kubernetes/ -n production Deployment fileĪ 'deployment' is an instruction with which Kubernetes will set up our service.
Then apply the Namespace configuration by typing the following in the terminal: 1 kubectl apply -f. This one is nice and short: 1 # /kubernetes/ 2apiVersion: v1 We provide a namespace, so that we can easily develop for different environments. Once this is done, we need to make sure that we create the files needed to organize everything within the cluster. Now we have something to deploy to (the cluster on DigitalOcean).
To see the existing nodes in the cluster we use: 1 kubectl get nodes To save our configuration locally and adjust the context we use the following: 1 doctl kubernetes cluster kubeconfig save humanoids-k8s We called the cluster humanoids-k8s in this way and we used ams3 (Amsterdam) as a region. To create our first cluster we use the following in the terminal: 1 doctl kubernetes cluster create humanoids-k8s -region ams3 First we log in to DigitalOcean: 1 doctl auth init -access-token = For this we still need an Access token from DigitalOcean. Setting up a Kubernetes Cluster in Digital Oceanįirst of all, we are going to set up a Kubernetes Cluster.
#Kubernetes docker for mac ingress windows
Homebrew for MacOS users or Chocolatey for Windows for installing the different CLIs.This way you can configure a Kubernetes cluster in a few steps. DigitalOcean is very popular because they offer a lot of "value for money" and the use of the services is straightforward. DigitalOceanĭigitalOcean is a cloud provider, comparable to Amazon Web Services or Microsoft Azure. This is a collection of nodes and also the one in which we set up all the aforementioned components. These configuration files that are stored ensure that 'pods', that where containers are stored in, are containerized in a 'node'. When using Kubernetes, three components are usually defined: a 'deployment', a 'service' and an 'ingress'. It is a system for deployment, automatic scaling up and down and management of containerized apps. Kubernetes allows us to "orchestrate containers". The service can be started from this container. The service that is built with the template then lives in a Docker container.
You can therefore also imagine it as the template for a service. The image therefore contains all the building blocks and instructions needed to create a service. This is a set of instructions where step-by-step all the necessities to run the service are discussed from using a (small) operating system as a basis, to installing all packages and both building and starting the service. For the sake of completeness, we briefly summarize each technique here.
The following techniques are all discussed to realize the cloud infrastructure. In this article we show how you can set up your own Kubernetes infrastructure at DigitalOcean. The advantages of this are that the configuration is made transparent, that it can be easily adjusted and that the entire infrastructure can be migrated fairly easily to another cloud provider.Īt Humanoids we also like to use this principle and we prefer to do that with the help of Kubernetes. This principle means that you control the infrastructure of your service from files in the service or directly linked to the service.
