kubectx VS kops

kubectx: brew install kubectx

default is where any actions which require a namespace will go into if one is not explicitly defined in a default setup (tools such as kubens can alter this behavior). In the context of Jenkins, namespaces are a useful way to allow isolation of individual Jenkins instances that want to utilize the same Kubernetes cluster. Creation of a namespace is a simple option to kubectl:

Here you go: https://github.com/ahmetb/kubectx and https://kubecm.cloud/

check out kubectx/kubens https://github.com/ahmetb/kubectx very handy tool to permanently switch context/namespace

kubectx + kubens v0.9.4

For a peek at what's currently possible, visit the documentation site, in particular the Usage section. For this initial release, it has feature parity with kubectx and kubens and that's about it, but there's lots of room for growth.

I also encourage you to install kubectx + kubens to navigate Kubernetes easily.

The general problem of patching resource definitions that are not fully under your control has also been recognized for some time. This is true of default resources created and updated by cluster maintenance tools (e.g. kOps), or by public helm charts that you use to install common services and operators (e.g. nginx-ingress, cert-manager, and so on). High quality charts will allow you to override the configuration of important components such as service account references, but some simpler charts offer much less configuration.

The kops documentation is not very clear about this.

Very fast progress and great article with lots of useful information. I found myself nodding a lot having recently seen GitLab Dedicated https://docs.gitlab.com/ee/subscriptions/gitlab_dedicated/ being developed that had my similar challenges. I wonder what other people think of Kops https://kops.sigs.k8s.io/

note: I work with kube on a daily basis. All current clusters under my care use a managed backplane service though there are a number of small (3+ years-old) clusters that I still keep an eye on that were initialized using kops.

kOps with your own instances.

Companies run their own clusters (sometimes for cost reasons), using tools like kops, and kubeadm to set up their own clusters.

curl -Lo kops https://github.com/kubernetes/kops/releases/download/$(curl -s https://api.github.com/repos/kubernetes/kops/releases/latest | grep tag_name | cut -d '"' -f 4)/kops-linux-amd64 chmod +x kops sudo mv kops /usr/local/bin/

Kops is a cluster setup and management command line tool that deploys a Kubernetes cluster to AWS. It provides configuration abstractions such as manifest YAML files that facilitate node and components configuration. And like Ansible, it will provide dry-run capabilities and ensures idempotency of changing the nodes.
