碼頭集裝箱UUID

Question

顯然，Docker容器共享相同的UUID。如何爲同一個碼頭主機上的每個容器設置不同的值？

我運行一個程序，領事，這顯然與具有相同UUID泊塢窗容器作爲問題引發此錯誤：

root@redis-2:/usr/local/bin# consul agent -config-dir /etc/consul.d/ -bind 172.17.0.3 & 
[1] 428 
root@kkbox-test-redis-2:/usr/local/bin# ==> WARNING: LAN keyring exists but -encrypt given, using keyring 
==> Starting Consul agent... 
==> Joining cluster... 
==> 3 error(s) occurred: 

* Failed to join 10.24.5.251: Member 'kkbox-test-redis-1' has conflicting node ID 'ec2484ee-2960-1781-6d95-3bd994e5f3bf' with this agent's ID 
* Failed to join 10.24.5.252: Member 'kkbox-test-redis-1' has conflicting node ID 'ec2484ee-2960-1781-6d95-3bd994e5f3bf' with this agent's ID

有沒有辦法在這裏每個容器更新UUID？：

/proc/sys/kernel/random/boot_id 

Answer 1

通行證-disable-host-node-id到consul agent ...，和領事將在啓動時生成一個隨機的節點ID（而不是從例如/proc/sys/kernel/random/boot_id生成它）。

像這樣：

consul agent -disable-host-node-id -config-dir /etc/consul.d/ -bind 172.17.0.3 & 

或者，你總是可以生成節點ID自己，並通過-node-id標誌傳遞。
