Functions

func Generate

func Generate(c *config.Config) error

Generate creates the kubeconfig for EKS

func ParseCloudConfig

func ParseCloudConfig(cloudConfig []byte, region string) (*clientcmdapi.Config, error)

ParseCloudConfig parses gzipped cloud-config formatted YAML from cloud-init As a kubelet kubeconfig file is provided we basically pull this out as-is from cloud-config but merge in our CA data as `certificate-authority-data` to save us having to write out a cert file.

func ParseShellScript

func ParseShellScript(userData string, region string) (*clientcmdapi.Config, error)

ParseShellScript parses shell-script format user-data seen on managed nodegroups

func ParseUserData

func ParseUserData(userData, region string) (*clientcmdapi.Config, error)

ParseUserData takes a string input metadata, works out its type and returns a *clientcmdapi.Config ready for marshalling to disk.

Types

type CloudConfig

type CloudConfig struct {
	WriteFiles []File `json:"write_files"`
}

CloudConfig contains the parsed cloud-config data

type EC2MetadataClient

type EC2MetadataClient struct {
	// contains filtered or unexported fields
}

EC2MetadataClient interface

func NewEC2MetadataClient

func NewEC2MetadataClient() (*EC2MetadataClient, error)

NewEC2MetadataClient instantiates an EC2 Metadata client

func (*EC2MetadataClient) GetUserData

func (c *EC2MetadataClient) GetUserData() (string, error)

GetUserData wraps the the AWS EC2 Metadata call This is all so we can mock it. There has to be a better way but the AWS Go SDK seems...a bit rubbish.

func (*EC2MetadataClient) Region

func (c *EC2MetadataClient) Region() (string, error)

Region wraps the the AWS EC2 Region call This is all so we can mock it. There has to be a better way but the AWS Go SDK seems...a bit rubbish.

type File

type File struct {
	Encoding    string `json:"encoding"`
	Content     string `json:"content"`
	Owner       string `json:"owner"`
	Path        string `json:"path"`
	Permissions string `json:"permissions"`
}
