复制服务未更新
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

在docker的systemd日志,我看到以下条目:
In the systemd logs for docker, I see these entries:

如何获取这些服务进行更新?

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:
