ubuntu14.04のDockerのipアドレスを変更

投稿者: utsubo 投稿日: 2016-06-23 in docker

dockerはdocker0インターフェースに自動で172.17.42.1のIPアドレスを割り当てます。
これで困るのが、実際のネットワーク上にこのセグメントがある場合。
ｄｏｃｋｅｒを起動したこのサーバに、リモートからアクセスできなくなります。

デフォルトの設定

# ifconfig
docker0   Link encap:Ethernet  HWaddr 56:84:7a:fe:97:99  
          inet addr:172.17.42.1  Bcast:0.0.0.0  Mask:255.255.0.0
          UP BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

# ifconfig

docker0 Link encap:Ethernet HWaddr 56:84:7a:fe:97:99

inet addr:172.17.42.1 Bcast:0.0.0.0 Mask:255.255.0.0

UP BROADCAST MULTICAST MTU:1500 Metric:1

RX packets:0 errors:0 dropped:0 overruns:0 frame:0

TX packets:0 errors:0 dropped:0 overruns:0 carrier:0

collisions:0 txqueuelen:0

RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)

そこで、ｄｏｃｋｅｒ０のIPアドレスを変更します

修正

/etc/default/dockerファイルに追加

DOCKER_OPTS="--bip=172.66.33.0/24"

1	DOCKER_OPTS="--bip=172.66.33.0/24"

リブートします

$ sudo reboot

1	$ sudo reboot

確認

再度ログインし確認します

$ ifconfig
docker0   Link encap:Ethernet  HWaddr 56:84:7a:fe:97:99  
          inet addr:172.66.33.0  Bcast:0.0.0.0  Mask:255.255.255.0
          UP BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

$ ifconfig

ubuntu14.04のDockerをubuntuユーザで起動

投稿者: utsubo 投稿日: 2016-06-23 in docker

ubuntu14.04にDockerをインストールし、一般ユーザで動かします。

インストール

$ sudo apt-get install docker.io

1	$ sudo apt-get install docker.io

面倒になると困るのでiptablesを削除します

$ sudo iptables -F -t nat
$ sudo iptables -F

1 2	$ sudo iptables -F -t nat $ sudo iptables -F

起動

こちらを参考に

$ sudo groupadd docker   # これは不要かもしれない
$ sudo gpasswd -a ${USER} docker
$ sudo /etc/init.d/docker restart

$ sudo groupadd docker # これは不要かもしれない

$ sudo gpasswd -a ${USER} docker

$ sudo /etc/init.d/docker restart

一度ログアウトしもう一度ログインします

$ docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES

1 2	$ docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

Docker in DockerのJenkins環境をdockerで構築

投稿者: utsubo 投稿日: 2016-02-19 in docker

dockerで構築したjnekins内でdockerイメージを作成する

これができるとjenkinsでDockerイメージまで作成し、デプロイが簡単になります。

Dindイメージを使って作成してみます

docker buildのエラー

こういう時には一度キャッシュをクリーンすれば治ります
