FutoIn Continuous Integration & Delivery Tool

Intro

There are many continuous integration & delivery tools, but they are primarily targeted at own infrastructure. The demand for a new meta-tool is to merge many operations of different technologies like npm, composer, bundler, nvm, rvm, php-build and others under a single tool for runtime setup, project development, build, deployment and running.

NOTE: current focus is on web projects, but other types are supported as well.

Full theoretical details are defined as FutoIn Spec FTN16 available at: https://github.com/futoin/specs/blob/master/draft/ftn16_cid_tool.md

Features

• Single tool for development, testing and production

• Intelligent automation of human-like behavior

• Automatic detection & setup of all tool dependencies

• Resource limit auto-detection & distribution

• Rolling deployments for zero downtime

• Container-friendly

• Technology-neutral

• Easily extendable & portable

• Fine tune of all aspects

• nexus - only v2 as v3 lacks complete REST API yet.

  • Always tested in standard cycle.

• scp - SSH-based secure copy.

  • Always tested in standard cycle.

• svn - Subversion is quite suitable for Production release builds, but please avoid using it for snapshots.

  • Always tested in standard cycle.

• twine - Upload only to Python Package Index.

  • Promotion between repos is not supported.

• Not implemented, but planned:

  • Nexus v3 - after sane REST API is implemented.

• Other Linux

  • it should work without issues, if system packages are installed manually.

Setup

cid is written in commonly available Python language supporting both Python versions 2.7 and 3+.

Run the following:

pip install futoin-cid

If pip is not available then it’s strongly suggested to install one first:

easy_install pip

For best user experience, it’s suggested to allow system package installation (only) through sudo without password. It should minimize impact on security.

A convenient OS-agnostic way is to do it this way:

cid sudoers | sudo tee -a /etc/sudoers

One obvious drawback is management of package trusted signing keys. It can be disabled. Then please run the following command instead:

cid sudoers --skip-key-management | sudo tee -a /etc/sudoers

Typical use cases

1. Prepare project for development:

   cid prepare master --vcsRepo=git:user@host:git/repo.git
   # create VCS working copy with specified VCS ref
   # auto-detects tools and executes:
   #  npm install, composer install, bundle install, etc.

2. Prepare project for release:

   cid tag master
   # updates auto-detected files like package.json
   # creates tags
   # "patch" version increment is the default behavior

3. Release builds on CI server:

   cid ci_build v1.0.0 Releases --vcsRepo=git:user@host:git/repo.git \
       --rmsRepo=svn:user@host/rms

4. Nightly builds on CI server:

   cid ci_build master Nightly --vcsRepo=git:user@host:git/repo.git \
       --rmsRepo=scp:user@host

5. Production-like execution environment in development:

   cid devserve
   # PHP-FPM, Ruby rack, Python WSGI, nginx... Doesn't matter - it knows how!

6. Staging deployment from VCS:

   cid deploy vcsref master --vcsRepo=git:user@host:git/repo.git \
       --deployDir=/www/staging \
       --limit-memory=1G
   # resource limits are preserved across runs, if not overridden

7. Production deployment from RMS:

   cid deploy rms Releases --rmsRepo=svn:user@host/rms \
       --deployDir=/www/prod \
       --limit-memory=8G \
       --limit-cpus=4
   # resource limits are preserved across runs, if not overridden

8. Alter resource limits before or after deployment:

   cid deploy setup
       --deployDir=/www/prod \
       --limit-memory=16G

9. Execution of deployed project:

   cid service master --deployDir=/www/prod

10. Use any supported tool without caring for setup & dependencies:

    cid tool exec dockercompose -- ...
    # ensures:
    # * setup of system Docker
    # * setup of virtualenv
    # * setup of pip
    # * setup of docker-compoer via pip into virtualenv
    # actually, executes

Usage

Please see details in the FTN16 spec:

cid init [<project_name>] [--vcsRepo=<vcs_repo>]
    [--rmsRepo=<rms_repo>] [--permissive]
    Initialize futoin.json with automatically detected data.

    If <project_name> is omitted and not known from
    auto-detection then basename of containing folder is used.

cid tag <branch> [<next_version>] [--vcsRepo=<vcs_repo>] [--wcDir=<wc_dir>]
    Get the latest <branch>.
    Update source for release & commit.
    Create tag.

    Version must be in SEMVER x.y.z. format: http://semver.org/

    If <next_version> is omitted, the PATCH version part is incremented.

    If <next_version> is one of 'patch', 'minor' or 'major then
    the specified version part is incremented and all smaller parts are
    set to zero.

    Current version is determined by tools (e.g. from package.json)

cid prepare [<vcs_ref>] [--vcsRepo=<vcs_repo>] [--wcDir=<wc_dir>]
    Retrieved the specific <vcs_ref>, if provided.
    --vcsRepo is required, if not in VCS working copy.
    Action depends on detected tools:
    * should clean up the project
    * should retrieve external dependencies

cid build [--debug]
    Action depends on detected tools.
    Runs tool-specific build/compilation.

cid package
    Action depends on detected tools.
    Runs tool-specific package.
    If package is not found then config.package folder is put into archive -
        by default it's '.' relative to project root.

cid check [--permissive]
    Action depends on detected tools.
    Runs tool-specific test/validation.

cid promote <rms_pool> <packages>... [--rmsRepo=<rms_repo>]
    Promote package to Release Management System (RMS) or manage
    package across RMS pools.

Development

Current goal is to get a feature-complete tool. There is a strong concept, but some parts of code became messy. Refactoring is postponed after feature stabilization.

Notes for contributing:

1. ./bin/cid run autopep8 - for code auto-formatting

2. ./bin/cid check - for static analysis

3. ./tests/run_vagrant_all.sh [optional filters] - to make sure nothing is broken
