## Dockerfile examples ## Dockerfile examples
Below you can see some examples of Dockerfile syntax. For examples of Dockerfiles, refer to:
```dockerfile - The ["build images" section](https://docs.docker.com/develop/develop-images/dockerfile_best-practices/)
# Nginx - The ["get started](https://docs.docker.com/get-started/)
# - The [language-specific getting started guides](https://docs.docker.com/language/)
# VERSION 0.0.1
FROM ubuntu
LABEL Description="This image is used to start the foobar executable" Vendor="ACME Products" Version="1.0"
RUN apt-get update && apt-get install -y inotify-tools nginx apache2 openssh-server
```
```dockerfile
# Firefox over VNC
#
# VERSION 0.3
FROM ubuntu
# Install vnc, xvfb in order to create a 'fake' display and firefox
RUN apt-get update && apt-get install -y x11vnc xvfb firefox
RUN mkdir ~/.vnc
# Setup a password
RUN x11vnc -storepasswd 1234 ~/.vnc/passwd
# Autostart firefox (might not be the best way, but it does the trick)
RUN bash -c 'echo "firefox" >> /.bashrc'
EXPOSE 5900
CMD ["x11vnc", "-forever", "-usepw", "-create"]
```
```dockerfile
# Multiple images example
#
# VERSION 0.1
FROM ubuntu
RUN echo foo > bar
# Will output something like ===> 907ad6c2736f
FROM ubuntu
RUN echo moo > oink
# Will output something like ===> 695d7793cbe4
# You'll now have two images, 907ad6c2736f with /bar, and 695d7793cbe4 with
# /oink.
