Docker Compose不允许使用本地映像 [英] Docker Compose does not allow to use local images

问题描述

以下命令失败，尝试从Docker Hub中提取图像：

The following command fails, trying to pull image from the Docker Hub:

$ docker-compose up -d
Pulling web-server (web-server:staging)...
ERROR: repository web-server not found: does not exist or no pull access

但是我只想使用图像的本地版本，该版本存在：

But I just want to use a local version of the image, which exists:

$ docker images
REPOSITORY           TAG                 IMAGE ID            CREATED             SIZE
web-server           staging             b94573990687        7 hours ago         365MB

为什么Docker不在本地存储的映像中搜索？

Why Docker doesn't search among locally stored images?

这是我的Docker Compose文件：

This is my Docker Compose file:

version: '3'
services:
  chat-server:
    image: chat-server:staging
    ports:
      - "8110:8110"
  web-server:
    image: web-server:staging
    ports:
      - "80:80"
      - "443:443"
      - "8009:8009"
      - "8443:8443"

和我的。环保文件：

DOCKER_HOST=tcp://***.***.**.**:2376
DOCKER_TLS_VERIFY=true 
DOCKER_CERT_PATH=/Users/Victor/Documents/Development/projects/.../target/docker

推荐答案

通常，这应该按照您的描述进行工作。试图重现它，但它确实起作用了……

In general, this should work as you describe it. Tried to reproduce it, but it simply worked...

文件夹结构：

.
├── docker-compose.yml
└── Dockerfile

内容的Dockerfile：

Content of Dockerfile:

FROM alpine
CMD ["echo", "i am groot"]

构建并标记图像：

docker build -t groot .
docker tag groot:latest groot:staging

与docker-compose.yml：

with docker-compose.yml:

version: '3.1'
services:
  groot:
    image: groot:staging

并启动docker-compose：

and start docker-compose:

$ docker-compose up
Creating groot_groot ... 
Creating groot_groot_1 ... done
Attaching to groot_groot_1
groot_1  | i am groot
groot_groot_1 exited with code 0
