python - docker 容器在停止或删除后启动新容器

Question

我关注了“开始”tutorial在官方 docker 网站上，一切顺利，直到我尝试删除容器。每次运行的时候

docker rm -f [container_id]

或

docker stop -f [container_id]

具有该 ID 的初始容器停止或删除，但新容器出现并运行。我尝试使用以下命令更新容器:

docker update --restart=no $(docker ps -aq)

然而这并没有帮助。

这里'docker info'命令结果:

Answer 1

这可能是因为您正在运行一个 docker swarm 堆栈，它对运行的节点数量进行负载平衡。尝试通过以下方式取下堆栈:

docker stack rm getstartedlab

正如他们在网站上所建议的那样。
