Conform

Policy enforcement for your pipelines.

Conform is a tool for enforcing policies on your build pipelines.

Some of the policies included are:

• Commits: Enforce commit policies including:
  • Commit message header length
  • Developer Certificate of Origin
  • GPG signature
  • Conventional Commits
  • Imperative mood
  • Spell check
  • Maximum of one commit ahead of master
  • Require a commit body
  • Jira issue check
• License Headers: Enforce license headers on source code files.

Getting Started

To install conform you can download a release, or build it locally (go must be installed):

go get github.com/talos-systems/conform

Now, create a file named .conform.yaml with the following contents:

policies:
  - type: commit
    spec:
      header:
        length: 89
        imperative: true
        case: lower
        invalidLastCharacters: .
        jira:
          keys:
          - PROJ
          - JIRA
      body:
        required: true
      dco: true
      gpg: false
      spellcheck:
        locale: US
      maximumOfOneCommit: true
      conventional:
        types:
          - "type"
        scopes:
          - "scope"
        descriptionLength: 72
  - type: license
    spec:
      skipPaths:
        - .git/
        - .build*/
      includeSuffixes:
        - .ext
      excludeSuffixes:
        - .exclude-ext-prefix.ext
      header: |
        This is the contents of a license header.

In the same directory, run:

$ conform enforce
POLICY         CHECK                        STATUS        MESSAGE
commit         Header Length                PASS          <none>
commit         Imperative Mood              PASS          <none>
commit         Header Case                  PASS          <none>
commit         Header Last Character        PASS          <none>
commit         DCO                          PASS          <none>
commit         Conventional Commit          PASS          <none>
commit         Number of Commits            PASS          <none>
commit         Commit Body                  PASS          <none>
license        File Header                  PASS          <none>

To setup a commit-msg hook:

cat <<EOF | tee .git/hooks/commit-msg
#!/bin/sh

conform enforce --commit-msg-file \$1
EOF
chmod +x .git/hooks/commit-msg

We also provide a Pre-Commit hook that you can use as follows:

# .pre-commit-config.yaml
repos:
  - repo: https://github.com/talos-systems/conform
    rev: master
    hooks:
      - id: conform
        stages:
          - commit-msg
