4. If it's a new route, it connects by building either a direct socket connection, a TLS tunnel (for HTTPS over an HTTP proxy), or a direct TLS connection. It does TLS handshakes as necessary. This step may be retried for tunnel challenges and TLS handshake failures.
 5. It sends the HTTP request and reads the response.

### 1. Fetch the root identity

As the initial step, fetch the private key and certificate of the root identity:

```sh
curl -sSL --tlsv1.2 \
     -O 'https://raw.githubusercontent.com/minio/kes/master/root.key' \

We’ve included deprecated APIs in OkHttp 4.0 because they make migration easy. We will remove them
in a future release! If you’re skipping releases, it’ll be much easier if you upgrade to OkHttp 4.0
as an intermediate step.

#### Vars and Vals

Java doesn’t have language support for properties so developers make do with getters and setters.
Kotlin does have properties and we take advantage of them in OkHttp.

     * #COMPLETED}, {@link #CANCELLED}, or {@link #INTERRUPTED}
     *
     * <p>To avoid races between threads doing release and acquire, we transition to the final state
     * in two steps. One thread will successfully CAS from RUNNING to COMPLETING, that thread will
     * then set the result of the computation, and only then transition to COMPLETED, CANCELLED, or
     * INTERRUPTED.
     *

因此，以下皆是不同的來源：

* `http://localhost`
* `https://localhost`
* `http://localhost:8080`

即使它們都在 `localhost`，但使用了不同的通訊協定或連接埠，所以它們是不同的「來源」。

## 步驟 { #steps }

假設你的前端在瀏覽器中執行於 `http://localhost:8080`，其 JavaScript 嘗試與執行在 `http://localhost` 的後端通訊（因為未指定連接埠，瀏覽器會假設預設連接埠為 `80`）。

## Prerequisites

To get started with MinIO, refer [MinIO QuickStart Document](https://docs.min.io/community/minio-object-store/operations/deployments/baremetal-deploy-minio-on-redhat-linux.html).
Follow below steps to get started with MinIO monitoring using Prometheus.

### 1. Download Prometheus

[Download the latest release](https://prometheus.io/download) of Prometheus for your platform, then extract it

```sh

  workflow_dispatch:

permissions:
  contents: read

jobs:
  rbe:
    name: Update RBE Configs
    runs-on: ubuntu-latest
    if: github.repository == 'tensorflow/tensorflow' # Don't do this in forks
    steps:
    - name: Checkout code
      uses: actions/checkout@8e8c483db84b4bee98b60c0593521ed34d9990e8 # v6.0.1
    - name: Update the RBE Configs
      run: |
        function map() {

* Разделять соединения с базой данных.
* Обеспечить безопасность, аутентификацию, требования к ролям и т.п.
* И многое другое...

Всё это при минимизации повторения кода.

## Первые шаги { #first-steps }

Давайте рассмотрим очень простой пример. Он настолько простой, что пока не очень полезен.

Но так мы сможем сосредоточиться на том, как работает система **Dependency Injection**.

Ich werde Ihnen in einem zukünftigen Kapitel mehr über Container-Images, Docker, Kubernetes, usw. erzählen: [FastAPI in Containern – Docker](docker.md).

## Schritte vor dem Start { #previous-steps-before-starting }

Es gibt viele Fälle, in denen Sie, **bevor Sie Ihre Anwendung starten**, einige Schritte ausführen möchten.

Beispielsweise möchten Sie möglicherweise **Datenbankmigrationen** ausführen.

### Using WebIdentiy API

Client ID can be found by clicking any of the clients listed [here](http://localhost:8080/auth/admin/master/console/#/realms/minio/clients). If you have followed the above steps docs, the default Client ID will be `account`.
