Create a Data Source: immuta datasource save

1. Add your remote database's connection information in a valid YAML file for the V2 API. Additional payload examples for creating data sources can be found here:

   connectionKey: 'a connection key'
   connection:
     ssl: true
     port: 5432
     hostname: immuta.db.com
     database: public
     schema: public
     username: user
     password: '{{EnvVar "myPassword"}}'
     handler: Snowflake

2. Run immuta datasource save <filepath> [--wait int] [--dryRun], referencing the file you just created. The options you can specify include

   • -d or --dryRun: No updates will actually be made to the data source(s).

   • -h or --help: Get more information about the command.

   • -w or --wait int: Specify how long to wait for data source creation.

Example

The following example illustrates a user saving an updated datasourceInfo.yaml file, first as a dry run and then by specifying that the data sources wait 5 seconds to be created.

$ immuta datasource save test.yml --dryRun
{"dryRun":true,"creating":["Public Credit Accounts","Public Credit Transactions","Public Fake Medical Claims 2017","Public Uciml Census Income Enriched"],"updating":[],"deleting":[],"noChange":[],"detectionRunning":false,"tagsUpdated":false,"connectionString":null}

$ immuta datasource save test.yml --wait 5
{"dryRun":false,"creating":["Public Credit Accounts","Public Credit Transactions","Public Fake Medical Claims 2017","Public Uciml Census Income Enriched"],"updating":[],"deleting":[],"noChange":[],"detectionRunning":false,"tagsUpdated":false,"connectionString":"[e-mail]:3306/public"}
