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)

Docker Swarm Mode

by Nigel Poulton http://blog.nigelpoulton.com/docker-launches-kubernetes-killer/

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

$ 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

Compose v3 vs Bash

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
