luno-stacks

This repo contains the stacks required to build luno. It also contains our Elasticsearch schema and management actions (within the es directory).

Stacks for luno.

Working with Stacks

To build stacks:

make build

To get stack outputs:

make outputs

To install blueprints:

pip install -e .

To add an encrypted value to the config:

$ aws --region us-east-1 kms encrypt --key-id alias/stacker --plaintext "PASSWORD" --output text --query CiphertextBlob

or simply our shortcut,

$ make encrypt value=<value>

Managing Elasticsearch

We use invoke to manage creating and migrating indices within elasticsearch.

We store the ES endpoint and region within the invoke.yaml file under the correct region. We use this to operate against a specific ES cluster within the tasks, ie:

from invoke import ctask as task


@task
def environment_config(ctx):
    config = ctx[ctx.env]
    print config

We default env to dev. To change this, you can provide an environmental variable: INVOKE_ENV=prod, this will load any production configs.

Run invoke --list to see available commands.
