gcloud composer environments storage dags export

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.

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'.

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.

To set the environment attribute:

• provide the argument --environment on the command line.

This flag argument must be specified if any of the other arguments in this group are specified.

--location=LOCATION

Region where Composer environment runs or in which to create the environment.

To set the location attribute:

• provide the argument --environment on the command line with a fully specified name;
• provide the argument --location on the command line;
• set the property composer/location.

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: --access-token-file, --account, --billing-project, --configuration, --flags-file, --flatten, --format, --help, --impersonate-service-account, --log-http, --project, --quiet, --trace-token, --user-output-enabled, --verbosity.
