CouchbaseをDockerにインストール

Couchbase NoSQL Docker

CouchbaseはDocument型NoSQL。
Couchbase 2.5をDockerで構築してみる。
Docker環境については下記を参照。

■Dockerfile

FROM centos

WORKDIR /tmp

RUN echo 'exclude=kernel*' >> /etc/yum.conf
RUN echo 'proxy=http://[proxy_FQDN]:[port]' >> /etc/yum.conf
RUN echo 'proxy_username=[username]' >> /etc/yum.conf
RUN echo 'proxy_password=[password]' >> /etc/yum.conf

RUN yum install -y pkgconfig
ENV http_proxy http://[username]:[password]@[proxy_FQDN]:[port]
ENV https_proxy https://[username]:[password]@[proxy_FQDN]:[port]
RUN wget http://packages.couchbase.com/releases/2.5.1/couchbase-server-enterprise_2.5.1_x86_64.rpm
RUN rpm --install couchbase-server-enterprise_2.5.1_x86_64.rpm
EXPOSE 4369 8091 8092 11209 11211 21100 21299

EXPOSEで指定したポート設定は適当。(ポートの範囲指定ってどうするんだ。。。?)

■Couchbase Serverが使用するポート

Port Description Node to Node Node to Client Cluster Administration XDCR
8091 Web Administration Port Yes Yes Yes Yes
8092 Couchbase API Port Yes Yes No Yes
11209 Internal Cluster Port Yes No No No
11210 Internal Cluster Port Yes Yes No No
11211 Client interface (proxy) Yes Yes No No
4369 Erlang Port Mapper ( epmd ) Yes No No No
21100 to 21199 (inclusive) Node data exchange Yes No No No

参考:http://docs.couchbase.com/couchbase-manual-2.0/

docker buildしてimageを作成。

起動。

なんかExit 127だし、メモリ不足で起動失敗してるっぽい。
インタラクティブに起動してcouchbase-server startして、ブラウザから8091ポートアクセスしたら見えた。
Dockerfileとしてはたぶん大丈夫かな。
