Make sure you have Docker installed on your machine: [macOS](https://docs.docker.com/docker-for-mac/install/), [Windows](https://docs.docker.com/docker-for-windows/install/) or [Linux](https://docs.docker.com/install/linux/docker-ce/ubuntu/).
Build the Docker image:
Build *iwasm* with the Docker image:
``` Bash
docker build --rm -f "Dockerfile" -t wamr:latest .
$ cd ci
$ ./build_wamr.sh
$ ls ../build_out/
```
Run the image in interactive mode:
``` Bash
docker run --rm -it wamr:latest
