In Kubernetes, a rollout restart is a process that updates the Pod's configuration, such as containers, ports, and environment variables, by creating new Pods with the updated settings and removing the old ones, one by one, ensuring uninterrupted service. This process is supported for Kubernetes controllers, including Deployment, StatefulSet, and DaemonSet. These controllers enable various actions related to Pod management, such as deployment, scaling, updating pods, and more.

In Docker Compose, environment variables can be defined in the form of a list of key-value pairs in a file named .env located in the root directory of your project.

In Kubernetes, a Secret is an object that stores sensitive data for containers to use in the form of a key-value pair, such as a password, a token, or an access key.

In Kubernetes, Pods provide a shared environment for one or more containerized applications, allowing the containers to communicate and share common resources.

In Docker Compose, a network refers to a layer allowing the containers of the services defined in the compose.yaml file to communicate with each other.

In Kubernetes, events provide detailed information for the activities related to Kubernetes objects such as pods, nodes or containers, and are used for observability and troubleshooting issues like when your pod isn’t running or your container crashes.

In Kubernetes, every operation is executed in a context that groups access settings for clusters, namespaces, and users. Using contexts is useful when managing multiple clusters, namespaces, or users, as it eliminates the need to specify their values for every executed kubectl command.

In Docker, a port refers to a communication endpoint between the host and a container through which a containerized application can send and receive data.

In Kubernetes, Pods create a shared environment for one or more containerized application. This shared environment allows containers to communicate and share common resources easily.

In Kubernetes, namespaces provide a logical way to separate resources within an application, forming isolated virtual clusters within the Kubernetes cluster. For example, you can create namespaces for the development and production environments and manage their resources independently.

In Docker Compose, the target property in the build section of a Compose file is used to select a specific stage from a multi-stage Dockerfile , enabling the building of specific stages or utilization for different environments with a single Dockerfile

In Kubernetes, namespaces provide a logical way to separate resources within an application, forming isolated virtual clusters within the Kubernetes cluster. For example, you can create namespaces for the development and production environments and manage their resources independently.

To restart one or more Docker containers, you can use the docker restart command as follows: $ docker restart <container …>

Dev dependencies are packages required only for the development phase and not for the application to run in production. Some common examples of such packages are testing frameworks (jest, cypress, karma, mocha), code linters (prettier, eslint), build tools (babel, webpack), and more.
