Answer 1

我最近遇到了同样的错误。发生这种情况是因为您需要指定版本。

IE：docker pull envoyproxy/envoy:v1.18.3

如果你尝试这样做：

docker pull envoyproxy/envoy

您遇到了以下问题：

Error response from daemon: manifest for envoyproxy/envoy:latest not found: manifest unknown: manifest unknown

Answer 2

它通常发生在本地计算机上或您要查找的注册表中不存在图像时。

假设我有一个名为repository-name/image-name:v1.0.0 的图像

对于以下 docker-compose.yaml

    # an example of docker compose
    version: '2'
    services:
      my-service-name:
        image: repository-name/image-name:v1.0.0
        restart: always

在两种情况下尝试使用存储在dockerhub上的docker图像时，我遇到了同样的错误：

当我输入错误的图像名称时。

    # a wrong example
    version: '2'
    services:
      my-service-name:
        image: repository-name/image-wrong-name:v1.0.0
        restart: always

命令“docker-compose up”，返回错误：

    /usr/bin/docker-compose up -d

    Pulling my-service-name (repository-name/image-wrong-name:v1.0.0)...
    ERROR: manifest for repository-name/image-wrong-name:v1.0.0 not found: manifest unknown: manifest unknown

或者如果图像的版本不存在。

    # a wrong example
    version: '2'
    services:
      my-service-name:
        image: repository-name/image-name:v1.0.1
        restart: always

我有同样的错误：

    /usr/bin/docker-compose up -d

    Pulling my-service-name (repository-name/image-name:v1.0.1)...
    ERROR: manifest for repository-name/image-name:v1.0.1 not found: manifest unknown: manifest unknown
