Well, this issue was my pain in the ass until I fully understood what was going on with nginx-proxy container and docker-compose v2.<\/p>\n
When you have docker-compose.yml<\/b> with separate frontend network you need to connect this network to nginx-proxy container in order to work. Obviously, there is no frontend network<\/b> until you up your containers for the first time! network will be created, but nginx-proxy will not be attached to it! So you need to shut down your app containers, do<\/p>\n and then to fire your containers up again! But wait, you need to restart nginx-proxy container to connect to this new network!<\/p>\n As you can see this process can not be single step deployment solution on CoreOS, but now you know why and how to fix this.<\/p>\n",
