Building a secure software
supply chain
Leveraging Tanzu Build Service

Building secure
Docker images is hard

Keep Docker images
secure is even harder

Case study:
OpenSSL CVE-2016-6304

Base OS image
FROM alpine
RUN apk add --update openssl
...
App
FROM nodejs
COPY myapp .
RUN npm install
...
NodeJS
FROM baseimage
RUN apt-get install nodejs
...
Built with a custom base image
Typical NodeJS app: everything works just fine

Base OS image
NodeJS
App
FROM baseimage
RUN apt-get install nodejs

FROM alpine
RUN apk add --update openssl
...
FROM nodejs
COPY myapp .
RUN npm install

A new critical CVE is made public
Until that day...

How long does it take to fix all these containers?
What if you had to update 200+ containers at once?

Individually managed
Dockerfiles: done wrong

CentOS
App #3
Oﬃcial NodeJS

ETA to mitigation:
months, years…?

We can do better

Introducing Cloud Native Buildpacks
An API for creating pluggable, modular tools that
translate source code into OCI images
Goals
❏ Portability via the OCI standard
❏ Greater modularity
❏ Faster builds
❏ Reproducible image builds
❏ Unprivileged containers
❏ Widely adopted standard
An easy way to build Docker images

They use Cloud Native Buildpacks

What happens when you build a container with buildpacks
detect
restore
analyze
build
export
cache
Lifecycle

detect
restore
analyze
build
export
cache
➔ Tests groups of buildpacks against source, in order
(via each buildpack’s detect binary)
➔ First group that passes is selected
NPM CNBNode CNB
Yarn CNBNode CNBsrc/
package.json
yarn.lock
...
Lifecycle: Detect

detect
restore
analyze
build
export
cache
analyze
➔ metadata about OCI layers generated during a
previous build are made available to buildpacks
Lifecycle: Restore & Analyze

detect
restore
analyze
build
export
cache
➔ For previously-selected group, executes each
buildpack’s build executable in order
src/
package.json
yarn.lock
...
Lifecycle: Build

detect
restore
analyze
build
export
cache
➔ Assembles ﬁnal layers into image
➔ Combines information from analyze phase to ensure
only changed layers are updated
cache
Lifecycle: Export & Cache

Build Service
powered by Tanzu buildpacks

Declarative Conﬁguration Model:
➔ Tell Build Service what you want your app to
look like by creating an image conﬁguration,
and Build Service will build against it and keep
it up to date when new dependencies are
available.
