bosh-deployment

This repository is intended to serve as a reference and starting point for developer-friendly configuration of the Bosh Director. Consume the master branch. Any changes should be made against the develop branch (it will be automatically promoted once it passes tests).

Important notice for users of bosh-deployment and Bosh DNS versions older than 1.28

As of Bosh DNS version 1.28, Bosh DNS is now built with Go 1.15. This version of Go demands that TLS certificates be created with a SAN field, in addition to the usual CN field.

The following certificates are affected by this change and will need to be regenerated:

  • /dns_healthcheck_server_tls
  • /dns_healthcheck_client_tls
  • /dns_api_server_tls
  • /dns_api_client_tls

If you're using Credhub or another external variable store, then you will need to use update_mode: converge as documented here: https://bosh.io/docs/manifest-v2/#variables.
If you are not using Credhub or another external variable store, then you will need to follow the usual procedure for regenerating your certificates.

Jammy stemcells

We deploy using Jammy stemcells; however, if you would prefer to use the Bionic stemcells, append the ops files [IAAS]/use-bionic.yml and misc/source-releases/bosh.yml after the ops file [IAAS]/cpi.yml.

How is bosh-deployment updated?

An automatic process updates Bosh, and other releases within bosh-deployment

  1. A new release of bosh is created.
  2. A CI pipeline updates bosh-deployment on develop with a compiled bosh release.
  3. Smoke tests are performed to ensure create-env works with this potential collection of resources and the new release.
  4. A commit to master is made.

Other releases such as UAA, CredHub, and various CPIs are also updated automatically.

Using bosh-deployment

Ops files

  • bosh.yml: Base manifest that is meant to be used with different CPI configurations
  • [alicloud|aws|azure|docker|gcp|openstack|softlayer|vcloud|vsphere|virtualbox]/cpi.yml: CPI configuration
  • [alicloud|aws|azure|docker|gcp|openstack|softlayer|vcloud|vsphere|virtualbox]/cloud-config.yml: Simple cloud configs
  • [alicloud|aws|azure|docker|gcp|openstack|vcloud|virtualbox|vsphere|warden]/use-bionic.yml: use Bionic stemcell instead of Jammy stemcell
  • jumpbox-user.yml: Adds user jumpbox for SSH-ing into the Director (see Jumpbox User)
  • uaa.yml: Deploys UAA and enables UAA user management in the Director
  • credhub.yml: Deploys CredHub and enables CredHub integration in the Director
  • bosh-lite.yml: Configures Director to use Garden CPI within the Director VM (see BOSH Lite)
  • syslog.yml: Configures syslog to forward logs to some destination
  • local-dns.yml: Enables Director DNS beta functionality
  • misc/config-server.yml: Deploys config-server (see credhub.yml)
  • misc/proxy.yml: Configure HTTP proxy for Director and CPI
  • misc/dns.yml: Configure your upstream DNS (NOTE: by default bosh-deployment uses Google DNS: 8.8.8.8)
  • misc/ntp.yml: Configure your NTP Servers (NOTE: by default bosh-deployment uses Google NTP servers: time{1-4}.google.com
  • runtime-configs/syslog.yml: Runtime config to enable syslog forwarding

See tests/run-checks.sh for example usage of different ops files.

Runtime Config Files

The director can optionally add configuration to all VMs in all deployments. The YAML defines an IaaS agnostic configuration that applies to all deployments. (See Director Runtime Config.)

  • dns.yml: Install bosh defined dns release in every deployed VM. This allows bosh VMs to use the VM name as a FQDN. It is extremely common for deployments require this addon. (eg concourse-ci with UAA). For more information see Native DNS Support.
  • bpm.yml: Install bosh process manager on every VM (see BPM-Release)
  • syslog.yml: Install a syslog forwarder agent in every VM.

Runtime config files are applied after bosh director has been deployed:

bosh -n -e bosh-1 update-runtime-config bosh-deployment/runtime-configs/dns.yml

See runtime-configs/ for examples of different runtime configs. Other uses include installation of prometheus exporters, os-conf (to modify os level configurations), virus scanning, compliance agents.
