Create a crawler schedule

You can create a schedule for the crawler using the AWS Glue console or AWS CLI.

AWS Management Console

  1. Sign in to the AWS Management Console, and open the AWS Glue console at https://eusc-de-east-1.console.amazonaws-eusc.eu/glue/.

  2. Choose Crawlers in the navigation pane.

  3. Follow steps 1-3 in the Configuring a crawler section.

  4. In Step 4: Set output and scheduling, choose a Crawler schedule to set the frequency of the run. You can choose the crawler to run hourly, daily, weekly, monthly or define custom schedule using cron expressions.

    A cron expression is a string representing a schedule pattern, consisting of 6 fields separated by spaces: * * * * * <minute> <hour> <day of month> <month> <day of week> <year>

    For example, to run a task every day at midnight, the cron expression is: 0 0 * * ? *

    For more information, see Cron expressions.

  5. Review the crawler settings you configured, and create the crawler to run on a schedule.

AWS CLI
aws glue create-crawler 
 --name myCrawler \
 --role AWSGlueServiceRole-myCrawler  \
 --targets '{"S3Targets":[{Path="s3://amzn-s3-demo-bucket/"}]}' \
 --schedule cron(15 12 * * ? *)
