Docker Cookbook

270 | Chapter 8: Docker in the Cloud

Once it is ready, you can push your Docker application to it. This is most easily done
by using the 
eb
CLI, which unfortunately is not included in the 
awscli
. To finish the
deployment, you will perform the following steps:
1. Install the 
awsebcli
.
2. Create your Dockerfile.
3. Initialize the application 
foobar
that you created earlier.
4. List the environment to make sure you are using the 
cookbook
environment cre‐
ated previously.
5. Deploy the application.
Let’s do this: install 
awsebcli
, and create your application directory with our Docker‐
file in it:
$ sudo pip install awsebcli
$ mkdir beanstalk
$ cd beanstalk
$ cat > Dockerfile
FROM ubuntu:12.04
RUN apt-get update
RUN apt-get install -y nginx zip curl
RUN echo "daemon off;" >> /etc/nginx/nginx.conf
RUN curl -o /usr/share/nginx/www/master.zip -L https://codeload.github.com/ \
gabrielecirulli/2048/zip/master
RUN cd /usr/share/nginx/www/ && unzip master.zip && mv 2048-master/* . && \
rm -rf 2048-master master.zip
EXPOSE 80
CMD ["/usr/sbin/nginx", "-c", "/etc/nginx/nginx.conf"]
You can then use the 
eb
CLI to initialize the application (using the application name
used in the preceding steps—
foobar
) and deploy it with 
eb deploy
:
$ eb init foobar
$ eb list
* cookbook
$ eb deploy
Creating application version archive "app-150331_181300".
Uploading foobar/app-150331_181300.zip to S3. This may take a while.
