tarielx/anzer repository overview

⁠Anzer platform and language

Build Status

Both the provided platform and described language implement convenient way for explicit and type-safe composition of cloud functions.

For example the following scheme describes two services and their communication.

package test

type Source = {
    name  :: String
    price :: Float
}
type Prepared = {
    name        :: String
    description :: String
    category    :: Integer
    price       :: Float
}
type Product = {
    id          :: Integer
    name        :: String
    description :: String
    category    :: Integer
    price       :: Float
}
type Error = {
    error :: String
}
github.com/project/prepare[go] :: Source -> Either Prepared Error
github.com/project/save[go] :: Prepared -> Either Product Error
create = prepare >>= save
invoke(create,)

Anzer utility currently supports only Apache OpenWhisk⁠ and Golang⁠.

See the documentation⁠ for details.

⁠As quick as possible start

⁠Setup
  1. Install docker for your system.
  2. Download and install wsk utility from github page⁠.
  3. Find working Apache OpenWhisk instance.
⁠With IBM CloudFunctions
  1. Register at cloud.ibm.com⁠.
  2. Follow the instruction at cloud.ibm.com/openwhisk/learn/cli⁠.
  3. Check the settings with wsk action list. Also ~/.wskprops must contain something like the following.
APIHOST=eu-gb.functions.cloud.ibm.com
NAMESPACE=_
AUTH=short_token
APIGW_ACCESS_TOKEN=big_token
⁠Download Anzer
⁠Binaries

Download suitable binary from realizes page⁠. For example for linux:

sudo curl -L "https://github.com/tariel-x/anzer/releases/download/latest/linux_amd64_anzer" -o /usr/local/bin/anzer
sudo chmod +x /usr/local/bin/anzer
anzer help

For OS X:

sudo curl -L "https://github.com/tariel-x/anzer/releases/download/latest/darwin_amd64_anzer" -o /usr/local/bin/anzer
sudo chmod +x /usr/local/bin/anzer
anzer help
⁠Install from sources
git clone https://github.com/tariel-x/anzer.git
cd anzer
go install
anzer help
⁠Download example project
git clone https://github.com/tariel-x/anzer-example.git
cd anzer-example

Make copy of the envs.yaml.dist and edit according to your CouchDB settings.

cp envs.yaml.dist envs.yaml
nano envs.yaml
anzer build -p wsk -i etl.anz --envs envs.yaml

The output of utility would be name of functions sequence in OpenWhisk.

⁠Create POST API
wsk -i api create /etl post /guest/etl_sequence --response-type json

Make request like the following:

curl -X POST \
  http://your.whisk.com:9001/api/23bc46b1-71f6-4ed5-8c54-816aa4f8c502/etl \
  -H 'Content-Type: application/json' \
  -d '{
    "name": "Opel",
    "model": "Astra;J",
    "phone": "79095544445",
    "price": 500.50,
    "photos": [
    	"http://origin.org/path/image.jpeg"	
    ],
    "year": 2014
}'

The expected result is:

{
    "car": {
        "brand": "Opel",
        "model": "Astra"
    },
    "err": null,
    "id": 38081
}

⁠Detailed quick start

Detailed quick start.⁠

⁠Roadmap

  1. Full support of OR-types and pattern-matching in the scheme.
  2. Remake subsystem for building functions.
