Distribute Development Env by docker-composeKengo TODA

whoami

Java, JavaScript R&D

Build tools, CI

OSS web app with distributed dev environment

Merit of Docker

Small, Clean, Quick, Portable, Reproducible

Good for delivery

to cloud, data centre and developer’s machine new!

Case: provide dev environment for your contributors

Web Service needs:

Middleware

Initial data in datastore

Legacy ways to provide dev environment

README.txt

Virtual box, VMware

Vagrant (https://www.vagrantup.com/)

Problems of legacy ways

Human don’t read document

VM is BIG & SLOW

Middleware conflict

Docker is

Process to make VM is more clear and documented

Quick bootstrap

Layer is small enough to distribute

Reproducible even on different OS

But how to keep

'one service in each container’ policy?

docker-compose

Build, run and link containers by one command

Treat set of containers like: Application server, Web server, Datastore server, Selenium client, build tools…

docker-compose.yml

docker-compose up$ docker-compose up Creating consul_1... Creating registrator... Creating storage_1... Creating front_1... Creating nginx_1... Attaching to consul_1, registrator, storage_1, front_1, nginx_1 consul_1 | ==> Starting raft data migration...

Conclusion

Docker is good for delivery, even to developers!
