Question

当尝试将我的自定义nginx映像从本地注册表部署到kubernetes时，我在kubernetes-dashboard中看到以下错误-

无法拉取映像“ myapp”：rpc错误：代码=未知desc =来自守护程序的错误响应：找不到存储库myapp：不存在或没有拉取访问权限

这是我遵循的步骤-

1) Built my customer image using docker
2) kubectl run myapp --image=myapp --port=80 --image-pull-policy=IfNotPresent
3) kubectl expose deployment myapp --type=LoadBalancer --port=80 --target-port=80 --name=myapp

在Kubernetes-dashboard中，由于未找到存储库myapp错误，我看到部署显示失败。

我什至尝试添加https://kubernetes.io/docs/tasks/configure-pod-container/pull-image-private-registry/

中提到的步骤

docker login
kubectl create secret docker-registry regcred --docker-server=https://index.docker.io/v1/ --docker-username=xxx --docker-password=xxx --docker-email=xxx

但还是同样的问题。

我应该怎么做才能在GKE中获得本地仓库。感谢任何帮助。谢谢。

这里的问题是您的吊舱正在工作节点上，并且工作节点上没有import matplotlib.pyplot as plt import numpy as np import matplotlib.animation as animation def update_fig(num, data, plot, ax) : text = None if num % 2 == 0 : text = ax.text(0.5, 0.5, str(num), horizontalalignment='center', verticalalignment='center', transform=ax.transAxes,size=15) plot.set_array(data[:, :, num %1500].ravel()) if text : return pp_color, text, else : return pp_color, fig, ax = plt.subplots() data = np.random.rand(60, 50, 1500) pp_color = plt.pcolormesh(data[:,:, 0], cmap = 'Reds', vmin=np.amin(data), vmax=np.amax(data)) cbar = plt.colorbar() t1 = cbar.ax.set_title('t1') plt.axis('equal') ax.text(0.5, -0.1, 'footnote text', horizontalalignment='center', transform=ax.transAxes,) t2 = ax.set_title("t2") line_ani = animation.FuncAnimation(fig, update_fig, interval=0.1, blit=True, fargs=(data, pp_color, ax)) plt.show()图片。

您需要按如下方式将mynginx映像从主节点复制到工作节点：

在主节点上运行以下命令：

mynginx

现在将生成的tar文件复制到工作节点并使用以下命令加载该图像：

docker save -o <path for generated tar file> mynginx

这会将docker load -i <path to image tar file>图片加载到您的工作节点上，并且可以解决您的问题
