Editor's Notes
- Value Context: - Develope Faster - Less Boilerplate code, less errors - CI/CD – Automated integrating and deployment to production - Elasticity - Improved DevOps
- Lose Diego Cell Page out To Garrent after BMC patrol 10 min Determine VM is dead – 15-30 Create a new VM from a template – 10 Minutes Add IP network - 10 minutes ACLs, etc, chef Install chef: 15 min – 30 min Best Case 2-3 hours PCF Auto rebalances lost apps/services to available cells
- Between Round 2 and Rount 3, the project got pushed in May 2017due to priorities, and picked up again in Early 2018.
- Lose Diego Cell Page out To Garrent after BMC patrol 10 min Determine VM is dead – 15-30 Create a new VM from a template – 10 Minutes Add IP network - 10 minutes ACLs, etc, chef Install chef: 15 min – 30 min Best Case 2-3 hours PCF Auto rebalances lost apps/services to available cells
- How quickly does the pipeline Efficient and Effective
- Keep everything in one tool
- Bot fetches release notes for stemcell and tile. Bot should be able to know which foundation and which tile using params set on the pipeline Bot should know if the stemcell version is updated Bot should know if the tile version is updated
- Continuous integration environment would take the glob pattern for the product version and stemcell and upload and apply the changes to the ci environment when a version is published to pivnet that matches the glob pattern.
- Pool Locks - ensures that only one change is flowing at a time multiple pipelines can be running at a time but only one will be able to apply the changes when the updates succeed to be applied a PR will be created to the next foundation in the chain
