Regula + Travis CI

We're gonna get Regula up and running, with something I thought of which is using a mock_key.json file I created, this is so you can sample it first, once you get a final main.tf (Terraform), you can edit as you please. Once Terraform calls Regula then Travis picks up the /POST and sees if it gets a response from Regula. This is a working example, and Travis is in my opinion the easiest development tool, to set Regula up on and get up and running with max uptime.

Terraform

We can grab Terraform by putting this in our script hook in our travis.yml file:

curl -fsSL https://apt.releases.hashicorp.com/gpg | sudo apt-key add -
sudo apt-add-repository "deb [arch=amd64] https://apt.releases.hashicorp.com $(lsb_release -cs) main"
sudo apt-get update && sudo apt-get install terraform

Kubernetes

There is a compliant Kubernetes pod in this repo I've also banged out, since we're using Travis there's not alot of need for it, but I'm just trying to give you the most feasible option.

Swagger

There's a full swagger.yaml file within the repository.

Travis CI

All of the .travis.yml file was made by me (Montana Mendy). Just some crucial points to go over for the .travis.yml:

branches:
  only:
    - master
    - /^(cherry-pick-)?backport-\d+-to-/
addons:
  apt:
    packages:
      - moreutils
env:
  global:
    - 'PATH="$HOME/.local/bin:$PATH"'
    - REGULA_VERSION=1.6.0
install:
  - >-
    if [[ "${TRAVIS_COMMIT_MESSAGE}" = *"[Build latest]"* ]]; then export
    BUILD_VERSION="$(cat packaging/version | cut -d'-' -f1,2 | sed -e
    's/-/./g').latest"; fi;
before_script:
  - mkdir "$HOME/.local/bin"
  - >-
    curl -L
    "https://github.com/fugue/regula/releases/download/v${REGULA_VERSION}/regula_${REGULA_VERSION}_Linux_x86_64.tar.gz"
    | tar -xvz -C "$HOME/.local/bin"
  - 'RANGE1=`echo "$TRAVIS_COMMIT_RANGE" | awk ''{n=split($1,a,".");print a[1]}''`'
script:
  - REGULA_OUTPUT="$(mktemp)"
  - (regula run -f json || true) | tee "$REGULA_OUTPUT"
  - REGULA_RULES_PASSED="$(jq -r '.summary.rule_results.PASS' "$REGULA_OUTPUT")"
  - REGULA_RULES_FAILED="$(jq -r '.summary.rule_results.FAIL' "$REGULA_OUTPUT")"
  - regula -v
  - regula init
  - regula run
  - regula run --format table
  - >-
    echo "${REGULA_RULES_PASSED} rules passed, ${REGULA_RULES_FAILED} rules
    failed" >&2
  - 'if [[ "$REGULA_RULES_FAILED" -gt 0 ]]; then exit 1; fi'
after_deploy:
  - >-
    if [ -n "${BUILDER_NAME}" ]; then rm -rf /home/${BUILDER_NAME}/* && echo
    "Cleared /home/${BUILDER_NAME} directory" || echo "Failed to clean
    /home/${BUILDER_NAME} directory"; fi;
  - 'if [ -d "${PACKAGES_DIRECTORY}" ]; then rm -rf "${PACKAGES_DIRECTORY}"; fi;'
  - >-
    if: "((branch IN (master, develop) && type = push) OR branch =~ /.*env.*/ OR
    commit_message =~ /\\[recreate env\\]/) AND commit_message !~ /\\[delete
    env\\]/ AND type != cron AND commit_message !~ /\\[execute .*. test\\]/ AND
    commit_message !~ /\\[start recreate scheduler\\]/"
  - >-
  - regula run mock_key.json

We are going to change the PATH and use cURL to fetch the latest version of Regula, make sure you have it by going to https://regula.dev/. You can also make sure by running:

regula version

In the CLI, but it will print out something like this:

If the regula command isn't working you need to install Regula and the binary. Make sure you run the following:

brew tap fugue/regula

Once brew has symlinked fugue/regula, you can now start the install process:

brew install regula

If you want to upgrade regula, just run:

brew upgrade regula

Usage

The usage does get pretty complex from the Regula side - I've been thinking about writing a bash script to help users and make it easier, if you think this is a good idea and want to see it just email me at montana@linux.com, and or need any help in the mean time.
