## Quick Example for a Ruby Function (4 minutes)
|
|
|
|
This example will show you how to test and deploy a Ruby function to IronFunctions.
|
|
|
|
```sh
|
|
# create your func.yaml file
|
|
fnctl init <YOUR_DOCKERHUB_USERNAME>/hello
|
|
# install dependencies, we need the json gem to run this
|
|
docker run --rm -v "$PWD":/worker -w /worker iron/ruby:dev bundle install --standalone --clean
|
|
# build the function
|
|
fnctl build
|
|
# test it
|
|
cat hello.payload.json | fnctl run
|
|
# push it to Docker Hub for use with IronFunctions
|
|
fnctl push
|
|
# Create a route to this function on IronFunctions
|
|
fnctl routes create myapp /hello
|
|
```
|
|
|
|
Now surf to: http://localhost:8080/r/myapp/hello
|
|
|
|
## Dependencies
|
|
|
|
Create a [Gemfile](http://bundler.io/gemfile.html) file in your function directory, then run:
|
|
|
|
```sh
|
|
docker run --rm -v "$PWD":/worker -w /worker iron/ruby:dev bundle install --standalone --clean
|
|
```
|
|
|
|
Ruby doesn't pick up the gems automatically, so you'll have to add this to the top of your `func.rb` file:
|
|
|
|
```ruby
|
|
require_relative 'bundle/bundler/setup'
|
|
```
|
|
|
|
Open `func.rb` to see it in action.
|
|
|
|
To update dependencies:
|
|
|
|
```sh
|
|
docker run --rm -v "$PWD":/worker -w /worker iron/ruby:dev bundle update
|
|
# then install again to vendor them
|
|
docker run --rm -v "$PWD":/worker -w /worker iron/ruby:dev bundle update
|
|
```
