[英]How to mount the properties file in Kubernetes configmap using manifest yaml
I use minikube on windows 10 and try to test Kubernetes ConfigMap with both literal type and outer file type.我在 Windows 10 上使用 minikube,并尝试使用文字类型和外部文件类型测试 Kubernetes ConfigMap。 First I make below manifest yaml file to make ConfigMap.首先我在清单 yaml 文件下面制作 ConfigMap。
apiVersion: v1
kind: ConfigMap
metadata:
name: simple-config
data:
mysql_root_password: password
mysql_password: password
mysql_database: test
---
apiVersion: v1
kind: Pod
metadata:
name: blog-db
labels:
app: blog-mysql
spec:
containers:
- name: blog-mysql
image: mysql:latest
env:
- name: MYSQL_ROOT_PASSWORD
valueFrom:
configMapKeyRef:
name: simple-config
key: mysql_root_password
- name: MYSQL_PASSWORD
valueFrom:
configMapKeyRef:
name: simple-config
key: mysql_password
- name: MYSQL_DATABASE
valueFrom:
configMapKeyRef:
name: simple-config
key: mysql_database
ports:
- containerPort: 3306
The above configmap yaml file throws no errors.上面的 configmap yaml 文件不会引发任何错误。 It works successfully.它工作成功。 This time I try to test kubernetes configmap with file.这次我尝试用文件测试 kubernetes configmap。
== configmap.properties == configmap.properties
mysql_root_password=password
mysql_password=password
mysql_database=test
But I am stuck with this part.但我被这部分困住了。 Most of configmap examples use kubectl command with --from-file option like below,大多数 configmap 示例使用带有 --from-file 选项的 kubectl 命令,如下所示,
kubectl create configmap simple-config --from-file=configmap.properties
But I have no idea how to mount the properties file using manifest yaml file grammer.但我不知道如何使用清单 yaml 文件语法挂载属性文件。 Any advice?有什么建议吗?
You can not directly mount a properties file in a pod without first creating a ConfigMap from the properties file.You can create configMap from env file as below如果不先从属性文件创建 ConfigMap,就不能直接在 pod 中挂载属性文件。您可以从 env 文件创建 configMap,如下所示
kubectl create configmap simple-config \
--from-env-file=configmap.properties
