Golang Admin Client API Reference

The MinIO Admin Golang Client SDK provides APIs to manage MinIO services.

This quickstart guide will show you how to install the MinIO Admin client SDK, connect to MinIO admin service, and provide a walkthrough of a simple file uploader.

This document assumes that you have a working Golang setup.

Initialize MinIO Admin Client object.

MinIO

package main

import (
    "fmt"

    "github.com/minio/minio/pkg/madmin"
)

func main() {
    // Use a secure connection.
    ssl := true

    // Initialize minio client object.
    mdmClnt, err := madmin.New("your-minio.example.com:9000", "YOUR-ACCESSKEYID", "YOUR-SECRETKEY", ssl)
    if err != nil {
        fmt.Println(err)
        return
    }

    // Fetch service status.
    st, err := mdmClnt.ServerInfo()
    if err != nil {
        fmt.Println(err)
        return
    }
	for _, peerInfo := range serversInfo {
		log.Printf("Node: %s, Info: %v\n", peerInfo.Addr, peerInfo.Data)
	}
}

5. Heal operations

Heal(ctx context.Context, bucket, prefix string, healOpts HealOpts, clientToken string, forceStart bool, forceStop bool) (start HealStartSuccess, status HealTaskStatus, err error)

Start a heal sequence that scans data under given (possible empty) bucket and prefix. The recursive bool turns on recursive traversal under the given path. dryRun does not mutate on-disk data, but performs data validation.

Two heal sequences on overlapping paths may not be initiated.

The progress of a heal should be followed using the same API Heal by providing the clientToken previously obtained from a Heal API. The server accumulates results of the heal traversal and waits for the client to receive and acknowledge them using the status request by providing clientToken.

Example

    opts := madmin.HealOpts{
            Recursive: true,
            DryRun:    false,
    }
    forceStart := false

s.ClientAddress	string	Address of the client which initiated the heal operation, the client address has the form "host:port".
s.StartTime	time.Time	Time when heal was initially started.

HealTaskStatus structure

Param	Type	Description

Type	HealItemType	Represents kind of heal operation in the heal record
Bucket	string	Bucket name

    }

    out, err := json.Marshal(locks)
    if err != nil {
        log.Fatalf("Marshal failed due to: %v", err)

    }

9. Misc operations
