An attempt to centralize the configuration and building of application environments at eLife, locally (Vagrant) and remotely (AWS).

Download:

git clone ssh://[email protected]/elifesciences/builder

Install:

./update.sh

Fix any missing pre-requisites and call ./update.sh again until you see the happy

all done

message. Updating in the future is as simple as:

git pull
./update.sh

If you are outside of the eLife organization, make sure the write-context-to-s3 and write-keypairs-to-s3 keys in settings.yml keys are `False. Their use is not supported.

Your settings.yaml file was created automatically and contains options for tweaking the behaviour of builder, like the project file it should be using.

By default it points to the ./projects/elife.yaml project file. This file describes all eLife projects that can be built and their environments. See here for more project file documentation.

Project files and the settings.yml file are the only two places where configuration is supported.

'configuration' also exists in ./src/buildercore/config.py if you're a builder dev.

After successfully installing and configuring builder, launching a Vagrant instance is a good test that all is working correctly.

The Vagrantfile can build any project, you just need to tell it which one:

$ vagrant up
You must select a project:

1 - journal--vagrant
2 - api-gateway--vagrant
3 - ...
>

... or it can be done with environment variables:

$ PROJECT=journal vagrant up

The other half of the builder project is the ability to create and manage AWS resources. This is controlled with the "bldr" script:

$ ./bldr -l

Will list all builder tasks found in src/. These tasks are just Python functions.

A master-server instance must exist before project instances can be brought up. See here for a walkthrough.

To launch a project backed by a code repository to AWS:

$ ./bldr deploy
// or specify project and environment
$ ./bldr deploy:journal,prod

To launch a instance of any project to AWS, use:

// or specify project and environment
$ ./bldr launch:api-gateway,prod

To ssh into one of these machines:

$ ./bldr ssh:journal--prod

General:

• project files

AWS:

• feature: write keypairs to S3
• creating a master server
• caveats

Development

• adding projects
• technology
• salt
• testing
