我有一个由脚本生成的自己的nginx配置/home/ubuntu/workspace/web.conf
。除了/etc/nginx/conf.d
default.conf
之下
以下是nginx.yaml
apiVersion: v1 kind: Pod metadata: name: nginx spec: volumes: - name: webconf hostPath: path: /home/ubuntu/workspace/web.conf containers: - image: nginx name: nginx ports: - containerPort: 18001 protocol: TCP volumeMounts: - mountPath: /etc/nginx/conf.d/web.conf name: web
虽然它仅映射为文件夹
$ kubectl create -f nginx.yaml pod "nginx" created $ kubectl exec -it nginx -- bash root@nginx:/app# ls -al /etc/nginx/conf.d/ total 12 drwxr-xr-x 1 root root 4096 Aug 3 12:27 . drwxr-xr-x 1 root root 4096 Aug 3 11:46 .. -rw-r--r-- 2 root root 1093 Jul 11 13:06 default.conf drwxr-xr-x 2 root root 0 Aug 3 11:46 web.conf
适用于泊坞容器-v hostfile:containerfile
。
我怎样才能在kubernetes中这样做?
顺便说一句:我在0.21.0
Ubuntu 16.04 LTS
上使用minikube kvm

尝试使用subPath
上的volumeMounts
键,如下所示:
apiVersion: v1
kind: Pod
metadata:
name: singlefile
spec:
containers:
- image: ubuntu
name: singlefiletest
command:
- /bin/bash
- -c
- ls -la /singlefile/ && cat /singlefile/hosts
volumeMounts:
- mountPath: /singlefile/hosts
name: etc
subPath: hosts
volumes:
- name: etc
hostPath:
path: /etc
示例:
$ kubectl apply -f singlefile.yaml
pod "singlefile" created
$ kubectl logs singlefile
total 24
drwxr-xr-x. 2 root root 4096 Aug 3 12:50 .
drwxr-xr-x. 1 root root 4096 Aug 3 12:50 ..
-rw-r--r--. 1 root root 1213 Apr 26 21:25 hosts
# /etc/hosts: Local Host Database
#
# This file describes a number of aliases-to-address mappings for the for

实际上它是由minikube使用的kvm
引起的。
path: /home/ubuntu/workspace/web.conf
如果我登录minikube,它是vm中的文件夹。
$ ls -al /home/ubuntu/workspace # in minikube host
total 12
drwxrwxr-x 2 ubuntu ubuntu 4096 Aug 3 12:11 .
drwxrwxr-x 5 ubuntu ubuntu 4096 Aug 3 19:28 ..
-rw-rw-r-- 1 ubuntu ubuntu 1184 Aug 3 12:11 web.conf
$ minikube ssh
$ ls -al /home/ubuntu/workspace # in minikube vm
total 0
drwxr-xr-x 3 root root 0 Aug 3 19:41 .
drwxr-xr-x 4 root root 0 Aug 3 19:41 ..
drwxr-xr-x 2 root root 0 Aug 3 19:41 web.conf
我不确切地知道为什么kvm主机文件夹代表这样共享。
因此,我使用minikube mount
命令,请参阅host_folder_mount.md,然后按预期工作。
