What is kubernetes context
The first line is a separator, and is optional unless you’re trying to define multiple structures in a single file. For example, you might have a config file that starts like this:. Maps let you associate name-value pairs, which of course is convenient when you’re trying to set up configuration information. That’s not to say there aren’t more complex things you can do, but in general, this is all you need to get started. You might have maps of lists and lists of maps, and so on, but if you’ve got those two structures down, you’re all set. There are only two types of structures you need to know about in YAML: Still, there may be situations where the JSON format is more convenient, so it’s good to know that it’s available to you.įortunately, YAML is relatively easy to learn. Even if you’re only trying to find examples on the web, they’re most likely in (non-JSON) YAML, so we might as well get used to it. On the other hand, that’s not very likely, unfortunately. So on the one hand, if you know JSON and you’re only ever going to write your own YAML (as opposed to reading other people’s) you’re all set. YAML is a superset of JSON, which means that any valid JSON file is also a valid YAML file. Maintenance : YAML files can be added to source control, such as a Github repository so you can track changesįlexibility : You’ll be able to create much more complex structures using YAML than you can on the command line When defining a Kubernetes manifest, YAML gives you a number of advantages, including:Ĭonvenience : You’ll no longer have to add all of your parameters to the command line For example, in this article, we’ll pick apart the YAML definitions for creating first a Pod, and then a Deployment. YAML, which stands for Yet Another Markup Language, or YAML Ain’t Markup Language (depending who you ask) is a human-readable text-based format for specifying configuration-type information.
WHAT IS KUBERNETES CONTEXT SOFTWARE
tls-server-name="" Server name to use for server certificate validation.It’s difficult to escape YAML if you’re doing anything related to many software fields - particularly Kubernetes, SDN, and OpenStack. s, -server="" The address and port of the Kubernetes API server A value of zero means don't timeout requests. Non-zero values should contain a corresponding time unit (e.g. request-timeout="0" The length of time to wait before giving up on a single server request. profile-output="profile.pprof" Name of the file to write the profile to One of (none|cpu|heap|goroutine|threadcreate|block|mutex) profile="none" Name of profile to capture.
WHAT IS KUBERNETES CONTEXT PASSWORD
password="" Password for basic authentication to the API server n, -namespace="" If present, the namespace scope for this CLI request match-server-version=false Require server version to match client version kubeconfig="" use a particular kubeconfig file This will make your HTTPS connections insecure
insecure-skip-tls-verify=false If true, the server's certificate will not be checked for validity. context="" The name of the kubeconfig context to use cluster="" The name of the kubeconfig cluster to use client-key="" Path to a client key file for TLS client-certificate="" Path to a client certificate file for TLS certificate-authority="" Path to a cert file for the certificate authority cache-dir="/builddir/.kube/cache" Default cache directory Tye will use your current credentials for pushing Docker images and accessing Kubernetes clusters. azure-container-registry-config="" Path to the file containing Azure container registry configuration information. Tye makes the process of deploying your application to Kubernetes very simple with minimal knowlege or configuration required. as-uid="" UID to impersonate for the operation. as-group= Group to impersonate for the operation, this flag can be repeated to specify multiple groups. User could be a regular user or a service account in a namespace. as="" Username to impersonate for the operation. Note: If the context being renamed is the 'current-context', this field will also be updated. NEW_NAME is the new name you want to set. Renames a context from the kubeconfig file.ĬONTEXT_NAME is the context name that you want to change. Kubectl config rename-context Description Tools like gcloud write new context entries to KUBECONFIG0 or HOME/.kube/config, obscuring the multi-config solution and making it less likely that new. Rename a context from the kubeconfig file
