在docker registry配置了认证后, 项目中CICD中运行的test case失败, 错误日志如下

Caused by: org.testcontainers.containers.ContainerFetchException: Can't get Docker image: RemoteDockerImage(imageName=hub.fastonetech.com/cce/fastone-auditing:latest, imagePullPolicy=AlwaysPullPolicy(), imageNameSubstitutor=org.testcontainers.utility.ImageNameSubstitutor$LogWrappedImageNameSubstitutor@3b68a50c)

解决方案​

根据上述日志中的关键信息得出由于docker registry未认证导致该问题的出现

Caused by: com.github.dockerjava.api.exception.InternalServerErrorException: Status 500: {"message":"unauthorized: unauthorized to access repository: cce/fastone-auditing, action: pull: unauthorized to access repository: cce/fastone-auditing, action: pull"}

执行docker login命令，然后从~/.docker/config.json中获取认证信息作为DOCKER_AUTH_CONFIG环境变量的值

docker login -u <username> -p <password> <registry>
DOCKER_AUTH_CONFIG=""
DOCKER_AUTH_CONFIG=$(cat ~/.docker/config.json)
export DOCKER_AUTH_CONFIG
