It has come to my attention that Kubernetes is shifting away from Docker usage. This has been of particular interest to me, particularly due to the increased popularity of Docker and Kubernetes among businesses, as well as the rise in demand for DevOps and backend development roles in recent years.
Where Do Docker and Kubernetes Stand Right Now?
It has been announced on the Kubernetes blog that Docker as an underlying runtime is being deprecated in favor of runtimes that use the Container Runtime Interface (CRI) developed for Kubernetes. However, images built using Docker will continue to work in any cluster, regardless of the runtime.
I have respect for those who are skilled in the usage of Kubernetes, however I am concerned about the implications for your future in IT. What steps should you take now to ensure that you are at the leading edge of the latest technology and guarantee your success in the business in the next three years or more? Additionally, what indications should you look out for when making staffing decisions for your organisation?
If your organization has been utilizing Docker and Kubernetes for containers, then your team already has a good understanding of containers, and familiarizing themselves with Containerd or CRI-O will be a straightforward task of refreshing their existing knowledge.
If you are looking to recruit for your team, it is beneficial to consider candidates with experience of Kubernetes and Docker. Even with the most experienced DevOps professionals, it is recommended that they upgrade their skillset to include Containerd, as it is an open source solution.
It is clear that having knowledge and experience in Docker and Kubernetes will be a great asset, regardless of whether you choose to use Containerd or CRI-O. Although Docker will remain a key player in the business world, it is more likely to be of greater value in DevOps than in backend development. Even if Docker loses some popularity when it comes to Kubernetes-based development teams, your skills will be easily transferable.
Kubernetes’ website states that the Docker installation used in development is not linked with the Docker runtime within the Kubernetes cluster. Nevertheless, Docker can still be advantageous for development purposes.
If you have not been taking advantage of Kubernetes, there is no need to be concerned. However, if you have, you can expect some modifications. The IT sector is renowned for its rapid advancement, but this is simply one of the risks that come with the job.
The intelligent are like water in a pitcher; they shape themselves to fit whatever conditions they’re put in.
Confucian Saying
Docker is being phased out on Kubernetes, but why?
The primary reason for this decision is that Kubernetes’ security could be compromised due to Docker’s implementation of an unnecessary user interface for Kubernetes.
After careful consideration, the Kubernetes team has determined that continuing to support Docker would not be advantageous for the Kubernetes ecosystem.
Should you Worry About the Future of Your Company?
Rest assured, everything is alright. Despite the extraordinary events of 2023, the world will not come to an end tomorrow. Docker remains as a viable solution for many applications. To clarify, Kubernetes is still compatible with Docker containers, however, going forward, Docker will no longer be supported as a container runtime. You may choose to stay with the previous version and continue using Docker and Kubernetes, however, this is not recommended as it may result in your software being out of date and not receiving any support from the Kubernetes community. Therefore, we strongly advise against this practice.
Our DevOps consultants have confirmed that upgrading to the next version, which necessitates switching to either Containerd or CRI-O, should not be overly difficult. We recommend that you speak with your development team and allocate sufficient time for them to analyze the implications for your codebase. They will be in a position to provide advice on how to move forward.
Trust in your team; if you don’t feel that you can rely on them, it might be best to look elsewhere. At Works, we are committed to helping you create the perfect team as quickly as possible. We have supported businesses in recruiting experienced remote developers in as little as two weeks. Let us help you expand your IT department.
What Does Kubernetes Deprecating Docker Mean for Your Professional Career?
It suggests that having experience working with Containerd or CRI-O could have made your profile more attractive to potential employers, as you would be able to contribute to new projects or improve existing ones.
If you have experience working with Kubernetes and Docker, it would be beneficial for your career to become familiar with Containerd or CRI-O and add them to your skillset on LinkedIn. This will aid employers in recognizing your capabilities.
Prepare a brief presentation outlining the implications of this shift for your team; your manager will be appreciative of the effort and it may even have a positive effect on your next salary review. Companies are highly appreciative of proactive employees.
