Read moreDocker container is a lightweight execution environment where a user can run their applications.These are working application created from docker images and a user can start an instance of the application. All the necessary resource and packages to run an application is availble in the docker image. A container created will have all the root file system that of a linux environment f the image is of linux architecure. for eg: Below is the container started from an httpd docker

Read moreDocker stop will gracefully stop the container. It stops the processes before killing the container Docker kill will kill the container immediately
Read moreThe docker pause command suspends all processes in the specified containers. On Linux, this uses the freezer cgroup. The docker unpause command un-suspends all processes in the specified containers.
Read moreThe docker container is an independent light weight environment for running an application, docker image is the package used to create, run and deploy application in containers.
Read moredocker stop – The main process inside the container will receive SIGTERM, and after a grace period, SIGKILL. docker kill – The main process inside the container is sent SIGKILL signal (default)
Read moreDocker pause suspends all the process to container. Docker unpause will un-suspend all the process to container
Read moreIt is a container which provide you an environment to run your application. You can create a container with all the basic setup needed for your application to run and run your application
Read moredocker stop It is stopping a running docker container. It is a graceful termination of docker container with exit code – Exited (0) docker kill It is killing a running docker container. It is a forceful termination of docker container with exit code – Exited (137)
Read moreDocker pause is used to pause the running container which can be resumed with unpause. But is we stop or kill we can not unpause but we can restart. docker create –name vin6 httpddocker start vin6docker psdocker stop vin6 docker ps -adocker start vin6docker pause vin6docker ps -adocker unpause vin6docker images -adocker ps -adocker stop vin6docker restart vin6docker psdocker kill vin6
Read more2. What is the difference between docker stop and docker kill? Docker stop / kill commands are used to stop the running docker container. After docker stop <name>, “docker ps -a ” will show the status as Exited (0) But after docker kill <name>, “docker ps -a ” will show the status as Exited (137).ie, docker stop sends SIGTERM as process end signal and SIGKILL is send by docker kill. root@ip-172-31-28-155:/home/ubuntu# docker start abhiabhiroot@ip-172-31-28-155:/home/ubuntu# docker ps -a | grep abhi2d0eb09c5f08

Any no.of containers can run the same image. Q2. What is the differenece between docker stop and docker kill?Docker stop is gracefully stopping a container, first SIGTEM is sent for cleanup and then SIGKILLDocker kill is forcefully terminating a container directly sending SIGKILL Q3. What is the difference between docker pause and
Read moreDocker container is an instance of a docker image. Docker image has all minimal items to run an app like rootfs,userfs and appfs.
Read moredocker stop and docker kill doing the same thing only the internal process have difference. Both stops a running container to an exit state. docker create –name vin6 httpddocker start vin6docker psdocker stop vin6docker ps -adocker start vin6docker pause vin6docker ps -adocker unpause vin6docker images -adocker ps -adocker stop vin6docker restart vin6docker psdocker kill vin6
Read moreQ1. Explain What is Docker Container with image? Docker container with image is an executable software package built on top of its own root file system. Every docker image will have its own docker container. Q2. What is the difference between docker stop and docker kill? ‘stop’ commands does graceful shutdown….where ‘kill’ command does a forceful kill. The status code will be different for both eventhough the status is same (Exited) after stop command, exit code is 0 Q3. What
Read moredocker stop will accept the time in other words it’ll not force the process to stop. But the docker kill will force the running process to stop. When we use the command docker stop on the stopped container, it will not throw any error. But if we try using the docker kill command on the stopped container it will throw an error.
