Use docker-compose (v3), docker-in-docker and docker for Mac/Win to quickly run a small swarm cluster for development

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
Single Docker

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
