使用 laradock 使用 laravel 和 docker swarm 创建集群的问题

Question

我最近开始使用 docker，我一直在按照这些步骤使用 laradock 创建一个集群 https://github.com/jarnovanleeuwen/laravel-dock

首先我使用 docker-machine 2 个节点创建一个管理器，另一个是工人 然后使用此命令将管理器节点设置为领导者

docker swarm init --advertise-addr 192.168.99.100

我将另一个节点添加为工作人员

docker swarm join

在我使用 docker-machine ssh manager 访问管理器节点并创建服务后

docker service create --name registry --publish published=5000,target=5000 registry:2

我用 exit 和 cd 离开虚拟机到文件夹 laravel-dock，然后我打开容器来创建镜像

./dock up

然后我把它放下

./dock down

我用

构建图像

./dock build

然后我将它推送到我创建的服务中

./dock push

The push refers to repository [192.168.99.100:5000/registry]
Get https://192.168.99.100:5000/v2/: http: server gave HTTP response to HTTPS client

有了这个我尝试部署堆栈

./dock deploy

Are you sure you want to deploy [192.168.99.100:5000/registry:web] to [docker@192.168.99.100]? (y/N) y

Uploading deployment configuration...The authenticity of host '192.168.99.100 (192.168.99.100)' can't be established.
ECDSA key fingerprint is SHA256:r1F+7kuet+grlysNruBECAmYpRVVlvORYhAR4ipNFco.
Are you sure you want to continue connecting (yes/no)? yes

./dock-swarm: line 4: .env: No such file or directory

它请求“tcuser”机器的密码并出现此错误“.env：没有这样的文件或目录”，所以我手动将 .env 复制到在管理器节点中创建的这个文件夹中

docker-machine scp -r .env manager:/home/docker/laraveldock

我尝试再次部署并出现此错误

sudo ./dock deploy

我在这个错误上花了一个小时。在我的情况下，问题是由于远程服务器上缺少 docker-compose 引起的。
