How to delete cached/intermediate docker images after the cache gets invalidated

余生颓废 提交于 2021-02-07 14:30:37
问题 I have a CI-pipeline that builds a docker image for my app for every run of the pipeline (and the pipeline is triggered by a code-push to the git repository.) The docker image consists of several intermediate layers which progressively become very large in size. Most of the intermediate images are identical for each run, hence the caching mechanism of docker is significantly utilized. However, the problem is that the final couple layers are different for each run, as they result from a COPY

问题 While building up a docker image through dockerfile, I have to clone a github repo. I have added my public ssh keys to my git hub account and i am able to clone the repo from my docker host. While i see that i can use docker host's ssh key by mapping $SSH_AUTH_SOCK env variable at the time of docker run like docker run --rm -it --name container_name \ -v $(dirname $SSH_AUTH_SOCK):$(dirname $SSH_AUTH_SOCK) \ -e SSH_AUTH_SOCK=$SSH_AUTH_SOCK my_image . How can i do same during docker build ? 回答1

问题 I am just looking at docker images in https://hub.docker.com/_/node/ For every version, the images are categorized into Alpine, Jessie, Stretch, Buster etc. What's their meaning? 回答1: Those are the names of the OS in the container in which Node will be running. Alpine is for Alpine Linux, Jessie and Stretch are versions of Debian. If you scroll down on the documentation link you provided, you'll find a section describing what Alpine is and why you might want to use it. 回答2: In docker-Context

问题 System : I've a Windows Server 2019 OS installed with a NVIDIA Tesla T4 Tensor Core GPU. Goal : Planning to read real time streaming videos from an IP camera and to further process frame by frame.

If not, is there any
