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

我在这里创建一个码头图像
向其添加适当的标签以推送到私人存储库
删除堆栈（如果存在），而不是再次部署它。

问题是它在第一次构建时失败，并且发布了一些网络问题。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

我们可以看到它在服务创建过程中删除服务投掷网络没有找到问题。

这是我的docker-compose.yml

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

您可以等待网络真正删除，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while仍然存在，smstake_smstake就会执行。

docker stack rm后跟部署失败并在连续构建上运行
