Clarification on how image tag is generated for Git deployments

Indeed, we don’t use the git commit ID to tag the image but an internal Qovery ID. You can find the detailed code here.

Qovery/engine/blob/main/src/build_platform/local_docker.rs#L162


      
          let image_to_build = ContainerImage::new(
              build.image.registry_url.clone(),
              build.image.name(),
              vec![build.image.tag.clone(), "latest".to_string()],
          );
          
          let image_cache =
              ContainerImage::new(build.image.registry_url.clone(), build.image.name(), vec!["latest".to_string()]);
          
          // Check if the image does not exist already remotely, if yes, we skip the build
          let image_name = image_to_build.image_name();
          logger.send_progress(format!("🕵️ Checking if image already exists remotely {image_name}"));
          if let Ok(true) = self.context.docker.does_image_exist_remotely(&image_to_build) {
              logger.send_progress(format!("🎯 Skipping build. Image already exists in the registry {image_name}"));
              build_record.stop(StepStatus::Skip);
              // skip build
              return Ok(());
          }
          
          logger.send_progress(format!("⛏️ Building image. It does not exist remotely {image_name}"));

image_to_build.image_name() details is here.

                  let host = self.host_with_port();
                  match &self.id {
                      ImageId::Digest(digest) => vec![format!("{}/{}@{}", host, &self.name, digest)],
                      ImageId::Tags(tags) => tags
                          .iter()
                          .map(|tag| format!("{}/{}:{}", host, &self.name, tag))
                          .collect(),
                  }
              }
          
              pub fn image_name(&self) -> String {
                  self.image_names().remove(0)
              }
          
              pub fn repository_with_host(&self) -> String {
                  format!("{}/{}", self.host_with_port(), self.name)
              }
          }
          
          #[derive(Debug, Clone)]
          enum BuilderLocation {

If you explain to me what you need, I’ll try to guide you in a more precise way.
