Simple image, based on Docker, with goss and dgoss added. goss and dgoss can be used with this image to test docker containers. More info can be found on the project github page. This image is based on kiwicom/dgoss, but we have moved the binary downloads into the repo, instead of having it as part of the Dockerfile.

Image Usage

In the directory containing your goss.yaml file (and optionally goss_wait.yaml):

docker run --rm \
    -v $PWD/goss.yaml:/goss.yaml  \
    -v $PWD/goss_wait.yaml:/goss_wait.yaml \
    -v /var/run/docker.sock:/var/run/docker.sock \
    -e GOSS_FILES_STRATEGY=cp \
    praqma/dgoss dgoss run yourImageHere:latest

This image is very useful for building and testing a Dockerfile on CircleCI. Here's an example:

jobs:
  build-and-test:
    docker:
      - image: kiwicom/dgoss
    environment:
      IMAGE_NAME: building-on-ci:ci
      GOSS_FILES_PATH: /wherever/your/goss/files/are/
      GOSS_FILES_STRATEGY: cp
    steps:
      - checkout
      - setup_remote_docker
      - run:
          name: Build Docker image
          command: |
            docker build -t $IMAGE_NAME .
      - run:
          name: Test image with dgoss
          command: dgoss run $IMAGE_NAME

For an example of a production setup, see praqma-training/code-server

Contributing

Any commit on master will automatically update praqma/dgoss:latest, and any new tag pushed to origin will create a named release on Docker Hub. We do not expect this repo to be very active. If you have a suggested contribution, feel free to create a pull request.

Updating goss version

Change the desired GOSS_VERSION and DGOSS_VERSION in update-binaries.sh, and execute the script locally to pull down the new versions. Commit and push.
