Deploying a multi-instance pipeline

How to deploy a multi-instance pipeline?

1. Create the multi-instance model

Before you create the instances, you need to create a multi-instance model. To do this, go to the Multi-Instance page, click Create, and define a name, description, and the fields of the instances, that is, the variables that should receive values in each environment.

Take a look at the following example:

Once this is done, click Confirm to create the model.

2. Configure the instances

Now, you can create the instances that will match the model you created in the last step. To do this, find the model in the list and click on the corresponding Configure action button. This way you can create the instances of this model one by one, entering and setting values for each field.

In the following example, "instance1" and "instance2" are two stores that receive the values of each variable that can be configured for both test and prod. This is repeated for all other instances to be created.

After entering the variables, just click Save.

3. Create a multi-instance pipeline

In this step, we create a pipeline and define it as a multi-instance. To do this, access the settings by clicking on the Settings button and activate the Is it a multi-instance? option:

After selecting the Is it multi-instance? option, specify which multi-instance model the pipeline will report to. In our example, we are using the "multi-instance-model".

Since this is an event, we need to inform the trigger an instance variable that will be executed using the pattern -{{replica.instance_variable_name}}., as in the example below:

Running queries in Execution panel

If you are running an execution in a multi-instance pipeline, you can select the instance you want to run in the Test tab, as in the following example:

In this way, it is possible to consult the values previously configured in the selected instance via the pattern {{replica.instance_variable_name}}.

4. Deploying a multi-instance pipeline

Now that you have configured the template and set the pipeline to multi-instance, you need to edit the pipeline request with the instance on which you want to deploy it. This way, the instance name will be added to the pipeline name after deployment.

For example: once the "multi-instance-pipeline" is deployed on "instance1", its name on the Run pipeline card will be "multi-instance-pipeline-instance1".

In the following example, the "multi-instance-pipeline" is deployed on "instance1" and "instance2".

After editing, simply click Deploy.

Below is the “multi-instance-pipeline” already deployed on "instance1" and "instance2" instances in the Run phase shown in the pipeline card:
