gh-ost-ci-env

CI environment for gh-ost testing.

This repository serves as a collateral repo to gh-ost, GitHub's schema migration tool. It provides a multi-version testing environment that can be used by gh-ost's CI, without polluting gh-ost's repo.

Since gh-ost uses public Travis CI, we confine ourselves to a single docker image, created at each CI. To that effect we wish to be able to quickly bootstrap multiple MySQL master-replica environments.

We choose dbdeployer, a tool that deploys MySQL replication clusters in user space, created by @datacharmer.

This repository incorporates:

• dbdeployer binary
• Various MySQL minimal tarballs, available via https://github.com/datacharmer/mysql-docker-minimal by @datacharmer.

Usage

gh-ost CI will use this repo as follows:

• Clone it from within the Docker image
• Deploy and bootstrap MySQL master-replica environments
• Run gh-ost integration tests on each master-replica environment
