thrift-god
A god repository for all your thrifts
Introduction
thrift-god
provides a "package manager" for thrift interfaces.
It comes with two CLI commands, thrift-god
and thrift-get
.
Motivation
- The source of truth for a service should live with the service. You want the thrift definition to be checked into the repository
- Every service needs a copy of the thrift definition for any service That it wants to talk too. This definition should be static. You do not want it to change at run-time.
- There should only be one version of the world. Your company runs at a single version in production; all the files should ultimately be under one version.
- The one version should be live. Developers should not manually publish
new versions; instead we should just take
master
as the source of truth.
thrift-get
As a client: As a developer I want to be able to talk to other services; To do this I need to find their Thrift interface definitions.
I can run thrift-get list
to show all available services
and their IDL files.
If I want to download one of these files I can
thrift-get fetch {service}
and it will fetch the IDL file into
./thrift/{service}.thrift
.
Once you fetch your first service we also write the
./thrift/meta.json
meta file that contains the version of
the file as well as the time it was last changed.
All thrift files are under one version; If you want to update
to the latest version just run thrift-get update
and it will
update all thrift files to the latest version as well as updating
the ./thrift/meta.json
.
Since the thrift definitions define the interfaces of the services in production, there is only one version for all files. When you update anything, you update everything to the current version.
As a server:
If your developing the backend for a new service you just have
to commit the thrift definition into git; by convention we place
it in ./thrift/service.thrift
.
The thrift-god
daemon will fetch it and put it in the repository.
thrift-god
As an adminstrator: To set up the thrift interface repository you can run the
thrift-god
deamon. You just run thrift-god --config-file={path}
and it will populate the thrift remote repository.
The config file contains the following fields
The thrift-god
daemon will fetch all the remotes and place their thrift
files in the upstream
repository. You can use thrift-get
to fetch from
the upstream repository.
TODO:
This project is not done yet:
- Implement
thrift-god
config loader - Implement fetching from
remotes
intoupstream
- Make
thrift-god
a repeating cron job - Support
localFileName
in config. - Support
branch
in config. - Implement
thrift-get
binary.
Installation
npm install thrift-god --global
