Minikube ubuntu20.04從零安裝

首先說明一點，這裡安裝僅針對單機部署，并不會涉及多節點部署。是以如果想使用多個節點搭建k8s請不要參考此教程，首先展示一下本機基礎環境

[email protected]:~# cat /etc/os-release
NAME="Ubuntu"

ID_LIKE=debian
PRETTY_NAME="Ubuntu 20.04.2 LTS"

基礎工具安裝

1. 相關鏡像源配置

   這裡采用清華鏡像源，位址為 https://mirror.tuna.tsinghua.edu.cn/help/ubuntu/

   注意選擇目前Ubuntu對應的版本，之後将内容覆寫到

   /etc/apt/source.list

   檔案

   覆寫完成後執行指令

   apt-get update

2. 安裝curl

   apt-get install curl

3. 安裝contrack

   apt-get install conntrack

元件安裝

1. kubectl安裝

   curl -LO "https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/linux/amd64/kubectl"

   如果你ubuntu叢集無法執行這個指令，或者執行非常慢可以直接用能上外網主機通路上述網址，之後會自動下載下傳檔案，然後上傳到ubuntu主機，請确定下載下傳完成後繼續下面步驟

   将下載下傳檔案放到指定目錄，這個可以任意

[email protected]:/home/iris/k8s/kubectl# pwd
/home/iris/k8s/kubectl
           

之後配置環境變量，具體為修改/etc/profile檔案

[email protected]:~# tail -n 2 /etc/profile

export PATH=$PATH:/home/iris/k8s/kubectl:/home/iris/k8s/minikube

           

後面是minikube位置，可以先配置上

2. minikube安裝

curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64

同樣的，你也可以通過其他電腦下載下傳然後上傳至ubuntu主機，本次我的安裝位置如下

[email protected]:/home/iris/k8s/minikube# pwd
/home/iris/k8s/minikube
[email protected]:/home/iris/k8s/minikube# ll
total 58404
drwxr-xr-x 2 root root     4096 3月  27 23:59 ./
drwxr-xr-x 4 root root     4096 3月  27 23:58 ../
-rwxr-xr-x 1 root root 59794699 3月  27 23:58 minikube*
           

值得一提是下載下傳下的檔案名稱為

minikube-linux-amd64

，在檔案目錄下使用

mv minikube-linux-amd64 minikube

指令改為minikube

3. docker安裝

這一部分可以參考官方教程 https://docs.docker.com/engine/install/ubuntu/

本次使用

Install using the repository

開頭的安裝方式

啟動

啟動之前，使用指令

source /etc/profile

指令重新整理環境變量配置，之後執行如下指令

[email protected]:/home/iris/k8s# minikube start --vm-driver=none --image-repository=registry.cn-hangzhou.aliyuncs.com/google_containers
* minikube v1.18.1 on Ubuntu 20.04
* Using the none driver based on existing profile
* Starting control plane node minikube in cluster minikube
* Restarting existing none bare metal machine for "minikube" ...
* OS release is Ubuntu 20.04.2 LTS
* Preparing Kubernetes v1.20.2 on Docker 20.10.5 ...
  - kubelet.resolv-conf=/run/systemd/resolve/resolv.conf
    > kubelet.sha256: 64 B / 64 B [--------------------------] 100.00% ? p/s 0s
    > kubelet: 108.73 MiB / 108.73 MiB [-------------] 100.00% 4.35 MiB p/s 26s
  - Generating certificates and keys ...
  - Booting up control plane ...
  - Configuring RBAC rules ...
* Configuring local host environment ...
*
! The 'none' driver is designed for experts who need to integrate with an existing VM
* Most users should use the newer 'docker' driver instead, which does not require root!
* For more information, see: https://minikube.sigs.k8s.io/docs/reference/drivers/none/
*
! kubectl and minikube configuration will be stored in /root
! To use kubectl or minikube commands as your own user, you may need to relocate them. For example, to overwrite your own settings, run:
*
  - sudo mv /root/.kube /root/.minikube $HOME
  - sudo chown -R $USER $HOME/.kube $HOME/.minikube
*
* This can also be done automatically by setting the env var CHANGE_MINIKUBE_NONE_USER=true
* Verifying Kubernetes components...
  - Using image registry.cn-hangzhou.aliyuncs.com/google_containers/k8s-minikube/storage-provisioner:v4 (global image repository)
* Enabled addons: storage-provisioner, default-storageclass
* Done! kubectl is now configured to use "minikube" cluster and "default" namespace by default

           

配置到此結束
