Almost all software developers and IT administrators are familiar with Kubernetes. Regardless of the particular field in which they work, Kubernetes is either already being utilised or is under consideration.
When asked what Kubernetes is, it is a free and open-source container orchestration solution that simplifies the process of deploying and scaling applications and managing the associated infrastructure. Kubernetes is a tool for controlling software containers in a distributed environment, and provides a great degree of flexibility, automation and potential for growth that surpasses other systems.
Kubernetes, a technology developed by Google and currently managed by the Cloud Native Computing Foundation, is employed by numerous companies around the globe. Several renowned organisations have adopted or are currently leveraging Kubernetes, including Babylon, Booz | Allen | Hamilton, Booking.com, AppDirect, Adidas, Ancestry.com, adform, Bose, box, Buffer, CapitalONe, CERN, Huawei, IBM, ING, The New York Times, NOKIA, Nordstrom, Spotify, Squarespace, Yahoo! Japan, and many more.
Kubernetes is a powerful tool, but it is not suitable for those who are new to the software. It is particularly useful for those with an interest in enterprise resource planning (ERP) software development or on-premise cloud solutions, so it is worth exploring. However, it is important to ensure that the necessary steps have been taken in advance to ensure a successful implementation.
It is clear that Kubernetes does not adhere to the standard software development process nor does the end product it produces. This is mainly because Kubernetes is a complex technology with many moving parts, making it difficult for companies outside of the Fortune 500 to adopt it at a greater rate. Thus, it is understandable why there are a few roadblocks in the way of wider Kubernetes adoption.
If you were curious, let us delve into some of the issues impeding the widespread acceptance of Kubernetes. We shall examine a few of the obstacles currently preventing its adoption.
It’s a mess.
It is clear that Kubernetes is a powerful technology, however, it does come with a significant drawback; it requires a considerable amount of time to become proficient. While it is possible to deploy a Kubernetes cluster in as little as fifteen minutes, this is simply the start of the process. Once the cluster is deployed, it is not uncommon to encounter issues that need to be resolved. Consequently, it is essential to invest the necessary time to study and practice Kubernetes in order to be able to use it effectively.
Once your cluster is up and running, it quickly becomes apparent that while Docker Swarm clusters are highly effective for deploying and scaling individual applications or services, Kubernetes is more focused on the integration of these components to create a much more powerful system. Consequently, the process of deploying these applications and establishing the connections between them is a much more complex endeavour in comparison to Docker.
Despite the difficulty, this was intended. Kubernetes is more complex to comprehend than Docker due to the fact that it is more powerful and has more flexibility. Docker on the other hand makes container deployment and scaling simpler. To make the most of this, it is necessary to understand how all the components are connected. To gain a comprehensive understanding of Kubernetes, it is necessary to have a comprehensive knowledge of a range of technical concepts, such as pods, services and replication controllers.
It is worth noting that there are a number of approaches to implementing Kubernetes. These include k8s, kubectl, kubeadm, minikube, kubernetes-cli, and many more. With so many options available, it can be difficult to decide which one would be the most suitable for your needs.
It’s not impossible, despite how complicated it is. It’s simply a lot harder to implement well compared to other technologies.
Using software and online resources
Kubernetes provides a range of applications and services, and the next challenge is to ensure their availability. This process is straightforward when using Docker, since when deploying an application or service, it will function in virtually an identical manner as if it had been traditionally deployed. For example, to access a website after deploying an NGINX container on a Docker Swarm, all that is necessary is to open a browser and enter the IP address of any node in the Swarm.
Deploying a containerised application on a Kubernetes cluster can be a complicated process. If the IP address scheme of the cluster is 10.20.1.x, but the IP address scheme of the local area network (LAN) is 192.168.1.x, then further steps must be taken to make the application or service available on the 192.168.1.x LAN. To achieve this, it may be necessary to set up an Ingress controller; however, even after doing this, the application or service may not be accessible.
Inadequate graphical user interface
It is important to note that Kubernetes offers an impressive graphical user interface (GUI). This Web UI is a powerful resource for managing a cluster. However, it is necessary to deploy a container to the cluster before being able to access the Web UI. Subsequently, accessing the GUI is only possible from within the cluster – not from a local area network. As such, the Web UI is designed to be accessed from the cluster, and not from a desktop interface on the server.
Despite the fact that the majority of Kubernetes clusters are set up on headless Linux servers, this makes it challenging to use the Web User Interface (UI). Furthermore, many other Graphical User Interface (GUI) solutions have the same issue as the Web UI.
Kubernetes is unfortunately hindered by its reliance on graphical user interfaces (GUIs) to facilitate the deployment and management of containers. This is due to the fact that it cannot be accessed from a local area network (LAN) without undergoing a number of technical obstacles. These obstacles, when combined, make it impossible to have an effective graphical interface to control the applications and services of the system.
It is clear that in order for the Kubernetes developers (or a third party) to make adoption of their system more straightforward, they must provide a simpler way for users to connect to their cluster through a local area network. Without this, the difficulty in adopting Kubernetes is greater than has been previously acknowledged, as administrative work is far more challenging without a user friendly, point-and-click interface that can be easily deployed.
Jumping on the Kubernetes Bandwagon
If you are seriously considering transitioning to Kubernetes, it is important to take your time to fully understand the intricacies of the system before commencing. Despite this, there will still be hurdles to overcome and it may not be a straightforward process. Nevertheless, Kubernetes can offer unprecedented opportunities for the deployment and scaling of applications and services.
It is thus likely that the time and energy spent on solving the problems will be worthwhile.
