学习参照链接:https://www.cnblogs.com/caoxb/p/11243472.html
参照该链接,利用空闲的时间,花费快一周才部署成功,比较详细步骤参照该链接就好,此篇博客主要镜像相关遇到问题补充和记录。

虚拟机: VMware® Workstation 15 Pro15.5.0 build-14665864
操作系统:CentOS Linux release 7.5.1804 (Core)

  1. 部署环境时,需要用到3个虚拟机环境,所以可以装完第一个centos后,直接将装完的第一个centos硬克隆两个。
  2. 安装docker、安装kubectl、kubeadm、kubelet、cri-tools,需要进行相关yum源的准备,如果未准备好,会导致安装失败,
  3. yum源的准备:

  1. 在master节点安装kubectl、kubeadm、kubelet、cri-tools,
    1) 版本可以指定,但是有些时候,可能版本过老,会导致安装时,无法找到相关的包,可以不指定版本直接安装最新的即可
    2)安装时,需要指定参数 --nogpgcheck,不然会安装失败
    yum install -y kubectl-1.18.1-0.x86_64 --nogpgcheck
    yum install -y cri-tools-1.13.0-0.x86_64 --nogpgcheck
    yum install -y kubeadm-1.18.1-0.x86_64 --nogpgcheck
    yum install -y kubelet-1.18.1-0.x86_64 --nogpgcheck

  2. 在master执行kubeadm init初始化之前需要配置daemon.json,不然也会出现问题
    1)daemon.json的内容和路径
    [root@k8s-master docker]# cat /etc/docker/daemon.json
    {
    “exec-opts”: [“native.cgroupdriver=systemd”],
    “log-driver”: “json-file”,
    “log-opts”: {
    “max-size”: “100m”
    },
    “storage-driver”: “overlay2”,
    “registry-mirrors”:[
    “https://kfwkfulq.mirror.aliyuncs.com”,
    “https://2lqq34jg.mirror.aliyuncs.com”,
    “https://pee6w651.mirror.aliyuncs.com”,
    “http://hub-mirror.c.163.com”,
    “https://docker.mirrors.ustc.edu.cn”,
    “https://registry.docker-cn.com”
    ]
    }
    2)配置完毕后,执行
    systemctl daemon-reload
    systemctl restart docker

  3. master和node节点的kubectl等组件部署完毕后,需要在master部署CNI节点
    1)下载calico.yaml ,执行
    curl https://docs.projectcalico.org/manifests/calico.yaml -O
    kubectl apply -f calico.yaml
    2)如果下载不可用可以在下面链接查看最新的下载路径
    https://docs.projectcalico.org/getting-started/kubernetes/self-managed-onprem/onpremises

  4. 部署完毕后,执行kubectl get pods -n kube-system后,pod节点不是running状态
    1) CrashLoopBackOff 解释和解决–重启node节点的docker服务解决(问题解释pod反复产生拉起该容器,但是一值未拉起成功)
    2)ImagePullBackOff 去相关node节点手动拉取相关镜像文件(相关镜像拉取失败)
    例如:
    calico-node-6wfc5 0/1 Init:ImagePullBackOff
    使用kubectl describe pod -n kube-system calico-node-6wfc5
    查看,能够查看到是哪个node节点,哪个镜像,哪个版本拉取失败,执行docker pull 相关镜像,可以拉取下来

20210521重新通过kubeadm部署k8s遇到了新的问题,进行分享记录:

  1. kubeadm init 初始化失败,提示的错误信息如下:
[root@master kubelet.service.d]# kubeadm init --apiserver-advertise-address=192.168.229.149 --image-repository registry.aliyuncs.com/google_containers --kubernetes-version v1.21.1 --service-cidr=10.1.0.0/16 --pod-network-cidr=10.244.0.0/16

1.) 解决方法说明:因为昨天初始化的时候,已经将相关的images镜像已经下载到本地了,所以百度查询资料后,通过修改镜像的tag标志解决该问题,如下:

1) 镜像信息如下:
root@k82-master ~]# docker images

2) 通过kubeadm config images list 查看自己所安装kubelet所对应应该安装容器版本如下:
[root@k82-master ~]# kubeadm config images list
k8s.gcr.io/kube-apiserver:v1.21.1
k8s.gcr.io/kube-controller-manager:v1.21.1
k8s.gcr.io/kube-scheduler:v1.21.1
k8s.gcr.io/kube-proxy:v1.21.1
k8s.gcr.io/pause:3.4.1
k8s.gcr.io/etcd:3.4.13-0
k8s.gcr.io/coredns/coredns:v1.8.0
3) 通过修改docker images tag的方法来解决该问题(顺利解决)需要依次进行修改。修改完毕后,可以将阿里云的镜像进行删除,解除空间占用,不删除也不影响。
docker tag registry.aliyuncs.com/google_containers/kube-apiserver:v1.21.1  k8s.gcr.io/kube-apiserver:v1.21.1
4)  修改完毕后,镜像如下:
[root@k82-master ~]# docker images

  1. 进行kubeadm初始化,初始化成功,如下:
[root@k82-master ~]# kubeadm init --kubernetes-version=v1.21.1 --pod-network-cidr=10.244.0.0/16 --service-cidr=10.96.0.0/12 --ignore-preflight-errors=Swap
[init] Using Kubernetes version: v1.21.1
[preflight] Running pre-flight checks
	[WARNING Hostname]: hostname "k82-master" could not be reached
	[WARNING Hostname]: hostname "k82-master": lookup k82-master on 114.114.114.114:53: no such host
[preflight] Pulling images required for setting up a Kubernetes cluster
[preflight] This might take a minute or two, depending on the speed of your internet connection
[preflight] You can also perform this action in beforehand using 'kubeadm config images pull'
[certs] Using certificateDir folder "/etc/kubernetes/pki"

[addons] Applied essential addon: CoreDNS
[addons] Applied essential addon: kube-proxy

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 192.168.229.149:6443 --token fkdwsz.2mdicz8hpxo9bg3l \
	--discovery-token-ca-cert-hash sha256:1f457fc9ebef7a05be88acb6ad058b1b42f55ca57ace0c42b7aa05716b88d32c 

该问题解决方法,参考文章链接如下:

2) 问题原因: /etc/hosts文件中127.0.0.1和 localhostname的映射关系被我删除,导致该问题的出现,解决方法,在hosts文件中,加上映射关系,该问题解决。
[root@k82-master ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
