kubectl namespace context configuration¶
kubectl uses a context to determine the cluster, user, and default namespace for command-line operations. By default, if no namespace is specified, the default namespace is used.^[400-devops__06-Kubernetes__k8s-ithelp__Day22__README.md] To avoid repeatedly passing the --namespace flag, you can configure the current context to permanently set a preferred namespace for subsequent commands^[400-devops__06-Kubernetes__k8s-ithelp__Day22__README.md].
Setting a Persistent Namespace¶
To change the default namespace for the current context, use the kubectl config set-context command with the --namespace flag^[400-devops__06-Kubernetes__k8s-ithelp__Day22__README.md]. Applying the --current flag updates the active context immediately^[400-devops__06-Kubernetes__k8s-ithelp__Day22__README.md].
Command Syntax
[kubectl](<./kubectl.md>) config set-context --current --namespace=<namespace-name>
Verification
To verify that the configuration has been applied, you can use the config view command^[400-devops__06-Kubernetes__k8s-ithelp__Day22__README.md].
[kubectl](<./kubectl.md>) config view --minify | grep namespace:
Alternative: Request-Level Specification¶
If a persistent change is not desired, the namespace can be specified for individual requests using the --namespace parameter^[400-devops__06-Kubernetes__k8s-ithelp__Day22__README.md].
[kubectl get pods](<./kubectl-get-pods.md>) --namespace=demo-namespace
[kubectl](<./kubectl.md>) run nginx --image=nginx --namespace=demo-namespace
