The function Remove-DockerImages just iterate through the array of image names so I will not mention it again.ĭue to we defined all our logic into functions we can just call them one by one and all work is done. Function Remove-DockerImageĪs you can see above we are also checking if there exists Docker image with the name we passed as a parameter to the Remove-DockerImage function. The Remove-DockerImage function is called from the loop in which we iterate through an array of Docker image names we have defined in string array $dockerImagesToRemove. And that's exactly what I do in Remove-DockerContainers function: Function Remove-DockerContainersĪfter the previous step, we can start removing Docker images. If yes, we need to stop them before and then remove.
#Docker remove container if exists how to#
Now let's look into it and explain it step by step.īefore we start removing Docker images we need to check if there are running containers. Example 1: docker remove all containers docker rm (docker ps -a -q) Example 2: how to remove all docker container at once to remove all the docker. If there are existing containers for a service, and the service’s. Running docker-compose up -detach starts the containers in the background and leaves them running. When the command exits, all containers are stopped. Remove-DockerImages -DockerImages $dockerImagesToRemove The docker-compose up command aggregates the output of each container (essentially running docker-compose logs -follow ). But that can be easily fixed if you use persistent volumes to store your data. $dockerImagesToRemove = 'my-docker-image/name3', 'my-docker-image/name2') Answer (1 of 2): Yes, once your container ceases to exist or you restart it, the data will be lost.
# Array of docker images we want to remove Remove-DockerImage -DockerImage $DockerImage docker run -d -name mariadb \ -env ALLOWEMPTYPASSWORDyes \ -env MARIADBUSERbnopencart \ -env MARIADBPASSWORDbitnami \ -env MARIADBDATABASEbitnamiopencart \ -network opencart-network.
Create a MariaDB container with host volume. Building on Xiong Chiamiov's answer, which correctly identified the root cause of the problem - the dir reference by relative path when attempting to empty or delete that directory depends on the working directory at the time, which was not correctly set in the cases mentioned in the OP. Write-Host ($DockerImage + " image not exists") -ForegroundColor Red Step 1: Create a network (if it does not exist) docker network create opencart-network. # show mesage that docker image does not exist Write-Host ($DockerImage + " image was removed") -ForegroundColor Green $selectedDockerImages = (docker images -all $DockerImage -quiet) Write-Host ("removing docker containers: ") $containersIds = (docker ps -all -quiet) # save containers ids into array (-quiet mean return just containers ids) There is a whole script that will stop all Docker containers than remove them and also remove our Docker images we defined in the array $dockerImagesToRemove.Ĭreate new PowerShell script remove-docker-images.ps1 and copy paste all script below: Function Remove-DockerContainers
