Customize SDK client

Last update: November 21 2025

You can set up your own SDK client in Python or Go to work with logs.

For the SDK client, you can:

• Set the configurations of the customized AWS CLI;
• Override AWS CLI configurations;
• set custom configurations.

Python

AWS CLI Configuration

1. Open the CLI.

2. Install boto3 to customize dependencies:

   pip install boto3

3. Configure the AWS CLI.

4. Configure the client with the configurations you set for the AWS CLI:

   import boto3
   
   client = boto3.client('logs')

Overridden AWS CLI configurations

1. Open the CLI.

2. Install boto3 to customize dependencies:

   pip install boto3

3. Configure the AWS CLI.

4. Open an existing script file or create a new one.

5. Copy the script to a file. You can override AWS CLI configurations in the script:

   import boto3
   
   access_key = '<access_key>'
   secret_key = '<secret_key>'
   region = '<pool>'
   
   client = boto3.client(
       'logs', 
       aws_access_key_id=access_key,
       aws_secret_access_key=secret_key,
       region_name=region,
       endpoint_url=f'https://{region}.logs.selcloud.ru'
   )

   Specify:

   • optional: <access_key> — the value of the Access key field from the S3 key you issued to the user;
   • optional: <secret_key> — the value of  the Secret key field from the S3 key you issued to the user;
   • optional: < pool > — a pool for generating URLs for accessing the Logi service (e.g., ru-8).

Custom configurations

1. Open the CLI.

2. Install boto3 to customize dependencies:

   pip install boto3

3. Open an existing script file or create a new one.

4. Copy the script into a file:

   import boto3
   
   access_key = '<access_key>'
   secret_key = '<secret_key>'
   region = '<pool>'
   
   client = boto3.client(
       'logs', 
       aws_access_key_id=access_key,
       aws_secret_access_key=secret_key,
       region_name=region,
       endpoint_url=f'https://{region}.logs.selcloud.ru'
   )

   Specify:

   • <access_key> — field value Access key from the S3 key you issued to the user;
   • <secret_key> — field value Secret key from the S3 key you issued to the user;
   • <pool> — pool for generating URL address to the Logi service (e.g, ru-8).

Go

AWS CLI configurations

1. Open the CLI.

2. Download the packages to create the client:

   go get github.com/aws/aws-sdk-go-v2
   go get github.com/aws/aws-sdk-go-v2/config
   go get github.com/aws/aws-sdk-go-v2/service/cloudwatchlogs
   go get github.com/aws/aws-sdk-go-v2/credentials

3. Configure the AWS CLI.

4. Open an existing script file or create a new one.

5. Copy the script to a file.The script will configure the client with the configurations you set for the AWS CLI:

package main

import (
  "context"
  "fmt"
  "log"

  "github.com/aws/aws-sdk-go-v2/config"
  "github.com/aws/aws-sdk-go-v2/service/cloudwatchlogs"
)

func main() {
  cfg, err := config.LoadDefaultConfig(context.TODO())
  if err != nil {
    log.Fatalf("Ошибка загрузки конфигурации: %v", err)
  }

  client := cloudwatchlogs.NewFromConfig(cfg)

  fmt.Println("CloudWatch Logs Сlient создан:", client)
}

Overridden AWS CLI configurations

1. Open the CLI.

2. Download the packages to create the client:

   go get github.com/aws/aws-sdk-go-v2
   go get github.com/aws/aws-sdk-go-v2/config
   go get github.com/aws/aws-sdk-go-v2/service/cloudwatchlogs
   go get github.com/aws/aws-sdk-go-v2/credentials

3. Configure the AWS CLI.

4. Open an existing script file or create a new one.

5. Copy the script to a file. You can override AWS CLI configurations in the script:

package main

import (
  "context"
  "fmt"
  "log"

  "github.com/aws/aws-sdk-go-v2/aws"
  "github.com/aws/aws-sdk-go-v2/config"

)

func main() {
  accessKey := "<access_key>"
  secretKey := "<secret_key>"
  region := "<pool>"

  endpoint := fmt.Sprintf("https://%s.logs.selcloud.ru", region)

  customResolver := aws.EndpointResolverFunc(func(service, region string) (aws.Endpoint, error) {
    if service == cloudwatchlogs.ServiceID {
      return aws.Endpoint{
        URL:           endpoint,
        SigningRegion: region,
      }, nil
    }
    return aws.Endpoint{}, fmt.Errorf("Неизвестный сервис: %s", service)
  })

  cfg, err := config.LoadDefaultConfig(context.TODO(),
    config.WithRegion(region),
    config.WithCredentialsProvider(credentials.NewStaticCredentialsProvider(accessKey, secretKey, "")),
    config.WithEndpointResolver(customResolver),
  )
  if err != nil {
    log.Fatalf("Ошибка загрузки конфигурации: %v", err)
  }

  client := cloudwatchlogs.NewFromConfig(cfg)

  fmt.Println("CloudWatch Logs Client создан:", client)
}
