egalink / docker-container-exists.sh

Last active July 17, 2025 09:02

Checks if a docker container exists and is running.

	#!/bin/bash

	# To check if a Docker container exists, you can use
	# the docker ps command. However, it only shows the running containers.

	# If you want to check if a container with a specific name exists,
	# regardless of whether it is running or not, you can use
	# the docker inspect command. It will return information about the container,
	# and if it does not exist, it will return an error.
