  --batch                         [Deprecated in 2.7.0] Since v2.7.0, the
                                  default executor is AWSbatch so there is no
                                  need to use this flag. It is maintained for
                                  backwards compatibility.

Send a job to CloudOS

First, configure your local environment to ease parameters input. We will try to submit a small toy example already available.

MY_API_KEY="xxxxx"
CLOUDOS="https://cloudos.lifebit.ai"
WORKSPACE_ID="xxxxx"
PROJECT_NAME="API jobs"
WORKFLOW_NAME="rnatoy"
JOB_PARAMS="cloudos/examples/rnatoy.config"

As you can see, a file with the job parameters is used to configure the job. This file could be a regular nextflow.config file or any file with the following structure:

params {
    reads   = s3://lifebit-featured-datasets/pipelines/rnatoy-data
    genome  = s3://lifebit-featured-datasets/pipelines/rnatoy-data/ggal_1_48850000_49020000.Ggal71.500bpflank.fa
    annot   = s3://lifebit-featured-datasets/pipelines/rnatoy-data/ggal_1_48850000_49020000.bed.gff
}

To submit our job:

cloudos job run \
    --cloudos-url $CLOUDOS \
    --apikey $MY_API_KEY \
    --workspace-id $WORKSPACE_ID \
    --project-name "$PROJECT_NAME" \
    --workflow-name $WORKFLOW_NAME \
    --job-config $JOB_PARAMS \
    --resumable

In addition, parameters can also be specified using the command-line -p or --parameter. For instance, the previous command is equivalent to:

cloudos job run \
    --cloudos-url $CLOUDOS \
    --apikey $MY_API_KEY \
    --workspace-id $WORKSPACE_ID \
    --project-name "$PROJECT_NAME" \
    --workflow-name $WORKFLOW_NAME \
    --parameter reads=s3://lifebit-featured-datasets/pipelines/rnatoy-data \
    --parameter genome=s3://lifebit-featured-datasets/pipelines/rnatoy-data/ggal_1_48850000_49020000.Ggal71.500bpflank.fa \
    --parameter annot=s3://lifebit-featured-datasets/pipelines/rnatoy-data/ggal_1_48850000_49020000.bed.gff \
    --resumable

NOTE: options --job-config and --parameter are completely compatible and complementary, so you can use a --job-config and adding additional parameters using --parameter in the same call.

If everything went well, you should see something like:

Executing run...
	Job successfully launched to CloudOS, please check the following link: https://cloudos.lifebit.ai/app/jobs/62c83a1191fe06013b7ef355
	Your assigned job id is: 62c83a1191fe06013b7ef355
	Your current job status is: initializing
	To further check your job status you can either go to https://cloudos.lifebit.ai/app/jobs/62c83a1191fe06013b7ef355 or use the following command:
    cloudos job status \
        --apikey $MY_API_KEY \
        --cloudos-url https://cloudos.lifebit.ai \
        --job-id 62c83a1191fe06013b7ef355

As you can see, the current status is initializing. This will change while the job progresses. To check the status, just apply the suggested command.

Another option is to set the --wait-completion parameter, which run the same job run command but waiting for its completion:

cloudos job run \
    --cloudos-url $CLOUDOS \
    --apikey $MY_API_KEY \
    --workspace-id $WORKSPACE_ID \
    --project-name "$PROJECT_NAME" \
    --workflow-name $WORKFLOW_NAME \
    --job-config $JOB_PARAMS \
    --resumable \
    --wait-completion

When setting this parameter, you can also set --request-interval to a bigger number (default is 30s) if the job is quite large. This will ensure that the status requests are not sent too close from each other and recognized as spam by the API.

If the job takes less than --wait-time (3600 seconds by default), the previous command should have an output similar to:

Executing run...
	Job successfully launched to CloudOS, please check the following link: https://cloudos.lifebit.ai/app/jobs/62c83a6191fe06013b7ef363
	Your assigned job id is: 62c83a6191fe06013b7ef363
	Please, wait until job completion or max wait time of 3600 seconds is reached.
	Your current job status is: initializing.
	Your current job status is: running.
	Your job took 420 seconds to complete successfully.

Executor support

CloudOS supports AWS batch executor by default. You can specify the AWS batch queue to use, from the ones available in your workspace (see here) by specifying its name with the --job-queue parameter. If none is specified, the most recent suitable queue in your workspace will be selected by default. Example command:

cloudos job run \
    --cloudos-url $CLOUDOS \
    --apikey $MY_API_KEY \
    --workspace-id $WORKSPACE_ID \
    --project-name "$PROJECT_NAME" \
    --workflow-name $WORKFLOW_NAME \
    --job-config $JOB_PARAMS \
    --resumable

Note: from cloudos-cli 2.7.0, the default executor is AWS batch. The previous Apache ignite executor is being removed progressively from CloudOS, so most likely will not be available in your CloudOS. Cloudos-cli is still supporting ignite during this period, by adding the --ignite flag to the cloudos job run command. Please, note that if you use --ignite flag in a CloudOS without ignite support, the command fail.

Azure execution platform support

CloudOS can also be configured to use Microsoft Azure compute platforms. If your CloudOS is configured to use Azure, you will need to take into consideration the following:

When sending jobs to CloudOS using cloudos job run or cloudos job run-curated-examples commands, please use the option --execution-platform azure.
Due to the lack of AWS batch queues in Azure, cloudos queue list command is not working.

Other than that, cloudos-cli will work very similarly. For instance, this is a typical send job command:

cloudos job run \
    --cloudos-url $CLOUDOS \
    --apikey $MY_API_KEY \
    --workspace-id $WORKSPACE_ID \
    --project-name "$PROJECT_NAME" \
    --workflow-name $WORKFLOW_NAME \
    --job-config $JOB_PARAMS \
    --resumable \
    --execution-platform azure

HPC execution support

CloudOS is also prepared to use an HPC compute infrastructure. For such cases, you will need to take into account the following for your job submissions using cloudos job run command:

Use the following parameter: --execution-platform hpc.
Indicate the HPC ID using: --hpc-id XXXX.

Example command:

cloudos job run \
    --cloudos-url $CLOUDOS \
    --apikey $MY_API_KEY \
    --workspace-id $WORKSPACE_ID \
    --project-name "$PROJECT_NAME" \
    --workflow-name $WORKFLOW_NAME \
    --job-config $JOB_PARAMS \
    --execution-platform hpc \
    --hpc-id $YOUR_HPC_ID

Please, note that HPC execution do not support the following parameters and all of them will be ignored:

--job-queue
--resumable | --do-not-save-logs
--instance-type | --instance-disk | --cost-limit
--storage-mode | --lustre-size
--wdl-mainfile | --wdl-importsfile | --cromwell-token

Check job status

To check the status of a submitted job, just use the suggested command:

cloudos job status \
    --apikey $MY_API_KEY \
    --cloudos-url $CLOUDOS \
    --job-id 62c83a1191fe06013b7ef355

The expected output should be something similar to:

Executing status...
	Your current job status is: completed

	To further check your job status you can either go to https://cloudos.lifebit.ai/app/jobs/62c83a1191fe06013b7ef355 or repeat the command you just used.

Get a list of your jobs from a CloudOS workspace

You can get a summary of your last 30 submitted jobs (or your selected number of last jobs using --last-n-jobs n parameter) in two different formats:

CSV: this is a table with a minimum predefined set of columns by default, or all the available columns using the --all-fields argument.
JSON: all the available information from your jobs, in JSON format.

To get a list with your last 30 submitted jobs to a given workspace, in CSV format, use the following command:

cloudos job list \
    --cloudos-url $CLOUDOS \
    --apikey $MY_API_KEY \
    --workspace-id $WORKSPACE_ID \
    --output-format csv \
    --all-fields

The expected output is something similar to:

Executing list...
	Job list collected with a total of 30 jobs.
	Job list saved to joblist.csv

In addition, a file named joblist.csv is created.

To get the same information, but for all your jobs and in JSON format, use the following command:

cloudos job list \
    --cloudos-url $CLOUDOS \
    --apikey $MY_API_KEY \
    --workspace-id $WORKSPACE_ID \
    --last-n-jobs all \
    --output-format json

Executing list...
	Job list collected with a total of 276 jobs.
	Job list saved to joblist.json

Get a list of all available workflows from a CloudOS workspace

You can get a summary of all the available workspace workflows in two different formats:

CSV: this is a table with a minimum predefined set of columns by default, or all the available columns using the --all-fields parameter.
JSON: all the available information from workflows, in JSON format.

To get a CSV table with all the available workflows for a given workspace, use the following command:

cloudos workflow list \
    --cloudos-url $CLOUDOS \
    --apikey $MY_API_KEY \
    --workspace-id $WORKSPACE_ID \
    --output-format csv \
    --all-fields

The expected output is something similar to:

Executing list...
	Workflow list collected with a total of 609 workflows.
	Workflow list saved to workflow_list.csv

To get the same information, but in JSON format, use the following command:

cloudos workflow list \
    --cloudos-url $CLOUDOS \
    --apikey $MY_API_KEY \
    --workspace-id $WORKSPACE_ID \
    --output-format json

Executing list...
	Workflow list collected with a total of 609 workflows.
	Workflow list saved to workflow_list.json

Normally, collected workflows are those that can be found in "WORKSPACE TOOLS" section in CloudOS. By using --curated flag, the collected workflows will instead include "CURATED PIPELINES & TOOLS" only.

cloudos workflow list \
    --cloudos-url $CLOUDOS \
    --apikey $MY_API_KEY \
    --workspace-id $WORKSPACE_ID \
    --curated

Executing list...
	Workflow list collected with a total of 73 workflows.
	Workflow list saved to workflow_list.csv

Import a Nextflow workflow to a CloudOS workspace

You can import new workflows to your CloudOS workspaces. The only requirements are:

The workflow is a Nextflow pipeline.
The workflow repository is located at GitHub or Bitbucket server.
If your repository is private, you have access to the repository and you have linked your GitHub or Bitbucket server accounts to CloudOS.
You have got the repository_id and the repository_project_id.

How to get repository_id and repository_project_id from a GitHub repository

Option 1: searching in the page source code

Go to the repository URL. Click on the right button of your mouse to get the following menu and click on "View Page Source".

For collecting the repository_project_id, search for octolytics-dimension-user_id string in the source code. The content value is your repository_project_id (30871219 in the example image).

For collecting the repository_id, search for octolytics-dimension-repository_id string in the source code. The content value is your repository_id (122059362 in the example image).

Option 2: using github CLI

If you have access to the repository, you can use the following tools to collect the required values:

gh
jq

For collecting the repository_project_id:

# If your repo URL is https://github.com/lifebit-ai/DeepVariant
OWNER="lifebit-ai"
REPO="DeepVariant"
repository_project_id=$(gh api -H "Accept: application/vnd.github+json" repos/$OWNER/$REPO | jq .owner.id)
echo $repository_project_id
30871219

For collecting the repository_id:

# If your repo URL is https://github.com/lifebit-ai/DeepVariant
OWNER="lifebit-ai"
REPO="DeepVariant"
repository_id=$(gh api -H "Accept: application/vnd.github+json" repos/$OWNER/$REPO | jq .id)
echo $repository_id
122059362

How to get repository_project_id from a Bitbucket server repository

For Bitbucket server repositories, only repository_project_id is required. To collect it:

Option 1: using the REST API from your browser

Create a REST API URL from your repo URL by adding /rest/api/latest to the URL:

Original URL: https://bitbucket.com/projects/MYPROJECT/repos/my-repo
REST API URL: https://bitbucket.com/rest/api/latest/projects/MYPROJECT/repos/my-repo

IMPORTANT NOTE: Please, as your repository original URL, do not use the "clone" URL provided by Bitbucket (the one with .git extension), use the actual browser URL, removing the terminal /browse.

Use the REST API URL in a browser and it will generate a JSON output.
Your repository_project_id is the value of the project.id field.

Option 2: using cURL

If you have access to the repository, you can use the following tools to collect the required value:

cURL
jq

For collecting the repository_project_id:

BITBUCKET_TOKEN="xxx"
repository_project_id=$(curl https://bitbucket.com/rest/api/latest/projects/MYPROJECT/repos/my-repo -H "Authorization: Bearer $BITBUCKET_TOKEN" | jq .project.id)
echo $repository_project_id
1234

Usage of the workflow import command

To import GitHub workflows to CloudOS, you can use the following command:

# Example workflow to import: https://github.com/lifebit-ai/DeepVariant
WORKFLOW_URL="https://github.com/lifebit-ai/DeepVariant"

# You will need the repository_project_id and repository_id values explained above
REPOSITORY_PROJECT_ID=30871219
REPOSITORY_ID=122059362

cloudos workflow import \
    --cloudos-url $CLOUDOS \
    --apikey $MY_API_KEY \
    --workspace-id $WORKSPACE_ID \
    --workflow-url $WORKFLOW_URL \
    --workflow-name "new_name_for_the_github_workflow" \
    --repository-project-id $REPOSITORY_PROJECT_ID \
    --repository-id $REPOSITORY_ID

The expected output will be:

CloudOS workflow functionality: list and import workflows.

Executing workflow import...

	[Message] Only Nextflow workflows are currently supported.

	Workflow test_import_github_3 was imported successfully with the following ID: 6616a8cb454b09bbb3d9dc20

Optionally, you can add a link to your workflow documentation by providing the URL using the parameter --workflow-docs-link. E.g.:

cloudos workflow import \
    --cloudos-url $CLOUDOS \
    --apikey $MY_API_KEY \
    --workspace-id $WORKSPACE_ID \
    --workflow-url $WORKFLOW_URL \
    --workflow-name "new_name_for_the_github_workflow" \
    --workflow-docs-link "https://github.com/lifebit-ai/DeepVariant/blob/master/README.md" \
    --repository-project-id $REPOSITORY_PROJECT_ID \
    --repository-id $REPOSITORY_ID

To import bitbucket server workflows, --repository-id parameter is not required:

WORKFLOW_URL="https://bitbucket.com/projects/MYPROJECT/repos/my-repo"

# You will need only the repository_project_id
REPOSITORY_PROJECT_ID=1234

cloudos workflow import \
    --cloudos-url $CLOUDOS \
    --apikey $MY_API_KEY \
    --workspace-id $WORKSPACE_ID \
    --workflow-url $WORKFLOW_URL \
    --workflow-name "new_name_for_the_bitbucket_workflow" \
    --repository-project-id $REPOSITORY_PROJECT_ID

NOTE: please, take into account that importing workflows using cloudos-cli is not yet available in all the CloudOS workspaces. If you try to use this feature in a non-prepared workspace you will get the following error message: It seems your API key is not authorised. Please check if your workspace has support for importing workflows using cloudos-cli.

Get a list of all available projects from a CloudOS workspace

Similarly to the workflows functionality, you can get a summary of all the available workspace projects in two different formats:

CSV: this is a table with a minimum predefined set of columns by default, or all the available columns using the --all-fields parameter.
JSON: all the available information from projects, in JSON format.

To get a CSV table with all the available projects for a given workspace, use the following command:

cloudos project list \
    --cloudos-url $CLOUDOS \
    --apikey $MY_API_KEY \
    --workspace-id $WORKSPACE_ID \
    --output-format csv \
    --all-fields

The expected output is something similar to:

Executing list...
	Workflow list collected with a total of 320 projects.
	Workflow list saved to project_list.csv

Run all Curated Workflows with example parameters

In "Pipelines" section in CloudOS, there is a special type of workflows called "CURATED PIPELINES & TOOLS". These workflows are curated and maintained by our team. Some of them also offer the possibility of testing them using example parameters. We have added the following CLI functionality to be able to run all of these curated workflows with example parameters.

The following example will launch all the workspace curated workflows with example parameters:

cloudos job run-curated-examples \
    --cloudos-url $CLOUDOS \
    --apikey $MY_API_KEY \
    --workspace-id $WORKSPACE_ID \
    --project-name "$PROJECT_NAME"

    All 39 curated job launched successfully!

You can also wait for all jobs completion and get a final summary of their status using the --wait-completion flag:

cloudos job run-curated-examples \
    --cloudos-url $CLOUDOS \
    --apikey $MY_API_KEY \
    --workspace-id $WORKSPACE_ID \
    --project-name "$PROJECT_NAME" \
    --wait-completion

NOTE: currently, this command only runs Nextflow curated workflows.

Get a list of the available job queues

Job queues are required for running jobs using AWS batch executor. The available job queues in your CloudOS workspace are listed in the "Compute Resources" section in "Settings". You can get a summary of all the available workspace job queues in two formats:

CSV: this is a table with a selection of the available job queue information. Alternatively, you can get all the information using the --all-fields flag.
JSON: all the available information from job queues, in JSON format.

Example command: getting all available job queues in JSON format.

cloudos queue list \
    --cloudos-url $CLOUDOS \
    --apikey $MY_API_KEY \
    --workspace-id $WORKSPACE_ID \
    --output-format json \
    --output-basename "available_queues"

Executing list...
	Job queue list collected with a total of 5 queues.
	Job queue list saved to available_queues.json

NOTE: the job name that is visible in CloudOS and has to be used in combination with --job-queue parameter is the one in label field.

WDL pipeline support

Cromwell server managing

In order to run WDL pipelines, a Cromwell server in CloudOS should be running. This server can be accessed to check its status, restart it or stop it, using the following commands:

# Check Cromwell status
cloudos cromwell status \
    --cloudos-url $CLOUDOS \
    --apikey $MY_API_KEY \
    --workspace-id $WORKSPACE_ID

Executing status...
	Current Cromwell server status is: Stopped

# Cromwell start
cloudos cromwell start \
    --cloudos-url $CLOUDOS \
    --apikey $MY_API_KEY \
    --workspace-id $WORKSPACE_ID

Starting Cromwell server...
	Current Cromwell server status is: Initializing

	Current Cromwell server status is: Running

# Cromwell stop
cloudos cromwell stop \
    --cloudos-url $CLOUDOS \
    --apikey $MY_API_KEY \
    --workspace-id $WORKSPACE_ID

Stopping Cromwell server...
	Current Cromwell server status is: Stopped

Running WDL workflows

To run WDL workflows, cloudos job run command can be used normally, but adding two extra parameters:

--wdl-mainfile: name of the mainFile (*.wdl) file used by the CloudOS workflow.
--wdl-importsfile [Optional]: name of the worfklow imported file (importsFile, *.zip).

All the rest of the cloudos job run functionality is available.

NOTE: WDL does not support profiles and therefore, --nextflow-profile option is not available. Instead, use --job-config and/or --parameter. The format of the job config file is expected to be the same as for nextflow pipelines.

Example of job config file for WDL workflows:

params {
 test.hello.name = aasdajdad
  test.bye.nameTwo = asijdadads
  test.number.x = 2
  test.greeter.morning = true
  test.wf_hello_in = bomba
  test.arrayTest = ["lala"]
  test.mapTest = {"some":"props"}
}

NOTE: when using --parameter option, if the value needs quotes (") you will need to escape them. E.g.: --parameter test.arrayTest=[\"lala\"]

# Configure variables
MY_API_KEY="xxxxx"
CLOUDOS="https://cloudos.lifebit.ai"
WORKSPACE_ID="xxxxx"
PROJECT_NAME="wdl-test"
WORKFLOW_NAME="wdl- test"
MAINFILE="hello.wdl"
IMPORTSFILE="imports_7mb.zip"
JOB_PARAMS="cloudos/examples/wdl.config"

# Run job
cloudos job run \
  --cloudos-url $CLOUDOS \
  --apikey $MY_API_KEY \
  --workspace-id $WORKSPACE_ID \
  --project-name $PROJECT_NAME \
  --workflow-name "$WORKFLOW_NAME" \
  --wdl-mainfile $MAINFILE \
  --wdl-importsfile $IMPORTSFILE \
  --job-config $JOB_PARAMS \
  --wait-completion

    *******************************************************************************
    [WARNING] Cromwell server is now running. Plase, remember to stop it when your
    job finishes. You can use the following command:
    cloudos cromwell stop \
        --cromwell-token $CROMWELL_TOKEN \
        --cloudos-url $CLOUDOS \
        --workspace-id $WORKSPACE_ID
    *******************************************************************************

	Job successfully launched to CloudOS, please check the following link: ****
	Your assigned job id is: ****
	Please, wait until job completion or max wait time of 3600 seconds is reached.
	Your current job status is: initializing.
	Your current job status is: running.
	Your job took 60 seconds to complete successfully.

Import the functionality to your own python scripts

To illustrate how to import the package and use its functionality inside your own python scripts, we will perform a job submission and check its status from inside a python script.

Again, we will set up the environment to ease the work:

import cloudos.jobs.job as jb
import json


# GLOBAL VARS.
apikey = 'xxxxx'
cloudos_url = 'https://cloudos.lifebit.ai'
workspace_id = 'xxxxx'
project_name = 'API jobs'
workflow_name = 'rnatoy'
job_config = 'cloudos/examples/rnatoy.config'

First, create the Job object:

j = jb.Job(cloudos_url, apikey, None, workspace_id, project_name, workflow_name)
print(j)

Then, send the job:

j_id = j.send_job(job_config)

To check the status:

j_status = j.get_job_status(j_id)
j_status_h = json.loads(j_status.content)["status"]
print(j_status_h)

The status will change while your job progresses, so to check again just repeat the above code.

You can also collect your last 30 submitted jobs for a given workspace using the following command.

my_jobs_r = j.get_job_list(workspace_id)
my_jobs = j.process_job_list(my_jobs_r)
print(my_jobs)

Or inspect all the available workflows for a given workspace using the following command.

my_workflows_r = j.get_workflow_list(workspace_id)
my_workflows = j.process_workflow_list(my_workflows_r)
print(my_workflows)

Similarly, you can inspect all the available projects for a given workspace using the following command.

my_projects_r = j.get_project_list(workspace_id)
my_projects = j.process_project_list(my_projects_r)
print(my_projects)

Running WDL pipelines using your own scripts

You can even run WDL pipelines. First check the Cromwell server status and restart it if Stopped:

import cloudos.clos as cl
import cloudos.jobs.job as jb
import json


# GLOBAL VARS.
apikey = 'xxxxx'
cloudos_url = 'https://cloudos.lifebit.ai'
workspace_id = 'xxxxx'
project_name = 'wdl-test'
workflow_name = 'wdl- test'
mainfile = 'hello.wdl'
importsfile = 'imports_7mb.zip'
job_config = 'cloudos/examples/wdl.config'

# First create cloudos object
cl = cl.Cloudos(cloudos_url, apikey, None)

# Then, check Cromwell status
c_status = cl.get_cromwell_status(workspace_id)
c_status_h = json.loads(c_status.content)["status"]
print(c_status_h)

# Start Cromwell server
cl.cromwell_switch(workspace_id, 'restart')

# Check again Cromwell status (wait until status: 'Running')
c_status = cl.get_cromwell_status(workspace_id)
c_status_h = json.loads(c_status.content)["status"]
print(c_status_h)

# Send a job (wait until job has status: 'Completed')
j = jb.Job(cloudos_url, apikey, None, workspace_id, project_name, workflow_name, True, mainfile,
           importsfile)
j_id = j.send_job(job_config, workflow_type='wdl', cromwell_id=json.loads(c_status.content)["_id"])
j_status = j.get_job_status(j_id)
j_status_h = json.loads(j_status.content)["status"]
print(j_status_h)

# Stop Cromwell server
cl.cromwell_switch(workspace_id, 'stop')

# Check again Cromwell status
c_status = cl.get_cromwell_status(workspace_id)
c_status_h = json.loads(c_status.content)["status"]
print(c_status_h)
