Functions

func ConfigMapAsString

func ConfigMapAsString() string

ConfigMapAsString returns a ConfigMap with the default NGINX configuration to be used a guide to provide a custom configuration

Types

type IngressConfig

type IngressConfig struct {
	Upstreams    []*Upstream
	Servers      []*Server
	TCPUpstreams []*Location
}

IngressConfig describes an NGINX configuration

type Location

type Location struct {
	Path     string
	Upstream Upstream
}

Location describes an NGINX location

type LocationByPath

type LocationByPath []*Location

LocationByPath sorts location by path

func (LocationByPath) Len

func (c LocationByPath) Len() int

func (LocationByPath) Less

func (c LocationByPath) Less(i, j int) bool

func (LocationByPath) Swap

func (c LocationByPath) Swap(i, j int)

type Manager

type Manager struct {
	ConfigFile string
	// contains filtered or unexported fields
}

Manager ...

func NewManager

func NewManager(kubeClient *client.Client) *Manager

NewManager ...

func (*Manager) AddOrUpdateCertAndKey

func (nginx *Manager) AddOrUpdateCertAndKey(name string, cert string, key string) string

AddOrUpdateCertAndKey creates a .pem file wth the cert and the key with the specified name

func (Manager) Check

func (ngx Manager) Check(_ *http.Request) error

Check returns if the nginx healthz endpoint is returning ok (status code 200)

func (*Manager) CheckAndReload

func (ngx *Manager) CheckAndReload(cfg nginxConfiguration, ingressCfg IngressConfig)

CheckAndReload verify if the nginx configuration changed and sends a reload

the master process receives the signal to reload configuration, it checks the syntax validity of the new configuration file and tries to apply the configuration provided in it. If this is a success, the master process starts new worker processes and sends messages to old worker processes, requesting them to shut down. Otherwise, the master process rolls back the changes and continues to work with the old configuration. Old worker processes, receiving a command to shut down, stop accepting new connections and continue to service current requests until all such requests are serviced. After that, the old worker processes exit. http://nginx.org/en/docs/beginners_guide.html#control

func (*Manager) CheckSSLCertificate

func (nginx *Manager) CheckSSLCertificate(pemFileName string) ([]string, error)

CheckSSLCertificate checks if the certificate and key file are valid returning the result of the validation and the list of hostnames contained in the common name/s

func (Manager) Name

func (ngx Manager) Name() string

Name returns the healthcheck name

func (*Manager) ReadConfig

func (ngx *Manager) ReadConfig(config *api.ConfigMap) nginxConfiguration

ReadConfig obtains the configuration defined by the user merged with the defaults.

func (*Manager) SearchDHParamFile

func (nginx *Manager) SearchDHParamFile(baseDir string) string

SearchDHParamFile iterates all the secrets mounted inside the /etc/nginx-ssl directory in order to find a file with the name dhparam.pem. If such file exists it will returns the path. If not it just returns an empty string

func (*Manager) Start

func (ngx *Manager) Start()

Start starts a nginx (master process) and waits. If the process ends we need to kill the controller process and return the reason.

type Server

type Server struct {
	Name              string
