TL;DR
  • Imperatively Create a Resources

Creating Resources

Motivation

Create Resources directly from the command line for the purposes of development or debugging. Not for production Application Management.

Deployment

A Deployment can be created with the create deployment command.

kubectl create deployment my-dep --image=busybox

Running and Attaching

It is possible to run a container and immediately attach to it using the -i -t flags. e.g. kubectl run -t -i my-dep --image ubuntu -- bash

ConfigMap

Create a configmap based on a file, directory, or specified literal value.

A single configmap may package one or more key/value pairs.

When creating a configmap based on a file, the key will default to the basename of the file, and the value will default to the file content. If the basename is an invalid key, you may specify an alternate key.

When creating a configmap based on a directory, each file whose basename is a valid key in the directory will be packaged into the configmap. Any directory entries except regular files are ignored (e.g. subdirectories, symlinks, devices, pipes, etc).

# Create a new configmap named my-config based on folder bar
kubectl create configmap my-config --from-file=path/to/bar
# Create a new configmap named my-config with specified keys instead of file basenames on disk
kubectl create configmap my-config --from-file=key1=/path/to/bar/file1.txt --from-file=key2=/path/to/bar/file2.txt
# Create a new configmap named my-config with key1=config1 and key2=config2
kubectl create configmap my-config --from-literal=key1=config1 --from-literal=key2=config2
# Create a new configmap named my-config from an env file
kubectl create configmap my-config --from-env-file=path/to/bar.env

Secret

Create a new secret named my-secret with keys for each file in folder bar

kubectl create secret generic my-secret --from-file=path/to/bar

Bootstrapping Config

Imperative commands can be used to bootstrap config by using --dry-run -o yaml. kubectl create secret generic my-secret --from-file=path/to/bar --dry-run -o yaml

Namespace

Create a new namespace named my-namespace

kubectl create namespace my-namespace

Auth Resources

ClusterRole

Create a ClusterRole named "foo" with API Group specified.

kubectl create clusterrole foo --verb=get,list,watch --resource=rs.extensions

ClusterRoleBinding

Create a role binding to give a user cluster admin permissions.

kubectl create clusterrolebinding <choose-a-name> --clusterrole=cluster-admin --user=<your-cloud-email-account>

Required Admin Permissions

The cluster-admin role maybe required for creating new RBAC bindings.

Role

Create a Role named "foo" with API Group specified.

kubectl create role foo --verb=get,list,watch --resource=rs.extensions

RoleBinding

Create a RoleBinding for user1, user2, and group1 using the admin ClusterRole.

kubectl create rolebinding admin --clusterrole=admin --user=user1 --user=user2 --group=group1

ServiceAccount

Create a new service account named my-service-account

kubectl create serviceaccount my-service-account
