はじめに
ちょこちょこDockerを触っているのですがネットワーク設定まわりについての自分用メモ
以下の書籍を参考にしています。

- やりたいこと
- Dockerコンテナのネットワークのプチ基礎
- ネットワークを作成する
- 複数のContainer同士で繋いでみる
- ネットワークを削除する
1. やりたいこと
やりたい事は以下です
- dockerのネットワークを作成する
- 複数のcontainerを作成した同一ネットワークに接続
- container同士でアクセスする
2. Dockerコンテナのネットワークのプチ基礎
Dockerはデフォルトでbridge/host/noneの3つのネットワークを作成します
$ docker network ls NETWORK ID NAME DRIVER SCOPE b917ccb08e42 bridge bridge local 45c4f50ef8dd host host local e1785a610499 none null local
明示的にネットワークを指定せずにDockerコンテナを起動すると、
デフォルトのbridgeネットワークにDockerコンテナを起動します。
# 適当に立ち上げてみる
$ docker container run -itd --name=sample ubuntu:latest
# .NetworkSettings.Networks}}を確認するとbridgeになっている
$ docker container inspect sample --format="{{json .NetworkSettings.Networks}}"
{"bridge":{"IPAMConfig":null,"Links":null,"Aliases":null,"NetworkID":"b917ccb08e42a549dd85213c3e705a3ab03295656d760340ab04781ffe8f98da","EndpointID":"9fd096a5ff16be1542c1154baeebce92bc3b5abf6723f9d05ecbc5c36a6ff7c9","Gateway":"172.17.0.1","IPAddress":"172.17.0.2","IPPrefixLen":16,"IPv6Gateway":"","GlobalIPv6Address":"","GlobalIPv6PrefixLen":0,"MacAddress":"02:42:ac:11:00:02","DriverOpts":null}}

3. ネットワークを作成する
ネットワークの作成は以下のコマンドで行います
docker network create [オプション] ネットワーク
オプションは以下が指定可能です。
| オプション | 説明 |
|---|---|
| --driver, d | ネットワークブリッジまたはオーバーレイ（デフォルトはbridge） |
| --ip-range | コンテナに割り当てるIPアドレスのレンジを指定 |
| --subnet | サブネットをCIDR形式で指定 |
| --ipv6 | IPv6ネットワークを有効にするかどうか（true/false） |
| -label | ネットワークに設定するラベル |
今回は--driver=bridgeでweb-networkというネットワークを作成してみます。
$ docker network create --driver=bridge web-network fe7f79487aa87cf03e03c857fc0013d3b85656fad9fb4417f9abfb2402f17c60 # 作成したネットワークを確認 $ docker network ls NETWORK ID NAME DRIVER SCOPE b917ccb08e42 bridge bridge local 45c4f50ef8dd host host local e1785a610499 none null local fe7f79487aa8 web-network bridge local $ docker network ls --filter driver=bridge NETWORK ID NAME DRIVER SCOPE b917ccb08e42 bridge bridge local fe7f79487aa8 web-network bridge local
4. 複数のContainer同士で繋いでみる
ネットワークへの接続
ネットワークへの接続は
docker networkで接続する方法と、
docker run時に接続する方法があります。
docker networkでcontainerをネットワークに接続するには以下のコマンドを使います
docker network connect [オプション] ネットワーク名 コンテナ名
docker runで接続するには以下のコマンドを使います
docker container run オプション --name=コンテナ名 --net=ネットワーク名 コンテナイメージ
今回はdocker runのほうで試します。
1つめのcontainer
バックグラウンドでwebappという名前のcontainerを
ネットワークweb-networkにつないで立ち上げます。
また、ポートはホストOS:8001からcontainerの80につなげます。
$ docker container run -itd -p 8001:80 --name=webapp --net=web-network nginx 8296c047ebf6e8f7d3755dec287903e5d7afee93cf96a47c7ef4b1c3ef04ded7
ブラウザでアクセスしてみる
ブラウザで確認すると当然こんな感じ
2つめのcontainer
webfrontという名前のcontainerを
ネットワークweb-networkにつないで立ち上げてbashで起動。
また、container1 -> container2から繋いでみる際は、curlでポート80で繋ぎます。
$ docker container run -it --name=webfront --net=web-network centos /bin/bash
# 1つめのcontainerにcurlしてみる
# nginxの結果が帰ってくる
[root@c1170773ec3c /]# curl webapp:80

うまくいきました！
inspectで確認
containerをinspectで確認してみると、
.NetworkSettings.Networksにてweb-networkに繋がっている事が確認できます。
$ docker container inspect webfront webapp

5. ネットワークを削除する
ネットワークを削除するには以下のコマンドです
docker network rm [オプション] ネットワーク名
containerが起動している状態だとエラーが出るのでstopしてから行います
# ネットワークに接続しているcontainerが起動しいるとエラー $ docker network rm web-network Error response from daemon: network web-network id fe7f79487aa87cf03e03c857fc0013d3b85656fad9fb4417f9abfb2402f17c60 has active endpoints # stopする $ docker container ls -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES e312f6dfd765 centos "/bin/bash" 34 minutes ago Up 30 minutes webfront 8296c047ebf6 nginx "nginx -g 'daemon of…" 38 minutes ago Up 38 minutes 0.0.0.0:8001->80/tcp webapp $ docker container stop e312f6dfd765 8296c047ebf6 e312f6dfd765 8296c047ebf6 # stop後だと消せる $ docker network rm web-network web-network
