docker-image

问题 In the dockerfile, suppose I set a LABEL immediately after the FROM command, then is the label applied to every intermediate container and image generated in the subsequent step? I know that intermediate containers get removed during build after each step. But I am facing an issue where-in some of the intermediate container are not getting removed. This is causing the images created out of these containers (during the build process) to become dangled. I can see the images in docker images and

问题 I have a bunch of Docker containers running on a server and I used the "latest" tag or no tag at all for all of them. Now I want to freeze the image versions, but I have no idea when I pulled these images, so I can't tell which version "latest" is referring to. docker ps is just showing me that the containers use the "latest" or no tag, like this: # docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 371d6675888b node:latest "npm start" 6 days ago Up 2 hours project_xyz_1

问题 When we use Docker it's very easy push and pull image in a public repository in our https://hub.docker.com but this repository it's free only for public image(only one can be private). Currently it's possible to execute a reverse engineering of a public image in repository and read the source code of project ? 回答1: You can check how an image was created using docker history <image-name> --no-trunc Update: Check dive which is a very nice tool that allows you to views image layers. 回答2: As

问题 I'm trying to push my docker image to google container image registry but get an error which says I do not have the needed permission to perform this operation. I have already tried gcloud auth configure-docker but it doesn't work for me. I first build the image using: docker build -t gcr.io/trynew/hello-world-image:v1 . Then I'm trying to attach a tag and push it: docker push gcr.io/trynew/hello-world-image:v1 This is my output : The push refers to repository [gcr.io/trynew/hello-world-image

问题 I want to be able to read the contents of the file ~/.ssh/id_rsa and pass the same to my build stage of the image. When I use the command docker build --build-arg SSH_PRIVATE_KEY="$(cat ~/.ssh/id_rsa)" and then I try to echo that inside the container during a build, I get empty. RUN echo "$SSH_PRIVATE_KEY" > /priv_key \ && cat /priv_key the result is Step 6/14 : RUN echo "$SSH_PRIVATE_KEY" > /priv_key && cat /priv_key ---> Running in c8d6e3c88cd8 Removing intermediate container c8d6e3c88cd8

问题 I wanna create a docker image from an ISO file. and I meet the same question like this iso to docker file I did same operations with him , and I know it's wrong now. now what i have is: an ISO file. my own ISO file, based on ubuntu but it's not ubuntu. a computer, running ubuntu on it. and I wanna know the detail operations to create a docker image from this ISO file. if use VM, I hope i could get certainly operations. or if don't need VM, what should I do ? I have searched many docs... like
