Run Azure DevOps Private Agents in Kubernetes Clusters

Since in last post, we discussed on how to run Azure Pipelines agents as docker containers and configure them accordingly, the next step would be to run them on the Kubernetes platform. This kubernetes cluster can be on-premise and/or cloud and could be self managed or managed by the cloud service provider itself.

One of the reasons you may want to run them on Kubernetes is because you want better utilization of your kubernetes cluster. Another reason might be to leverage your existing knowledge of the kubernetes platform and work on it. Another reason would be to not use Microsoft hosted agents, as by default you would get only 1800 minutes of agent time to utilize, for free accounts.

Running Azure DevOps private agents as docker containers

To run the build or deployment jobs in Azure DevOps or Azure Pipelines (formerly known as TFS and VSTS respectively), an agent is required. Microsoft provides the different types of the agents and they are hosted and managed by Microsoft only. However, it is advisable to host your own private agent for various reasons other than the cost. Microsoft provides the facility of installing agent on various OS’es like Windows, Linux, Mac OS etc. They have done a good job in terms of documentation, however you still need to perform few steps in order to set it up correctly.

Use OpenSSL to work with SSL Certificates, CSR and Private Keys

OpenSSL is a robust, commercial-grade, and full-featured toolkit on the Linux that can be used for a large variety of tasks related to Transport Layer Security (TLS) and Secure Sockets Layer (SSL) protocols. It is also a general purpose cryptography library. It is licensed under an Apache-style license, which basically means that you are free to get and use it for commercial and non-commercial purposes subject to some simple license conditions.

It is already installed out of the box on the most linux distributions or available in the trusted package repositories. OpenSSL has been kind of standard in the open source domain to work with SSL and TLS protocols. If for some reason, it is not already installed, you can install it by using your distribution specific commands. Continue reading “Use OpenSSL to work with SSL Certificates, CSR and Private Keys”

Install Subversion and Create a new source code repository

Subversion needs no introduction to the world of source code management. Subversion is a modern, network-aware version control system. It is an open source project distributed under Apache license by Apache foundation. The open source community has used Subversion widely: for example in projects such as Apache Software Foundation, Free Pascal, FreeBSD, GCC and SourceForge. CodePlex offers access to Subversion as well as to other types of clients. There are other large enterprises where Subversion is the first choice for version control purposes.

Subversion was created by CollabNet Inc. in 2000, and is now a top-level Apache project being built and used by a global community of contributors.

In this blog post, we’ll learn how to download and install subversion and create a new source code repository for us.
