Installation

Etcd is tested on the 2 last Go versions with support for modules. So make sure to initialize one first if you didn't do that yet:

go mod init github.com/<user>/<repo>

And then install the etcd implementation:

go get github.com/gofiber/storage/etcd/v2

Examples

Import the storage package.

import "github.com/gofiber/storage/etcd/v2"

You can use the following possibilities to create a storage:

// Initialize default config
store := etcd.New()

// Initialize custom config
store := etcd.New(Config{
    Endpoints: []string{"localhost:2379"},
})

Config

type Config struct {
    // Endpoints is a list of URLs.
    Endpoints   []string
    // DialTimeout is the timeout for failing to establish a connection.
    DialTimeout time.Duration
    // Username is a username for authentication.
    Username    string
    // Password is a password for authentication.
    Password    string
	// TLS holds the client secure credentials, if any.
	TLS *tls.Config
}

Default Config

var ConfigDefault = Config{
    Endpoints:   []string{"localhost:2379"},
    DialTimeout: 2 * time.Second,
    Username:    "",
    Password:    "",
    TLS:         nil,
}
