NAME

: gcloud composer environments storage dags export - export DAGs from an environment into local storage or Cloud Storage

SYNOPSIS

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

DESCRIPTION

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 DAGs 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.

REQUIRED FLAGS

--destination=DESTINATION

The path to an existing local directory or a Cloud Storage bucket/directory into which to export files.

Environment resource - The environment from whose Cloud Storage bucket to export DAGs. The arguments in this group can be used to specify the attributes of this resource. (NOTE) Some attributes are not given arguments in this group but can be set in other ways. To set the [project] attribute: provide the argument [--environment] on the command line with a fully specified name; provide the argument [--project] on the command line; set the property [core/project]. This must be specified.

--environment=ENVIRONMENT: ID of the environment or fully qualified identifier for the environment. This flag must be specified if any of the other arguments in this group are specified.
--location=LOCATION: Compute Engine region in which to create the environment.

OPTIONAL FLAGS

--source=SOURCE: An optional relative path to a file or directory to be exported from the dags/ subdirectory in the environment's Cloud Storage bucket.

GCLOUD WIDE FLAGS

These flags are available to all commands: --account, --configuration, --flags-file, --flatten, --format, --help, --log-http, --project, --quiet, --trace-token, --user-output-enabled, --verbosity. Run $ gcloud help for details.

EXAMPLES

Suppose the environment myenv's Cloud Storage bucket has the following structure:

: gs://the-bucket | +-- dags | | | +-- file1.py | +-- file2.py | | | +-- subdir1 | | | | | +-- file3.py | | +-- file4.py

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

: /foo | +-- file1.py +-- fileX.py | | | +-- subdir1 | | | | | +-- file3.py | | +-- fileY.py

The following command:

: gcloud composer environments storage dags export myenv --destination /foo

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

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

The local files '/foo/file1.py' and '/foo/subdir1/file3.py' will be overwritten with the contents of the corresponding files in the Cloud Storage bucket.
If instead we had run

: gcloud composer environments storage dags export myenv --source subdir1/file3.py --destination /foo

the resulting local directory structure would be the following:

: /foo | +-- file1.py +-- file3.py +-- fileX.py | | | +-- subdir1 | | | | | +-- file3.py | | +-- fileY.py

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

NOTES

These variants are also available:

: $ gcloud alpha composer environments storage dags export $ gcloud beta composer environments storage dags export
