Update Service

Introduction

The goal of this section is to show how you can update the docker image for a service, after you have built that image.

Example Workflow

This example makes some assumptions:

Your workflow already has a build job - we created one in the previous section
Your build job declares an output named image - also done in the previous section

To use it you will need to change:

DOCKER_REPO
DOCKER_IMAGE_NAME
DUPLO_SERVICE_NAME
DOCKER_REPO
ECR_REGION
