What Does Kubernetes’ Plan to Deprecate Docker Mean for Your DevOps Career?

Recently, I stumbled upon the news that Kubernetes is transitioning away from Docker. I found this especially intriguing as Docker and Kubernetes are growing in popularity within the business landscape, and the demand for DevOps and backend development positions has experienced a significant push in the past few years.

The Current Standpoint of Docker and Kubernetes

According to a blog post on Kubernetes, Docker will soon be replaced by runtimes incorporating the Container Runtime Interface (CRI) specifically designed for Kubernetes. Nonetheless, Docker-built images will remain functional in any cluster, irrespective of the runtime in use.

While I hold deep admiration for those proficient in utilising Kubernetes, I have apprehensions regarding how it may impact your future in IT. Hence, what measures could you adopt presently to stay abreast with the latest technology and secure your business success for at least the next three years? Moreover, what signs should you consider when making staffing choices for your organisation?

In the event that your company has been using Docker and Kubernetes for containers, your team must possess a decent comprehension of containers. Hence, acquainting themselves with Containerd or CRI-O will be a simple exercise in recapping their current expertise.

If your goal is to hire candidates for your team, it is advantageous to look for those with prior experience of Kubernetes and Docker. Additionally, even the most proficient DevOps professionals would benefit from upgrading their expertise to encompass Containerd – an open source solution.

Undoubtedly, possessing a deep understanding and experience of Docker and Kubernetes will be extremely valuable, regardless of whether you decide to employ Containerd or CRI-O. Despite Docker retaining its importance in the business realm, it is expected to be more advantageous in DevOps than in backend development. Furthermore, even if Docker experiences a drop in popularity among teams working with Kubernetes, your skills will remain easily transferable.

The Kubernetes website clarifies that the Docker installation employed in development is not associated with the Docker runtime within the Kubernetes cluster. In spite of this, Docker can still prove useful for development intents.

If you have not been utilizing Kubernetes, there is no need for alarm. However, if you have, certain modifications can be expected. The IT industry is widely acknowledged for its rapid progress, but this is just one of the perils that come with the profession.

The wise are akin to water in a vessel; they mould themselves to suit any setting they find themselves in.

Confucian Saying

What is the Reason behind the Phasing Out of Docker on Kubernetes?

The key factor behind this judgement is that Docker’s superfluous user interface for Kubernetes could expose vulnerabilities within the security of Kubernetes.

Upon thorough evaluation, the Kubernetes team has concluded that upholding support for Docker would not benefit the Kubernetes ecosystem.

Is There Cause for Concern Regarding the Future of Your Organisation?

You can be reassured that everything is fine. In spite of the unprecedented events of 2023, the end of the world is not upon us. Docker continues to be a practical solution for numerous applications. To clarify, Kubernetes remains compatible with Docker containers, yet in the future, Docker will no longer be supported as a container runtime. While you may opt to stick with the previous version and persist in using Docker and Kubernetes, we do not recommend this as it could lead to your software becoming outdated and unsupported by the Kubernetes community. Hence, this practice is strongly discouraged.

Our DevOps experts have verified that upgrading to the next version, requiring a shift to either Containerd or CRI-O, should not be an unduly taxing task. It is recommended that you consult your development team and allot adequate time for them to evaluate the ramifications for your codebase. They’ll be equipped to offer guidance on how best to proceed.

Have faith in your team; if you feel that they’re not dependable, it may be worthwhile to seek assistance elsewhere.

What Implications Does Kubernetes’ Deprecation of Docker Have on Your Professional Career?

This implies that possessing expertise in Containerd or CRI-O could have bolstered your profile’s appeal to prospective employers, as you’d be able to make valuable contributions to new projects or enhance existing ones.

If you possess experience working with Kubernetes and Docker, it would be advantageous for your professional trajectory to acquire proficiency in Containerd or CRI-O and include them in your LinkedIn skillset. This can assist employers in discerning your aptitude.

Formulate a concise presentation detailing the consequences of this transition for your team; your manager will value the initiative and it could even enhance your prospects during your forthcoming salary review. Businesses place great importance on proactive staff members.
