# Go examples
|
|
|
|
The `go` runtime uses the [`plugin` package](https://golang.org/pkg/plugin/) to dynamically load an HTTP handler.
|
|
|
|
## Requirements
|
|
|
|
First, [set up your fission deployment with the go environment](https://github.com/fission/fission/blob/master/environments/go/README.md).
|
|
|
|
To use this environment, download the [build helper
|
|
script](https://raw.githubusercontent.com/fission/fission/master/environments/go/builder/go-function-build).
|
|
|
|
The script must be run in the same directory as the function you're
|
|
building.
|
|
|
|
## Examples
|
|
|
|
### hello.go
|
|
|
|
`hello.go` is an very basic HTTP handler returning `"Hello, World!"`.
|
|
|
|
```
|
|
# Build the function as a plugin. Outputs result to 'function.so'.
|
|
$ go-function-build hello.go
|
|
|
|
# Upload the function to fission
|
|
$ fission function create --name hello --env go-runtime --package function.so
|
|
|
|
# Map /hello to the hello function
|
|
$ fission route create --method GET --url /hello --function hello
|
|
|
|
# Run the function
|
|
$ curl http://$FISSION_ROUTER/hello
|
|
Hello, World!
|
|
```
