docker上でredmineを動かす のバックアップ(No.1)

概要

Debian 上に Docker を入れ、その上で Redmine を動かして、いろいろ便利に使いたい。

Docker も Redmine も素人なのでだましだましです。

Docker のインストール

独立した Linux 環境を1つのプロセスとして立ち上げられるコンテナ実行環境。

Debian 用のインストラクション通りにすれば簡単だった
https://docs.docker.com/install/linux/docker-ce/debian/

LANG:console
$ uname -r                      # >= 3.2 でなければならないらしい
 3.16.0-4-amd64
$ sudo apt-get update           # 以下、docker 配布元を apt-source に入れる
$ sudo apt-get install apt-transport-https ca-certificates curl gnupg2 software-properties-common
$ curl -fsSL https://download.docker.com/linux/debian/gpg | sudo apt-key add -
 OK
$ sudo apt-key fingerprint 0EBFCD88 | grep -4 0EBFCD88 # should have finger print 9DC8 5822 9FC7 DD38 854A E2D8 8D81 803C 0EBF CD88

$ lsb_release -cs       # jessie の文字を得る
 jessie
$ sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/debian $(lsb_release -cs) stable"
$ sudo apt-get update           # 配布元からの情報を元に最新の docker-ce をインストール
$ sudo apt-get install docker-ce
 以下の追加パッケージがインストールされます:
   aufs-tools cgroupfs-mount mountall pigz plymouth
 提案パッケージ:
   desktop-base plymouth-themes
 以下のパッケージが新たにインストールされます:
   aufs-tools cgroupfs-mount docker-ce mountall pigz plymouth
 アップグレード: 0 個、新規インストール: 6 個、削除: 0 個、保留: 9 個。
 34.2 MB 中 33.8 MB のアーカイブを取得する必要があります。
 この操作後に追加で 186 MB のディスク容量が消費されます。

 Hello from Docker!
 This message shows that your installation appears to be working correctly.
 
 To generate this message, Docker took the following steps:
  1. The Docker client contacted the Docker daemon.
  2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
     (amd64)
  3. The Docker daemon created a new container from that image which runs the
     executable that produces the output you are currently reading.
  4. The Docker daemon streamed that output to the Docker client, which sent it
     to your terminal.
 
 To try something more ambitious, you can run an Ubuntu container with:
  $ docker run -it ubuntu bash

docker-composer のインストール

.yml ファイルにまとめた Docker コンテナの起動方法を元にプロセスを起動するためのツール。

https://docs.docker.com/compose/install/ の Linux ページから

LANG:console
$ sudo curl -L https://github.com/docker/compose/releases/download/1.21.0/docker-compose-$(uname -s)-$(uname -m) -o /usr/local/bin/docker-compose
$ sudo chmod +x /usr/local/bin/docker-compose
$ docker-compose --version
 docker-compose version 1.21.0, build 5920eb0

これで http://localhost:10083 へ繋ぐと Redmine の初期ページを確認できる。
