# How to use this image.
**Note:** as of [docker-library/tomcat#181](https://github.com/docker-library/tomcat/pull/181), the upstream-provided (example) webapps are *not* enabled by default, per [upstream's security recommendations](https://tomcat.apache.org/tomcat-9.0-doc/security-howto.html#Default_web_applications), but are still available under the `webapps.dist` folder within the image to make them easier to re-enable.
Run the default Tomcat server (`CMD ["catalina.sh", "run"]`):
```console
$ docker run -it --rm %%IMAGE%%:8.0
$ docker run -it --rm %%IMAGE%%:9.0
```
You can test it by visiting `http://container-ip:8080` in a browser or, if you need access outside the host, on port 8888:
```console
$ docker run -it --rm -p 8888:8080 %%IMAGE%%:8.0
$ docker run -it --rm -p 8888:8080 %%IMAGE%%:9.0
```
You can then go to `http://localhost:8888` or `http://host-ip:8888` in a browser.
You can then go to `http://localhost:8888` or `http://host-ip:8888` in a browser (noting that it will return a 404 since there are no webapps loaded by default).
