在 Amazon Linux EC2 中安装 minikube kubernetes 时出错

Question

我正在尝试在 Amazon-linux EC2 实例中使用 mikikube 安装 kubernates。我正在关注https://github.com/aws-samples/aws-workshop-for-kubernetes/blob/master/03-path-application-development/301-local-development/readme.adoc#setup-on-ec2-if-you-do-not-virtualbox-on-your-laptop 的链接。 执行时出现以下错误

[ec2-user@ip-172-31-15-56 ~]$ minikube start --vm-driver=none
* minikube v1.4.0 on Amazon 2018.03
X The "none" driver requires root privileges. Please run minikube using 'sudo minikube --vm-driver=none'.
[ec2-user@ip-172-31-15-56 ~]$ sudo minikube start --vm-driver=none
sudo: minikube: command not found

也尝试在 root 用户下执行所有步骤，但错误相同 minikube: command not found。

谁能帮忙解决这个问题。

Answer 1

在用户权限中：

[ec2-user@ip-172-31-15-56 ~]$which minikube
/path/to/minikube

然后：

[ec2-user@ip-172-31-15-56 ~]$sudo /path/to/minikube --vm-driver=none

Answer 2

第一种方法是使用普通用户到 minikube 的完整路径：

[ec2-user@ip-172-31-43-207 ~]$ whereis minikube 
minikube: /usr/local/bin/minikube

[ec2-user@ip-172-31-43-207 ~]$ sudo /usr/local/bin/minikube start --vm-driver=none
?  minikube v1.4.0 on Amazon 2018.03 (xen/amd64)
?  Running on localhost (CPUs=2, Memory=3945MB, Disk=7997MB) ...

第二种方法是把你的二进制文件放到 root 的默认 bin 位置：

[ec2-user@ip-172-31-43-207 ~]$ sudo cp /usr/local/bin/minikube /usr/bin/
[ec2-user@ip-172-31-43-207 ~]$ sudo minikube version
minikube version: v1.4.0
commit: 7969c25a98a018b94ea87d949350f3271e9d64b6
[ec2-user@ip-172-31-43-207 ~]$ sudo minikube start --vm-driver=none
?  minikube v1.4.0 on Amazon 2018.03 (xen/amd64)
?  Running on localhost (CPUs=2, Memory=3945MB, Disk=7997MB) ...

关于 cmets 中的 docker 问题：理想情况下，下次这应该是单独的问题。

是的，已复制并收到与您相同的错误。

这是"Amazon Linux AMI 2018.03" 的问题：@Vin Odh 在Command not found: systemctl on Amazon Linux 2018.03 答案中明确指出。

Amazon Linux AMI 2018.03 是 systemd 不附带的“Amazon Linux 版本 1”，因此解决方案是简单地使用另一个正常工作的分配器，例如我没有问题

Ubuntu Server 16.04 LTS (HVM)


ubuntu@ip-172-31-40-246:~$ sudo minikube start --vm-driver=none
?  minikube v1.4.0 on Ubuntu 16.04 (xen/amd64)
?  Running on localhost (CPUs=2, Memory=3950MB, Disk=7876MB) ...
ℹ️   OS release is Ubuntu 16.04.6 LTS
?  Preparing Kubernetes v1.16.0 on Docker 18.09.7 ...
?  Downloading kubeadm v1.16.0
?  Downloading kubelet v1.16.0

⚠️  The 'none' driver provides limited isolation and may reduce system security and reliability.
⚠️  For more information, see:
?  https://minikube.sigs.k8s.io/docs/reference/drivers/none/

⚠️  kubectl and minikube configuration will be stored in /home/ubuntu
⚠️  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 /home/ubuntu/.kube /home/ubuntu/.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
⌛  Waiting for: apiserver proxy etcd scheduler controller dns
?  Done! kubectl is now configured to use "minikube"
