标签: minikube

我最近开始在Mac上本地使用Minikube学习Kubernetes.以前,我能够使用Minikube 0.10.0启动本地Kubernetes集群,创建部署并查看Kubernetes仪表板.

昨天我试图删除集群并从头开始重新做一切.但是,我发现无法部署资产,无法查看仪表板.从我看到的情况来看,在容器创建期间,一切似乎都被卡住了.

跑完之后minikube start,据报道

Starting local Kubernetes cluster...
Kubectl is now configured to use the cluster.

当我跑kubectl get pods --all-namespaces,它报告(注意STATUS列):

kubectl get pods --all-namespaces
NAMESPACE     NAME                          READY     STATUS              RESTARTS   AGE
kube-system   kube-addon-manager-minikube   0/1       ContainerCreating   0          51s

docker ps 没有显示:

docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES

minikube status 告诉我VM和集群正在运行:

minikubeVM: Running
localkube: Running

如果我尝试创建部署和自动规划器,我被告知它们已成功创建:

kubectl create -f configs
deployment "hello-minikube" created
horizontalpodautoscaler "hello-minikube-autoscaler" created

$ kubectl get pods --all-namespaces
NAMESPACE     NAME                             READY …

我是Kubernetes的新手,使用的是k8s v1.4,Minikube v0.15.0和Spotify maven Docker插件.
我的项目的构建过程创建了一个Docker镜像,并将其直接推送到Minikube的Docker引擎中.

pod是由我创建的部署(使用副本集)创建的,策略设置为type: RollingUpdate.

我在文档中看到了这个:

注意:当且仅当部署的pod模板(即.spec.template)发生更改时,才会触发Deployment的部署.

我正在寻找一种简单的方法/解决方法来自动化流程:构建触发>推送新的Docker镜像(更改版本)>部署将更新pod>服务将公开新的pod.

我目前正在尝试在Minikube上部署以下内容.我使用配置文件将主机路径用作minikube节点上的持久存储.

什么是等效的命令minikube delete在泊坞窗换桌面上OSX

据我了解,minikube创建了一个VM来托管其kubernetes集群,但我不明白docker-for-desktop如何在OSX上管理它.

我在本地使用 minikube。以下是.tf我用来创建 kubernetes 集群的文件：

provider "kubernetes" {
  config_path = "~/.kube/config"
}

resource "kubernetes_namespace" "tfs" {
  metadata {
    name = "tfs" # terraform-sandbox
  }
}

resource "kubernetes_deployment" "golang_webapp" {
  metadata {
    name      = "golang-webapp"
    namespace = "tfs"
    labels = {
      app = "webapp"
    }
  }
  spec {
    replicas = 3
    selector {
      match_labels = {
        app = "webapp"
      }
    }
    template {
      metadata {
        labels = {
          app = "webapp"
        }
      }
      spec {
        container {
          image             = "golang-docker-example" …

我用k8s版本1.5.2启动了minikube,我想降级我的kubectl,使它也是1.5.2.目前,当我跑步时, kubectl version我得到:

Client Version: version.Info{Major:"1", Minor:"7", GitVersion:"v1.7.5", GitCommit:"17d7182a7ccbb167074be7a87f0a68bd00d58d97", GitTreeState:"clean", BuildDate:"2017-08-31T19:32:12Z", GoVersion:"go1.9", Compiler:"gc", Platform:"darwin/amd64"}

我想使用kubectl来获取,PetSets但在以后的版本中,这已更新为StatefulSets所以我无法使用我当前的kubectl版本的命令

kubectl get petsets
the server doesn't have a resource type "petsets"

谢谢!

我是Kubernetes的初学者，并从本教程开始。我安装了VM，并期望能够通过使用以下命令来启动集群：

minikube start

但是我得到了错误：

Starting local Kubernetes v1.10.0 cluster...
Starting VM...
E0911 13:34:45.394430   41676 start.go:174] Error starting host: Error 
creating host: Error executing step: Creating VM.
: Error setting up host only network on machine start: The host-only 
adapter we just created is not visible. This is a well known 
VirtualBox bug. You might want to uninstall it and reinstall at least 
version 5.0.12 that is is supposed to fix this issue.

它说这是Virtualbox中一个众所周知的错误，但我安装了最新版本。有任何想法吗？

当我尝试将一个小文件复制到 Kubernetes pod 时，它失败并显示以下错误：

:~ $kubectl cp /tmp/a default/resolver-proxy-69dc786fcf-5rplg:/usr/local/bin/ --no-preserve=true
    tar: a: Cannot open: Permission denied
    tar: Exiting with failure status due to previous errors
    command terminated with exit code 2

有人可以帮我解决这个问题吗？我在 minikube 上运行 Kubernetes。

由于类似的错误，我还看到另一个 Postgres Pod 处于 Error 状态：

:~ $kubectl logs postgres-7676967946-7lp9g postgres
tar: /var/lib/postgresql/data: Cannot open: Permission denied
tar: Error is not recoverable: exiting now

我跑了minikube start --vm=true哪个输出：

  minikube v1.12.2 on Darwin 10.15.5

?  Your system has 16384MB memory but Docker has only 1991MB. For a better performance increase to at least 3GB.

我正在尝试在我的minikube中部署bitnami/mysql图表。我正在使用 Kubernetes v1.19、Minikube v1.17.1 和Helm 3

我创建了 PVC 和 PV，如下所示：

kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: mysql-pvc
spec:
  storageClassName: standard
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 3Gi
  selector:
    matchLabels:
      id: mysql-pv
----
kind: PersistentVolume
apiVersion: v1
metadata:
  name: mysql-pv
  labels:
    type: local
    id: mysql-pv
spec:
  storageClassName: standard
  capacity:
    storage: 8Gi
  accessModes:
    - ReadWriteOnce
  hostPath:
    path: /var/lib/mysql

/var/lib/mysql我通过以下方式创建了目录sudo mkdir -p /var/lib/mysql 这就是我创建 PVC 和 PC 的方式：

kubectl apply -f mysql-pv-dev.yaml
kubectl apply -f mysql-pvc-dev.yaml

这似乎有效： …
