As shortages of consumer goods and rising prices caused by bottlenecks in international supply networks have become more common, the global supply chain and its vulnerabilities have been top of mind for many. For developers, several high-profile software security exploits have recently underscored the risks inherent in a similar type of supplier network: the software supply chain.

Security is a never-ending battle on the web. You can have a server up in just a few minutes, and the next minute, someone is already trying to hack into it. These attacks could be automated using malicious bots or launched manually. Websites can be targeted by a malicious user trying to compromise your web presence or data. Cross-site scripting (XSS) is just one type of attack your site may be vulnerable to.

CI/CD systems follow a multi-tiered environments pattern: development, testing, staging, and production release are all part of this process. Each setting in this cycle could have a variety of set ups and configurations. As a result, having to set up separate configurations for different environments could be inconvenient and burdensome. In this tutorial, we will take a look at what Docker is and how it has freed developers from set-up problems and port clashes.
