DefaultSSHTemplates contains the configuration of default templates used on ssh. Relative paths are relative to the StepPath.

Functions

func LoadAll 

func LoadAll(t *Templates) (err error)

LoadAll preloads all templates in memory. It returns an error if an error is found parsing at least one template.

Types

type Output 

type Output struct {
	Name    string       `json:"name"`
	Type    TemplateType `json:"type"`
	Path    string       `json:"path"`
	Comment string       `json:"comment"`
	Content []byte       `json:"content"`
}

Output represents the text representation of a rendered template.

func (*Output) Write 

func (o *Output) Write() error

Write writes the Output to the filesystem as a directory, file or snippet.

type SSHTemplates 

type SSHTemplates struct {
	User []Template `json:"user"`
	Host []Template `json:"host"`
}

SSHTemplates contains the templates defining ssh configuration files.

func (*SSHTemplates) Validate 

func (t *SSHTemplates) Validate() (err error)

Validate returns an error if a template is not valid.

type Step 

type Step struct {
	SSH StepSSH
}

Step represents the default variables available in the CA.

type StepSSH 

type StepSSH struct {
	HostKey           ssh.PublicKey
	UserKey           ssh.PublicKey
	HostFederatedKeys []ssh.PublicKey
	UserFederatedKeys []ssh.PublicKey
}

StepSSH holds SSH-related values for the CA.

type Template 

type Template struct {
	*template.Template
	Name         string       `json:"name"`

func (t *Template) ValidateRequiredData(data map[string]string) error

ValidateRequiredData checks that the given data contains all the keys required.

type TemplateType 

type TemplateType string

TemplateType defines how a template will be written in disk. 

const (
	// Snippet will mark a template as a part of a file.
	Snippet TemplateType = "snippet"
	// File will mark a templates as a full file.
	File TemplateType = "file"
	// Directory will mark a template as a directory.
	Directory TemplateType = "directory"
)

type Templates 

type Templates struct {
	SSH  *SSHTemplates          `json:"ssh,omitempty"`
	Data map[string]interface{} `json:"data,omitempty"`
}
