First Hand Experience on the Path to Continuous Deployment for Docker Containers

Being experienced  startup folks we are not scared of bleeding edge tech. For instance, in 2005 we made the jump to virtual machines  when most companies hadn't even heard of virtualization, in order to create our cloud platform, AppLogic. This time around we were already very familiar with containers, including many of the limitations, and believed they offered a lot of advantages in speed and cost so we decided to go with Docker running on AWS.

Our engineers have written a lot of apps including both interactive user apps and infrastructure level services and we're pretty adept at creating stateless systems where that's possible. Unfortunately, some of the third party software we needed to use, especially open source, wasn't written with stateless in mind.

For us combining Dev and Ops wasn't a choice, but a necessity. We couldn't afford another hire to run ops. Nonetheless we're fanatics for DevOps and automating everything we can in build, test and deploy. In our case the role of the DevOps guru fell on Pavel, one of our senior engineers. He's well versed in systems architecture as well as most of the systems that needed to be touched by the automation.

Introducing VCTR
The app we were bringing out is called Victor (VCTR for Vulnerabilities and Configuration Tracking and Reporting), a free online service that scans containers and VMs for upgrades that fix critical vulnerabilities. You can check out VCTR here.

As we progressed through development some things worked exceptionally well. New tools including Slack made collaboration among a dispersed team very easy. Build and test tools including Jenkins worked as expected though they were a bit harder to set up than they should be. Docker, despite some minor issues, was more mature than we expected. As you probably have guessed, though, there's a "however" coming. In our case, that "however" was that deployments were still complicated and error prone.

As we got started our deployment was managed part-time by Pavel, our senior engineer. After all, the literature available suggested he'd just be writing a few short pipeline scripts. At first this worked great, but since change is inevitable, things got complicated. VCTR began expanding as new features were integrated and Pavel's day job became wrangling an unruly set of deployment scripts. Of course, as he spent time on deployment he wasn't contributing to building VCTR. As Pavel got sucked further and further into script hell with each new change, he noticed he'd fallen into a pattern:

  1. understand changes -> understand current app -> write script

  2. test script -> debug -> deploy

  3. fail -> debug again -> redeploy

  4. manual rollback...

  5. give up

The options were minimal. Either we continue to fail through this deployment until we got it right, or find another solution to the problem

Deployment Pain
Despite deployment issues hindering our velocity we needed to push forward with VCTR so we started user engagement while looking for solutions. We assumed we'd find a new tool or pattern in time, but things took an unexpected turn. While implementing VCTR we found other folks having similar deployment issues. Bringing up a new user with VCTR requires installing a small piece of code in the container or VM. That process, not surprisingly, happens in a deployment script and in most cases inserting that one change caused a failure in deployment. In one instance, while on a video call with a user, we watched as a five minute change to one script turned into a two hour debugging marathon involving more than half a dozen scripts. The only folks who didn't have errors after making the change had actually recognized deployment as a significant issue and built their own system for it. Systems, so significant in the amount of time they took to build that they were given names and teams to maintain them. However, those systems were tied to their company's specific architecture and tool chain.

The heart of the problem is that despite articles to the contrary, containers and microservices have dependencies. Some dependencies are simple. For instance, some software still have start order dependencies. Others require configuration differences based on the environment they're running in. Still other require logging in and executing commands after startup. Some dependencies you create yourself. As an example, changing an API requires updates to both the providing and calling services. You might require all updates to be backward compatible, but that's just moving the work to what may be an even more complicated arena. Lastly, what happens when something fails? How do you find out what failed? How do you get back to a functional state?

Despite mounting evidence we didn't initially recognize the pattern. One day over lunch, as the discussion turned from VCTR to deployment issues we realized we'd seen similar problems before when we first tackled cloud deployment. Furthermore, we knew we could solve this. We decided to build a continuous deployment system.

Lessons Learned
We obviously learned a ton about what not to do when setting up a new containerized application. Here's our conclusion of the good and bad of containers, microservices and DevOps:

The good

  • Containers, though not perfect, have a rich enough ecosystem of tools to be used in production.
  • Microservices architectures are great but don't try to make everything stateless.
  • DevOps is the new norm, but you need to go beyond just assigning an engineer the title or merging the folks onto a single team. Ops must take on a new role defining use cases and Dev must embrace Ops.
  • Get your tool chain in place from the start. We tried to hack our deployments and as such didn't see the problem for what it was until we were knee deep in it.

The bad

  • Deployment remains hard because it's where software meets the real world.
  • Deployment requires a system once you get past a few containers. If you don't adopt one, you're going to end up building one - whether you realize it or not.
  • Scripts work fine for small apps that don't get updated often, but aren't up to the task for continuous deployment for apps that contain more than a few containers or microservices, especially those that are updated frequently.

The Result - Continuous Deployment System

We identified key challenge patterns that both ourselves and others faced during deployment and turned them into solutions. One important difference to the other deployment systems we had seen was that we made sure to build for varied environments and architectures. We didn't want this tool to just work for us or rather just the current pattern we were working in. We needed a true system to grow with us. Here are some of the main requirements of our Continuous Deployment system:

  • Integrate with popular tool chain elements
  • Recognize code and architecture updates
  • Provide for identifying dependencies
  • Provide for various operating environments
  • Automatically deploy authorized updates to operating environments
  • Automatically correct for common errors to return proper operation
  • Provide meaningful logs and error messages
  • Be operable from either UI, API or completely autonomously

We built this deployment system and it's now deploying VCTR on a regular basis. It's also in production at InnoScale and being tested by a handful of DevOps teams who felt the same pain as we did. We're offering the system for free to teams for up to 15 containers.

From Apollo 13 to Google SRE: When DevOps met SRE

The complexity of managing and delivering the high level of reliability expected of web-based, cloud hosted systems today, and the expectation of Continuous Delivery of new features has led to the evolution of a totally new field of Service Reliability Engineering catered for such systems.
Google, who has been a pioneer in this field, calls it Site Reliability Engineering (SRE). While it would be more aptly named Service Reliability Engineering, the name has caught on. The seminal work documenting Google approach and practices is in the book by Google by the same name (commonly referred to as the ‘SRE book'), and has become the defacto standard on how to adopt SRE in an organization. This session will cover adopting SRE as a practice in organizations also adopting DevOps; address the challenges to adopting SRE faced by large traditional enterprises, and how to overcome them.

Cloud-Native: A New Ecosystem for Putting Containers into Production

The standardization of container runtimes and images has sparked the creation of an almost overwhelming number of new open source projects that build on and otherwise work with these specifications.

Of course, there's Kubernetes, which orchestrates and manages collections of containers. It was one of the first and best-known examples of projects that make containers truly useful for production use. However, more recently, the container ecosystem has truly exploded. A service mesh like Istio addresses many of the challenges faced by developers and operators as monolithic applications transition towards a distributed microservice architecture. A tracing tool like Jaeger analyzes what's happening as a transaction moves through a distributed system. Monitoring software like Prometheus captures time-series events for real-time alerting and other uses. Grafeas and Kritis provide security policy attestation and enforcement. And there are many more.

In short, there's an entire new cloud-native ecosystem growing up around containers. Come to this talk by Red Hat technology evangelist Gordon Haff and learn all about it.

DevSecOps: The Open Source Way

DevOps purists may chafe at the DevSecOps term given that security and other important practices are supposed to already be an integral part of routine DevOps workflows. But the reality is that security often gets more lip service than thoughtful and systematic integration into open source software sourcing, development pipelines, and operations processes--in spite of an increasing number of threats.

The extensive use of modular open source software from third-parties, distributed development teams, and rapid iterative releases require a commitment to security and the adoption of security approaches that are continuous, adaptive, and heavily automated.

In this session, Red Hat Technology Evangelist Gordon Haff look at successful practices that distributed and diverse teams use to iterate rapidly.  While still reacting quickly to threats and minimizing business risk. I'll discuss how a container platform can serve as the foundation for DevSecOps in your organization. I'll also consider the risk management associated with integrating components from a variety of sources--a consideration that open source software has had to deal with since the beginning. Finally, I'll show ways by which automation and repeatable trusted delivery of code can be built directly into a DevOps pipeline.

Accelerating CI/CD with Data Management On Premise and Cloud

Updating DevOps to the latest production data slows down your development cycle. Probably it is due to slow, inefficient conventional data management practices to copy data between different developer and test environment. This problem doesn't scale as teams are adopting faster software release cycles.

In this session, Dhiraj Sehgal in Product and Solution at Delphix, will talk about DevOps and cloud-focused strategies to update hundreds of developer and test copies with updates from a master database in minutes, saving hours or even days in each development cycle. He will also discuss how new practices in DataOps to manage data across multiple sources is making their life easier and helps  becoming invisible to developers for data provisioning.

Cloud computing is now being embraced by a majority of enterprises of all sizes. Yesterday's debate about public vs. private has transformed into the reality of hybrid cloud: a recent survey shows that 74% of enterprises have a hybrid cloud strategy. Meanwhile, 94% of enterprises are using some form of XaaS - software, platform, and infrastructure as a service.

With major technology companies and startups seriously embracing Cloud strategies, now is the perfect time to attend and learn what is going on, contribute to the discussions, and ensure that your enterprise is on the right path to Digital Transformation.

Every Global 2000 enterprise in the world is now integrating cloud computing in some form into its IT development and operations. Midsize and small businesses are also migrating to the cloud in increasing numbers.
