Container-Based CI/CD with CloudBees Core on Kubernetes

Getting to Know Jenkins

CI/CD is an imperative for software development organizations in today’s multiplatform, multi-cloud world. As far as CI/CD platforms go, Jenkins was one of the first and remains one of the most popular options. Jenkins is lightweight, easy, and extensible. The multitude of plugins available make the platform endlessly customizable and adaptable to any workflow. As soon as your Jenkins slave is online, you can start running remote shell commands with a freestyle job.

Jenkins can also be a double-edged sword though: plugin mismatches, slave configuration drift, CPU spikes, and disk exhaustion can arise. If you are still running Jenkins on traditional VMs or bare-metal infrastructure, some of these symptoms may be familiar to you. Even with the high-value features of CloudBees such as improved RBAC and folder permissions, Operations Center, and Elasticsearch-based monitoring, Jenkins can be difficult to manage for large organizations with high-capacity needs, limited infrastructure, and a diverse population of users. While CI/CD has become critically important for organizations to stay competitive and Jenkins is one of the most widely used solutions in this space, a host of issues can occur while using Jenkins without frequent planning and a skilled support team.

CI/CD with Containers

The combination of CI/CD and software containers can immediately address some of the challenges just mentioned. Containers images can be used as immutable, ephemeral Jenkins slaves, nearly eliminating the possibility of drift. Container images can also be used for the Jenkins Master, then scaling out to a new master becomes as easy as a few clicks. Disk space exhaustion becomes as easy as a docker container prune command. CI/CD using software containers is a compelling use case, and is slowly becoming the new norm for development organizations. Aside from Jenkins, this is the core behavior of other CI/CD tools such as Drone, GitLab, Codefresh, and CircleCI.

CloudBees Core on Kubernetes

CloudBees Core marries the enterprise-readiness of CloudBees Jenkins with the scalability and simplicity of container-powered CI/CD. Leveraging Kubernetes as an underlying platform, CloudBees Core allows organizations to scale CI/CD more easily and simplify the management of Jenkins across the organization.
