我有一个要在ElasticBeanstalk上部署的多容器应用程序。以下是我的文件。

在本地系统上运行文件时,我可以工作。但是,当我将其上传到elasticbeanstalk上时,会出现以下错误。
ECS任务已停止,原因是:任务中的基本容器已退出。 (芹菜: db:cbeat:web:CannotPullContainerError:API错误(404):拉取权限 docker_test被拒绝,存储库不存在或可能需要 'docker login'redis:)
我使用container-transform将docker-compose.yml
转换为Dockerrun.aws.json
。对于上述文件,我的Dockerrun.aws.json
正在关注。

如何解决此问题?
答案 0 :(得分:2)
请将图像“ docker_test”推送到dockerhub或ECR,以便Beanstalk从中提取图像。目前,它在您的本地上,而ECS代理对此一无所知。
docker_test
图片标记并推送到dockerhub和ECR之类的注册表中。Dockerrun.aws.json
中的图片库URL。答案 1 :(得分:1)
我对EB并不熟悉,但是我对ECR和ECS相当熟悉。
当我尝试从ECR上的空存储库中提取图像时,通常会出现该错误,换句话说,已创建了ECR存储库,但您尚未将任何Docker映像推送到存储库。
当您尝试从ECR提取图像并且在标签中找不到图像的版本号时,也会发生这种情况。我建议您将docker-compose.yml文件更改为使用最新版本的图像。这意味着到处提及镜像docker_test的地方都需要在其后缀“:latest” 像这样:
image: docker_test:latest
我将在回复末尾发布我为您制作的整个docker-compose.yml。
我建议您看一下此文档:https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/create_deploy_docker.container.console.html请参阅“使用Amazon ECR存储库中的图像”部分,它们解释了如何解决docker登录问题。
我希望能有所帮助。如果对此有任何疑问,请回复。
