gcloud alpha composer environments storage data export

NAME
gcloud alpha composer environments storage data export - export data from an environment into local storage or Cloud Storage
SYNOPSIS
gcloud alpha composer environments storage data export --destination=DESTINATION (--environment=ENVIRONMENT : --location=LOCATION) [--source=SOURCE] [GCLOUD_WIDE_FLAG …]
DESCRIPTION
(ALPHA) If the SOURCE is a directory, it and its contents are are exported recursively. If no SOURCE is provided, the entire contents of the environment's data directory will be exported. Colliding files in the DESTINATION will be overwritten. If a file exists in the DESTINATION but there is no corresponding file to overwrite it, it is untouched.
EXAMPLES
Suppose the environment myenv's Cloud Storage bucket has the following structure: 
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: 

gcloud alpha composer environments storage data export myenv --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 be overwritten with the contents of the corresponding files in the Cloud Storage bucket.

If instead we had run 

gcloud alpha composer environments storage data export myenv --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' instead of 'foo/subdir1/file3.txt'.
