[英]How to mount configuration files into a Kubernetes Pod?
I have a postgres instance that I generally spin up using a docker-compose.yml
file.我有一个 postgres 实例,我通常使用
docker-compose.yml
文件启动它。 It mounts some configuration files like this:它会像这样挂载一些配置文件:
volumes:
- postgres-volume:/var/lib/postgresql/data
- ./postgresql.conf:/etc/postgresql.conf
- ./logs:/logs
- ./pg_hba.conf:/etc/pg_hba.conf
These files are located in the same folder as the docker-compose.yml
file is.这些文件与
docker-compose.yml
文件位于同一文件夹中。
My question is: how do I make a Pod that contains this container also mount these configuration files?我的问题是:如何使包含此容器的 Pod 也挂载这些配置文件? I read something about PVC in Kube.netes but I'm having a hard time connecting the dots and going from the docker-compose way of thinking to the Kube.netes way of thinking.
我在 Kube.netes 上读到了一些关于 PVC 的内容,但我很难把这些点联系起来,也很难从 docker-compose 的思维方式转向 Kube.netes 的思维方式。
Any help is greatly appreciated.任何帮助是极大的赞赏。
Easiest approach would be to store the files in a ConfigMap
and mount those as volumes in the container.最简单的方法是将文件存储在
ConfigMap
中,并将它们作为卷挂载到容器中。
apiVersion: v1
kind: ConfigMap
metadata:
name: my-config
data:
my.properties: |
url=example.com
username=username
password=password
index.html: |
Hello world
[...]
containers:
- name: my-container
image: some-registry/some-image
volumeMounts:
- name: config-volume
mountPath: /etc/config/my.properties
subPath: my.properties
- name: config-volume
mountPath: /some/different/path/index.html
subPath: index.html
volumes:
- name: config-volume
configMap:
name: my-config
[...]
By that the my.properties
file is mounted into /etc/config
and index.html
into /some/different/path
of the my-container
file system.通过这种方式,
my.properties
文件被挂载到/etc/config
和index.html
到my-container
文件系统的/some/different/path
中。
You can also generate the configmap from the file by kubectl create configmap my-config --from-file /path/to/my.properties --from-file /path/to/index.html
您还可以通过
kubectl create configmap my-config --from-file /path/to/my.properties --from-file /path/to/index.html
从文件生成 configmap
