If true, keep the managedFields when printing objects in JSON or YAML format. Selector (label query) to filter on, supports '=', '=', and '!='.(e.g. This flag is useful when you want to perform kubectl apply on this object in the future. Otherwise, the annotation will be unchanged. If true, the configuration of current object will be saved in its annotation. Useful when you want to manage related manifests organized within the same directory. Process the directory used in -f, -filename recursively. If not set, default to updating the existing annotation value only if one already exists. If set to false, do not record the command. ![]() Record current kubectl command in the resource annotation. Uses the transport specified by the kubeconfig file. One of: json|yaml|name|go-template|go-template-file|template|templatefile|jsonpath|jsonpath-as-json|jsonpath-file. This flag can't be used together with -f or -R. Name of the manager used to track field ownership.įilename, directory, or URL to files to use to create the resource If server strategy, submit server-side request without persisting the resource. If client strategy, only print the object that would be sent, without sending it. Only applies to golang and jsonpath output formats. If true, ignore any errors in templates when a field or map key is missing in the template. ![]() pod.jsonĬreate a pod based on the JSON passed into stdin cat pod.json | kubectl create -f -Įdit the data in docker-registry.yaml in JSON then create the resource using the edited data kubectl create -f docker-registry.yaml - edit -o jsonĬreate a resource from a file or from stdin. Once your workloads are running, you can use the commands in theĬreate a pod using the data in pod.json kubectl create -f. expose will load balance traffic across the running instances, and can create a HA proxy for accessing the containers from outside the cluster.run will start running 1 or more instances of a container image on your cluster.Lets start by deploying a new namespace and an example pod so that we have something to work with.This section contains the most basic commands for getting a workload ![]() No more logging in and being dumped into the default namespace. Remember in the previous post where we talked about namespaces and how we could logically separate our Kubernetes cluster? Now we can use KUBECONFIG and context to set our default namespaces. So a context would include a cluster, a user and a namespace. Lastly, the KUBECONFIG file stores contexts.Ĭontexts group access information under an easily recognizable name. It also stores authentication information such as username/passwords, certificates or tokens. The KUBECONFIG file contains several things of interest including the cluster information so that kubectl is executing commands on the correct cluster. This is why you would’ve needed to add this file to your $PATH variable so that it could be used correctly by the kubectl commands. When you use kubectl to execute commands, it gets the correct communication information from this KUBECONFIG file. This is the KUBECONFIG file and it is used to store information about your connection to the Kubernetes cluster. When you first setup your Kubernetes cluster you created a config file likely stored in your $HOME/.kube directory. ![]() This might be a good time to introduce Kubernetes KUBECONFIG files and context so you can more easily use all of these different resources. You’ve been working with Kubernetes for a while now and no doubt you have lots of clusters and namespaces to deal with now. ![]()
