Top Practices for Working with Kubernetes

Kubernetes is an open-source platform that’s used to automate Linux’s container operations. A lot of people use it because it removes the need for people to manually operate the various processes necessary for scaling and also deploying containerized applications.

More and more people are starting to work with Kubernetes because it’s a highly effective platform that can make a lot of tasks much easier. If you are planning on working with Kubernetes, then you need to make sure that you first learn how to.

This post will tell you about the top practices you need to know about working with Kubernetes.

YAML

YAML is a data serialization language that’s common in Kubernetes, it is flexible and data-orientated. It stands for ‘Yet Another Markup Language.’ In terms of Kubernetes, it is used to specify data that’s used for configurations. You’ll need to familiarize yourself with the YAML file for Kubernetes if you intend on using it. The best way to learn about it is to read an online guide or watch instructional videos. YAML isn’t just used for Kubernetes, it is also used for more or less any application that’s used for the storage or transmission of data.

YAML Editing

It’s also worth noting that there are a variety of different editors available for writing YAML files. In addition to being able to write files, you will also need to tweak YAML files after they have been written. If you are going to need to edit YAML files, then you need to make sure that you find a program that’s right for you. The best way to do this is to read reviews, conduct research, and speak to other experienced Kubernetes developers so that you can get advice.

Default Namespaces

When you are using Kubernetes, you are able to divide a cluster into multiple environments, which you can do by using namespaces. A cluster is a set of nodes that are used to run containerized applications. A containerized application is an application, its dependents, and necessary services packaged up. Dividing clusters using namespaces will save you a lot of time. You can add the namespace preference before running the kubectl commands, instead of after. A lot of people forget to place it in after, which leads to them having to go back and make changes later on.

Using Aliases

When you are writing out Kubernetes commands, you should know that they can be extremely complex, and very lengthy. It takes a lot of time to write them. Because of this, it might help you to use aliases, which you can type in instead of writing out a full command. As you will be repeating a lot of commands when you are writing things out, it’s a good idea to use aliases, since they can help you to reduce the number of times that you have to repeat a single command. This will save you time and prevent you from growing frustrated with Kubernetes, as does tend to happen with beginners.

YAML Creation

Something else that you should know is that it’s possible to make YAML files using kubectl commands. It’s no secret that YAML files are incredibly difficult to create and work with, which makes them very annoying for people. If you are going to create YAML files, then the easiest way is to do so using kubectl commands. It is a good idea to spend some time researching how this is done before you go ahead and try to do it so that you can make sure that it is done properly. This is so that you do not make any errors or mistakes.

Extensive Research

Before you begin using Kubernetes, it is important that you conduct as much research as you can online. The reason that research is so important is so that you can learn about how to form commands and how to use the program. A lot of people, unfortunately, don’t take the time to research. The lack of research inevitably leads to them making mistakes that impact their performance. The more research you do, the easier it’ll be for you to learn how to use the program.

Taking Classes

If you want to learn how to use Kubernetes, then something that’s worth doing is taking an online class. An online class will help you to learn how to use the program, as well as how to write commands. The downside to online classes is that they aren’t usually free. You will have to pay to get involved in one of these classes. It is worth noting that the amount that’s payable usually isn’t much, but if you are on a budget then instead of taking classes, you should take some time to watch online videos and read a few guides. Videos and guides will help you to learn more effectively.

Online Communities

Another alternative to taking an online course, reading guides, and watching videos is to get involved in an online community. The internet’s rich in communities. You shouldn’t have any difficulty finding a Kubernetes community to join. If you are going to join a community, then make sure that you find one that’s active and has a lot of experienced users. An online community is so good because it will give you a place where you can ask questions, get advice, and learn things that you didn’t know before. Remember that when you are joining an online community, you need to ensure that you remain anonymous. Unfortunately, a lot of trolls participate in online forums and communities, and they can be very troublesome to deal with.

Double-checking

If at any point you have any problems with Kubernetes or you struggle to write any commands, then being a member of an online community will come in very handy. You will be able to go onto the community’s chatroom or use its private messaging feature, and you can talk to people directly there. When you are asking for help, make sure that you’re polite, personable, and friendly.

Kubernetes is a program that’s used by a lot of people. If you too want to use it, then make sure that you take the time to learn how to do so expertly. Because it’s so complex, not learning how to use it properly could mean that you aren’t able to effectively write commands and use the program properly.
