# kubectl create secret generic 命令详解
根据配置文件、目录或指定的 literal-value 创建 secret。
secret 可以保存为一个或多个 key/value 信息。
当基于配置文件创建 secret 时，key 将默认为文件的基础名称，value 默认为文件内容。如果基本名称的 key 无效，则可以指定另一个 key。
当基于目录创建 secret 时，key 还是文件的基础名称，目录中有效的 key 的每个文件都被打包到 secret 中，除了常规文件之外的任何目录条目都被忽略(例如 subdirectories, symlinks, devices, pipes, etc)。
# 语法
$ generic NAME [--type=string] [--from-file=[key=]source] [--from-literal=key1=value1] [--dry-run]
# 示例
使用指定的 keys 创建一个名为 my-secret 的 secret
kubectl create secret generic my-secret --from-file=ssh-privatekey=~/.ssh/id_rsa --from-file=ssh-publickey=~/.ssh/id_rsa.pub
用 key1 = supersecret 和 key2 = topsecret 创建一个名为 my-secret 的 secret
kubectl create secret generic my-secret --from-literal=key1=supersecret --from-literal=key2=topsecret
从 env 文件创建名为 my-secret 的 secret
kubectl create secret generic my-secret --from-env-file=path/to/bar.env
# Flags
| Name | Shorthand | Default | Usage |
|---|---|---|---|
| allow-missing-template-keys | true | If true, ignore any errors in templates when a field or map key is missing in the template. Only applies to golang and jsonpath output formats. | |
| dry-run | false | If true, only print the object that would be sent, without sending it. | |
| from-env-file | Specify the path to a file to read lines of key=val pairs to create a secret (i.e. a Docker .env file). | ||
| from-file | [] | Key files can be specified using their file path, in which case a default name will be given to them, or optionally with a name and file path, in which case the given name will be used. Specifying a directory will iterate each named file in the directory that is a valid secret key. | |
| from-literal | [] | Specify a key and literal value to insert in secret (i.e. mykey=somevalue) | |
| generator | secret/v1 | The name of the API generator to use. | |
| no-headers | false | When using the default or custom-column output format, don't print headers (default print headers). | |
| output | o | Output format. One of: json|yaml|wide|name|custom-columns=...|custom-columns-file=...|go-template=...|go-template-file=...|jsonpath=...|jsonpath-file=... See custom columns [http://kubernetes.io/docs/user-guide/kubectl-overview/#custom-columns], golang template [http://golang.org/pkg/text/template/#pkg-overview] and jsonpath template [http://kubernetes.io/docs/user-guide/jsonpath]. | |
| output-version | DEPRECATED: To use a specific API version, fully-qualify the resource, version, and group (for example: 'jobs.v1.batch/myjob'). | ||
| save-config | false | If true, the configuration of current object will be saved in its annotation. Otherwise, the annotation will be unchanged. This flag is useful when you want to perform kubectl apply on this object in the future. | |
| schema-cache-dir | ~/.kube/schema | If non-empty, load/store cached API schemas in this directory, default is '$HOME/.kube/schema' | |
| show-all | a | false | When printing, show all resources (default hide terminated pods.) |
| show-labels | false | When printing, show all labels as the last column (default hide labels column) | |
| sort-by | If non-empty, sort list types using this field specification. The field specification is expressed as a JSONPath expression (e.g. '{.metadata.name}'). The field in the API resource specified by this JSONPath expression must be an integer or a string. | ||
| template | Template string or path to template file to use when -o=go-template, -o=go-template-file. The template format is golang templates [http://golang.org/pkg/text/template/#pkg-overview]. | ||
| type | The type of secret to create | ||
| validate | true | If true, use a schema to validate the input before sending it |
