失败 – 需要身份validation才能从Dockerhubregistry中提取公共Docker镜像

我正在使用Jenkins自定义构build环境插件（1.6.5）从源容器中检查从属容器内的Dockerfile构build图像。 在Docker version 1.9.1, build ab77bde/1.9.1上运行的从站Docker version 1.9.1, build ab77bde/1.9.1

我的Dockerfile是下面这是能够从官方的Ubuntu的图像拉，但无法从官方node.js图像 –

 FROM node:boron # Create app directory RUN mkdir -p /usr/src/app WORKDIR /usr/src/app 

在jenkins的工作执行我得到失败 –

  $ docker build --file /data/name-jenkins/workspace/TestJobs/BuildFromSCM/Dockerfile /data/name-jenkins/workspace/TestJobs/BuildFromSCM Sending build context to Docker daemon 149.5 kB Sending build context to Docker daemon 149.5 kB Step 1 : FROM node:boron Trying to pull repository registry.access.redhat.com/node ... failed Trying to pull repository docker.io/library/node ... failed Authentication is required.

我能够在本地机器上构buildDocker镜像。 我确认，jenkins奴隶用户具有sudo权限。

Answer 1

我发现在我的奴隶机器上的.docker/config.json一个问题，我不小心设置了我的dockerhub证书，导致无法拉动我用来build立Jenkins工作的普通用户的公共图像。

 { "ServerURL": "https://index.docker.io/v1", "Username": "myusername", "Secret": "passw0rd1" } 

Answer 2

您可能需要docker-hub的证书，这是一个ca.crt文件放入：

 /etc/docker/certs.d/
