Docker 1.13 introduced a new version of Compose that simplifies deployment. In our last webinar, Alexei Ledenev (Cheif Researcher at Codefresh) walked us through the new features in Compose V3 developers can use for deployment. In case you missed it, we recorded it for you to view on demand. During the session, you’ll learn how to quickly create a multi-node Swarm cluster on your laptop, (without needing to install and manage additional VMs).

1. Development
Swarm Cluster
docker for Mac/Windows
docker-compose v3
docker-in-docker

3. Docker 4 Mac/Windows
• Easy installation and setup of a complete Docker
development environment
• Fast and reliable performance with native macOS
virtualization (xhyve for OS X) or native Windows Hyper V
virtualization (for Windows) running a custom minimal Linux
distro (Alpine)
• Seamless volume mounting for code and data, including file
change notifications that unlock fast edit-test cycles
• Excellent network support allows working transparently with
VPNs and proxies
• Multi-CPU Architecture Support: arm, mips, ppc64le and
even s390x (Mac only)

4. Docker Swarm Mode

5. $ docker stack deploy --compose-file docker-compose.yml myapp

6. $ docker stack deploy
vs
$ docker-compose up
• docker client has a built-in docker-
compose.yaml v3.x parser
• docker client reads deploy section to
deploy a service on swarm cluster
• docker-compose CLI tool also has a
built-in docker-compose.yaml v3.x
parser
• docker-compose CLI tool ignores
deploy section and does not deploy
on swarm cluster
• docker-compose CLI tool works
against single Docker host only
Docker Swarm
Cluster
Single Docker
Host

7. Compose v3 vs Bash

8. Compose v3 `deploy`
• mode - global | replicated
• replicas
• placement - constraints: node.id/hostname/role/labels,
engine.labels
• update_config - parallelism, delay, failure_action, monitor,
max_failure_ratio
• resources - cpu_shares, cpu_quota, cpuset, mem_limit,
memswap_limit, mem_swappiness
• restart_policy - condition, delay, max_attempts, window
• labels
