Updating Conan Packages with Wercker

I’ve recently invested lot of time in transitioning to Wercker for my CI needs. So far, I’m reasonably impressed.

One task I wanted was to automate was uploading an updated Conan package to conan.io on a successful wercker build. I’m not using the binary package functionality of Conan, just the dependency tracking.

Here’s the wercker.yml from g2o_conan showing what I do.

box: amarburg/lsdslam-dev-host:conan-latest

build:
  steps:

    - script:
      name: Debug test
      code: |
           rake debug:test
           rake debug:clean

    - script:
      name: Upload to conan.io
      code: |
        conan user -p "$CONAN_PASSWORD" $CONAN_USERNAME
        conan export amarburg/testing
        conan upload "g2o*" --confirm

The second script step uses the conan command line to authenticate a user (set with the Wercker env. variables $CONAN_USERNAME and $CONAN_PASSWORD), export the package to the local conan store, and then push it to conan.io.

Note that your wercker box / Docker image needs to have conan installed. The ‘with-conan’ branch of my LSD-SLAM dev box has it baked in. The resulting image is amarburg/lsdslam-dev-host:conan-latest.
