问题 When an image has been pushed to registry V2, does the image ID will be pushed to registry as well? Is that possible to get image ID for a certain repository from V2 registry? 回答1: If the image was pushed with Docker Client 1.10 or above, you can obtain the image ID from the registry with GET /v2/<image>/manifests/<tag> Your request must include the header Accept: application/vnd.docker.distribution.manifest.v2+json In the response, the image ID will be in the Content-Docker-Digest Response

问题 I build an docker image using a Dockerfile. After building the image, I made some basic changes on the Dockerfile. Is it possible to rebuild the same image with just the additional changes. Since, it takes very long time to create the image, I don't want to build it completely. Thanks in advance. 回答1: All docker build work in the way, that you describe. The only thing need to be taken into account is layer dependencies. Consider Dockerfile FROM something RUN cmd1 RUN cmd2 RUN cmd3 RUN cmd4 If

问题 I'm new in docker. Let me describe my scenario: I made 2 docker images for a web application. one image is front-end web layer for presentation and the other is back-end layer supplying REST service. So I need to run 2 containers for this 2 images. the front-end calls services in back-end. Now I need to write the back-end's URL in front-end's code and build the image...I don't think this is the right way for micro service... because if my laptop's IP changes or others want to use my image

问题 On the local host, I can remove an image using either docker image rm or docker rmi . What if my current host is a manager node in a Docker swarm and I wish to cascade this operation throughout the swarm? When I first created the Docker service, the image was pulled down on each node in the swarm. Removing the service did not remove the image and all nodes retain a copy of the image. It feels natural that if there's a way to "push" an image out to all the nodes then there should be an equally

问题 I am trying to install Chrome on my windows container. I've created my docker image with a dockerfile and I would like to install chrome using this dockerfile. I've tried with the following command RUN apt-get update -qqy \ && apt-get -qqy install \ xvfb \ && rm -rf /var/lib/apt/lists/* /var/cache/apt/* but I have an error (I think it's because I am on windows container and this command is only for unbutu container...) : 'apt-get' is not recognized as an internal or external command, operable

问题 I just started using docker. I create an image using docker file. How can I create a new image from that existing image? 回答1: You can create a new image by using docker command $ docker build -f docker_filename . , It will first read the Dockerfile where the instructions are written and automatically build the image. The instruction in the Dockerfile contains the necessary commands to assemble an image. Once, the image is build, it will be assigned an image id. The image can be pushed to the

问题 I am trying to get my hands dirty on docker. I know that CMD or ENTRYPOINT is used to specify the start/runnable command for docker image and CMD is overridden by ENTRYPOINT . But I don't know, how does it works, when parent docker image, also has CMD OR ENTRYPOINT or BOTH ? Does child image inherit those values from parent docker image ? If so, then does ENTRYPOINT in parent image override CMD in child image ? I know that such question is already discussed at https://github.com/docker

问题 I want to implement a Machine Learning algorithm which can operate on homomorphic data using PySEAL library. PySEAL library is released as a docker container with an 'examples.py' file which shows some homomorphic encryption example. I want to edit the 'examples.py' file to implement the ML algorithm. I trying to import a CSV file in this way - dataset = pd.read_csv ('Dataset.csv') I have imported pandas library successfully. I have tried many approaches to import the CSV file but failed. How
