How to implement a Sitecore Commerce Minion

Question

I am new to Sitecore commerce Minions.

I wanted to create a Minion which runs for every 30 minutes to update the Product values.

I am getting the Products properties from external source.

What changes do I need to make ?

Answer 1

First of all you need to declare your minion on the environment definition for your minions environment.

In the Sitecore.Commerce.Engine project is the JSON file PlugIn.Habitat.CommerceMinions-1.0.0.json which is the definition for the habitat minions environment. This is the active environment on the commerce minions web site (one of 4 in IIS installed as part of commerce).

First of all you need to declare your minion in a json :

{
    "$type": "Sitecore.Commerce.Core.MinionPolicy, Sitecore.Commerce.Core",
    "WakeupInterval": "00:05:00",
    "ListToWatch": "",
    "FullyQualifiedName": "Plugin.MyProject.Import.ImportMinion, Plugin.MyProject.Import",
    "ItemsPerBatch": 10,
    "SleepBetweenBatches": 500
}

You need to declare your class which inherits from Minion class

 namespace Plugin.MyProject.Import
{
    public class ImportMinion : Minion
    {
        protected IImportMinionMinionPipeline MinionPipeline { get; set; }

        public override void Initialize(IServiceProvider serviceProvider, ILogger logger, MinionPolicy policy, CommerceEnvironment environment, CommerceContext globalContext)
        {
            base.Initialize(serviceProvider, logger, policy, environment, globalContext);
            MinionPipeline = serviceProvider.GetService<IImportMinionMinionPipeline>();
        }

        public override async Task<MinionRunResultsModel> Run()
        {
            this.Logger.LogInformation("ImportMinion running");

            var commerceContext = new CommerceContext(this.Logger, this.MinionContext.TelemetryClient, null);
            commerceContext.Environment = this.Environment;

            CommercePipelineExecutionContextOptions executionContextOptions = new CommercePipelineExecutionContextOptions(commerceContext, null, null, null, null, null);

            MinionRunResultsModel res = await this.MinionPipeline.Run(new MinionRunResultsModel(), executionContextOptions);

            return new MinionRunResultsModel();
        }
    }
}

Because of the changes in the json files you need to bootrastrap your commerce engine.
