Invoke Databricks Wheel TasksDatabricks Python Wheel dev tasks in a namespaced collection of tasks to enrich the Invoke CLI task runner.Invoke Databricks Wheel TasksGetting StartedDatabricks CLI ConfigConfig fileEnvironment VariablesInvoke SetupThe Tasksuploaddefine-jobrun-jobContributingResourcesPrior ArtGetting Startedpipinstallinvoke-databricks-wheel-tasksThis will also installinvokeanddatabricks-cli.Databricks CLI ConfigIt is assumed you will follow the documentation provided to setupdatabricks-cli.https://docs.databricks.com/dev-tools/cli/index.htmlThere are 2 options config file or environment variables.Config fileYou'll need to setup a Personal Access Token. Then run the following command:databricksconfigure--profileyourprofilename--token

DatabricksHost(shouldbeginwithhttps://):https://myorganisation.cloud.databricks.com/

jobs-api-version=2.1Environment VariablesOn some CI systems it is better to export secrets into environment variables rather than have config files with secrets on CI servers.Export the following and thedatabricks-cliwill pick it up:DATABRICKS_HOST=https://myorganisation.cloud.databricks.com/DATABRICKS_TOKEN=dapi0123456789abcdef0123456789abcdefDATABRICKS_JOBS_API_VERSION="2.1Invoke Setuptasks.pyfrominvokeimporttaskfrominvoke_databricks_wheel_tasksimport*# noqaOnce yourtasks.pyis setup like thisinvokewill have the extra commands:λinvoke--list

This project assumes you're usingpoetryor your wheel build output is located indist/.If you have other requirements thenpull requests welcome.define-jobYou may want to runinvoke --help define-jobto get the help documentation.There are a few arguments that get abbreviated which we will explain before discussing how they work together.--jinja-templateor-j: This is aJinja2 Templatethat must resolve to a validDatabricks Jobs JSON payloadspec.--config-fileor-c: This is either a JSON or YAML file to define the config, that gets used to parametrise the abovejinja-template. Thisconfig-filecan also be a Jinja template to inject values that can only be known at runtime like the git feature branch you are currently on. By default it is treated as a plain config file and not a Jinja Template unlessenvironment-variableflags are specified (see next).--environment-variableor-e: This flag can be repeated many times to specify multiple values. It takes a string in thekey=valueformat.Eg-e branch=$(git branch --show-current) -e main_wheel=$MAIN -e utils_wheel=$UTILSSo an example command could look like:invokedefine-job\-jjobs/base-job-template.json.j2\-cjobs/customer360-etl-job.yaml\-ebranch=$(gitbranch--show-current)\-emain_whl=$(invokedbfs-wheel-path)\-eutils_whl=$UTILS_DBFS_WHEEL_PATHThen the-evalues can get templated intocustomer360-etl-job.yml. Then that YAML file gets parsed and injected intobase-job-template.json.j2This will then check the list of Jobs in your workspace, see if a job with the same name exists already and perform acreate or replace joboperation. This expects theconfig-fileto have a keynameto be able to cross check the list of existing jobs.The beauty is that the specifics ofconfig-fileandjinja-templateis completely up to you.config-fileis the minimal datastructure you need to configurejinja-templateand you just use theJinja Control Structures(if-else,for-loop, etc) to traverse it and populatejinja-template.run-jobThis will create a manual trigger of your job withjob-id.The triggering returns arun-id, where thisrun-idgets polled until the state gets to an end state.Then a call todatabricks runs get-output --run-idhappens to retrieve anderror,error_traceand/orlogsto be emitted to console.ContributingAt all times, you have the power to fork this project, make changes as you see fit and then:pipinstallhttps://github.com/user/repository/archive/branch.zipStackoverflow: pip install from github branchThat way you can run from your own custom fork in the interim or even in-house your work and simply use this project as a starting point. That is totally ok.However if you would like to contribute your changes back, then open a Pull Request "across forks".Once your changes are merged and published you can revert to the canonical version ofpip installing this package.If you're not sure how to make changes or if you should sink the time and effort, then open an Issue instead and we can have a chat to triage the issue.Resourcespyinvokedatabricks-cliPrior Arthttps://github.com/Smile-SA/invoke-sphinxhttps://github.com/Dashlane/dbt-invoke
