Vagrant provision阶段kubectl连接localhost:8080失败，ssh执行正常

环境与操作步骤 #

• 使用Vagrant部署Kubernetes，基于对应的Vagrantfile模板
• 在node节点的provision配置段中，于node.vm.provision "shell", path: "scripts/node.sh"之后添加了自定义shell脚本配置：

  node.vm.provision "shell", path: "ecoemploi_scripts/ecoemploi-create.sh"
  

• 自定义脚本ecoemploi_scripts/ecoemploi-create.sh的内容如下：

  echo "Création du déploiement Kubernetes pour ecoemploi"
  kubectl apply -f ecoemploi-namespace.yaml
  kubectl apply -f ecoemploi-postgis-configmap.yaml
  kubectl apply -f ecoemploi-postgis-pv-pvclaim.yaml
  
  kubectl apply -f ecoemploi-postgis-sgbd.yaml
  kubectl apply -f ecoemploi-postgis-service.yaml
  

执行vagrant up时的错误 #

启动过程中node01节点输出以下错误：

node01: Création du déploiement Kubernetes pour ecoemploi
node01: The connection to the server localhost:8080 was refused - did you specify the right host or port?
node01: The connection to the server localhost:8080 was refused - did you specify the right host or port?
node01: The connection to the server localhost:8080 was refused - did you specify the right host or port?
node01: The connection to the server localhost:8080 was refused - did you specify the right host or port?
node01: The connection to the server localhost:8080 was refused - did you specify the right host or port?

手动执行命令正常 #

通过vagrant ssh node01登录节点后，手动执行相同命令可成功完成部署：

vagrant@worker-node01:~$ kubectl apply -f /vagrant/ecoemploi_scripts/ecoemploi-namespace.yaml
namespace/ecoemploi created
vagrant@worker-node01:~$ kubectl apply -f /vagrant/ecoemploi_scripts/ecoemploi-postgis-configmap.yaml

疑问 #

已尝试修改脚本中的文件路径为绝对路径或相对路径，但问题依旧。请问操作过程中哪里出现了错误？
