It seems confusing to me. Is my understanding that it has two meanings, as below, correct?
Docker CLI means the usual thing: command-line interface of Docker. It’s available when Docker is installed (package docker from AUR in my case). (Though docker-cli-bin is also available. Description: "Docker – CLI utility only, installed from static binary on docker.com".)
Compose CLI is Docker Compose "Cloud Integrations". It’s an add-on to Docker Compose. The package with which it’s installed (in addition to docker-compose for just Compose) is docker-compose-cli.
>Solution :
Yes, your understanding is correct.
The Docker CLI is the command-line interface for the Docker engine, which is used to manage Docker images, containers, and networks. The Docker CLI is available when the Docker engine is installed on your system, which can be done through a package manager like apt or yum, or by downloading the Docker binaries from Docker’s website.
Docker Compose is a separate tool that is used to define and run multi-container Docker applications. Docker Compose uses a YAML file to configure the application’s services, and then it uses the Docker CLI to create and start the services.
The Docker Compose CLI is an add-on to Docker Compose that provides additional features and functionality, such as the ability to manage Docker Compose applications on multiple hosts, or in the cloud. The Docker Compose CLI can be installed as a separate package, such as docker-compose-cli, in addition to the docker-compose package that provides the core Docker Compose functionality.
