This library provides bindings for the Domino APIs. It ships with the Domino Standard Environment (DSE).
See this documentation for details about the APIs:
- [Latest public Domino
APIs](https://docs.dominodatalab.com/en/latest/api_guide/8c929e/domino-public-apis/)
- [Legacy APIs](https://dominodatalab.github.io/api-docs/)
The latest released version of `python-domino` is `1.2.3`.
# Version compatibility matrix
The `python-domino` library is compatible with different versions of
Domino:
| Domino Versions | Python-Domino |
|-----------------|:-----------------------------------------------------------------------------------:|
| 3.6.x or lower | [0.3.5](http://github.com/dominodatalab/python-domino/archive/0.3.5.zip) |
| 4.1.0 or higher | [1.0.0](https://github.com/dominodatalab/python-domino/archive/1.0.0.zip) or Higher |
| 5.3.0 or higher | [1.2.0](https://github.com/dominodatalab/python-domino/archive/1.2.1.zip) or Higher |
| 5.5.0 or higher | [1.2.2](https://github.com/dominodatalab/python-domino/archive/1.2.2.zip) or Higher |
# Development
The current `python-domino` is based on Python 3.9, which is therefore recommended for development. `Pipenv` is also recommended to manage the dependencies.
To use the Python binding in a Domino workbook session, include `dominodatalab` in your project's requirements.txt file.
This makes the Python binding available for each new workbook session (or batch run) started within the project.
To install dependencies from `setup.py` for development:
pipenv install -e ".[dev]"
Use the same process for Airflow and data:
pipenv install -e ".[data]" ".[airflow]"
# Set up the connection
You can set up the connection by creating a new instance of `Domino`:
_class_ Domino(project, api_key=None, host=None, domino_token_file=None, auth_token=None)
- *project:* A project identifier (in the form of ownerusername/projectname).
- *api_proxy:* (Optional) Location of the Domino API reverse proxy as host:port.
If set, this proxy is used to intercept any Domino API requests and insert an authentication token.
_This is the preferred method of authentication_.
Alternatively, set the `DOMINO_API_PROXY` environment variable.
In Domino 5.4.0 or later, this variable is set inside a Domino run container.
NOTE: This mechanism does not work when connecting to an HTTPS endpoint; it is meant to be used inside Domino runs.
- *api_key:* (Optional) An API key to authenticate with.
If not provided, the library expects to find one in the `DOMINO_USER_API_KEY` environment variable.
If you are using the Python package in code that is already running in Domino, the `DOMINO_API_USER_KEY` variable is set automatically to be the key for the user who started the run.
- *host:* (Optional) A host URL.
If not provided, the library expects to find one in the `DOMINO_API_HOST` environment variable.
- *domino_token_file:* (Optional) Path to the Domino token file
containing the auth token.
If not provided, the library expects to find one in the `DOMINO_TOKEN_FILE` environment variable.
If you are using Python package in code that is already running in Domino, the `DOMINO_TOKEN_FILE` is set automatically to be the token file for the user who started the run.
- *auth_token:* (Optional) Authentication token.
## Authentication
Domino looks for the authentication method in the following order and uses the first one it finds:
1. `api_proxy`
2. `auth_token`
3. `domino_token_file`
4. `api_key`
5. `DOMINO_API_PROXY`
6. `DOMINO_TOKEN_FILE`
7. `DOMINO_USER_API_KEY`
The API proxy is the preferred method of authentication.
See
[Use the API Proxy to Authenticate Calls to the Domino API](https://docs.dominodatalab.com/en/latest/api_guide/ddf8eb).
## Additional environment variables
- `DOMINO_LOG_LEVEL`
The default log level is `INFO`.
You can change the log level by setting `DOMINO_LOG_LEVEL`, for example to `DEBUG`.
- `DOMINO_VERIFY_CERTIFICATE`
For testing purposes and issues with SSL certificates, set `DOMINO_VERIFY_CERTIFICATE` to `false`.
Be sure to unset this variable when not in use.
# Methods
## Projects
See
[`example_projects_usage.py`](https://github.com/dominodatalab/python-domino/blob/release-1.2.2/examples/example_projects_usage.py)
for example code.
### project_create(project_name, owner_username=None)

## Project tags
Project tags are an easy way to add freeform metadata to a project. Tags
help colleagues and consumers organize and find the Domino projects that
interest them. Tags can be used to describe the subject explored by a
project, the packages and libraries it uses, or the source of the data
within.

## Datasets
A Domino dataset is a collection of files that are available in user
executions as a filesystem directory. A dataset always reflects the most
recent version of the data. You can modify the contents of a dataset
through the Domino UI or through workload executions.
See [Domino
Datasets](https://docs.dominodatalab.com/en/latest/user_guide/0a8d11/datasets-overview/)
for more details, and

delete. NOTE: Datasets are first marked for deletion, then deleted
after a grace period (15 minutes, configurable). A Domino admin may
also need to complete this process before the name can be reused.
# Airflow
The `python-domino` client comes bundled with an
[Operator](https://airflow.apache.org/docs/apache-airflow/stable/concepts/operators.html)
for use with [Apache Airflow](https://airflow.apache.org/) as an extra.
When installing the client from PyPI, add the `airflow` flag to extras:
pip install "dominodatalab[airflow]"
Similarly, when installing the client from GitHub, use the following
command:
pip install -e git+https://github.com/dominodatalab/python-domino.git@1.0.6#egg="dominodatalab[airflow]"
See also
[example_airflow_dag.py](https://github.com/dominodatalab/python-domino/blob/release-1.2.1/examples/example_airflow_dag.py)
for example code.
## DominoOperator
from domino.airflow import DominoOperator
Allows a user to schedule Domino executions via Airflow. Follows the
same function signature as `domino.runs_start` with two extra arguments:
- `startup_delay: Optional[int] = 10` | Add a startup delay to your job, useful if you want to delay execution until after other work finishes.
- `include_setup_log: Optional[bool] = True` | Determine whether or not to publish the setup log of the job as the log prefix before `stdout`.
## DominoSparkOperator
from domino.airflow import DominoSparkOperator
Allows a user to schedule Domino executions via the v4 API, which
supports `onDemandSparkClusters`. Follows the same function signature as
`domino.job_start`, with the addition of `startup_delay` from above.
# Example
from domino import Domino
# By and large your commands will run against a single project,
# so you must specify the full project name
domino = Domino("chris/canon")
# List all runs in the project, most-recently queued first
all_runs = domino.runs_list()['data']
latest_100_runs = all_runs[0:100]
print(latest_100_runs)
# all runs have a commitId (the snapshot of the project when the
# run starts) and, if the run completed, an "outputCommitId"
# (the snapshot of the project after the run completed)
most_recent_run = all_runs[0]
commitId = most_recent_run['outputCommitId']
# list all the files in the output commit ID -- only showing the
# entries under the results directory. If not provided, will
# list all files in the project. Or you can say path=“/“ to
# list all files
files = domino.files_list(commitId, path='results/')['data']
for file in files:
print file['path'], '->', file['url']
print(files)
# Get the content (i.e. blob) for the file you're interested in.
# blobs_get returns a connection rather than the content, because
# the content can get quite large and it's up to you how you want
# to handle it
print(domino.blobs_get(files[0]['key']).read())
# Start a run of file main.py using the latest copy of that file
domino.runs_start(["main.py", "arg1", "arg2"])
# Start a "direct" command
domino.runs_start(["echo 'Hello, World!'"], isDirect=True)
# Start a run of a specific commit
domino.runs_start(["main.py"], commitId="aabbccddee")
# Manual installation
Because `python-domino` ships with the DSE, normally you do not need to install it.
This section provides instructions for installing it in another environment or updating it to a newer version.
Starting from version `1.0.6`, `python-domino` is available on PyPI as `dominodatalab`:
pip install dominodatalab
If you are adding install instructions for `python-domino` to your [Domino Environment](https://support.dominodatalab.com/hc/en-us/articles/115000392643-Compute-Environment-Management) Dockerfile Instructions field, you must add `RUN` to the beginning:
RUN pip install dominodatalab
To install a specific version of the library from PyPI, such as `1.0.6`:
pip install dominodatalab==1.0.6
To install a specific version of the library from GitHub, such as
`1.0.6`:
pip install https://github.com/dominodatalab/python-domino/archive/1.0.6.zip
