.travis.yml

# We are using docker, so we need sudo.
# We need docker service to be pre-installed as soon as we try to run our 
# build because we need Travis to run our builds and test container after that.
sudo: required
services:
  - docker

# 1st env gets the SHA of a commit to be used inside deploy.sh
# 2nd env tells the Google Cloud SDK to not display any prompts that require user input
env:
  global:
    - GIT_SHA=$(git rev-parse HEAD)
    - CLOUDSDK_CORE_DISABLE_PROMPTS=1

# Commands run before the tests
# 1. Unencrypt service-account.json file
# 2. Download and install Google Cloud SDK
# 3. Look at the default install directory and source the file
# 4. Install kubectl inside our Travis env
# 5. Authorize gcloud to execute stuff (Service Account is similar to AIM used in AWS) 
# 6. Set project on GCP
# 7. Set the zone of the project
# 8. Tell to reach cluster and work with our cluster "multi-cluster"
# 9. Log in to the docker hub. The echo command sends the value of env variable and then
#    essentially emit that over stdin as input to the next command (after pipe)

# Using Travis, we need to make sure the tests exit after running and don't cause our builds to fail.

# Travis does not have a built-in script to run for K8S, so we need to do it through script
