Introduction to OpenDevStack
What is OpenDevStack?
When we started with RedHat’s OpenShift we were blown away by the 100s of possibilities to use it, but there was not anything along the lines of "This is how you make it work for your org". Its catalog provides items for almost everything - yet what we wanted is to enable people to quickly introduce Continous Delivery and standardized technology archetypes. We call this lean, empowered governance.
So what does OpenDevStack provide?
Everyting you need for CI infrastructure (Jenkins images, SonarQube, Nexus).
Ansible playbooks to install the Atlassian suite (Jira, Bitbucket, Confluence, Crowd).
A shared jenkins library that harmonizes the way you build, test, govern and deploy.
A set of technology quickstarters that provide complete CI/CD integration, w/o anything to worry about for the engineer.
A small provisioning application that gives you one place to start, no matter if you want to start a new project, or enhance an existing one with a quickstarter.
Create a new project
Trigger project creation through the provisioning application to get a new project. The web GUI of the provisioning app is located at
When "Create Openshift Project" is checked, this will also create OpenShift projects, namely
A Jenkins deployment will be created in the
<project-key>-cd project to allow each project full freedom of build management. This deployment is based on a common Jenkins image from the central ODS namespace.
Create a new component within a project (using a quickstarter)
Open the web GUI of the provisioning app
Select your project, then choose a quickstarter. If no framework fits to your needs, choose the docker-plain quickstarter.
After provisioning the quickstarter, you’ll have a new repository in your BitBucket project with the boilerplate of the component. From that, a Jenkins job is triggered automatically (via a webhook setup in Bitbucket) which builds and deploys the boilerplate application into the
Major releases of OpenDevStack happen roughly every half year. Each major release is identified by a version such as
4 and so on. As a consumer of OpenDevStack, you can either:
masterto follow the cutting edge
3.x, etc. to stay on a major version, but get bug fixes (minor versions)
v3.0, etc. to pin an exact version
use a custom branch / tag such as
3.custometc. to run ODS with customizations
A major update (e.g.
4.x) is, from a user perspective, an explicit update. This means that even if admins update the ODS installation in the cluster, users still have to adopt that change (e.g. by updating their Jenkins image reference and so on). Therefore, a major version change is accompanied by an update guide like Update to 3.x. For admins, a major update might mean that configuration options have to be changed or migration steps to be taken, as well as rebuilding and rolling out all images etc.
A minor update (consuming changes/bugfixs on a release branch such as 3.x). From a user perspective, this is an implicit update. This means that only admins have to make a change to the ODS installation in the cluster. Users must get those changes automatically, without the need to explicitly adopt it. Therefore, there is no update guide for minor updates. For admins, a minor update should not require changing configuration options nor performing migration steps - only rebuilding and rolling out some (or all) images should be needed.
Each version is tracked as a GitHub project. The current major version is 3, the next one will be 4.
4 (Target date: December 2020)
Planned work (subject to change):
