Question

如何部署Docker应用程序而不将其发布到其集线器？我不想在他们的服务上创建用户名和密码（他们只是想在他们的生态系统中捕获苍蝇），我认为我不会使用Docker的 swarm 部分。除此之外，在公共存储库上发布您的闭源代码听起来非常不安全！但是我想看看它是如何工作的，并希望学习堆栈部分，这取决于 swarm 部分。我按照他们的教程，但应用程序仅部署在本地默认主节点上。

https://docs.docker.com/get-started/part4/#deploy-the-app-on-the-swarm-manager

docker-composer.yml

...
# replace username/repo:tag with your name and image details
image: friendlyhello

3个具有1个主节点的机器/节点

C:\Temp\docker-tutorial>docker-machine ls
NAME      ACTIVE   DRIVER       STATE     URL                         SWARM   DOCKER        ERRORS
default   *        virtualbox   Running   tcp://192.168.99.100:2376           v18.03.1-ce

myvm2     -        virtualbox   Running   tcp://192.168.99.102:2376           v18.03.1-ce

该应用程序部署了6个实例。

C:\Temp\docker-tutorial>docker service ls
ID                  NAME                MODE                REPLICAS            IMAGE                  PORTS

然而，应用程序仅落入默认主节点而没有任何群集节点。

C:\Temp\docker-tutorial>docker service ps getstartedlab_web

Docker版本18.03.0-ce，版本0520e24302，Windows 8.1

我试图关注

我在docker-compose.yml

中设置了这一行

但在我跑docker stack deploy之后，它仍然失败了！

图像位于“localhost”但不是192.168.99.100。

localhost:5000拒绝在浏览器中进行连接。我还尝试localhost:5000/get-started:part2作为图像名称，但也失败了。

您可以托管自己的docker容器注册表，也可以使用自定义身份验证的许多云提供商使用私有容器注册表。几个选项：

AWS ECR / Amazon Elastic Container Registry ：https://aws.amazon.com/ecr/
Azure容器注册表：https://azure.microsoft.com/en-us/services/container-registry/
Codefresh私人码头注册管理机构：https://codefresh.io/
Artifactory ：https://www.jfrog.com/confluence/display/RTF/Docker+Registry

如果您想要完全控制，您也可以托管自己的Docker Registry：

设置完注册后，您只需使用docker login进行身份验证，然后照常使用docker push/pull管理您的图片。
