如何使用Jenkins自动将签名的Docker镜像推送到ACR？

问题描述

从自托管注册表移至ACR，并具有其他内容信任要求。 这是我的Jenkinsfile片段：

environment {
  DOCKER_CONTENT_TRUST=1
}
steps {
  docker.build("${env.IMAGE_NAME}")        # prevIoUsly generated,everything works here
  docker.withRegistry("${env.ACR_ENDPOINT",'credential-id')
    docker.image("${env.IMAGE_NAME}").push()
}

构建失败，并显示以下输出：

虽然仍然失败，但是图像被推送到ACR。 ACR已启用内容信任，IIRC将推送的图像限制为仅签名。 我如何解决此构建问题，同时仍然能够推送已签名的图像？ 预先感谢。
