Cromshell

Cromshell is a CLI for submitting workflows to a Cromwell server and monitoring/querying their results.

Examples:

         cromshell submit workflow.wdl inputs.json options.json dependencies.zip
         cromshell status
         cromshell -t 20 metadata
         cromshell logs -2

Supported Options:

• --no_turtle or --I_hate_turtles
  • Hide turtle logo
• --cromwell_url [TEXT]
  • Specifies Cromwell URL used.
  • TEXT Example: http://65.61.654.8:8000
  • Note: Depending on your Cromwell server configuration, you may not need to specify the port.
• -t [TIMEOUT]
  • Specifies the server connection timeout in seconds.
  • Default is 5 sec.
  • TIMEOUT must be a positive integer.
• --gcloud_token_email [TEXT]
  • Call gcloud auth print-access-token with this email and add the token as an auth header to requests.
• --referer_header_url [TEXT]
  • For servers that require a referer, supply this URL in the Referer: header.

Supported Subcommands:

Start/Stop workflows

• submit [-w] <wdl> <inputs_json> [options_json] [included_wdl_zip_file]
  • Automatically validates the WDL and JSON file.
  • Submit a new workflow to the Cromwell server.
  • -w [COMING SOON] Wait for workflow to transition from 'Submitted' to some other status before ${SCRIPTNAME} exits.
  • included_wdl_zip_file Zip file containing any WDL files included in the input WDL
• abort [workflow-id] [[workflow-id]...]
  • Abort a running workflow.

Workflow information:

• alias <workflow-id> <alias_name>
  • Label the given workflow ID with the given alias_name. Aliases can be used in place of workflow IDs to reference jobs.
  • Remove an alias by passing empty double quotes as alias_name (e.g. alias <workflow-id> "")

Query workflow status:

• status [workflow-id] [[workflow-id]...]
  • Check the status of a workflow.
• metadata [workflow-id] [[workflow-id]...]
  • Get the full metadata of a workflow.
• slim-metadata [workflow-id] [[workflow-id]...]
  • Get a subset of the metadata from a workflow.
• counts [-j] [-x] [workflow-id] [[workflow-id]...]
  • Get the summarized status of all jobs in the workflow.
  • -j prints a JSON instead of a pretty summary of the execution status (compresses subworkflows)
  • -x compress sub-workflows for less detailed summarization
• timing [workflow-id] [[workflow-id]...]
  • Open the timing diagram in a browser.

Logs

• logs [workflow-id] [[workflow-id]...]
  • List the log files produced by a workflow.
• [COMING SOON] fetch-logs [workflow-id] [[workflow-id]...]
  • Download all logs produced by a workflow.

Job Outputs

• list-outputs [workflow-id] [[workflow-id]...]
  • List all output files produced by a workflow.
• [COMING SOON] fetch-all [workflow-id] [[workflow-id]...]
  • Download all output files produced by a workflow.

Display a list jobs submitted through cromshell

• list [-c] [-u]
  • -c Color the output by completion status.
  • -u Check completion status of all unfinished jobs.

Clean up local cached list

• [COMING SOON] cleanup [-s STATUS]
  • Remove completed jobs from local list. This command removes all jobs from the local list that are in a completed state, where a completed state is one of: Succeeded, Failed, Aborted
  • -s [STATUS] If provided, will only remove jobs with the given [STATUS] from the local list.

Update cromwell server

• update-server
  • Change the cromwell server that new jobs will be submitted to.

Get cost for a workflow

• cost [-c] [-d] [workflow-id] [[workflow-id]...]
  • Get the cost for a workflow.
  • Only works for workflows that completed more than 24 hours ago on GCS. See Google Cost Exporting Documentation
  • Billing export to BigQuery must be enabled for your GCP billing project. See Setup billing data export to BigQuery.
  • Requires the bq_cost_table key to exist in the cromshell configuration file and have a value equal to the BigQuery cost table for your GCP billing project.
  • -c/--color Color outliers in task level cost results.
  • -d/--detailed Get the cost for a workflow at the task level.

Features:

• Running submit will create a new folder in the ~/.cromshell/${CROMWELL_URL}/ directory named with the cromwell job id of the newly submitted job.
  It will copy your wdl and json inputs into the folder for reproducibility.
• It keeps track of your most recently submitted jobs by storing their ids in ./cromshell/
  You may omit the job ID of the last job submitted when running commands, or use negative numbers to reference previous jobs, e.g. "-1" will track the last job, "-2" will track the one before that, and so on.
• You can override the default cromwell server by setting the argument --cromwell_url to the appropriate URL.
• You can override the default cromshell configuration folder by setting the environmental variable CROMSHELL_CONFIG to the appropriate directory.
• Most commands takes multiple workflow-ids, which you can specify both in relative and absolute ID value (i.e. cromshell status -- -1 -2 -3 c2db2989-2e09-4f2c-8a7f-c3733ae5ba7b).
• Assign aliases to workflow ids using the alias command (i.e. cromshell alias -- -1 myAliasName). Once the Alias command is used to attach an alias to a workflow id, the alias name can be used instead of the id (i.e. cromshell status myAliasName).

Legacy Cromshell

The original Cromshell shell script is still available in the legacy_cromshell folder and in the cromshell1 branch of this repository. It is no longer maintained, but is still available for use. The original Cromshell contains some commands not yet available in Cromshell2, such as fetch-logs, fetch-all, notify, and cleanup. These commands will be added to Cromshell2 in the future.
