# Flod2 - Lightweight Continuous Integration | ||
|
||
Flod2 uses the simplest, most flexible technology to create a CI solution that | ||
uses minimal resources, yet delivers build status as fast as possible. | ||
|
||
|
||
## Design | ||
|
||
Flod consists of two main components. | ||
|
||
The first is the flod binary, and is a queue management tool that triggers hook | ||
scripts when event files appear in a queue, calling the script with a reference | ||
to the event file and managing that file. The flod binary knows nothing about | ||
CI. | ||
|
||
The second component manages a single VM instance. It creates it, then can | ||
install tools and libraries on it, copies a build script to it, and runs that | ||
build script. It waits for a result event to appear, and then shuts down the | ||
VM. | ||
|
||
Everything else is a small script that is launched based on events triggering | ||
hooks, each script having a small and well-defined purpose. | ||
|
||
The combined effect is that a single commit will launch multiple VMs that test | ||
that commit, yielding several results events, which contribute to a status | ||
report. Then the VMs will be shut down and the system returns goes idle, | ||
thereby using minimal resources. | ||
|
||
|
||
## Workflow | ||
|
||
1. A repository commit (task.git) triggers a VCS hook (git on-push) that | ||
composes and queues a commit-event file. This needs to be a very fast | ||
operation. The commit-event file identifies the repository, branch, and a | ||
range of commits. | ||
|
||
2. A commit-event triggers a portability-build script that uses stored | ||
configuration to enumerate supported platforms and composes a build-event | ||
file tailored for each platform. The VM instance component is run, with | ||
the build-event file. | ||
|
||
3. The VM instance component creates a VM, installs software, installs a | ||
build/test/report script, then runs that. It then waits for a result event | ||
file to appear, shuts down the VM and queues the results event. | ||
|
||
4. The result-event triggers a report script that (in an undefined way) | ||
creates a status report of the commit. | ||
|
||
There are other steps/events/scripts, for example, HTML report aggregation, | ||
project overview report creation, performance testing on good builds, result | ||
event archiving, tarball creation and so on. | ||
|
||
|
||
## Data Storage | ||
|
||
There needs to be a hierarchy constituting project/branch/commit/platform, | ||
where result events are stored permanently. | ||
|
||
All events should be archived. Archived events may be purged later. | ||
|
||
|
||
## Configuration | ||
|
||
There needs to be platform-specific configuration, including: | ||
|
||
1. Platform-specific depdendencies, for example the presence of a 'libuuid' | ||
library is necessary on Fedora, but not on OSX. | ||
|
||
2. Project-specific configuration, for example a sequence of commands to run | ||
in order to build and test a project. | ||
|
||
3. Permanent queue details, such as a location, and set of triggered scripts. |
