ci-cache

Cache files and folders between continues integration builds for faster build execution. Usable with Travis CI and others.

Usage

Configuration

The ci-cache uses environment variables to receive the AWS config.

CI_CACHE_S3_BUCKET="cache-bucket"
CI_CACHE_S3_PREFIX="prefix-for-files/"
CI_CACHE_S3_KEY="aws-key"
CI_CACHE_S3_SECRET="aws-secret"

Download cached file / folder

ci-cache get --name cache-key --output-path .

Upload cached file / folder

ci-cache set --name cache-key --content cache-folder --hash-file version.lock

The cached is only re-uploaded, if the hash-file has changed.

Examples (Travis CI)

You should encrypt your AWS credentials

travis encrypt CI_CACHE_S3_KEY=AWS_KEY CI_CACHE_S3_SECRET=AWS_SECRET --add
