Setting up authentication for cataloging Amazon DMS

This section walks you through the process of setting up authentication for cataloging Amazon DMS.

STEP 1: Creating a user

For detailed instructions, refer to the AWS documentation.

To create a user for running the collector:

  1. Login to the AWS portal and navigate to IAM service.

  2. Under Users, click Create user or select an existing user.

  3. On the next screen, on the Set permissions page set the following:

    1. Add the user to a new or existing group with the following permissions: dms:DescribeReplicationTasks, dms:DescribeReplicationInstances, dms:DescribeEndpoints, dms:DescribeConnections.

    2. Attach policies directly by selecting or creating a new policy with the necessary permissions. Click Next.

  4. On the next screen, review the details and click Create user.

STEP 2: Obtaining access key for the user

Skip this step if you already have the access key for the user that you plan to use for running the collector. For detailed instructions, refer to the AWS documentation.

To obtain an access key for the user:

  1. Login to the AWS portal and navigate to IAM service.

  2. Under Users, select the user that plan to use for the collector.

  3. On the Security credentials tab, click Create access key.

  4. Select Application running outside AWS. Click Next.

  5. Add the optional Description tag. Click Create Access key.

  6. Note down the Access key ID and Secret access key. You will need this information for setting up the credentials file.

STEP 3: Setting up credentials file

If you are authenticating to Amazon DMS using the AWS credentials file, make sure you have the credentials file located at ~/.aws/credentials. For more details, refer to the AWS documentation.

To set up credentials file:

  1. Install the AWS CLI.

  2. From the command line, run aws configure. This stores the credentials to ~/.aws/credentials.
