How to optimize Bitbucket pipeline for Sonarcloud scan pipe?

Question

Every time Sonarcloud scanner starts, it download the image. It slowing down whole pipeline and generate additional cost.

Poor documentation don't have any information about additional cache https://bitbucket.org/sonarsource/sonarcloud-scan/src/master/

Answer 1

Try to use cache for docker (Docker is used internally in sonarcloud-scan pipe).

After enabling cache it runs faster by 1 minute

    - step: &sca
          image: atlassian/default-image:2  #quickest image
          name: SonarCube SCA
          caches:
            - docker
          script:
            - pipe: sonarsource/sonarcloud-scan:1.1.0
            - pipe: sonarsource/sonarcloud-quality-gate:0.1.3
          services:
            - docker
