In Part 1 of this blog, I talked about how Red Hat has been working with the open source community to build a new container stack and our commitment to bring that to OpenStack. In Part 2 I will discuss additional capabilities Red Hat is working on to build an enterprise container infrastructure and how this is forms the foundation of our containerized application platform in OpenShift.
As we discussed in the previous post, Linux, Docker and Kubernetes form the core of Red Hat’s enterprise container infrastructure. This LDK stack integrates with OpenStack’s compute, storage and networking services to provide an infrastructure platform for running containers. In addition to these areas, there are others that we consider critical for enterprises who are building a container-based infrastructure. A few of these include:
Container Security - Red Hat is working with Docker and the Open Containers community on container security. Security is commonly cited as one of the leading concerns limiting container adoption and Red Hat is tackling this on multiple levels. The first is multi-tenant isolation to help prevent containers from exploiting other containers or the underlying container host. Red Hat contributed SELinux integration to Docker, to provide a layered security model for container isolation and is also contributing to the development of features like privileged containers and user namespaces. The second area is securing container images to verify trusted content, which is another key concern. Red Hat has driven innovation in areas like image signing, scanning and certification and we recently announced our work with Black Duck to help make application containers free from known vulnerabilities
Enterprise Registry - Red Hat provides a standard Docker registry as a fully integrated component of both OpenShift and Atomic. This enables customers to more securely store and manage their own Docker images for enterprise deployments. Administrators can manage who has access to images, determine which images can be deployed and manage image updates.
Logging & Metrics - Red Hat has already integrated the ELK stack with Red Hat Enterprise Linux OpenStack Platform. It is doing the same in OpenShift and Atomic to provide users with aggregate logging for containers. This will enable administrators to get aggregated logs across the platform and also simplify log access for application developers. This work extends into integrated metrics for containerized applications and infrastructure.
Container Management - Red Hat CloudForms enables infrastructure and operations teams to manage application workloads across many different deployment fabrics - physical, virtual, public cloud and also private clouds based on OpenStack. CloudForms is being extended to manage container-based workloads in its next release. This will provide a single pane of glass to manage container-based workloads on OpenStack infrastructure.
Ultimately the goal of containers is to provide a better way to package and deploy your applications and enable application developers. Containers provide many benefits to developers like portability, fast deployment times and a broad ecosystem of packaged container images for a wide array of software stacks. As applications become more componentized and highly distributed with the advent of microservices architectures, containers provide an efficient way to deploy these microservices without the overhead of traditional VMs.
But to provide a robust application platform and enable DevOps and Continuous Delivery, we also need to solve other challenges. Red Hat is tackling many of these in OpenShift, which is a containerized application platform that natively integrates Docker and is built on Red Hat’s enterprise container stack. These challenges include:
Build Automation - Developers moving to containerize their applications will likely need to update their build tools and processes to build container images. Red Hat is working on automating the Docker image build process at scale and has developed innovations like OpenShift source-to-image which enables users to push code changes and patches to their application containers, without being concerned with the details of Dockerfiles or Docker images.
Deployment Automation and CI/CD - Developers will also need to determine how containers will impact their deployment workflows and integrate with their CI/CD systems. Red Hat is working on automating common application deployment patterns with containers like rolling, canary and A/B deployments. We are also working to enable CI/CD with containers with work underway in OpenShift upstream projects like Origin and Fabric8
Containerized Middleware and Data Services - Administrators will need to provide their developers with trusted images to build their applications. Red Hat provides multiple language runtime images in OpenShift including Java, Node.js, Python, Ruby and more. We are also providing containerized middleware images like JBoss EAP, A-MQ and Fuse as well as database images from Red Hat’s Software Collections including MongoDB, Postgres and MySQL.
Developer Self Service - Ultimately developers want to access all of these capabilities without having to call on IT. With OpenShift, developers can access self-service Web, CLI and IDE interfaces to build and deploy containerized applications. OpenShift’s developer and application-centric view provide a great complement to OpenStack.
This is just a sampling of the work we are doing in Containers and complements all the great work Red Hat contributes to in the OpenStack community. OpenStack and Containers are two examples of the tremendous innovation happening in open source and this week we are showcasing how they are great together. We hope you will join us in Tokyo to learn more!
