daoli 使用方法_flask

運行執行個體：

主節點：

1.1. 建立網路

# docker -H :3380 network create --subnet=11.1.0.0/24 --gateway=11.1.0.1 --driver=daolinet dnet11

1.2. 啟動容器

# docker -H :3380 run -ti -d --net=dnet11 --name test11 centos

# docker -H :3380 run -ti -d --net=dnet12 --name test12 centos

（這時在主節點找不到相應的容器，你可以在子節點看到，在子節點運行# docker inspect test11。）

1.3. 測試容器網路

docker -H :3380 attach test11

[root@9dae2dc3a17e /]# ping 11.1.0.3

PING 11.1.0.3 (11.1.0.3) 56(84) bytes of data.
64 bytes from 11.1.0.3: icmp_seq=1 ttl=64 time=11.9 ms

（通過主節點進入 test11容器，可以ping通test12。）

同樣的方法建立test13,test14在192.168.0.段，進入 test11容器ping 192.168.0.x的IP，是可以ping通的。

查看子節點：

# ip r

11.1.0.0/24 dev tap018e5ccafed  proto kernel  scope link  src 11.1.0.1 

yum -y install net-tools iproute traceroute

# ip netns add ns11

# ip link set tap018e5ccafed netns ns11

目前通過命名空間可以限制容器不同IP段的連通性。

實際的隔離實現和文檔還是有出入的，這同樣說明官方的文檔和代碼是到期的。

你會發現資訊的添加和顯示是沒有問題，但是功能都是停用。

當然也有可用的功能，比如：

遷移容器

# ./daolictl container move --node NWMG:DGVA:JZBE:WPCL:K24H:U656:ZVZC:NPYE:CXWW:JHLR:XZY5:RYYH testweb
8085edb907b80d4c283023a24a23da038b3c1eb434fa425be150b93c57c5956b 

確實IP等資訊沒有變，遷移到了新的節點上，產生了新的容器ID

# ./daolictl container shownet testweb
