docker-compose 将图像推送到注册表不起作用

Question

我有三个节点集群 - host01、host02、host03。
host01 是经理。

现在我在host01

撰写文件test.yml :

version: '3'                                           
services:                                              
  mongo:                                               
    image: ${PRIVATE_REGISTRY}/basin/mongo:3.0.15      
    restart: always                                    
    ports:                                             
      - 11081:27017                                    

  postgres:                                            
    image: ${PRIVATE_REGISTRY}/basin/postgres:10.1     
    restart: always                                    
    container_name: basin-postgres                               

${PRIVATE_REGISTRY} :

我在 5006 上发布注册表，而不是 5000

[root@host01 scripts]# echo ${PRIVATE_REGISTRY}    
host01:5006                                        

host01 上的 Docker 镜像:

/etc/docker/daemon.json :

[root@host01 scripts]# cat /etc/docker/daemon.json                                          
{"registry-mirrors": ["http://host01:5006"], "insecure-registries" : [ "host01:5006"] }     

docker-compose -f test.yml push什么也没打印，查询注册表显示什么都没有被推送:

[root@host01 scripts]# curl -X GET http://${PRIVATE_REGISTRY}/v2/_catalog    
{"repositories":[]}                                                          

但是 docker push ${PRIVATE_REGISTRY}/basin/mongo:3.0.15工作。

Answer 1

如果您查看 docker-compose push 的文档，有写:

Pushes images for services to their respective registry/repository.

The following assumptions are made:
You are pushing an image you have built locally.
You have access to the build key.

显然，您只能使用 docker-compose push 推送图像有 build:在他们的 docker-compose.yml 部分文件。添加一个为我解决了完全相同的问题。

看起来您实际上不必自己构建镜像 - 添加类似 build: . 的内容无需构建镜像(而是从 Docker Hub 或私有(private)注册表下载)似乎工作正常。
