QLDB examples using Amazon CLI - Amazon Command Line Interface
Actions
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

This documentation is for Version 1 of the Amazon CLI only. For documentation related to Version 2 of the Amazon CLI, see the Version 2 User Guide.

QLDB examples using Amazon CLI

The following code examples show you how to perform actions and implement common scenarios by using the Amazon Command Line Interface with QLDB.

Actions are code excerpts from larger programs and must be run in context. While actions show you how to call individual service functions, you can see actions in context in their related scenarios.

Each example includes a link to the complete source code, where you can find instructions on how to set up and run the code in context.

The following code example shows how to use cancel-journal-kinesis-stream.

Amazon CLI

To cancel a journal stream

The following cancel-journal-kinesis-stream example cancels the specified journal stream from a ledger.

aws qldb cancel-journal-kinesis-stream \
    --ledger-name myExampleLedger \
    --stream-id 7ISCkqwe4y25YyHLzYUFAf

Output:

{
    "StreamId": "7ISCkqwe4y25YyHLzYUFAf"
}

The following code example shows how to use create-ledger.

Amazon CLI

Example 1: To create a ledger with default properties

The following create-ledger example creates a ledger with the name myExampleLedger and the permissions mode STANDARD. The optional parameters for deletion protection and Amazon KMS key are not specified, so they default to true and an Amazon owned KMS key respectively.

aws qldb create-ledger \
    --name myExampleLedger \
    --permissions-mode STANDARD

Output:

{
    "State": "CREATING",
    "Arn": "arn:aws:qldb:us-west-2:123456789012:ledger/myExampleLedger",
    "DeletionProtection": true,
    "CreationDateTime": 1568839243.951,
    "Name": "myExampleLedger",
    "PermissionsMode": "STANDARD"
}

Example 2: To create a ledger with deletion protection disabled, a customer managed KMS key, and specified tags

The following create-ledger example creates a ledger with the name myExampleLedger2 and the permissions mode STANDARD. The deletion protection feature is disabled, the specified customer managed KMS key is used for encryption at rest, and the specified tags are attached to the resource.

aws qldb create-ledger \
    --name myExampleLedger2 \
    --permissions-mode STANDARD \
    --no-deletion-protection \
    --kms-key arn:aws:kms:us-west-2:123456789012:key/a1b2c3d4-5678-90ab-cdef-EXAMPLE11111 \
    --tags IsTest=true,Domain=Test

Output:

{
    "Arn": "arn:aws:qldb:us-west-2:123456789012:ledger/myExampleLedger2",
    "DeletionProtection": false,
    "CreationDateTime": 1568839543.557,
