Machine.json File Creation

This wiki describes how to create machine.json file automatically when you build K8s-Mizar-Mp set up with Alcor Controller and Agents. Section 1 and 2 are from the following web page:
https://docs.aws.amazon.com/sdk-for-java/v2/developer-guide/setup-credentials.html

Before starting, you need to prepare the following information:

• AWS_ACCESS_KEY_ID &  AWS_SECRET_ACCESS_KEY
• AWS EC2 instances and their region information
• Java 1.8 or above

1.Setting AWS Credentials

You can set your credentials for use by the AWS SDK for Java in several ways. However, these are the recommended approaches:

Set credentials in the AWS credentials profile file on your local system, located at:

  ~/.aws/credentials on Linux, macOS, or Unix 
  C:\Users\USERNAME\.aws\credentials on Windows 

This file should contain lines in the following format:

  [default]
  aws_access_key_id = your_access_key_id
  aws_secret_access_key = your_secret_access_key

Substitute your own AWS credentials values for the values your_access_key_id and your_secret_access_key.

Set the AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY environment variables. To set these variables on Linux, macOS, or Unix, use export :

  export AWS_ACCESS_KEY_ID=your_access_key_id
  export AWS_SECRET_ACCESS_KEY=your_secret_access_key

To set these variables on Windows, use set :

  set AWS_ACCESS_KEY_ID=your_access_key_id
  set AWS_SECRET_ACCESS_KEY=your_secret_access_key

2. Setting the AWS Region

You should set a default AWS Region to use for accessing AWS services with the AWS SDK for Java. For the best network performance, choose a region that’s geographically close to you (or to your customers). Note) If you don’t select a region, service calls that require a region will fail. You can use techniques similar to those for setting credentials to set your default AWS Region:

Set the AWS Region in the AWS config file on your local system, located at: ~/.aws/config on Linux, macOS, or Unix C:\Users\USERNAME.aws\config on Windows

This file should contain lines in the following format:

    [default]
    region = your_aws_region

Substitute your desired AWS Region (for example, “us-west-2”) for your_aws_region.

Set the AWS_REGION environment variable.

On Linux, macOS, or Unix, use export:

  export AWS_REGION=your_aws_region

On Windows, use set :

  set AWS_REGION=your_aws_region,       Where your_aws_region is the desired AWS Region name. 

3. Setting the AWS Region

Move to AwsClient directory and Build a tool.

• cd ~/mizar-mp/tools/AwsClient
• chmod +x ./scripts/*.sh
• ./scripts/build_tool.sh

Run a tool.

$>./scriot/run_tool.sh
$>cat machine.json
