What is the kubectl config?

Question

Accepted Answer

**kubectl config** — **context management**.

```bash
# View current context
kubectl config current-context
kubectl config view
kubectl config view --minify

# Switch context
kubectl config get-contexts
kubectl config use-context production
kubectl config use-context staging
kubectl config use-context minikube

# Configure context
kubectl config set-context my-context --cluster=my-cluster --user=my-user --namespace=production

# Configure cluster
kubectl config set-cluster my-cluster --server=https://kubernetes.example.com --certificate-authority=ca.crt

# Configure user
kubectl config set-credentials my-user --token=my-token
kubectl config set-credentials my-user --client-certificate=client.crt --client-key=client.key

# Namespace
kubectl config set-context --current --namespace=production
kubectl config view --minify -o jsonpath='{.contexts[*].namespace}'

# Delete
kubectl config delete-context my-context
kubectl config delete-cluster my-cluster
kubectl config unset current-context

# View current configuration
kubectl config view --minify
kubectl config view --minify -o json
kubectl config view --minify -o yaml
```

**Tips:**
- Use separate contexts for dev/staging/prod.
- Default namespace for each context.
- Don't store tokens in plain text.
