Kubernetes
kubernetes 之网络(canal)
本文主要是介绍kubernetes 之网络(canal)，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！
https://kubernetes.io/docs/setup/production-environment/tools/kubeadm/create-cluster-kubeadm/
所有节点重设，快速销毁集群。镜像之类的还是在的
echo y|kubeadm reset
kubeadm init --apiserver-advertise-address 10.0.0.4 --pod-network-cidr=10.244.0.0/16 --image-repository=registry.aliyuncs.com/google_containers

参考它，得到部署文件，但是文件有问题https://www.cnblogs.com/dribs/p/10318936.html
参考它和报错信息修改文件，https://www.cnblogs.com/dudu/p/14494823.html
修改1
#将beta1都去掉 因为no matches for kind "CustomResourceDefinition" in version "apiextensions.k8s.io/v1beta1"
sed -i "s#beta1##g" canal.yaml
修改2、
将DaemonSet的extensions/v1beta1改为apps/v1。因为报错：no matches for kind "DaemonSet" in version "extensions/v1beta1"
kind: DaemonSet
apiVersion: apps/v1
修改3、报错不识别的version,把version：v1去掉。报错显示缺少，versions,根据修改2做了修改
修改4、一步步添加 versions:- name: v1 served: true storage: true schema:这几个属性，还是得一样，
经确认，文件缺少如下：
versions:
- name: v1
# Each version can be enabled/disabled by Served flag.
served: true
# One and only one version must be marked as the storage version.
storage: true
schema:
openAPIV3Schema:
type: object
properties:
spec:
type: object
properties:
title:
type: string
url:
type: string
publishdate:
type: string
body:
type: string
博客中是下面这样写的：
CRD(Custom Resource Definition) 是 kubernetes 强大扩展能力的一处体现，联系到编程场景，CRD 相当于是类(class)，custom resource 相当于是对象或者实例，通过 CRD 可以创建自己定义的资源类型，api server 会直接支持，可以通过 kubectl 命令创建对应的资源并对资源进行删/查/改的操作，资源对象会被保存在 etcd 中，可以像操作 pod 那样操作自己创建的 resouce。
这篇随笔以发布博文场景为例体验一下 kubernetes 的 CRD，对应的 custom resource 就是 BlogPost。
首先，编写 BlogPost 的 CRD 清单文件 blogpost-crd.yaml，给 BlogPost 定义了3个属性：title, pushishdate, body，从编程角度就是创建了一个 BlogPost 类
apiVersion: apiextensions.k8s.io/v1
kind: CustomResourceDefinition
metadata:
name: blogposts.kube.cnblogs.com
spec:
group: kube.cnblogs.com
scope: Namespaced
names:
kind: BlogPost
singular: blogpost
plural: blogposts
listKind: BlogPostList
versions:
- name: v1
# Each version can be enabled/disabled by Served flag.
served: true
# One and only one version must be marked as the storage version.
storage: true
schema:
openAPIV3Schema:
type: object
properties:
spec:
type: object
properties:
title:
type: string
url:
type: string
publishdate:
type: string
body:
type: string
编写清单注意事项：
metadata.name 是 spec.names.plural + "." + spec. group 的组合，如果写 blogposts.kube.cnblogs.com，会包下面的错误 metadata.name: Invalid value: "blogpost.kube.cnblogs.com": must be spec.names.plural+"."+spec.group
scope 有2种，一种是 Cluster，一种是 Namespaced，比如 node 资源的 scope 是 Cluster，pod 资源的 scope 是 Namespaced，Cluster 资源的 url 路径是 /clusters/{cluster}/{plural}，Namespaced 资源的 url 路径是 /clusters/{cluster}/namespaces/{namespace}/{plural}
属性不支持日期类型，只支持 "array", "boolean", "integer", "number", "object", "string" 五种类型。
然后，基于清单文件创建 CRD
修改完后部署上了，然后将其它两个节点加入集群。但是pod有点问题，没有都running，
