gcloud alpha composer environments storage data export - export data from an environment into local storage or Cloud Storage

gcloud alpha composer environments storage data export--destination=DESTINATION(--environment=ENVIRONMENT :--location=LOCATION)[--source=SOURCE][GCLOUD_WIDE_FLAG …]

gs://the-bucket|+--data|||+--file1.txt|+--file2.txt|||+--subdir1|||||+--file3.txt||+--file4.txt

And the local directory '/foo' has the following structure:

/foo|+--file1.txt+--fileX.txt|||+--subdir1|||||+--file3.txt||+--fileY.txt

The following command:

gcloudalphacomposerenvironmentsstoragedataexportmyenv--destination=/foo

would result in the following structure in the local '/foo' directory:

/foo|+--file1.txt+--file2.txt+--fileX.txt|||+--subdir1|||||+--file3.txt||+--file4.txt||+--fileY.txt

The local files '/foo/file1.txt' and '/foo/subdir1/file3.txt' will beoverwritten with the contents of the corresponding files in the Cloud Storagebucket.

If instead we had run

gcloudalphacomposerenvironmentsstoragedataexportmyenv--source=subdir1/file3.txt--destination=/foo

the resulting local directory structure would be the following:

/foo|+--file1.txt+--file3.txt+--fileX.txt|||+--subdir1|||||+--file3.txt||+--fileY.txt

No local files would be overwritten since'gs://the-bucket/dags/subdir1/file3.txt' was written to '/foo/file3.txt' insteadof 'foo/subdir1/file3.txt'.
