Developing Environment with docker-compose & alpine 2017
About this article
This article is renewal version of Docker Compose + alpine으로 서버 세트 구축 1 .
I have to work with Chinese people. I'm not good at English and I don't know Chinese at all. So it's just challenge for me.
If you find any mistakes, not only language but also contents, please feel free to comment me.

Setup VPS as docker host and build servers below
VPS
I use ConoHa VPS service by GMO Korea. htp : // 이것은. jp/엔
ConoHa charges even if instance is down but it's still cheap(Mem1GB 900JPY/month). It's not famous in other country. There're not many informations in English. If you are familiar to other VPS, you shoulduse
change keymap of VM
If I had a time I wanna use AWS. But infra is not my main task. I just wanna reduce study time to acquire more study time for programming environment.
Change OS keymap
echo loadkeys us >> .bashrc
Update packages
apt-get update && apt-get upgradeInstall your locale files (ex: Korean)apt-get install language-pack-ja-base
SSH public key
Add your key to ~/.ssh/authorized_keysTry to login without password.
Install docker-compose
curl -L https://github.com/docker/compose/releases/download/1.12.0/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose
dns

Just install bind and mount config files from host's ./dns/bind directory.
dns/bind/named.confoptions {
directory "/var/bind";
allow-transfer {
none;
};
pid-file "/var/run/named/named.pid";

OK, this container is up as 172.17.0.2.
Check dns works well but alpine's nslookup has bug.
htps : // 부 gs. 삐 sy 보 x. 네 t/쇼 w_부g. c기? 예d=675
Nslookup ignored second argument. So I check from host using this container's dns.

RUN apk --update add nginx && rm -rf /var/cache/apk/*
RUN chmod 755 /var/lib/nginx /var/lib/nginx/tmp
CMD ["nginx", "-g", "daemon off;"]
Alpine linux set permission 700 of/var/lib/nginx as default. When I use reverse proxy with more than 4Kb file, I couldn't work well. The error is below:
open() "/var/lib/nginx/tmp/proxy/1/00/0000000001" failed (13: Permission denied) while reading upstream, client:
That's why chmod 755 ... is needed.
