kianosja/cflinuxfs3

This is dervived from the Cloud Foundry cflinuxfs3 build with some additional packages added on. Below is the original README.md.

Cloud Foundry stack: cflinuxfs3

This stack is derived from Ubuntu 18.04 (Bionic Beaver)

Dependencies

• GNU make
• Docker

Creating a rootfs tarball

To create a rootfs for the cflinuxfs3 stack:

shell
make

This will create the cflinuxfs3.tar.gz file, which is the artifact used as the rootfs in Cloud Foundry deployments.

Creating a BOSH release from the rootfs tarball

To start, clone the https://github.com/cloudfoundry/cflinuxfs3-release containing the cflinuxfs3-rootfs BOSH release:

shell
git clone git@github.com:cloudfoundry/cflinuxfs3-release.git
cd cflinuxfs3-release

Replace the old cflinuxfs3 tarball with the new tarball created above:

shell
rm -f config/blobs.yml
mkdir -p blobs/rootfs
cp <path-to-new-tarball>/cflinuxfs3.tar.gz blobs/rootfs/cflinuxfs3-new.tar.gz

Create a dev release and upload it to your BOSH deployment:

shell
bosh create release --force --with-tarball --name cflinuxfs3-rootfs
bosh upload release <generated-dev-release-tar-file>

If your Diego deployment manifest has version: latest indicated for the cflinuxfs3 release, then redeploying Diego will enable this new rootfs.

Release pipeline

The generation and release of a new rootfs happens on the cflinuxfs3 CI pipeline.

• A new stack is generated with make.

• A dev BOSH release of that new stack is generated and deployed to a BOSH Lite deployment.

• CF and Diego are deployed to that BOSH Lite. The https://github.com/cloudfoundry/cf-acceptance-tests are then run against the deployment.

• Once all tests pass and the product manager ships the release, the rootfs tarball can be found as a https://github.com/cloudfoundry/cflinuxfs3/releases, https://registry.hub.docker.com/u/cloudfoundry/cflinuxfs3/, and as a https://github.com/cloudfoundry/cflinuxfs3-release.
