.Net Core3.x部署到阿里云ACK中

前面，我使用自己的服务器基于Docker部署了core程序，现在我们来使用一下新的方法，将我们的程序发布到阿里云ACK中，如果是IDEA的话，可以使用Alibaba Cloud Toolkit实现快速部署，但是现在仅支持IntelliJ IDEA、Eclipse、PyCharm 以及其他、Mave，不过据说VS CODE快要来了。那么现在我们暂时就先手动来操作一番吧

发布Core程序

我习惯使用命令方式:

dotnet publish -r linux-x64 -o ./bin/output -c release

具体命令说明详见https://docs.microsoft.com/zh-cn/dotnet/core/tools/dotnet-publish?tabs=netcore21,其中的RID也比较重要，大家也需要了解一下.我们开始编写Dockerfile:

FROM mcr.microsoft.com/dotnet/core/runtime:3.1
WORKDIR /app
EXPOSE 80
EXPOSE 443
COPY [".", "."]
ENTRYPOINT ["dotnet", "Web.dll"]

开始构建：

[root@instance-p0a4erj8 core]# docker build -t core3.x-swagger -f Dockerfile .

运行我们的镜像:

docker run --name swagger -d -p 80:80 core3.x-swagger

可以看到我们的容器已经启动好了。

[root@instance-p0a4erj8 ~]# docker ps -a
CONTAINER ID        IMAGE                                             COMMAND                  CREATED              STATUS                PORTS                                          NAMES

可以查看一下日志:

[root@instance-p0a4erj8 ~]# docker logs eb38557539a9

      Now listening on: http://[::]:80

访问也是正常.
好，接下来，我们就上传到阿里的ACR上面。
先去https://cr.console.aliyun.com进行设置.首先需要提示设置密码.设置完后，会跳转到创建仓库页面


创建完成后，我们就开始登陆到ACR

[root@instance-p0a4erj8 ~]#  docker login --username=xxxxxx registry.cn-hangzhou.aliyuncs.com
Password: 
WARNING! Your password will be stored unencrypted in /root/.docker/config.json.
Configure a credential helper to remove this warning. See
https://docs.docker.com/engine/reference/commandline/login/#credentials-store

Login Succeeded

推送镜像

 docker tag [ImageId] registry.cn-hangzhou.aliyuncs.com/52fx/52fx:[镜像版本号]
 docker push registry.cn-hangzhou.aliyuncs.com/52fx/52fx:[镜像版本号]

 示例:
[root@instance-p0a4erj8 ~]# docker tag core3.x-swagger registry.cn-hangzhou.aliyuncs.com/52fx/52fx:1.0
[root@instance-p0a4erj8 ~]# docker push registry.cn-hangzhou.aliyuncs.com/52fx/52fx:1.0
The push refers to repository [registry.cn-hangzhou.aliyuncs.com/52fx/52fx]

部署镜像

创建K8S集群，需要创建一个专有网络

需要开通两个授权的权限

创建成功后需要耐心的等待几分钟

接下来就是部署镜像,全是界面操作。



创建好Service->Ingress就可以访问了

service:

apiVersion: v1
kind: Service
metadata:
  creationTimestamp: '2019-12-14T03:28:23Z'
  name: net
  namespace: default
  resourceVersion: '19318673'
  selfLink: /api/v1/namespaces/default/services/net
  uid: c8ba0fb3-1e21-11ea-9a91-9e68548c9b68
spec:
  clusterIP: None
  ports:
    - name: http
      port: 80
      protocol: TCP
      targetPort: 80
  selector:
    app: 52fx-default
  sessionAffinity: None
  type: ClusterIP
status:
  loadBalancer: {}

Ingress：

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  annotations:
    nginx.ingress.kubernetes.io/service-weight: 'net: 100'
  creationTimestamp: '2019-12-14T03:33:32Z'
  generation: 1
  name: 52fx
  namespace: default
  resourceVersion: '19338000'
  selfLink: /apis/extensions/v1beta1/namespaces/default/ingresses/52fx
  uid: 80bd156a-1e22-11ea-9a91-9e68548c9b68
spec:
  rules:
    - http:
        paths:
          - backend:
              serviceName: net
              servicePort: 80
            path: /
status:
  loadBalancer:
    ingress:
      - ip: 39.105.240.144

后面，我们再详细了解一下k8s的相关配置
