Kubernetes ConfigMaps
What are the limitations of ConfigMap?
Constraints on ConfigMaps include the inability to store binary data directly, the size limit of 1 MiB for individual entries, and the lack of data encryption. Additionally, because they lack encryption, they are not appropriate for storing private or sensitive data.
How Terraform and Kubernetes work together?
Terraform provisions and manages infrastructure resources, including Kubernetes clusters, while Kubernetes orchestrates containerized applications within those clusters, allowing seamless integration and automation of infrastructure deployment and management.
How do I create a ConfigMap from multiple files?
To create a ConfigMap from multiple files, you can use the
kubectl create configmapcommand with the--from-fileflag followed by the directory containing the files. Each file in the directory will be represented as a key-value pair in the ConfigMap.
What is a ConfigMap in deployment?
A ConfigMap in deployment refers to a Kubernetes resource used to store configuration data separately from application code. It allows you to decouple configuration settings, such as environment variables or configuration files, from the deployment artifacts, enabling easier management and flexibility in configuration updates.
How do I copy a ConfigMap from one namespace to another?
To copy a ConfigMap from one namespace to another in Kubernetes, you can use the
kubectl getcommand to retrieve the ConfigMap data from the source namespace and then apply it to the target namespace using thekubectl applycommand with the--namespaceflag set to the target namespace.
Kubernetes – ConfigMaps
An open-source container orchestration system called Kubernetes is primarily used for automated software deployment, scaling, and management. Another name for Kubernetes is K8s. Originally developed by Google, Kubernetes is now managed by the Cloud Native Computing Foundation. Although it now supports both containers and CRI-O alongside the Docker runtime, it was originally intended to interact. Automating container-managed operational tasks is the primary goal of Kubernetes. There are built-in commands for deploying the application and rolling out the desired changes to the application. It is currently used by companies such as Google, Spotify, and Capital One.
