Your Kubernetes control-plane has initialized successfully!
To start using your cluster, you need to run the following as a regular user:
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
Alternatively, if you are the root user, you can run:
export KUBECONFIG=/etc/kubernetes/admin.conf
You should now deploy a pod network to the cluster.
Run "kubectl apply -f [podnetwork].yaml" with one of the options listed at:
https://kubernetes.io/docs/concepts/cluster-administration/addons/
Then you can join any number of worker nodes by running the following on each as root:
kubeadm join 192.168.186.128:6443 --token 110vku.v2epdfhg15tzgar5 \
--discovery-token-ca-cert-hash sha256:6d748529131933e871bad4f03dfeca3aaba6bd9b257786acecba347f169ac155
[root@master ~]#
注意：
**kubeadm token create --print-join-command #重新生成token
kubeadm join 192.168.186.128:6443 --token 110vku.v2epdfhg15tzgar5 \

--control-plane
#注意 --control-plane是添加master节点的**
##只在master上执行
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
[root@master ~]# kubectl get nodes #缺少网络插件所以才是NotReady状态

description: "Ports is an optional field that restricts
the rule to only apply to traffic that has a source (destination)
port that matches one of these ranges/values. This value
is a list of integers or strings that represent ranges
of ports. \n Since only some protocols have ports, if
any ports are specified it requires the Protocol match
in the Rule to be set to \"TCP\" or \"UDP\"."

selector:
description: "Selector is an optional field that contains
a selector expression (see Policy for sample syntax).
\ Only traffic that originates from (terminates at) endpoints
matching the selector will be matched. \n Note that: in
addition to the negated version of the Selector (see NotSelector
below), the selector expression syntax itself supports
negation. The two types of negation are subtly different.
One negates the set of matched endpoints, the other negates
the whole match: \n \tSelector = \"!has(my_label)\" matches
packets that are from other Calico-controlled \tendpoints
that do not have the label \"my_label\". \n \tNotSelector
= \"has(my_label)\" matches packets that are not from
Calico-controlled \tendpoints that do have the label \"my_label\".
\n The effect is that the latter will accept packets from
non-Calico sources whereas the former is limited to packets
from Calico-controlled endpoints."

order:
description: Order is an optional field that specifies the order in
which the policy is applied. Policies with higher "order" are applied
after those with lower order. If the order is omitted, it may be
considered to be "infinite" - i.e. the policy will be applied last. Policies
with identical order will be applied in alphanumerical order based
on the Policy "Name".
type: number
selector:
description: "The selector is an expression used to pick pick out
the endpoints that the policy should be applied to. \n Selector
expressions follow this syntax: \n \tlabel == \"string_literal\"
\ -> comparison, e.g. my_label == \"foo bar\" \tlabel != \"string_literal\"
\ -> not equal; also matches if label is not present \tlabel in
{ \"a\", \"b\", \"c\", ... } -> true if the value of label X is
one of \"a\", \"b\", \"c\" \tlabel not in { \"a\", \"b\", \"c\",
... } -> true if the value of label X is not one of \"a\", \"b\",
\"c\" \thas(label_name) -> True if that label is present \t! expr
-> negation of expr \texpr && expr -> Short-circuit and \texpr
|| expr -> Short-circuit or \t( expr ) -> parens for grouping \tall()
or the empty selector -> matches all endpoints. \n Label names are
allowed to contain alphanumerics, -, _ and /. String literals are
more permissive but they do not support escape characters. \n Examples
(with made-up labels): \n \ttype == \"webserver\" && deployment
== \"prod\" \ttype in {\"frontend\", \"backend\"} \tdeployment !=
\"dev\" \t! has(label_name)"

types:
description: "Types indicates whether this policy applies to ingress,
or to egress, or to both. When not explicitly specified (and so
the value on creation is empty or nil), Calico defaults Types according
to what Ingress and Egress are present in the policy. The default
is: \n - [ PolicyTypeIngress ], if there are no Egress rules (including
the case where there are also no Ingress rules) \n - [ PolicyTypeEgress
], if there are Egress rules but no Ingress rules \n - [ PolicyTypeIngress,
PolicyTypeEgress ], if there are both Ingress and Egress rules.
\n When the policy is read back again, Types will always be one
of these values, never empty or nil."

到这里一个K8S集群就完整的部署好了，如果有其他的node节点操作方法是一样的，如果是高可用的,多个master可以给我留言，告诉你怎么操作。文章来源地址https://www.toymoban.com/news/detail-631926.html
到了这里，关于在线搭建K8S,kubernetes集群v1.23.9,docker支持的最后一个版本的文章就介绍完了。如果您还想了解更多内容，请在右上角搜索TOY模板网以前的文章或继续浏览下面的相关文章，希望大家以后多多支持TOY模板网！
