我尝试部署 docker stack,其中包括我的开发环境。但在随机情况下,我有下一个错误:

> 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 守护进程。有时它需要杀死 docker 进程和垫片。我删除旧堆栈并重新构建。有时 docker 成功完成构建,但套接字在开始阶段崩溃。

当我以常规模式启动它时,所有容器都可以正常工作,没有群或堆栈。它不能完全在 swarm 内部工作。

我已经使用下一个命令来构建:

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

在 Antergos Linux(Arch) 中运行的环境。

布局如图所示 在此处输入图像描述

使用命令创建的 Nginx 容器和 docker 网络:

>$ docker run --detach --name nginx-main --net dev-env-ext --ip 10.20.20.10 --publish 80:80 --publish 443:443 --volume /env-vol/nginx/conf:/etc/nginx:ro --volume /env-vol/nginx/www:/usr/var/www --volume /env-vol/nginx/logs:/usr/var/logs --volume /env-vol/nginx/run:/usr/var/run --volume /env-vol/ssl:/usr/var/ssl:ro nginx-webserver

套接字的问题来自源代码的错误 Python 安装和库的手动安装。看起来我安装了不兼容的版本。当我从存储库重新安装 Python 时,此问题不再出现。
