Update a service

Use Duplo to update a service's 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.
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
name: Build and Deploy
on:
  # (Optional) Allows users to trigger the workflow manually from the GitHub UI
  workflow_dispatch:
​
  # Triggers the workflow on push to matching branches
  push:
    branches:
      - master
env:
  duplo_host: https://mysystem.duplocloud.net  # CHANGE ME!
  duplo_token: "${{ secrets.DUPLO_TOKEN }}"
  SERVICE_NAME: myservice                      # CHANGE ME!
  TENANT_NAME: mytenant                        # CHANGE ME!
​
# A workflow run is made up of one or more jobs that can run sequentially or in parallel
jobs:
  build:
    # YOU SHOULD ALREADY HAVE THIS FROM THE PREVIOUS DOCUMENTATION SECTION
    # ...
    # ...
  deploy:
    runs-on: ubuntu-latest
    needs:
      - build
    steps:
      - name: Checkout
        uses: actions/[email protected]
      
      # Update the backend service to use the new image.
      - name: Deploy
        uses: duplocloud/ghactions-service-[email protected]
        with:
          tenant: "${{ env.TENANT_NAME }}"
          services: |-
            [
              { "Name": "${{ env.SERVICE_NAME }}", "Image": "${{ needs.build.outputs.image }}" }
            ]
