## Build with Docker
191+
192+
An alternative way to build and run OpenSTA is with
193+
[Docker](https://www.docker.com). After installing Docker, the
194+
following command builds a Docker image.
195+
196+
```
197+
cd OpenSTA
198+
docker build --file Dockerfile.ubuntu_22.04 --tag OpenSTA .
199+
```
200+
201+
To run a docker container using the OpenSTA image, use the -v option
202+
to docker to mount direcories with data to use and -i to run
203+
interactively.
204+
205+
```
206+
docker run -i -v $HOME:/data OpenSTA
207+
```
