This post is courtesy of Markus Ziller, Solutions Architect. Today, git is a de facto standard for version control in modern software engineering. The workflows enabled by git’s branching capabilities are a major reason for this. However, with git’s distributed nature, it can be difficult to reliably remove changes that have been committed from all copies of the repository. This is problematic when secrets such as API keys have been accidentally committed into version control. The longer it takes to identify and remove secrets from git, the more likely that the secret has been checked out by another user. This post shows a solution thatRead More →

A Practical Guide To HashiCorp Consul — Part 2 This is part 2 of 2 part series on A Practical Guide to HashiCorp Consul. The previous part was primarily focused on understanding the problems that Consul solves and how it solves them. This part is focused on a practical application of Consul in a real-life example. Let’s get started. With most of the theory covered in the previous part, let’s move on to Consul’s practical example. What are we Building? We are going to build a Django Web Application that stores its persistent data in MongoDB. We will containerize both of them using Docker. Build and run them usingRead More →

A Practical Guide to HashiCorp Consul Part 1 This is part 1 of 2 part series on A Practical Guide to HashiCorp Consul. This part is primarily focused on understanding the problems that Consul solves and how it solves them. The second part is more focused on a practical application of Consul in a real-life example and will be published next week. Let’s get started. How about setting up discoverable, configurable, and secure service mesh using a single tool? What if we tell you this tool is platform-agnostic and cloud-ready? And comes as a single binary download. All this is true. The tool we are talking aboutRead More →

Getting Started With Kubernetes Operators (Ansible Based) — Part 2 Introduction In the first part of this blog series, getting started with Kubernetes operators (Helm based), we learned the basics of operators and build a Helm based operator. In this blog post, we will try out an Ansible-based operator. Ansible is a very popular tool used by organizations across the globe for configuration management, deployment, and automation of other operational tasks, this makes Ansible an ideal tool to build operators as with operators also we intend to eliminate/minimize the manual interventions required while running/managing our applications on Kubernetes. Ansible based operators allow us to use Ansible playbooks andRead More →

Getting Started With Kubernetes Operators (Helm Based) — Part 1 Introduction The concept of operators was introduced by CoreOs in the last quarter of 2016 and post the introduction of operator framework last year, operators are rapidly becoming the standard way of managing applications on Kubernetes especially the ones which are stateful in nature. In this blog post, we will learn what an operator is. Why they are needed and what problems do they solve. We will also create a helm based operator as an example. This is the first part of our Kubernetes Operator Series. In the second part, getting started with Kubernetes operators (Ansible based), and theRead More →

Due to recent refactoring, I figured out that I need to move some Terraform state items from one S3 path to another. And then to merge configurations with other stuff at the destination directory. Terraform can move state items around, but this feature doesn’t work with remote states. Here is one way of doing it. Example Use Case First, let’s consider the following situation, this is configuration directory tree output: . ├── db │   └── test │   ├── main.tf (s3 key: aws/db/test/terraform.tfstate) │   └── rds.tf ├── test │   ├── main.tf (s3 key: aws/test/terraform.tfstate) │   ├── sqs.tf You want to merge db/test state items into aws/test/terraform.tfstateRead More →
