Cloud Foundry Stacks

This repo contains scripts for creating warden root filesystems.

  • cflinuxfs2 derived from Ubuntu 14.04 (Trusty Tahr)

Dependencies

  • GNU make
  • Docker

Adding a new package to the rootfs

cflinuxfs2/build/install-packages.sh has a list of packages passed to apt-get install as well.

Creating a rootfs tarball

To create a rootfs for the cflinuxfs2 stack:

make

This will create the cflinuxfs2.tar.gz file, which is the artifact used as the rootfs in Cloud Foundry deployments.

Release pipeline

The generation and release of a new rootfs happens on the stacks CI pipeline.

  • A new stack is generated with make.

  • The generated tarball is deployed with the runtime-passed branch of BOSH cf-release.

     mv stacks/cflinuxfs2.tar.gz cf-release/blobs/rootfs/cflinuxfs2.tar.gz
 cd cf-release
 bosh -n create release --force
 bosh -n upload release
 bosh -n deploy

  • The cf-acceptance-tests of that cf-release are then run against that deployment.

     cd cf-release/src/github.com/cloudfoundry/cf-acceptance-tests
 go get github.com/tools/godep
 godep restore
 ./bin/test --nodes=4

  • Once all tests pass, the rootfs tarball can be found as a Github Release and a Docker Image.
