问题 I am using RUN instruction within a Dockerfile to install a rpm RUN yum -y install samplerpm-2.3 However, I want to pass the value "2.3" as an argument. My RUN instruction should look something like: RUN yum -y install samplerpm-$arg where $arg=2.3 回答1: You are looking for --build-arg and the ARG instruction. These are new as of Docker 1.9. Check out https://docs.docker.com/engine/reference/builder/#arg. This will allow you to add ARG arg to the Dockerfile and then build with docker build -

问题 I'm deploying some images from my registry into my application server using docker swarm mode hos t : My image in the registry is looking like this (executing docker images ) : REPOSITORY TAG IMAGE ID CREATED SIZE localhost:5000/myApp G02R00C09_myTag c1fc2242f9a0 2 hours ago 272MB Under my docker compose file , my service looks like this : --- version: '3.4' services: ihm: image: myRegistryServer:5000/myApp:G02R00C09_myTag stdin_open: true volumes: - /opt/logs:/opt/logs tty: true ports: -

问题 Given a docker registry managing multiple docker repositories, how do I delete one of the repositores? In my case, curl -X GET localhost:5000/v2/_catalog {"repositories":["repo1", "repo2", "repo3"]} I want to remove repository repo1 so that _catalog looks like curl -X GET localhost:5000/v2/_catalog {"repositories":["repo2", "repo3"]} We can see repo1 appears to have only the default "latest" image tag. curl -X GET localhost:5000/v2/repo1/tags/list {"name":"repo1","tags":["latest"]} (Maybe

问题 I am running a single node swarm, I am using traefik to manage all my external connections, and I want to run a registry such that I can connect to it at registry.myhost.com Now all the examples I can see suggest creating a registry as a normal container rather than a service, however when I do this, I do not have the ability to add it to my traefik network and thus enable it to be found externally. Do I need to create another internal network and connect both traefik and it to it, and if so,

问题 What is the syntax to push an image to a private registry? From the documentation, I would expect the below to work: curl -X POST -i "http://localhost:2375/images/localhost:5000/oillio/my_app:1.0-SNAPSHOT/push" I can use the CLI to do this: docker push localhost:5000/oillio/my_app:1.0-SNAPSHOT This works fine. But I can't figure out what the syntax is to do this from the API. When I try the above, I get a status 500 response with the text "EOF" 回答1: The tag needs to be as a parameter and not

问题 I have a private Docker registry that is accessible at https://docker.somedomain.com (over standard port 443 not 5000). My infrastructure includes a set up of Mesosphere, which have docker containerizer enabled. I'm am trying to deploy a specific container to a Mesos slave via Marathon; however, this always fails with Mesos failing the task almost immediately with no data in stderr and stdout of that sandbox. I tried deploying from an image from the standard Docker Registry and it appears to

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 According to https://docs.docker.com/registry/spec/api/ I can call /v2/<name>/tags/list to get a list of the tags for a given image. It works fine, e.g.: {"name"=>"avi/test", "tags"=>["latest"]} However, I would like the digest for each tag. Yes, the "digest" is actually the hash of the manifest (at least as I best understood it from the API; not 100% clear). However, I would like a way of knowing what a unique identifier for "latest" (and every other tag) is. Use case: I might have someone
