On a Linux Jenkins server, you can install AWS CLI using the package manager. For example, on Ubuntu, you can use:

     ```

     sudo apt-get update

     sudo apt-get install awscli

     ```

On Windows, you can download and run the AWS CLI MSI installer from the AWS website.

Run `aws configure` to set up your AWS credentials (Access Key ID and Secret Access Key), default region, and output format.

Enter the required information when prompted. You can get these credentials from your AWS IAM (Identity and Access Management) user.

Make sure the IAM user has the necessary permissions to access the S3 bucket.

You can create a bucket using the AWS Management Console or CLI:

     ```

     aws s3 mb s3://your-bucket-name

     ```

Attach an IAM policy to the Jenkins server's IAM role or user that allows it to put objects in the S3 bucket. The policy should look something like this:

     ```json

     {

       "Version": "2012-10-17",

       "Statement": [

         {

           "Effect": "Allow",

           "Action": [

             "s3:PutObject",

             "s3:PutObjectAcl"

           ],

           "Resource": "arn:aws:s3:::your-bucket-name/*"

         }

       ]

     }

     ```

Ensure that the data you want to move to S3 is available on the Jenkins server and is in a directory or file format that can be easily transferred.

Use the `aws s3 cp` command to copy data from the Jenkins server to the S3 bucket.

For a single file, the command is:

     ```

     aws s3 cp /path/to/your/file s3://your-bucket-name/path/in/bucket/

     ```

   - For an entire directory, use the `--recursive` option:

     ```

     aws s3 cp /path/to/your/directory s3://your-bucket-name/path/in/bucket/ --recursive

     ```

You can add a build step or a post-build step in your Jenkins job to execute the AWS CLI command.

Use the "Execute shell" or "Execute Windows batch command" step, depending on your Jenkins server OS, and paste the AWS CLI command you used earlier.

After the Jenkins job runs, verify that the files have been successfully transferred to the S3 bucket.

You can check the S3 bucket using the AWS Management Console or by running:

     ```

     aws s3 ls s3://your-bucket-name/path/in/bucket/

     ```

• If the transfer fails, check the Jenkins console output for errors.
• Verify that the AWS CLI is correctly installed and configured.
• Ensure that the IAM user or role has the necessary permissions to access the S3 bucket.
• Check for typos in the bucket name or file paths.
