BOSH Notes

Because BOSH documentation is sparse and out of date, I've compiled these notes to help with future work.

Assumptions

  • ubuntu with ruby installed
  • install keypair for use with github

Use Fog to Create an Inception VM

  1. gem install fog
  2. create key pair specifically for fog
  3. create a fog config:
:default:
  :aws_access_key_id:     YOUR_ACCESS_KEY
  :aws_secret_access_key: YOUR_SECRET_KEY
  :private_key_path: '/Users/shane/.ssh/fog_rsa'
  :public_key_path: '/Users/shane/.ssh/fog_rsa.pub'
  1. type fog, then follow steps below:
connection = Fog::Compute.new({ :provider => 'AWS', :region => 'us-east-1' })

Import key pair

Fog.credentials = Fog.credentials.merge({ :private_key_path => "/Users/shane/.ssh/fog_rsa", :public_key_path => "/Users/shane/.ssh/fog_rsa.pub" })
connection.import_key_pair('shane-fog', IO.read('/Users/shane/.ssh/fog_rsa.pub')) if connection.key_pairs.get('shane-fog').nil?

Boostrap new instance and associate EIP

server = connection.servers.bootstrap({:key_name => 'shane-fog', :flavor_id => 'm1.small', :bits => 64, :username => 'ubuntu'})

address = connection.addresses.create
address.server = server
server.reload
server.dns_name

Create a volume and mount it to the new instance

volume = connection.volumes.create(:size => 16, :device => "/dev/sdi", :availability_zone => server.availability_zone)
volume.server = server

server.ssh(['sudo mkfs.ext4 /dev/sdi -F'])
server.ssh(['sudo mkdir -p /var/vcap/store'])
server.ssh(['sudo mount /dev/sdi /var/vcap/store'])
puts server.ssh(['df']).first.stdout

Create security group

connection = Fog::Compute.new({ :provider => 'AWS', :region => 'us-east-1' })
connection.security_groups.create name: "microbosh", description: "microboshes"
group = connection.security_groups.get("microbosh")
group.authorize_port_range(25555..25555) # BOSH Director API
group.authorize_port_range(6868..6868)   # Message Bus
group.authorize_port_range(25888..25888) # AWS Registry API
group.authorize_port_range(22..22)       # SSH access

quit fog

Connect to inception instance and run prepare_inception script

ssh -i /Users/shane/.ssh/fog_rsa [email protected]
sudo su -

export ORIGUSER=ubuntu
curl -s https://raw.github.com/drnic/bosh-getting-started/master/scripts/prepare_inception.sh | bash
source /etc/profile

Procedure

Now that the inception vm is created, start the edit/build/deploy cycle.

In an effort to save time with downloading and uploading artifacts, the following steps were all done on an EC2 instance (the inception vm created above).

  1. forked cloudfoundry/bosh to cinderella/bosh in order to make changes necessary for Cinderella.
  2. make changes and commit to cinderella/bosh
  3. cd ..
  4. Check out bosh-release: git clone https://github.com/cloudfoundry/bosh-release.git
  5. cd bosh-release
  6. git submodule update --init
  7. bosh create release --with-tarball (will create manifest and tarball in bosh-release/dev_releases needed in step 10)
  8. cd ../bosh/agent
  9. bundle install
  10. extra packages needed: sudo apt-get install debootstrap kpartx
  11. create stemcell from manifest and tarball created in step 6 (from bosh/agent): rake stemcell2:micro[aws,/root/projects/bosh-release/dev_releases/cinders-10.1-dev.yml,/root/projects/bosh-release/dev_releases/cinders-10.1-dev.tgz] ...
    Generated stemcell: /var/tmp/bosh/agent-0.6.7-18060/work/work/micro-bosh-stemcell-aws-0.7.0.tgz
  12. cd /var/vcap/deployments
  13. gem install bosh_deployer
  14. select cinders deployment: bosh deployment cinders WARNING! Your target has been changed to `http://cinders:25555'! Deployment set to '/var/vcap/deployments/cinders/micro_bosh.yml'
  15. do actual deploy of micro bosh stemcell: bosh deploy /var/tmp/bosh/agent-0.6.7-18060/work/work/micro-bosh-stemcell-aws-0.7.0.tgz
