我对Kubernetes很新,试图搞清楚。我还没有能够谷歌这个答案,所以我很难过。 Kubernetes可以将两个秘密安装到同一条路径上吗?说给出以下部署:
apiVersion: apps/v1 # for versions before 1.9.0 use apps/v1beta2
kind: Deployment
metadata:
name: nginx-deployment
labels:
app: nginx-deployment
version: v1
spec:
selector:
matchLabels:
app: nginx
replicas: 1
template:
metadata:
labels:
app: nginx
version: v1
spec:
volumes:
- name: nginxlocal
hostPath:
path: /srv/docker/nginx
- name: requestcert
secret:
secretName: requests-certificate
- name: mysitecert
secret:
secretName: mysitecert
containers:
- name: nginx
image: nginx:mainline-alpine # Use 1.15.0
volumeMounts:
- name: nginxlocal
subPath: config/nginx.conf
mountPath: /etc/nginx/nginx.conf
- name: requestcert
mountPath: /etc/nginx/ssl
- name: mysitecert
mountPath: /etc/nginx/ssl
- name: nginxlocal
subPath: logs
mountPath: /etc/nginx/logs
ports:
- containerPort: 443
是否可以将两个SSL证书挂载到同一目录(/ etc / nginx / ssl / *)?
如果没有,可以将TLS证书+密钥存储为"不透明"而不是kubernetes.io/tls类型的工作?我试图将两个证书+密钥组合成一个tls类型的秘密,但kubernetes期望它被称为tls.crt和tls.key,所以我不得不将它分成两个秘密文件。如果他们可以做为不透明,我想我可以删除两个秘密值,只使用一个不透明的条目。
谢谢!

是否可以将两个SSL证书挂载到同一目录(/ etc / nginx / ssl / *)?
不,因为(至少在使用docker运行时时)它使用的卷安装与mount -t ext4 /dev/something /path/something
的行为完全相同,因为/path/something
将是最后一次胜利。
但是,您只能使用温和的解决方法:将requestcert
挂载为/etc/nginx/.reqcert
(或类似),挂载mysitecert
为/etc/nginx/.sitecert
,然后取代图像的entrypoint
并将文件复制到位,然后再委派给实际的入口点:
containers:
- name: nginx
image: etc etc
command:
- bash
- -c
- |
mkdir -p /etc/nginx/ssl
cp /etc/nginx/.*cert/* /etc/nginx/ssl/
# or whatever initialization you'd like
# then whatever the entrypoint is for your image
/usr/local/sbin/nginx -g "daemon off;"
或者,如果这似乎不是一个好主意,您可以结合initContainers:
使用一次性Pod特定目录:
spec:
volumes:
# all the rest of them, as you had them
- name: temp-config
emptyDir: {}
initContainers:
- name: setup-config
image: busybox # or whatever
command:
- sh
- -c
- |
# "stage" all the config files, including certs
# into /nginx-config which will evaporate on Pod destruction
volumeMounts:
- name: temp-config
mountPath: /nginx-config
# and the rest
containers:
- name: nginx
# ...
volumeMounts:
- name: temp-config
mountPath: /etc/nginx
它们的复杂程度不同,取决于您是否需要处理跟踪上游图像的入口点命令,而不是保持上游图像不变,而是消耗更多的初始化能量
