Custom Pod Scheduling

Is it possible to set a custom node affinity for services that run in Qovery via node affinities or topology spreads? looking to make sure my replicas are spread across AZs.

Hi @Marcelo_Labardini , I think you might be interested in looking at this part since Qovery Engine (in charge of deploying your apps) is fully open-source.

              projectLongId: {{ project_long_id }}
              qovery.com/service-id: {{ long_id }}
              qovery.com/service-type: application
              qovery.com/environment-id: {{ environment_long_id }}
            annotations:
              checksum/config: {% raw %}{{ include (print $.Template.BasePath "/secret.yaml") . | sha256sum }}{% endraw %}
              checksum/config-mount-files: {% raw %}{{ include (print $.Template.BasePath "/mounted_files_secret.yaml") . | sha256sum }}{% endraw %}
              appCommitId: {{ version }}
          spec:

                    podAffinityTerm:
                      labelSelector:
                        matchExpressions:
                          - key: "appLongId"
                            operator: In
                            values:
                            - {{ long_id }}

Does it respond to your question?
