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=...

kubectl create secret docker-registry

创建与Docker registries一起使用的secret。

Dockercfg secrets用于对Docker registries进行安全认证。

当使用Docker命令push镜像时，可以进行Docker registries认证

$ docker login DOCKER_REGISTRY_SERVER --username=DOCKER_USER --password=DOCKER_PASSWORD --email=DOCKER_EMAIL'.

这时会产生一个 ~/.dockercfg 文件，在“docker push”和“docker pull”命令时，此文件用于registries进行认证。

在创建应用时，当Node节点从私有仓库Pull镜像时，需要有相应凭证，才能使用私有Docker仓库。我们可以通过创建dockercfg secret并添加到service account来实现。

语法

$ docker-registry NAME --docker-username=user --docker-password=password --docker-email=email [--docker-server=string] [--from-literal=key1=value1] [--dry-run]

示例

如果没有.dockercfg 文件，则可以使用以下命令创建dockercfg secret：

kubectl create secret docker-registry my-secret --docker-server=DOCKER_REGISTRY_SERVER --docker-username=DOCKER_USER --docker-password=DOCKER_PASSWORD --docker-email=DOCKER_EMAIL
