DockerCon 2019 took place in San Francisco, from April 29th to May 2nd. Open Source @ Dockercon Summit took place Thursday, May 2nd. Dockercon 2019 was a success with 5000+ participants. We are planning a recap Meetup to highlight overall announcements, new features & news from the event:, - new CLI plugins announcement (docker app, docker buildx, docker pipeline etc); - features of Docker Enterprise 3.0 ( assemble, template etc) - takeaways; useful links, demos, tips and tricks and of course all videos from all the sessions - cool stuff from the Open summit, like the powerful buildkit - Demo: Multi-arch Docker Builds Under this Meetup, we'll discuss news / new feature announcements during Dockercon and their implications for the ecosystem and end user. In addition to the DockerCon recap, we'll have the usual opportunities for networking and Q&A. We will look to answer any questions you have about Dockercon at this meetup. We invite all of our members to come -- whether you're a beginner or an experienced user of containers. Don't forget to RSVP for this event so we can make sure we have plenty of place for everyone. Save the date for Docker Timisoara Meetup on May 23th @ CoWork The Garden!

10. Docker Desktop Enterprise
• Single click to a native local Docker and certified
Kubernetes environment for fast onboarding
• Enable developer choice without compromising
security
○ Choice of IDE
○ Choice of programming language
○ Choice of app framework
○ Choice of OS
• App Designer & Templates: GUI to automatically
generate Dockerfiles and Docker Compose files of
IT ops-provided pre-configured app stacks to
compress on-boarding safely
• Pipeline: Automatically generate pre-configured
pipelines for any CI backend to jumpstart outer
loop
• Version Packs: Match desktop and server
environments to avoid “works on my machine”
friction
• Centralized Management: Maintain security and
compliance while enabling developer productivity
through centralized deployment, configuration,

11. First and only commercial Kubernetes support
for both desktops and servers
● Docker Desktop Enterprise and UCP
● Synchronized via Version Packs
● Certified K8s, commercially supported
The only product with support for Docker
Compose, Helm, Kubernetes yaml
Enhanced security and access controls
● Certificate-based authentication in addition
to LDAP/AD and SAML 2.0
● Automated compliance assessment and
reporting
Complete Day 1 and Day 2 ops for Kubernetes
● Installation, configuration, and hardened
security
● Upgrades, backup, and restore

12. Docker Applications

● “Container of containers” defines an
application that can be comprised of multiple
services
● Removes the need to manage “mountains of
YAML” and eliminates configuration overhead
Supports Docker Compose, Kubernetes
YAML, Helm Charts and more
● Implements the new open standard, CNAB,
announced by Docker and Microsoft
● Parameterized fields allow for flexible
deployment across different environments,
delivering on “code once, deploy anywhere”

13. Docker Enterprise-as-a-
Service
Managed Service

• Full-managed enterprise container platform
service
○ CI/CD infrastructure
○ Docker Trusted Registry (DTR)
○ Universal Control Plane (UCP), including
orchestration
○ Docker Engine worker nodes
• Choice

30. @mikesir87
Clean up as you go!
● Don’t wait until the end of the Dockerfile to “clean” up
● Chain RUN commands together to clean things as you go
FROM ubuntu
RUN apt-get update
RUN apt-get install -y python python-pip
RUN pip install awscli
RUN apt-get autoremove --purge -y python-pip
FROM ubuntu
RUN apt-get update &&
apt-get install -y python python-pip &&
pip install awscli &&
apt-get autoremove --purge -y python-pip &&
rm -rf /var/lib/apt/lists/*
Net change of image size from
512MB to 183MB (64% reduction)

31. @mikesir87
Keep images tight and focused
• Only install the deps/tools/packages that are necessary
• Use multi-stage builds to separate build-time and run-time
dependencies
FROM node AS build
WORKDIR /usr/src/app
COPY package.json yarn.lock .
RUN yarn install
COPY public ./public
COPY src ./src
RUN yarn build
FROM nginx:alpine
COPY nginx.conf /etc/nginx/nginx.conf
COPY --from=build /usr/src/app/build /usr/share/nginx/html
Sample multi-stage build for a React app
