将 docker 镜像推送到亚马逊 ecs 存储库 [英] Push docker image to amazon ecs repository
问题描述
我是 AWS 新手.我想在 AWS ECS 容器实例上设置一个私有 docker 存储库.我创建了一个名为 name 的存储库.AWS 显示的示例推送命令正在运行.
Im new to AWS. I want to set up a private docker repository on an AWS ECS container instance. I created a repository named name. The example push commands shown by AWS are working.
aws ecr get-login --region us-west-2
docker build -t name .
docker tag name:latest ############.dkr.ecr.us-west-2.amazonaws.com/name:latest
docker push ############.dkr.ecr.us-west-2.amazonaws.com/name:latest
但是通过这些命令，我构建并推送了一个名为 name 的图像，并且我想构建一个名为 foo 的图像.所以我将命令更改为:
But with this commands I build and pushed an image named name and I want to build an image named foo. So I altered the commands to:
docker build -t foo .
docker tag foo ###########.dkr.ecr.us-west-2.amazonaws.com/name/foo
docker push ###########.dkr.ecr.us-west-2.amazonaws.com/name/foo
这应该有效，但它没有.经过一段时间的重试后，我得到了错误:
This should work, but it doesn't. After a period of retrys I get the error:
The push refers to a repository [###########.dkr.ecr.us-west-2.amazonaws.com/name/foo]
8cc63cf4528f: Retrying in 1 second
...
name unknown: The repository with name 'name/foo' does not exist in the registry with id '############'
AWS 是否真的需要为我要推送的每张图片使用一个专用存储库?
Does AWS really require a dedicated repository for every image i want to push?
推荐答案
EC2 容器注册表 需要 映像存储库 为要发布到注册表的每个图像名称"或名称空间/名称"进行设置.
The EC2 Container Registry requires an image Repository to be setup for each image "name" or "namespace/name" you want to publish to the registry.
您可以在每个存储库中发布您想要的任何 :tags(默认限制为 100 个标签).
You can publish any :tags you want in each Repository though (The default limit is 100 tags).
我在 AWS 文档中没有看到任何地方专门说明存储库 -> 图像名称映射，但 创建存储库 - ECR 用户指南中的第 6d 节
I haven't seen anywhere in the AWS documentation that specifically states the repository -> image name mapping but it's implied by Creating a Repository - Section 6d in the ECR User Guide
Docker Image 规范包括存储库的定义
存储库
在一个公共前缀(: 之前的名称组件)下分组的标签集合.例如，在带有名称标记的图像中my-app:3.1.4，my-app 是Repository 组件的名字.一个存储库名称由斜杠分隔的名称组成，可选地以 DNS 主机名作为前缀.主机名必须符合标准 DNS 规则，但不能包含 _ 字符.如果主机名是存在，它可以可选地后跟一个端口号，格式为:8080.名称组件可能包含小写字符、数字和分隔符.分隔符定义为句点，一个或两个下划线或一个或多个破折号.名称组件可能无法启动或以分隔符结尾.
A collection of tags grouped under a common prefix (the name component before :). For example, in an image tagged with the name
my-app:3.1.4, my-app is the Repository component of the name. A
repository name is made up of slash-separated name components,
optionally prefixed by a DNS hostname. The hostname must comply with
standard DNS rules, but may not contain _ characters. If a hostname is
present, it may optionally be followed by a port number in the format
:8080. Name components may contain lowercase characters, digits, and
separators. A separator is defined as a period, one or two
underscores, or one or more dashes. A name component may not start or
end with a separator.
