Openshift和docker-我可以将哪个注册表用于Minishift？

Question

将Openshift用作容器即服务很容易，请参阅详细步骤。因此，通过Docker客户端，我可以使用Openshift。

我想使用Minishift在笔记本电脑上工作。那是笔记本电脑上Openshift的本地版本。

我应将哪个docker注册表与Minishift结合使用？Minishift没有自己的注册表-我想。

所以，我想做：

$ maven clean install -- building the application
$ oc login to your minishift environment
$ docker build -t myproject/mynewapplication:latest
$ docker tag -- ?? normally to a openshift docker registry entry
$ docker push -- ?? to a local docker registry?
$ on 1st time: $ oc new-app mynewapplication
$ on updates: $ oc rollout latest dc/mynewapplication-n myproject

Answer 1

我只使用docker，oc cluster up这非常相似。部署的内部注册表的地址在172.30.0.0/16空间（即默认服务网络）中。

$ oc login -u system:admin
$ oc get svc -n default  | grep registry
docker-registry   ClusterIP   172.30.1.1     <none>        5000/TCP                  14m

现在，此服务IP在群集内部，但是可以在路由器上公开：

$oc expose svc docker-registry -n default
$oc get route -n default  | grep registry
docker-registry   docker-registry-default.127.0.0.1.nip.io             docker-registry   5000-tcp                 None

在我的示例中，路线为 docker-registry-default.127.0.0.1.nip.io

通过此途径，您可以使用开发者帐户和令牌登录

$oc login -u developer
$docker login docker-registry-default.127.0.0.1.nip.io -p $(oc whoami -t) -u developer
Login Succeeded

注意： oc cluster up默认情况下是短暂的；文档可以提供有关如何使此设置持久化的说明。

还有一点需要注意的是，如果您希望OpenShift尝试使用某些本机生成器，则只需oc new-app . --name <appname>在源代码目录中运行即可。

$ cat Dockerfile 
FROM centos:latest

$ oc new-app . --name=app1
--> Found Docker image 49f7960 (5 days old) from Docker Hub for "centos:latest"

    * An image stream will be created as "centos:latest" that will track the source image
    * A Docker build using binary input will be created
      * The resulting image will be pushed to image stream "app1:latest"
      * A binary build was created, use 'start-build --from-dir' to trigger a new build
    * This image will be deployed in deployment config "app1"
    * The image does not expose any ports - if you want to load balance or send traffic to this component
      you will need to create a service with 'expose dc/app1 --port=[port]' later
    * WARNING: Image "centos:latest" runs as the 'root' user which may not be permitted by your cluster administrator
