如何在Minikube中使用本地docker镜像? [英] How to use local docker images with Minikube?

问题描述

我有几个要与minikube一起使用的docker映像.我不想先上传然后下载相同的图像，而不仅仅是直接使用本地图像.我该怎么做?

I have several docker images that I want to use with minikube. I don't want to first have to upload and then download the same image instead of just using the local image directly. How do I do this?

我尝试过的东西:
1.我尝试运行这些命令(分别两次删除minikube实例并重新开始)

Stuff I tried :
1. I tried running these commands (separately, deleting the instances of minikube both times and starting fresh)

kubectl run hdfs --image=fluxcapacitor/hdfs:latest --port=8989
kubectl run hdfs --image=fluxcapacitor/hdfs:latest --port=8989 imagePullPolicy=Never

输出:

NAME                    READY     STATUS              RESTARTS   AGE
hdfs-2425930030-q0sdl   0/1       ContainerCreating   0          10m

它只是停留在某些状态，但从未达到就绪状态.

It just gets stuck on some status but never reaches the ready state.

2.我尝试创建注册表，然后将图像放入其中，但这也不起作用.我可能做错了，但找不到正确的说明来完成此任务.

2. I tried creating a registry and then putting images into it but that didn't work either. I might've done that incorrectly but I can't find proper instructions to do this task.

请提供有关在本地kubernetes实例中使用本地docker映像的说明.

如果有人可以帮助我获得使用docker-compose做到这一点的解决方案，那就太好了.谢谢.

If someone could help me get a solution that uses docker-compose to do this, that'd be awesome. Thanks.

推荐答案

作为自述文件描述，您可以使用eval $(minikube docker-env)重用Minikube中的Docker守护程序.

As the README describes, you can reuse the Docker daemon from Minikube with eval $(minikube docker-env).

因此，要使用图片而不上传图片，可以按照以下步骤操作:

So to use an image without uploading it, you can follow these steps:

1. 使用eval $(minikube docker-env)
设置环境变量
2. 使用Minikube的Docker守护进程(例如docker build -t my-image .)构建映像
3. 在pod规范中将图像设置为build标签(例如my-image)
4. 将 imagePullPolicy 设置为Never，否则Kubernetes将尝试下载图像.

1. Set the environment variables with eval $(minikube docker-env)
2. Build the image with the Docker daemon of Minikube (eg docker build -t my-image .)
3. Set the image in the pod spec like the build tag (eg my-image)
4. Set the imagePullPolicy to Never, otherwise Kubernetes will try to download the image.

重要说明:，您必须在要使用的每个终端上运行eval $(minikube docker-env)，因为它仅设置当前shell会话的环境变量.

Important note: You have to run eval $(minikube docker-env) on each terminal you want to use, since it only sets the environment variables for the current shell session.
