k8s configmap secret

Kubernetes (k8s) provides two types of resources for managing configuration data: ConfigMaps and Secrets.

ConfigMaps are used to store non-sensitive configuration data, such as environment variables, command-line arguments, or configuration files. They can be created from literal values, directories, or files.

On the other hand, Secrets are used to store sensitive information, such as usernames, passwords, or API keys. They are base64-encoded and can be mounted as files or used as environment variables in pods.

To create a ConfigMap, you can use the `kubectl create configmap` command and provide the data using flags or a configuration file. For example:

kubectl create configmap my-config --from-literal=key1=value1 --from-file=path/to/file

To create a Secret, you can use the `kubectl create secret` command and provide the sensitive data using flags or a configuration file. For example:

kubectl create secret generic my-secret --from-literal=username=admin --from-file=path/to/file

Both ConfigMaps and Secrets can be mounted as volumes or used as environment variables in pods. You can reference them in the pod's YAML file using the `env` or `volumes` sections.

I hope this helps! Let me know if you have any more questions.
