image.inside leaks volumes

XMLWordPrintable

      When using docker.inside(){....} jenkins does not clean up volume mounts. This fills the filesystem and can lead to failure of future builds due to space and/or handle exhaustion.

      Output from a jenkins job shows that the 'docker rm' command is missing the '-v' to clean up created volumes.

      pipeline:

          docker.image('imagename').inside {
      stage('NPM Install') {
          withEnv(["NPM_CONFIG_LOGLEVEL=warn"]) {
              sh 'npm install'
          }
        ... more stages...
      }

      output (shortened)
