Not understanding the code written in jenkins file-CodePudding

i have found the following code in a jenkins file in my project. i am new to aws and docker and not understanding the logic behind this code, guys help me out on what is happening here

            sh "docker run --rm -i -e AWS_ACCESS_KEY_ID -e AWS_SECRET_ACCESS_KEY -e AWS_REGION "  
               '--name "${CONTAINER_ID}" "${IMAGE_TAG}" '  
               "node -r esbuild-runner/register ./scripts/restartExecution.ts "  

               (params.DryRun? "--dry-run " : "")  
               "--started-after ${StartedAfter} "  
               (params.StartedBefore? "--started-before ${params.StartedBefore} " : "")  
               "--state-machine-arn ${params.StateMachineARN} "  
               "--status ${params.Status} "

CodePudding user response：

It is pretty straightforward

docker run --rm -i -e AWS_ACCESS_KEY_ID -e AWS_SECRET_ACCESS_KEY -e AWS_REGION '--name "${CONTAINER_ID}" "${IMAGE_TAG}" '

The docker run command first creates a container layer over the specified image, and then starts it using the specified command.(from docs) Pass the three

AWS_ACCESS_KEY_ID
AWS_SECRET_ACCESS_KEY
AWS_REGION

as environmental variables.

Sometimes it is useful to show the commands that a shell script will execute,that is why dry-run was added.

More about options in official docs

-rm remove container after it exits -i interactive mode
