This document discusses DevOps workflows using OpenShift and ManageIQ. It describes using GitLab for source code management, CI/CD, and collaboration. OpenShift is used as a platform for deploying and managing containerized applications. ManageIQ orchestrates provisioning of the DevOps tools including FreeIPA for authentication, GitLab, and OpenShift. The ecosystem is integrated through a CI/CD pipeline that builds, tests, reviews, and deploys code changes from a Git repository to OpenShift.

10. Ecosystem
10
FreeIPA - Authentication, users and groups management
GitLab - Source Code Management, Review, Ticketing, Documentation, Pastebin
OpenShift - Platform-as-a-Service
ManageIQ - Cloud Management Platform, Orchestrator

11. Ecosystem / FreeIPA
11
Integrated security information management solution
Provides centralized authentication, authorization and account information
Based on standards open source implementation :
- LDAP - 389 Directory Server
- DNS - Bind w/ LDAP backend
- Kerberos - MIT
- PKI - Dogtag
Along with CLI and web interface.
Bi-directional Active Directory integration.
⇒ Used for consistent authentication, DNS and certificates.

12. Ecosystem / GitLab
12
The core of our configuration management:
- Source code management, based on Git
- Tickets management: issues, enhancements, whatever...
- Code review through Merge Requests
- Continuous Integration engine

13. Ecosystem / OpenShift Origin
13
Platform-as-a-Service
- Leverages Docker & Kubernetes to deploy applications seemlessly
- Build your container from Source (Git) or Dockerfiles
- Deploy any Docker image with advanced scheduling
- Manage your application lifecycle: blue/gree, A/B, etc…
- Integrate with Eclipse

Should I really present it ?
Used to orchestrate the provisioning of our DevOps tooling.

25. Implementation details
Serialize data in Automate tree as instances ⇒ waiting for generic objects
Deploy children services from buttons and REST API
Lot of rework on dialogs along the time, to reduce the number of questions
Test, test, test… Thanks to the API.

28. Next steps
Create a Mattermost team per project
Allow for more Lifecycles (don't assume)
Deploy .gitlab-ci.yml for each lifecycle
Anything from field feedback...
