# Develop with the Serverless Framework and AWS on a Docker container
Don't you want to download all dependencies on your client? Use a docker container!

You can develop on your client and a *Dockerfile* with all dependencies that you need for your code.

Below you can find the steps for creating your work environment and an example of a *Dockerfile*.

## Usage
Build the docker image
```
cd path/of/the/Dockerfile
docker build . -t my-serverless
```

For Windows
```
cd path\of\your\code
docker run -it --rm -v $HOME\.aws\credentials:/root/.aws/credentials:ro -v $PWD\:/code/ -v /var/run/docker.sock:/var/run/docker.sock -e HOST_PWD="$PWD" my-serverless bash
```

For *nix
```
cd path/of/your/code
docker run -it --rm -v $HOME/.aws/credentials:/root/.aws/credentials:ro -v $PWD/:/code/ -v /var/run/docker.sock:/var/run/docker.sock -e HOST_PWD="$PWD" my-serverless bash 
```
