1.13 Bosh Concepts List

Name	Comment
Bosh Stemcells	A versioned Operating System image. Download stemcell
Bosh Deployment	An encapsulation of software and configuration that BOSH can deploy to the cloud.
Bosh Release	Everything needed to make a software component deployable by BOSH.

Bosh Package	It contains vendored in software source and scripts to compile it.
Bosh Errand	A short-lived job that can be triggered by an operator any time after the deploy.
Bosh Tile	A *.pivotal file with everything needed to install/upgrade a PCF service. Tile CheatSheet
Bosh Manifest	A YAML file that identifies one or more releases, stemcells and configurations
Bosh ops file	A YAML file that includes multiple operations to be applied to a different YAML file.
Bosh Event	Actions taken by the Director (via user or system control) are recorded as events
Bosh Director	The Director is the orchestrator of deployments.
Bosh Addon	A release job that is colocated on all VMs managed by the Director.
Bosh Agent	A process that runs continuously on each VM that BOSH deploys. one Agent process per VM
Bosh Jumpbox	A VM that acts as a single access point for the Director and deployed VMs.
Director Blobstore	A repository where BOSH stores release artifacts, logs, stemcells, and other content, etc
Cloud ID (CID)	ID returned from the Cloud identifying particular resource such as VM or disk.

1.14 Bosh Stemcell

1.15 Bosh Monit

Name	Comment
List bosh deployed daemon processes	`sudo su -`, `monit summary`, `watch 'monit summary'`
Restart a given daemon processes	`monit restart <process_name>`
Check a given daemon processes status	`monit status <process_name>`

bpm BOSH process manager	Isolation of BOSH jobs to make they run on many different work schedulers instead of monit only

1.17 Bosh Challenges

Name	Comment
Create deployment is very slow	Need to compile packages again, and canary update for all VMs
Errands on non co-located vms	It takes 5+ minutes to spin up and destroy a VM
No repo mechanism for Bosh releases	Duplicate packages are required to make no external dependencies
Support `tail -f`	Personally I don’t like the way of `bosh logs`
Retry a failed errand/task	Currently we can do it. But it’s a lengthy manual process
More lightweight	Use `containers`, instead of `VMs` to run errands
Support rolling upgrade	Just like `kubectl rollout`
More declarative	End users define requirements via `yaml files`
