What is the difference between manifest and ConfigMap?
Using ConfigMaps

ConfigMaps are ideal for most situations where you want to supply environment-specific configuration values to your pods. They store key-value pairs and make them available to pods as environment variables, command line arguments, or files in a mounted volume.A Kubernetes Manifest file is a YAML or JSON file that describes the desired state of a Kubernetes object. These objects can include deployment, replica set, service, and more. Manifest files define the specifications of the object, such as its metadata, properties, and desired state.What is the difference between ConfigMaps and Secrets in Kubernetes ConfigMaps are used to store non-sensitive configuration data, such as environment variables or configuration files. Secrets, on the other hand, are designed for storing sensitive information like passwords, API keys, or TLS certificates.

What is ConfigMap used for in Kubernetes : Kubernetes ConfigMap is a built-in Kubernetes API object that's designed to store your application's non-sensitive key-value config data. ConfigMaps allow you to keep config values separate from your code and container images. Values can be strings or Base64-encoded binary data.

What are the benefits of ConfigMap

Pods can consume ConfigMaps as environment variables, command-line arguments, or as configuration files in a volume. A ConfigMap allows you to decouple environment-specific configuration from your container images, so that your applications are easily portable.

What is config map used for : ConfigMaps are a Kubernetes mechanism that let you inject configuration data into application pods. The ConfigMap concept allow you to decouple configuration artifacts from image content to keep containerized applications portable.

A manifest file is a simple text file that provides important information about a computer program or project. It contains information such as the names of all the files included in the project, the version of the project, and the author.

to make clear or evident; show plainly: He manifested his approval with a hearty laugh. to prove; put beyond doubt or question: The evidence manifests the guilt of the defendant.

What is the difference between ConfigMap and secret priority

If, for whatever reason, you enabled both configmaps and secrets, and there is a common property between them, the value from the ConfigMap will have a higher precedence. That is: it will override whatever values are found in secrets.Where Are Kubernetes ConfigMaps Stored Kubernetes stores API objects like ConfigMaps and Secrets within the etcd cluster. Etcd is essentially the brain of Kubernetes, since it stores all of the key-value objects that Kubernetes requires to orchestrate the containers.A ConfigMap is not designed to hold large chunks of data. The data stored in a ConfigMap cannot exceed 1 MiB. If you need to store settings that are larger than this limit, you may want to consider mounting a volume or use a separate database or file service.

The ConfigMap applies globally, meaning that it affects every Ingress resource. In contrast, annotations always apply to their Ingress resource. Annotations allow overriding some ConfigMap keys. For example, the nginx.org/proxy-connect-timeout annotations overrides the proxy-connect-timeout ConfigMap key.

What is the maximum size of ConfigMap : The size of the individual configmap is limited to 1mb, according to kubernetes.io: A ConfigMap is not designed to hold large chunks of data. The data stored in a ConfigMap cannot exceed 1 MiB.

Where is ConfigMap stored in Kubernetes : Kubernetes stores API objects like ConfigMaps and Secrets within the etcd cluster.

What is a manifest example

As an adjective, manifest is a formal way to say that something is apparent to the senses and is synonymous with evident, apparent, or clear. If you have strong feelings about something, they will be manifest on your face. A ship or plane's manifest is the list of cargo or passengers on a particular trip.
