i am trying to deploy a stack to my docker swarm but it does not work. i call the command
sudo docker stack deploy -c docker-compose.yml server-test
but it gives me the error
unsupported Compose file version: 2
but when i run
docker-compose up, it works fine. i then check the
docker-compose --version which gives me:
docker-compose version 1.21.2, build a133471
this is the latest version as of writing this. i'm fairly new to docker so any guidance on this is appreciated.
my docker-compose.yml file is as follows:
version: '2' services: caddy: build: . ports: - "80:80" - "443:443" portainer: image: portainer/portainer:latest ports: - "9000:9000" volumes: - "/var/run/docker.sock:/var/run/docker.sock"
