# Packaging your Function
|
|
|
|
Packaging a function has two parts:
|
|
|
|
* Create a Docker image for your function with an ENTRYPOINT
|
|
* Push your Docker image to a registry (Docker Hub by default)
|
|
|
|
Once it's pushed to a registry, you can use it by referencing it when adding a route.
|
|
|
|
## Using fn
|
|
|
|
This is the easiest way to build, package and deploy your functions.
|
|
|
|
|

### Creating an image
|
|
|
|
The basic Dockerfile for most languages is along these lines:
|
|
|
|
```
|
|
# Choose base image
|
|
FROM iron/go
|
|
# Set the working directory
|
|
WORKDIR /function
|
|
# Add your binary or code to the working directory
|
|
ADD funcbin /function/
|
|
# Set what will run when a container is started for this image
|
|
ENTRYPOINT ["./funcbin"]
|
|
```
|
|
|
|
Then you simply build your function:
|
|
|
|
```sh
|
|
docker run --rm -v "$PWD":/go/src/$FUNCPKG -w /go/src/$FUNCPKG iron/go:dev go build -o funcbin
|
|
docker build -t $USERNAME/myfunction .
|
|
```
|
|
|
|
Or using [fn](../fn/README.md):
|
|
|
|
```sh
|
|
fn build
|
|
```
|
|
|
|
### Push your image
|
|
|
|
This part is simple:
|
|
|
|
```sh
|
|
docker push $USERNAME/myfunction
|
|
```
|
|
|
|
Or using [fn](../fn/README.md):
|
|
|
|
```sh
|
|
fn push
|
|
```
