How to Sync to Manually
Step 1: Set Up AWS CloudTrail Logging
Begin by ensuring that AWS CloudTrail is properly configured to log events. Navigate to the AWS CloudTrail console, and create or verify an existing trail that logs management and data events. Ensure that the trail is set to deliver logs to an S3 bucket. This S3 bucket will serve as the source of the CloudTrail logs.
Step 2: Configure S3 Bucket for Log Storage
Set up an S3 bucket to store CloudTrail logs. Ensure correct permissions are in place so that CloudTrail can write logs to this bucket. You may need to set up an S3 bucket policy that allows CloudTrail to perform necessary actions like `s3:PutObject`.
Step 3: Set Up AWS Identity and Access Management (IAM) Roles
Create an IAM role with permissions to read from your S3 bucket. This role will be used later to access the logs when transferring data to ClickHouse. Make sure the role has the `s3:GetObject` permission for the S3 bucket containing the CloudTrail logs.
Step 4: Install and Configure AWS CLI
Install the AWS Command Line Interface (CLI) on your local machine or a server that will orchestrate the data transfer. Configure the CLI with the necessary credentials and region settings. Use the `aws configure` command to enter your AWS Access Key, Secret Key, and preferred region.
Step 5: Download CloudTrail Logs
Use the AWS CLI to download the CloudTrail logs from the S3 bucket to a local or intermediate storage. Execute a command like `aws s3 cp s3://your-cloudtrail-bucket/path/to/logs/ /local/path/ --recursive` to download logs recursively. This step ensures you have access to the raw log data for processing.
Step 6: Parse and Transform CloudTrail Logs
Develop a script or use a tool (like a Python script with the `json` module) to parse the JSON-formatted CloudTrail logs. Transform the data into a CSV format or another structured format that ClickHouse can ingest. Ensure the script extracts relevant fields and formats them correctly.
Step 7: Load Data into ClickHouse
Use ClickHouse's native tools to load the transformed data. You can use the `clickhouse-client` command-line tool to execute SQL queries that insert the data into your ClickHouse tables. For example, use `clickhouse-client --query="INSERT INTO your_table FORMAT CSV" < /path/to/transformed_data.csv` to load the data. Ensure that the ClickHouse table schema matches the structure of your transformed data.
By following these steps, you can successfully move data from AWS CloudTrail to a ClickHouse warehouse without relying on third-party connectors or integrations.
