How to fix error “[SSL: CERTIFICATE_ VERIFY_FAILED] certificate verify failed” (_ssl.c:727)

If you’re encountering the “SSL: CERTIFICATE_VERIFY_FAILED” error while working with Python’s requests library, don’t worry. Typically, this issue occurs because you need to update your CA certificates, set up custom trust paths, or avoid development shortcuts that can lead to security vulnerabilities.

Understanding SSLCertVerificationError

While collaborating on a hybrid cloud project with a client in the banking sector, we encountered a problem:

Fatal error: SSL validation failed for https://bucket_name.s3.ap-south-1.amazonaws.com/file_name  “[SSL: CERTIFICATE_ VERIFY_FAILED] certificate verify failed” (_ssl.c:727) Continue reading “How to fix error “[SSL: CERTIFICATE_ VERIFY_FAILED] certificate verify failed” (_ssl.c:727)”

Learn How to Control Consul Resources Using ACL

When we talk about service mesh, consul is one of the open-source tools which is widely used as a service discovery for multiple ephemeral or non-ephemeral resources. There are multiple consuls [service mesh] alternatives which are used as a service discovery but we won’t be discussing service discovery & alternative comparisons here.

If we talk about consul, it is not only used as a service mesh but also provides multiple options and features other than a service mesh. Yes, you heard it right, this lad can do lots of things that we didn’t know or haven’t explored yet.

Let’s talk about some of the options or features provided by the consul and further, we will discuss some of the aspects and impact of things provided by the consul.

Introducing Kubernetes Vault Web-hook

Initially, we had the DevOps framework in which Development and Operation team collaborated to create an “Agile” ecosystem. But nowadays a lot of people are talking about the “DevSecOps” realm in which people do not treat security as an afterthought instead of that people are inculcating security in their development and operation practices.

JQ – The JSON Processor

Tired of filtering semi-structured data from command output? What if I tell you can easily filter from structured or unstructured document data. Yes, you heard it right, we are talking about JSON [JavaScript Object Notation]. JSON is a text-based data format programming language that is used to serialize and transmitting structured or unstructured data or we can say semi-structured data over a network connection.

But Why Json ?

We generally think JSON means data provided general output from any API. But, if we talk about any technology, JSON is a very common programming language or we can say format, which is used as the output format of any resource. While using DevOps tools like Docker, Ansible, or any other tool, we generally get the output in JSON format when we use any output command like Docker inspect or Ansible facts gather.

Proc File System in Linux – An Overview

The Proc File System (procfs) in Linux is an innovative, virtual file system located in memory. It serves as a live interface to the kernel’s internal data structures. Instead of keeping data on disk, “files” within procfs are created in real time as they are accessed, providing up-to-date information about the system’s processes, hardware, and overall configuration.

Proc File System in Linux – Complete View

The proc file system, or procfs, is a dynamic virtual file system that becomes active when the system boots and disappears during shutdown. It serves as a valuable resource, providing information about currently running processes, and as a hub for controlling and relaying information to the kernel. Additionally, the proc file system facilitates communication between kernel space and user space.

I’d like to share an interesting finding with you today. Perhaps, many of you must be already familiar with it but being a newbie, it really intrigued me. Continue reading “Proc File System in Linux – An Overview”
