docker stop command is for : Stop a running containerdocker kill command is for : Kill a running container

The docker update command dynamically updates container configuration & prevent containers from consuming too many resources from Docker host.

docker wait command is used to block the container until the container exit. once the container is stoped, it returns the exit code (0)

The docker wait command blocks the container till it is stopped Eg. docker wait 829414517f17

Block until one or more containers stop, after that it print their exit codes.root@ip-172-31-28-155:/home/ubuntu# docker wait test_httpd root@ip-172-31-28-155:/home/ubuntu# docker stop test_httpdtest_httpd root@ip-172-31-28-155:/home/ubuntu# docker wait test_httpd0

Docker Hub is a service provided by Docker for finding and sharing container images. Teams & Organizations can pull publicly available docker images for their usage. Top 5 docker repository Rank Repository 1 ubuntu 2 centos 3 nginx 4 redis 5 node

Docker update command updates the container properties. In the below example I have update –memory-reservation

docker wait command will block one or multiple containers until it is stopped. Once the container is stopped it will retun 0 meaning that the container is stopped.

docker update command is used to update the default configuration of a specific container.for example, limiting resources like memory, cpu etc

Docker wait command block until one or more containers stop, then print their exit codes Usage

Block until one or more containers stop, then print their exit codes. Example: Terminal 1: root@ip-172-31-28-155:/home/ubuntu# docker wait test_su1 Terminal 2: root@ip-172-31-28-155:/home/ubuntu# docker stop test_su1 Terminal 1: root@ip-172-31-28-155:/home/ubuntu# docker wait test_su10

Q1. – What is the use of “docker update” commands? with example and image The docker update command dynamically updates container configuration. it prevent containers from consuming too many resources such as CPU and memory from their Docker host. ex:

A Loop is an Iterative Control Structure that involves executing the same number of code a number of times until a certain condition is fulfilled Types of Loops in PHP while  do-while loop for loop foreach loop 1 . While :-The while loop is an entry control loop like for loops i.e., it first check the condition at the start of the loop and if its true then it enters the loop and executes the block of statement which is

The docker update command dynamically updates container configuration. For example : We can update a container’s kernel memory limit using the –kernel-memory option. You can update kernel memory while the container is running using below command:

Used for updating the various confgurations of a container or multiple containers. We can update the configuration of running/stopped containers except –kernel-memory. Various Options available. Use case: The main usecase is to limit the amount of host resources like CPU, RAM , that can be used by the container.

Docker update command is used to update the configuration of the already created docker image. We can update the CPU, memory etc. by using the update command. Eg : docker update –memory 8M 829414517f17 Result : 829414517f17 aji_0 0.00% 7.445MiB / 8MiB 93.07% 1.51kB / 0B 0B / 0B 82

Image 1: Ran golang image and executed the image to get the go version. Image2:Ran python image and executed the container Image3:Ran openjdk image and executed the container for java version Image4:Searched for some fun image and got cat image (docker run –rm -it wernight/funbox nyancat) Image5: Create a container for alpine image and excuted to add curl into the container

docker update command is to set limits to a single container or multiple contianers. We can limit such as input/output resources, cpu runtime period, cpu-quota and cpu shares.
