Deploy Application
Deploy an application to Kubernetes.
To use this step, the application should already be deployed in the Kubernetes cluster. This step will re-deploy your existing service.
Parameter | Description | Required |
title | The display name of the step. | No |
type | The type of the Microtica built-in step. Should always be deploy for this type of step. | Yes |
target | Should always be kubernetes for this type of step. | Yes |
cluster | The name of the existing Kubernetes cluster. | Yes |
namespace | Deploy the application in a specific namespace. Default: microtica | No |
service | The name of the existing application to be deployed. | Yes |
tag | Docker image tag to be applied with the deployment. Default: latest | No |
branch_filter | If specified, deployment will be executed only if the pipeline was triggered by push on the matched branch. Otherwise, deployment will be triggered on every pipeline execution. | No |
We assume that application with name my-app is already being deployed in the Kubernetes cluster with name my-cluster. You can read more about how to create and deploy applications here.
In the following example we deploy a application on Kubernetes with an image tag that’s previously been built and pushed to a remote Docker registry.
To dynamically deploy the image that’s just been built, we use MIC_PIPELINE_EXECUTION_ID as a reference value while pushing the image on a remote Docker registry and use the same value when deploying the application.
To trigger a deploy only if the pipeline was triggered by push on a specific branch, we can use the branch_filter parameter to achieve that.
Basically, if you specify develop as a value, the deployment will be triggered only if push was made on the develop branch.
If branch_filter is not specified, deploy will be triggered on each pipeline execution.
