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

Question

I recently started with docker and I have been following this steps to make a cluster with laradock https://github.com/jarnovanleeuwen/laravel-dock

first I create with docker-machine 2 nodes, one manager and the other a worker then with this comand I set the manager node as the leader

docker swarm init --advertise-addr 192.168.99.100

I add the other node as a worker with

docker swarm join

After I access the manager node with docker-machine ssh manager and create a service

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

I leave the virtual machine with exit and cd into the folder laravel-dock, then I up the containers to create the images with

./dock up

then I set it down

./dock down

I build the image with

./dock build

Then i push it into the service I created with

./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

With this I try to deploy the stack with

./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
Warning: Permanently added '192.168.99.100' (ECDSA) to the list of known hosts.

OK
docker@192.168.99.100's password: 
./dock-swarm: line 4: .env: No such file or directory

it request the password for the machine that is "tcuser" and come with this error ".env: No such file or directory", so I manually copy the.env to this folder created in the manager node with

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

I try to deploy again and have this error

sudo ./dock deploy

And at this point I have stuck with this error, am I doing something wrong in this steps? also here is the configurations

Answer 1

I spent an hour on this bug. In my case problem was caused by missing docker-compose on remote server.
