Update a Service

Use Duplo to update a Service container from Github Actions

Update the docker image for a service

The goal of this section is to show how you can update the docker image for a service, after you have built that image. This task can be achieved using the duplocloud/actions/update-service action.

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:
  • DUPLO_HOST env var
  • SERVICE_NAME env var
  • TENANT_NAME env var
