堆叠后Docker套接字崩溃 [英] Docker socket crash after stack up

问题描述

我试图部署包含我的开发环境的Docker堆栈.但是在随机情况下，我会遇到下一个错误:

I trying to deploy docker stack, that includes my development environment. But in random cases I have next error:

> failed to create service < service_name >: Cannot connect to the
> Docker daemon at unix:///var/run/docker.sock. Is the docker daemon
> running?

接下来，我重新启动docker daemon.有时，它需要杀死docker进程和垫片.我删除旧堆栈，然后重新构建.有时docker成功完成构建，但是套接字在开始阶段崩溃.

Next I restart docker daemon. Sometimes it requires to kill docker processes and shims. I deleting old stack and build again. Some times docker successfully finishes build, but socket crashes on the starting stage.

在常规模式下启动所有容器时，所有容器都可以正常工作，而不会出现群集或堆栈.不能完全在群内工作.

Also all containers work properly when I starting it in regular mode, without swarm or stack. It is not work exactly inside swarm.

我已使用下一条命令进行构建:

I have used next command to build:

> $ docker stack deploy dev-env-stc -c docker-compose.yml

环境在Antergos Linux(Arch)中运行.

Environment run in Antergos Linux(Arch).

布局如图所示

使用以下命令创建的Nginx容器和Docker网络:

推荐答案

套接字的问题来自源代码错误的Python安装和libs的手动安装.看起来我已经安装了不兼容的版本.当我从存储库中重新安装Python时，此问题不再出现.

Problem with socket was from wrong Python installation from sources and manual installation of libs. Looks like I have installed incompatible versions. When I have reinstalled Python from repository this problem wasn't appear again.

但是我已经得出结论，在开发环境中使用Docker Stack并不是一个明智的选择，出于这个原因，最好使用Docker Compose.因此，应将Docker Stack用于部署配置(例如Docker Swarm或Kubernetes或其他云环境的部署).

But I has concluded that using Docker Stack in development environment is not good decision, better to use Docker Compose for this reasons. So Docker Stack should be used for deployment configurations(like deploy of Docker Swarm or to the Kubernetes or to another cloud environments).
