Kubernetes kubectl create secret generic 命令详解

kubectl create secret generic

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
