The easiest way to run local aftok infrastructure is using Docker and
docker-compose. Several steps are necessary to set up your local environment
for development.
Obtaining Docker Images
-----------------------
The docker-compose setup requires 4 images:
* `aftok/aftok-server:latest`
* `nginx/nginx:latest`
* `postgres/postgres:9.4`
* `electriccoinco/zcashd:v4.0.0`
You can obtain these images by running the following. This assumes the use of
`sudo` under Linux; this may not be necessary on other platforms (e.g. OSX).
~~~bash
make build-image # build the aftok-server image(s)
docker pull nginx/nginx:lates
docker pull postgres/postgres:9.4
docker pull electriccoinco/zcashd:v4.0.0
~~~
If you have problems building the aftok-server image, you can also obtain
a prebuilt image by running
~~~bash
docker pull aftok/aftok-server:latest
~~~
Configuration Files
-------------------
A number of configuration files are required for docker-compose to be able
to run all of the necessary containers successfully. You should create
a `local` directory, which will have the following contents:
~~~
local
├── conf
│   ├── nginx
│   │   ├── mime.types
│   │   └── nginx.conf
│   ├── nginx-certs
│   │   ├── aftok.crt
│   │   └── aftok.key
│   ├── server
│   │   ├── aftok.bip70-chain.cert.pem
│   │   ├── aftok.bip70.key.pem
│   │   ├── aftok.cfg
│   │   ├── aftok-migrations.cfg
│   │   └── snap-site-key
│   └── zcashd
│       ├── zcash-data
│       │   └── zcash.conf
│       └── zcash-params
└── db-dumps
    └── aftok.sample.plsql
~~~
Sample default versions of each of these files can be found in the `conf`
directory; you can simply use the following to set up your local environment:

~~~bash
mkdir local
cp -r conf local
# The aftok-zcashd container runs zcashd as user 2001, so we change the
# owner of the zcashd configuration directories to this user.
sudo chown -R 2001.2001 local/conf/zcashd
~~~
Database Initialization
-----------------------

RUN apt-get install -y --no-install-recommends pkg-config

  host = "127.0.0.1"

  host = "aftok-db"

smtpUser = "whoareyou"
smtpPass = "iami"

smtpUser = "your_sendgrid_username"
smtpKey  = "your_sendgrid_key"

  # Signing key for BIP-70 payment requests

recaptchaSecret = "your_secret_goes_here"
zcashd {
  zcashdHost = "aftok-zcashd"
  zcashdPort = 8232
}
