This is wercker build step script to package your directories as .zip.

In the wercker.yml of your application use the following step definition:

steps:
   - tcnksm/zip:
     input: $WERCKER_OUTPUT_DIR/pkg
     output: $WERCKER_OUTPUT_DIR/dist

You must set input directory where directories you want to package are in and output directory where zip archeives will be generated. Both must be set as absolte path ($WERCKER_OUTPUT_PATH is built-in environmental valiable which is used for pass the artifacts between build step and deploy step).

If you use wercker-box which is not installed zip, you need additional step:

steps:
    - script:
      name: install zip
      code: |
        sudo apt-get update -y
        sudo apt-get upgrade -y
        sudo apt-get install -y zip
    - tcnksm/zip
        input: "pkg"
        output: "dist"
