如何从 snap 包运行 kubectl？

举例来说：

$ sudo snap install kubectl --classic;
$ kubectl cluster-info dump;
The connection to the server localhost:8080 was refused - did you specify the right host or port?
$ ps -aux | grep kube;
$ lsb_release -a;
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 20.04.2 LTS
Release:    20.04
Codename:   focal

需要安装其他包或服务吗？我尝试安装kubeadm：

$ sudo snap install kubeadm --classic;
$ sudo kubeadm init;
[init] Using Kubernetes version: v1.20.4
[preflight] Running pre-flight checks
    [WARNING Service-Docker]: docker service is not enabled, please run 'systemctl enable docker.service'
...
$ sudo snap services;
Servicio        Encendido  Actual    Notas
docker.dockerd  activado   activo    -
kubelet.daemon  activado   inactivo  -
$ sudo docker --version
Docker version 19.03.13, build cd8016b6bc

答案1

编辑 /etc/systemd/system/snap.docker.dockerd.service（或其他 snap docker 服务位置）添加以下行：

[Install]
Alias=docker.service

然后运行：

sudo systemctl reenable snap.docker.dockerd.service
sudo systemctl daemon-reload
sudo systemctl restart snap.docker.dockerd.service

就我而言，它起作用了。
