aws-codecommit-ci

This automates common code review chores for AWS CodeCommit repositories.

To deploy

#!/bin/bash

set -eufo pipefail

aws configure # Alternatively, set AWS_PROFILE and AWS_DEFAULT_REGION
git clone [email protected]:Amri91/aws-codecommit-ci.git && cd aws-codecommit-ci && ./deploy.sh

To remove

./remove.sh

CodeBuild custom environment variables

  • repositoryName
  • pullRequestId
  • destinationCommit
  • sourceCommit
  • destinationReference
  • sourceReference

Tips

  • If you have too many repositories, the AWS_TRACKED_REPOSITORIES variable will be difficult to maintain. Put the ARNs in a JSON file and use jq -r '. | join(",")' tracked-repositories.json in deploy.sh instead.
  • If your tests require too many things to install, you can use a custom ECR image instead of the standard AWS provided one.
  • If your script becomes too complicated, you can put it in a different repository and reference it in the CodeBuild instead.

Example tests

CFN LINT

Runs cfn-lint.

The target repository must have cfn-lint config file.

echo "Running cfn-lint."
lintResult=0
cfn-lint || lintResult=$?
[ $lintResult -ne 0 ] && echo "cfn-lint check did not pass."
checks+=("$lintResult")

CFN GUARD

Checks all templates against common guard rules.

Templates are in the cf directory and the rules are in a CodeBuild source.

# CFN guard checks
echo "Checking CFN global guard rules"
for template in cf/*.json; do
  guardResult=0
  cfn-guard check --rule_set $CODEBUILD_SRC_DIR/cfn.ruleset --template $template || guardResult=$?
  checks+=("$guardResult")
  [ "$guardResult" -ne 0 ] && echo "Guard check failed for: $template"
done

GIT

Revokes outdated PRs.

echo "Checking rev list."
isOld=$(git rev-list --right-only --count origin/"$sourceBranch"...origin/"$destinationBranch")
checks+=("$isOld")
[ "$isOld" -ne 0 ] && echo "This branch is behind the destination branch, update it."
