Using @Docker For a Complex IoT Application | @DevOpsSummit [#DevOps]

The goal of any DevOps solution is to optimize multiple processes in an organization

The goal of any DevOps solution is to optimize multiple processes in an organization. And success does not necessarily require that in executing the strategy everything needs to be automated to produce an effective plan. Yet, it is important that processes are put in place to handle a necessary list of items.

Flux7 is a consulting group with a focus on helping organizations build, maintain and optimize DevOps processes. The group has a wide view across DevOps challenges and benefits, including:

  • The distinct challenge of a skills shortage in this area and how organizations are coping to meet demands with limited resources.
  • The technical requirements: From stacks to scripts, and what works.
  • The practical and political challenges: Beyond the stacks and the human element is a critical success factor in DevOps.

Recently at Flux7, we developed an end-to-end Internet of Things project that received sensor data to provide reports to service-provider end users. Our client asked us to support multiple service providers for his new business venture. We knew that rearchitecting the application to incorporate major changes would prove to be both time-consuming and expensive for our client. It also would have required a far more complicated, rigid and difficult-to-maintain codebase.

We had been exploring the potential of using Docker to set up Flux7's internal development environments, and, based on our findings, believed we could use it in order to avoid a major application rewrite. So, we decided to use Docker containers to provide quick, easy, and inexpensive multi-tenancy by creating isolated environments for running app tier multiple instances for each provider.

What is Docker?
Docker provides a user-friendly layer on top of Linux Containers (LXCs). LXCs provide operating-system-level virtualization by limiting a process's resources. In addition to using the chroot command to change accessible directories for a given process, Docker effectively provides isolation of one group of processes from other files and system processes without the expense of running another operating system.

In the Beginning
The "single provider" version of our app had three components:

  1. Cassandra for data persistence, which we later use for generating each gateway's report.
  2. A Twisted TCP server listening at PORT 6000 for data ingestion from a provider's multiple gateways.
  3. A Flask app at PORT 80 serving as the admin panel for setting customizations and for viewing reports.

In the past, we'd used the following to launch the single-provider version of the app:

12: nohup python tcp_server.py & # For firing up the TCP server.nohup python flask_app.py & # For firing up the admin panel

Both code bases were hard coded inside the Cassandra KEYSPACE.

Our New Approach
While Docker is an intriguing emerging technology, it's still in the early stages of development. As might be expected, it has issues remaining to be resolved. The biggest for us was that, at this point, Docker can't support multiple Cassandra instances running on a single machine. Consequently, we couldn't use Cassandra to provide multi-tenancy. Another issue for us was that hosting multiple database instances on a single machine can quickly cause resource shortages. We addressed that by implementing the solution in a fairly traditional way for making an application multi-tenant. We used KEYSPACE as the namespace for each provider in the data store. We also made corresponding code changes to both the data ingestion and web servers by adding the keyspace parameter to the DB accesses. We passed the Cassandra KEYSPACE (the provider ID) to each app instance on the command line, which makes it possible to use custom skins and other features in the future. Thus, we were able to create a separate namespace for each provider in the data store without making changes to the column family schema.

The beauty of our approach was that, by using Docker to provide multi-tenancy, the only code changes needed to make the app multi-tenant were those described above. Had we not used Docker in this way, we'd have had to make major code changes bordering on a total application rewrite.

How We Did It

Docker diagram 1.jpg

First, we created a Docker container for the new software version by correctly setting up all of the environments and dependencies. Next, we started a Cassandra container. Even though we weren't running multiple instances of Cassandra, we wanted to make use of Docker's security, administrative and easy configuration features. You can download our Cassandra file from our GitHub here.We used a locally running container serving at PORT 9160 BY using this command:

1

docker run -d -p 9160:9160 -name db flux7/cassandra

We then created a keyspace "provider1" using pycassaShell.

We fired up our two code bases on two separate containers like this:

12

docker run -name remote_server_1 -link db:cassandra -p 6001:6000 flux7/labs python software/remote_server.py provider1docker run -name flask_app_1 -link db:cassandra -p 8081:80 flux7/labs python software/flask_app.py provider1

view rawCode base launch in container hosted with ❤ by GitHub

Voila! We had a provider1 instance running in no time.

Automation
We found Docker-py extremely useful for automating all of these processes and used:

12345678910111213141516171819202122232425

# Yes. We love Python!def start_provider(provider_id, gateway_port, admin_port ):docker_client = docker.Client(base_url='unix://var/run/docker.sock'
version='1.6'
timeout=100) # start a docker container for consuming gateway data at gateway_portstart_command = 'python software/remote_server.py ' + provider_idremote_server = docker_client.create_container('flux7/labs', # docker image
command=start_command, # start command contains the keyspace parameter, keyspace is the provider_id
name='remote_server_' + provider_id, # name the container, name is provider_id ports=[(6000, 'tcp'),]) # open port for binding, remote_server.py listens at 6000docker_client.start(remote_server,
port_bindings={6000: ('0.0.0.0', gateway_port)},
links={'db': 'cassandra'}) # start a docker container for serving admin panel at admin_portstart_command = 'python software/flask_app.py ' + provider_idremote_server = docker_client.create_container('flux7/labs', # docker image
command=start_command, # start command contains the keyspace parameter, keyspace is the provider_id
name='admin_panel_' + provider_id, # name the container, name is provider_id
ports=[(80, 'tcp'),]) # open port for binding, remote_server.py listens at 6000docker_client.start(remote_server,
port_bindings={80: ('0.0.0.0',admin_port)},
links={'db': 'cassandra'})

view rawmulti-tenant-docker.py hosted with ❤ by GitHub

To complete the solution, we added a small logic to allocate the port for newly added providers and to create Cassandra keyspaces for each one.

Conclusion
In the end, we quickly brought up a multi-tenant solution for our client with the key "Run each provider's app in a contained space." We couldn't use virtual machines to provide that functionality because a VM requires too many resources and too much dedicated memory. In fact, Google is now switching away from using VMs and has become one of the largest contributors to Linux containers, the technology that forms the basis of Docker. We could have used multiple instances, but then we'd have significantly over allocated the resources. Changing the app also would have added unnecessary complexity, expense and implementation time.

At the project's conclusion, our client was extremely pleased that we'd developed a solution that met his exact requirements, while also saving him money. And we were pleased that we'd created a solution that can be applied to future customers' needs.

DevOps is a hot topic. It seems that everyone is talking about it. Some have built business models around DevOps-related tools and themes. There are conferences and trade shows dedicated to DevOps-strategies and techniques. Some people have even made their careers around talking about it.

I am not going to be one of many trying to create a buzzword-infested definition of DevOps to suit my particular agenda. Instead, I’d like to talk about what DevOps i...
