Travis CI for terraform which uses terraform lint for syntax checking

I have a Terraform template along with two tfvars files. We'd like to source control the Terraform code and want to run terraform lint in Travis-CI before we merge the code.

I'm a beginner in Travis, does anyone have an example of .travis.yml file which I can use in order to download Terraform and run terraform lint to check for syntax errors before merging the pull request?

This will check any files changed between your branch and the target branch.

travis.yml:

sudo: false
cache:
  directories:
  - "${HOME}/bin"
env:
  global:
  - PATH="${HOME}/bin
  - TMPDIR="${TMPDIR:-/tmp}"
  - VERSION="0.11.0"
before_install:
  - if ! terraform version ; then
      mkdir -p "${HOME}/bin"
      pushd "${TMPDIR}" ;
      curl -sSL
        -o terraform.zip
        "https://releases.hashicorp.com/terraform/${VERSION}/terraform_${VERSION}_linux_amd64.zip" ;
      unzip terraform.zip ;
      mv -v terraform "${HOME}/bin/terraform" ;
      chmod +x "${HOME}/bin/terraform" ;
      popd ;
      terraform version ;
    fi
script:
  - test/check-fmt.sh

check_fmt.sh

#!/usr/bin/env bash

if [[ -z "$TRAVIS_PULL_REQUEST_BRANCH" ]]; then
  BRANCH="$TRAVIS_PULL_REQUEST_BRANCH"
else
  BRANCH="master"
fi

exitcode=0
for file in $(git diff --name-only $BRANCH | grep .tf\$); do
  if [[ "$(terraform fmt -write=false "$file" | wc -l)" -gt 0 ]]; then
    echo "ERROR: $file failed to pass terraform fmt"
    exitcode=1
  fi
done
exit $exitcode
