This example pulls the build context from a GCS bucket.
To use a local directory build context, you could consider using configMaps to mount in small build contexts.

### Running kaniko in gVisor

Running kaniko in [gVisor](https://github.com/google/gvisor) provides an additional security boundary.
You will need to add the `--force` flag to run kaniko in gVisor, since currently there isn't a way to determine whether or not a container is running in gVisor.

```shell
docker run --runtime=runsc -v $(pwd):/workspace -v ~/.config:/root/.config \
gcr.io/kaniko-project/executor:latest \
--dockerfile=<path to Dockerfile> --context=/workspace \
--destination=gcr.io/my-repo/my-image --force
```

We pass in `--runtime=runsc` to use gVisor.
This example mounts the current directory to `/workspace` for the build context and the `~/.config` directory for GCR credentials.
