What is wrong with below code? i have 2 services wordpress &mysql and i want to persist data in 2 node swarm cluster when i deploy through docker stack deploy. I’m using bind mounts as named mounts are not persisting data. I have also restricted wordpress to manager and sql to worker so they create bind mounts in their own nodes and thus persist data. or am i completely wrong? Kindly help. While stack deployment i get an error as “invalid mount config for type…”
