In the first stage ‘S3 Path Validation‘ I check that S3_PATH is not empty and then determine that provided path is an object or a folder.
In the second stage I’m creating a new directory and then running mounting command for EFS. Right after that I changing ownership to the Jenkins user. It’s important step, otherwise the copy command might fail due to lack of permissions.
In the next stage I just printing content of the directory where I mounted EFS and then Im validating that provided path on EFS exists.
‘Copy From S3 to EFS’ stage – here I construct the final path and depends on what was provided on S3_PATH I finally running aws s3 cp command which copies S3 objects to the mounted EFS.
In the post stage I removing the workspace by deleteDir() command and un-mounting the EFS.
