As of May 2023 support for Ubuntu Bionic has ended, and as a result, no
further releases of the cflinuxfs3 stack will be published. Instead, please
use the Ubuntu Jammy-based stack available at
cloudfoundry/cflinuxfs4, which
will be kept up-to-date and released in the same fashion as cflinuxfs3.
This stack is derived from Ubuntu 18.04 (Bionic Beaver)
- GNU make
- Docker
To create a rootfs for the cflinuxfs3 stack:
makeThis will create the cflinuxfs3.tar.gz file, which is the artifact used as the rootfs in Cloud Foundry deployments.
To start, clone the repository containing the cflinuxfs3-rootfs BOSH release:
git clone git@github.com:cloudfoundry/cflinuxfs3-release.git
cd cflinuxfs3-releaseReplace the old cflinuxfs3 tarball with the new tarball created above:
rm -f config/blobs.yml
mkdir -p blobs/rootfs
cp <path-to-new-tarball>/cflinuxfs3.tar.gz blobs/rootfs/cflinuxfs3-new.tar.gzCreate a dev release and upload it to your BOSH deployment:
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.
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 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 Github Release, Docker Image, and as a BOSH release.
