0 likes114 views
The document outlines the functionalities and principles of BOSH, an open-source tool developed to manage Cloud Foundry PaaS deployments. It describes BOSH's ability to automate the lifecycle management of virtual machines, software packages, and other cloud resources while emphasizing its features like predictability, repeatability, and self-healing. Additionally, it provides details on configuration management and deployment processes across various cloud infrastructure providers.
OSDC 2017 - Justin Carter - Orchestrating a platform with BOSH
- 1. Operating a platform with BOSH Open Source Data Center 2017, Justin Carter (@bodymindarts) Berlin, 17. Mai 2017 Stark & Wayne
- 4. ‘BOSH is Cloud Foundry community’s special sauce that others ignore at their own peril’ - Dr. Nic Williams (CEO Stark & Wayne)
- 5. Background Cloud Foundry PaaS developed by VMWare - Open Sourced in 2011 BOSH (Bosh Outer SHell) developed to deploy CF - Open Sourced in 2012 BOSH v2 features released in 2016 / 2017
- 6. Platforms A layer of software between IaaS and SaaS to automate and orchestrate the provisioning, running and management of cloud applications.
- 7. Platforms Top layer of the cloud automation stack
- 8. Complex distributed systems Platforms: operations Many internal dependencies Require sophisticated tooling to deploy, operate, update, scale
- 9. micro-bosh - BOSH deployed onto a single VM bosh-lite - micro-BOSH deployed onto VirtualBox (for dev, uses warden containers as IaaS) BOSH: flavours BOSH - multi-component, potentially distributed bosh-init - CLI to bootstrap a (micro-)BOSH
- 11. BOSH: what does it do? Manages lifecycle of vms Installs and configures software packages Runs and monitors processes Manages lifecycle of persistent disks via CPI via CPI via agent via monit
- 12. BOSH: principles Predictability - State of entire deployment is described declaratively Repeatability - Operations are idempotent and completely versioned Self-healing - Continuous reconciliation of desired with actual state of vms and processes
- 13. Dummy platform Server nomad consul Server nomad consul Server nomad consul HA, distributed, nomad cluster Node nomad-agent consul-agent https://www.nomadproject.io/ https://www.consul.io/ Node nomad-agent consul-agent Node nomad-agent consul-agent
- 14. BOSH: configuration the deployment manifest declares releases - Software packages instance_groups - configuration and scaling of vms stemcells - OS image to use
- 15. network - referencing cloud_config releases - Software packages instance_groups - vm configuration referencing cloud_config stemcells - OS image to use jobs - process allocation properties - process configuration Deployment Manifest
- 16. BOSH: configuration the cloud config declares IaaS specific configuration azs - Name of availability zones on this IaaS networks - Configuration of networks and sec. groups vm_types - Configuration of vms disk_types - Configuration of persistent disks
- 18. BOSH: configuration deployment manifest / cloud config split enables portability between cloud infrastructure providers Supported providers include: AWS, GCP, Azure, vSphere, OpenStack
- 19. bosh deploy Deploy or converge a running system to a desired state
- 22. BOSH release: packages - Blobs & compilation scripts jobs - Configuration files & scripts that run processes blobs - Source code and pre-compiled binaries
- 25. packages - reference templates - config files links - Runtime dependencies properties - Config options Job Spec
- 28. bosh upload stemcell Upload a new version of an os image to the cloud and make it available for future deployments
- 30. BOSH release:
- 31. bosh upload release Upload a new version of a BOSH release to the cloud and make it available for future deployments
