightful and made absolute sense in terms of the Principles and the application part. The audience strength was pretty amazing, besides this, we also received many queries from the people who couldn’t join because of the Virtual Meet Limit. So, we shared the recording and the slides on social platforms. Here we try to share a glimpse of the workshop while keeping the same essence.

Docker BuildKit : Faster Builds, Mounts and Features

It was like any other day working on micro-services project, running on Docker environment. In general, we’ve had worked on making our Image Builds more efficient, secure, and faster following basic aspects that significantly affect building and working with Docker.

Understanding Docker layers and structuring the Dockerfile to maximize their efficiency.
Reducing the weight of the Docker image, by being specific about our Base Image Tags which comes up with minimal packages.
Bringing the multi-stage builds concept, etc.

Create Your First Helm Chart (Part 03)

Bonjour! So we’ve had our minikube cluster up and running and tried setting up MySQL application onto our cluster using publicly available Helm Charts in our previous blog. In case, you haven’t, I suggest you go through the link before reading this blog.

This guide walks us through the process of creating our first-ever chart, explaining what goes inside these packages and the tools we use to develop them. By the end of it we should have an understanding of the advantages of using and creating our Helm Charts to deliver our own applications to the K8s cluster.
