ArmoniK.TaskReRunner 0.1.0-SNAPSHOT.116.b04e6af

Armonik.TaskReRunner

This project is part of the ArmoniK project. Armonik.Task.ReRunner is designed to simplify debugging by allowing users to rerun previously submitted and processed tasks. By providing services to select and re-execute individual tasks, it helps users identify and fix issues, streamlining the overall debugging process.

You can use your favorite IDE debugger on you worker with the ArmoniK.TaskReRunner.

Key Features

• Rerun Individual Tasks: Select and rerun individual ArmoniK tasks by providing their task IDs.

• Logging and Monitoring: Detailed logs and monitoring for each rerun operation to ensure debugging and transparency.

Installation

• Clone the repository and move into it.

  git clone git@github.com:aneoconsulting/ArmoniK.TaskReRunner.git
  cd ArmoniK.TaskReRunner
  

Prerequisites

To run the program, you need:

• To have a task that you want to rerun with its TaskId.
• To have a worker which failed.
• To extract the data from the task you want to rerun in the correct JSON format.

N.B.: You don't need ArmoniK to rerun a task, but you can't rerun a task without having already run it through ArmoniK.

Obtain Data in Json

Use the TaskDumper to extract Data from ArmoniK.

Run the TaskDumper program with your ArmoniK running.

• With the cloned repository :

dotnet run --project src/TaskDumper --endpoint <YOUR_ENDPOINT> --taskId <TASK_ID>

Replace <YOUR_ENDPOINT> with your control_plane_url.

Replace <TASK_ID> with TaskId of the task to retrieve.

Flags

• --endpoint: Endpoint for the connection to ArmoniK control plane.
• --taskId: TaskId of the task to retrieve.
• --dataFolder: Absolute path to the folder that will contain the binary data required to rerun the task.

Default Flag Values

• --endpoint: "http://localhost:5001".
• --taskId: "none".
• --dataFolder: The current directory + "ak_dumper_" + taskId. Example : " /mnt/c/Users/ereali/source/repos/ak_dumper_2bc1bd28-9082-45fd-9390-ac713682e038".

Debug Without Extracting Directly from ArmoniK

Create Your Own JSON

You can create a JSON yourself.

Here is a minimalist JSON with only the necessary variables for the HelloWorld Sample Example:

{
    "sessionId": "",
    "payloadId": "2bc1bd28-9082-45fd-9390-ac713682e038",
    "taskId": "",
    "taskOptions": {},
    "dataDependencies": [],
    "expectedOutputKeys": [
        "8cdc1510-2240-488e-bd5f-4df0969ef5e9"
    ],
    "dataFolder": "/mnt/c/Users/ereali/source/repos/ak_dumper_2bc1bd28-9082-45fd-9390-ac713682e038/Results",
    "configuration": {}
}

Put the values in files

• The payload data needs to be in a file named after the <PAYLOAD_ID>. This <PAYLOAD_ID> will be put in the PayloadId section of your JSON.
• The data dependencies need to be in files named after each <DATADEPENDENCIE_ID>. These <DATADEPENDENCIE_ID> will be put in the DataDependencies section of your JSON.

Create these files in the same folder and set its path in the dataFolder field of the JSON file.

Tree Example :

ak_dumper_2bc1bd28-9082-45fd-9390-ac713682e038
├── Results
    ├── PAYLOAD_ID
    └── DATADEPENDENCIE_ID

Start Your Worker

Create a directory with write access fot sockets.

mkdir /tmp/sockets
chmod 777 /tmp/sockets

Linux with the sockets path ComputePlane__WorkerChannel__Address=/tmp/sockets/worker.sock and ComputePlane__AgentChannel__Address=/tmp/sockets/agent.sock.

Here is a command line example to run a C# worker with the correct sockets:

ComputePlane__WorkerChannel__Address=/tmp/sockets/worker.sock \
ComputePlane__AgentChannel__Address=/tmp/sockets/agent.sock \
dotnet run --project <PATH_TO_PROJECT.CSPROJ>

Replace <PATH_TO_PROJECT.CSPROJ> with the path to your .csproj file.

Docker Htcmock through docker:

docker run --rm -d --name htcmock -u $(id -u) \
-e ComputePlane__WorkerChannel__Address=/cache/worker.sock \
-e ComputePlane__AgentChannel__Address=/cache/agent.sock \
-v /tmp/sockets:/cache -v <PATH_TO_BINARIES>:<PATH_TO_BINARIES> \
dockerhubaneo/armonik_core_htcmock_test_worker:<ARMONIK_VERSION_CORE>

Replace <PATH_TO_BINARIES> with the path to the extracted binary files.

Replace <ARMONIK_VERSION> with the current core version.

Usage

Rerun a Single Task

To rerun a single task, use the dotnet run command and provide the path of the JSON file containing task data as an argument:

dotnet run --path <DATA.JSON> --project src/TaskReRunner/

Replace <DATA.JSON> with the path to your JSON file.

Replace <PATH_TO_FOLDER> with the absolute path to your folder containing PayloadId and DataDependencies files.

Flags

• --path: Path to the JSON file containing the data needed to rerun the task.
• --force: Allow the previous output deletion.

Default Flag Values

• --path: "task.json".
• --force: false.

You can recover your results in <CURRRENT_DIRECTORY>/ak_dumper_<TASK_ID> or it will be printed on your console as: Notified result0 Data: <DATA_IN_BYTE>.
