docker stack rm 后跟 deploy 失败并在连续构建上运行

Question

Jenkins 构建部分中的 Bash 脚本

#!/bin/sh

docker build -t smstake:latest .

#Push to the private  repository applying the proper tags for the image
docker tag smstake:latest reg01.dev.01cloud.com:5000/smstake:1.0.1
docker push reg01.dev.01cloud.com:5000/smstake:1.0.1

docker stack rm smstake
docker stack deploy -c docker-compose.yml smstake

1. 我在这里创建一个 docker 映像
2. 为其添加适当的标签以推送到私有存储库
3. 如果存在堆栈，则移除堆栈而不是再次部署它。

问题是它在第一次构建中失败，并出现了一些网络问题，如下所示。如果再次构建，它将在另一个构建上成功运行。我该如何解决这个问题。

我得到的错误：

Removing service smstake_app
Removing service smstake_db
Removing service smstake_phpmyadmin
Removing network smstake_smstake
Creating service smstake_app
failed to create service smstake_app: Error response from daemon: network smstake_smstake not found
Build step 'Execute shell' marked build as failure
Finished: FAILURE

我们可以看到它在删除服务和创建服务期间 它的投掷网络未发现问题。

这是我的 docker-compose.yml

问题是docker stack rm smstake中没有立即删除网络，而是在此命令启动后docker stack deploy -c docker-compose.yml smstake。

您可以等待网络真正被移除，然后再次部署堆栈，如下所示：

docker stack rm smstake
while [ $(docker network ls | grep smstake_smstake |  wc -c) -ne 0 ] ; do sleep 1 ; done
docker stack deploy -c docker-compose.yml smstake

只要网络 smstake_smstake 仍然存在，while 就会执行。
