Hosting a CI/CD platform on Kubernetes is becoming more common among engineers. This approach saves time through automation, ensures consistent deployments, and makes it easier to monitor and manage microservices. However, building container images in Kubernetes clusters involves some technical hurdles that require workarounds. In this article, we’ll explore some ways to build Docker images in a Kubernetes cluster for CI/CD processes.

Application innovation, design, development, quality assurance, and security testing have changed dramatically over the past decade. Engineering teams are leveraging agile development processes, modern cloud platforms, reusable microservices, and extensible APIs, enabling them to shift to more frequent deployments more easily.

In recent years, we’ve witnessed a constant increase in the number of malicious packages showing up in various ecosystems. Generally speaking, the vast majority of these packages are benign, as in, they collect information, but don’t do harm to the infected machine. Once in a while, however, we do encounter a truly malicious package that has a purpose, means, and is production-ready — this is a story about one of them.

While most developers — myself included — primarily write in higher-level languages like Python or JavaScript, sometimes you need to add in native elements to improve performance or other project aspects. Since these native extension invocations are typically written in C or C++, suddenly a project primarily using JavaScript or Python must also account for potential C/C++ transient dependencies.

With dependence on containers growing more every year, developers need the best container security solutions they can find, and those solutions have to integrate seamlessly into existing development workflows. Snyk’s partnership with Sysdig has helped us strengthen our commitment to building tools for container security, and growing those tools to meet the evolving needs of developers. And as a developer-first organization, we truly value feedback that comes right from developers themselves.

Unless you have experience as a Kubernetes operator or administrator, admission controllers may be a new feature for you. These controllers work mostly in the background and many are available as compiled-in plugins, but they can powerfully contribute to a deployment’s security. Admission controllers intercept API requests before they pass to the API server and can prohibit or modify them.
