外围资源类型存储卷，PV、PVC、SC、CSI(Longhorn)
非凡类型的插件:ConfigMap、Secret、downwardAPI
如何为容器化利用提供配置信息:
- 启动容器时, 间接向应用程序传递参数,args: []
- 将定义好的配置文件焙进镜像之中;
- 通过环境变量向容器传递配置数据: 有个前提要求，利用得反对从环境变量加载配置信息;
制作镜像时，应用 entrypoint 脚本来预处理变量，常见的做法就是应用非交互式编辑工具，将环境变量的值替换到利用的配置文件中; - 基于存储卷向容器传递配置文件;
运行中的扭转, 须要由应用程序重载;
ConfigMap 简介
ConfigMap API 资源用来保留 key-value pair 配置数据，这个数据能够在 pods 里应用，或者被用来为像 controller 一样的零碎组件存储配置数据。尽管 ConfigMap 跟 Secrets 相似，然而 ConfigMap 更不便的解决不含敏感信息的字符串。留神：ConfigMaps 不是属性配置文件的替代品。ConfigMaps 只是作为多个 properties 文件的援用。你能够把它了解为 Linux 零碎中的 /etc 目录，专门用来存储配置文件的目录。
ConfigMap 通过 env 环境变量援用
通过环境变量的配置容器化利用时，须要在容器配置段中嵌套应用 env 字段，它的值是一个由环境变量构建的列表。每个环项变量通常由 name 和 value(或 valueFron)字段形成
- name <string>: 环境变量的名称, 必选字段;
- value <string>: 环境变量的值，通过 $(VAR_NAME)援用，逃逸格局为“$$(VAR_NAME)” 默认值为空;
- valueFrom <object> ∶环境变量值的援用源，例如以后 Pod 资源的名称、名称空间、标签等，不能与非空值的 value 字段同时应用，即环境变量的值要么源于 value 字段，要么源于 valuFron 字段，二者不可同时提供数据。
- valueFron: 字段可援用的值有多种起源，包含以后 Pod 资源的属性值，容器相干的零碎资源配置、ConfigMap 对象中的 key 以及 Secret 对象中的 Key，它们别离要应用不同的嵌套字段进行定义。
- fieldRef <bject>: 以后 Pod 资源的指定字段，目前反对应用的字段包含 metadata.mime、metadata.namespce、metadata.labels、metadeta.annotations、spesc.nodeName、spec.serviceAccountName、status.hostIP 和 status.podIP 等;
- configMapKeyRef <Object>: ConfigMap 对象中的特定 Key;
- secretKeyRef<object>: Secret 对象中的特定 Key;
- resourceFieldRef <object>: 以后容器的特定系统资源的最小值(配额）或最大值《限额)，目前反对的援用包含 limits.cpu. limits.memory、limits.ephemeral-storage. requests.cpu、reuests.memory 和 requests.ephemeral-storage
[root@k8s-master ~]# kubectl create configmap --help #查看示例
...
Examples:
# Create a new configmap named my-config based on folder bar
kubectl create configmap my-config --from-file=path/to/bar
# Create a new configmap named my-config with specified keys instead of file basenames on disk
kubectl create configmap my-config --from-file=key1=/path/to/bar/file1.txt --from-file=key2=/path/to/bar/file2.txt
# Create a new configmap named my-config with key1=config1 and key2=config2
kubectl create configmap my-config --from-literal=key1=config1 --from-literal=key2=config2
# Create a new configmap named my-config from the key=value pairs in the file
kubectl create configmap my-config --from-file=path/to/bar
# Create a new configmap named my-config from an env file
kubectl create configmap my-config --from-env-file=path/to/bar.env
Options:
--allow-missing-template-keys=true: If true, ignore any errors in templates when a field or map key is missing in
