Using the MinIO API via curl

Using the MinIO API via curl is straightforward, as MinIO is compatible with Amazon S3 API, so most commands follow a similar syntax. Here’s a guide on how to use curl with the MinIO API for some common operations like uploading, downloading, and managing objects.

Prerequisites

  1. Access Key and Secret Key: Obtain your MinIO Access Key and Secret Key.
  2. MinIO Endpoint: Know your MinIO server endpoint, e.g., http://localhost:9000.
  3. Bucket: You may need an existing bucket name, or create a new one using the commands below.

Authentication Header

For requests to work with MinIO, you need to include authentication in the headers. MinIO uses AWS Signature Version 4 for signing requests.

Common Examples

1. List Buckets

To list all buckets in your MinIO account, use:

curl -X GET \
  --url "http://localhost:9000/" \
  -H "Authorization: AWS <AccessKey>:<Signature>"

2. Create a Bucket

To create a new bucket, use:

curl -X PUT \
  --url "http://localhost:9000/<bucket-name>" \
  -H "Authorization: AWS <AccessKey>:<Signature>"

Replace <bucket-name> with your desired bucket name.

3. Upload an Object

To upload a file to a bucket, you can use the PUT method.

curl -X PUT \
  --url "http://localhost:9000/<bucket-name>/<object-name>" \
  -H "Authorization: AWS <AccessKey>:<Signature>" \
  --upload-file "<file-path>"

Replace <bucket-name> with the name of your bucket, <object-name> with the name you want for the uploaded object, and <file-path> with the path to the file on your system.

4. Download an Object

To download an object, use the GET method.

curl -X GET \
  --url "http://localhost:9000/<bucket-name>/<object-name>" \
  -H "Authorization: AWS <AccessKey>:<Signature>" \
  -o "<local-file-path>"

Replace <bucket-name>, <object-name>, and <local-file-path> accordingly.

5. List Objects in a Bucket

To list all objects in a bucket, use:

curl -X GET \
  --url "http://localhost:9000/<bucket-name>" \
  -H "Authorization: AWS <AccessKey>:<Signature>"

Generating the Signature

The Authorization header should contain a signature created using AWS Signature Version 4, which can be complex to generate manually. It may be easier to use tools, libraries, or pre-built clients like the MinIO Client (mc) or AWS SDKs to handle this signature.

Automating the Signing Process

Alternatively, tools like AWS CLI, MinIO Client (mc), or libraries for Python, Java, etc., can make requests easier and handle the signing process internally.

Let me know if you need additional examples or help with signing.

How to checkout branch of remote git, 깃 리모트 브랜치 체크아웃

To check out a branch from a remote Git repository, you can follow these steps: 1. Fetch the remote branches First, ensure that your local repository is aware of the remote branches by using git fetch . This updates your local references to the remote branches. git fetch origin 2. Check out the remote branch Once the remote branches are fetched, you can check out the desired branch using git checkout -b and specifying the remote branch. Command: git checkout -b < local -branch- name > origin/<remote-branch- name > Explanation: <local-branch-name> : The name you want to give to your local branch. origin/<remote-branch-name> : Refers to the branch on the remote called origin (which is the default name for the main remote repository) and the branch you want to check out. Example: If the remote branch is called feature-branch and you want to create a local branch with the same name, you would run: git checkout -b feature -branch origin / feature -...

To download a file from MinIO using Spring Boot, 스프링부트 Minio 사용하기

To download a file from MinIO using Spring Boot, you can utilize the MinIO Java SDK. Here's an example of how you can achieve this: Add the MinIO dependency to your pom.xml file: < dependency > < groupId > io.minio </ groupId > < artifactId > minio </ artifactId > < version > 7.1.0 </ version > </ dependency > Create a configuration file (e.g., MinioConfig.java ) to establish a connection with your MinIO server: ```java import io.minio.MinioClient; import org.springframework.beans.factory.annotation.Value; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; @Configuration public class MinioConfig { @Value( " ${minio.endpoint} " ) private String endpoint; @Value( " ${minio.accessKey} " ) private String accessKey; @Value( " ${minio.secretKey} " ) private String secretKey; @Bean public MinioClient minioClient() { re...

Declaration of custom object or type in Node.js

In Node.js, when you want to assign one object to another that is declared by a custom type or class, you typically need to ensure compatibility between the source object's structure and the target class's expectations. Here's a breakdown: Scenario 1: Assigning Plain Objects to Class Instances If you have a custom class and want to assign properties from a plain object to an instance of that class, you can use one of the following methods: Example: class CustomType { constructor (name, age) { this .name = name; this .age = age; } } // Plain object const plainObject = { name : "John" , age : 30 }; // Assign using Object.assign() const customInstance = new CustomType(); Object .assign(customInstance, plainObject); console .log(customInstance instanceof CustomType); // true console .log(customInstance); // CustomType { name: 'John', age: 30 } Scenario 2: Using a Constructor You can modify your class to accept an object in the c...

2025 대학수학능력시험 9월 모의평가 듣기 16-17

Good morning, students. Today, we’re going to learn about the key characteristics that enable some animals to reach high speeds. First, there’s no animal faster on land than the cheetah. Its flexible backbone and joints allow for extreme extension, enabling it to stretch its legs very far and push off its back legs with great force like a spring. Second, the falcon is one of the fastest birds. Its large breastbone allows more muscle to be attached to it, so it can beat its wings with greater power. Third, the swordfish is among the fastest fish in the sea. It releases a special, slippery oil from its head that coats the front of its body, enabling it to swim with less resistance. Lastly, the dragonfly is considered the world’s fastest flying insect. It has the unique ability to slightly twist its wings as they swing down, causing a small tornado-like wind that gives it a boost of speed. Now, let’s watch a video of nature’s speedsters. *breastbone: 흉골, 가슴뼈  *coat: ~에 칠하다, 웃옷을 입히다

리눅스의 부팅과정

1. 컴퓨터에 전원이 들어오면 POST 과정에 의한 시스템 초기화 2. Boot Record나 하드인 경우 MBR(Master Boot Record)를 읽어들인다. 3. LILO(Linux Loader)가 실행된다. 만일, 디폴트인 리눅스가 로딩되기 전에 Ctrl,Shift,Alt 중 하나를 누르고 있으면, LILO는 부팅할 운영체제를 물어 본다. 4. Kernel이 메모리로 로딩되며, 만일 커널이 압축되었다면 압축을 해제한다. 5. 커널은 하드, 플로피, 네트웍 어댑터 등을 검사하며, 디바이스 드라이버를 설정한다. 6. 리눅스는 프로세서를 보호모드로 전환시키다. 화면상의 변화는 나타나지 않는다. 7. root 파일 시스템을 마운트 시킨다. root 파일 시스템은 'rdev' 나 LILO 에 의해 설정되어 있으며, 파일 시스템의 형태는 자동적으로 검출된다. 8. 커널은 /etc/init 을 백그라운드로 실행한다. 'init' 는 'inittab' 파일의 내용에 따라 실행된다. 9. init 는 /etc/rc 를 실행한다. 10. 'rc' 는 /etc/rc.local 이나 /etc/rc[0-9] 등을 실행시킨다. 11. 'init' 프로그램은 가상 콘솔을 위해 /etc/gettytabs 에 의해 설정된 직렬 라인으로 getty 를 실행한다. 12. ID 와 패스워드를 입력한다. 13. shell 이 작동하고 bash shell 이면 .bashrc 를, tcsh shell 이면 .profile 을 불러들인다. 14. 프롬프트가 표시된다. 위 부팅과정의 8번에서 있는 것처럼 리눅스는 처음 부팅을 하면서 init 프로세스가 /etc/inittab 이라는 파일을 불러들이게 되는데, 이 파일에는 부팅시 불러올 런레벨을 결정하는 부분이 있는데, 이 파일의 내용은 아래와 같다. [root@hostname /etc]# vi /etc/inittab # # inittab ...

The logs of the kubelet service

The logs of the kubelet service can be found depending on how the system is set up. Here are the most common locations: 1. Systemd Logs If your system uses systemd to manage services (most modern Linux distributions do), you can view the kubelet logs using journalctl : View Real-time Logs: sudo journalctl -u kubelet -f View Historical Logs: sudo journalctl -u kubelet 2. Log File on Disk On some systems, kubelet writes its logs to a file in /var/log . The exact location depends on the configuration: Common Locations : /var/log/kubelet.log /var/lib/kubelet/logs If the log file is not there, check the kubelet service configuration for custom log paths. 3. Kubernetes Configuration Flags The kubelet log location can be customized using the --log-dir or --log-file flags in the kubelet service configuration. To verify: Check the kubelet service file: cat /etc/systemd/system/kubelet .service .d / 10 -kubeadm.conf Look for logging-related flags, such as: Exec...
