复制服务未更新 [英] Replicated services not updating

问题描述

我有一项服务，该服务已配置为具有3个副本（在3个节点的群集中）。当需要将服务更新到新版本时，我运行以下命令：

I have a service which I've configured to have 3 replicas (in a swarm of 3 nodes). When it comes time to update the service to a new version, I run this:

docker stack deploy -c docker-compose.yml authentication

我还尝试使用以下命令强制进行更新：

I've also tried to force an update using:

 docker service update --force authentication_authentication

一个实例将被更新，其他实例将保持相同版本。上面的更新命令永远挂在这里：

One instance will get updated, the others will remain on the same version. The update command above hangs here forever:

overall progress: 1 out of 3 tasks 
1/3: running   [==================================================>] 
2/3:   
3/3:   

在docker的systemd日志，我看到以下条目：

In the systemd logs for docker, I see these entries:

Sep 10 10:24:28 docker01 dockerd[1478]: time="2018-09-10T10:24:28.910584651-04:00" level=warning msg="rmServiceBinding 489e7143d27eaa4e4210b080f77b60018a033b29a291599d63def87fb0bed903 possible transient state ok:false entries:0 set:false "

如何获取这些服务进行更新？

How can I get these services to update?

其他详细信息：

• Docker 18.06.0-ce


• Ubuntu 16.04.5大TS

docker-compose.yml：

docker-compose.yml:

version: "3.1"

services:
   authentication:
    image: "<private registry>/authentication:1.0.11"
    ports:
      - 8008:8008
    deploy:
      mode: replicated
      replicas: 3
      placement:
        constraints:
          - node.platform.os==linux

在docker config文件中打开调试功能，现在在日志中反复看到：

Turned debug on in the docker config file and am now seeing this repeatedly in the log:
