Docker complains that bind source path doesn't exist, but it DOES

Question

I'm trying to start a mysql container with a host directory mounted. I'm running a single-node swarm in Docker for AWS. But I can't mount a directory...

This is the section of the docker-compose file I'm using:

mysql:
    image: mysql-custom
    volumes:
        - /mysql:/var/lib/mysql
    ports:
        - "3307:3306"

And this is the launch command I'm trying:

docker stack deploy --compose-file docker-compose.yml stack12

When I launch however, docker swarm rejects the image, saying "invalid mount config for type \"bind\": bind source path does not exist". However, /mysql is a valid directory, I can cd to it and everything, so why is docker saying it does not exist?

@FrankNoel I'm trying to mount a folder, not use a docker volume — Scott Shorkey, Jul 07 '17 at 15:53
Please edit the question to add: Docker version, host OS, how Docker was installed, and what commands are producing the error. — Andy Shinn, Jul 07 '17 at 16:06
You're talking about swarm: is the folder available on any node of your cluster? Or are-you using affinity constraint? — zigarn, Jul 07 '17 at 16:06
@zigarn it's a single node cluster and the folder is available on that node — Scott Shorkey, Jul 07 '17 at 17:17
ERROR: for jenkinsdocker_master_1 Cannot create container for service master: invalid mount config for type "bind": bind source path does not exist ... How could someone possibly not display what path Compose expects to see is beyond me. — Christophe, Mar 02 '18 at 10:33

According to what you are trying, mysql needs to be in root directory. You can try this

mysql:
    image: mysql-custom
    volumes:
        - ./mysql:/var/lib/mysql
    ports:
        - "3307:3306"

Notice the . before mysql. And directory structure for this can be:

.
|__docker-compose.yml
|__mysql
   |__(Your content)
   |__(some more files)

Nope, adding the "." did not change anything. – Scott Shorkey Jul 10 '17 at 14:02
Can you provide the directory structure! I still have doubts regarding the exact location of `mysql` directory which this compose file is trying to mount – Ayushya Jul 10 '17 at 17:36

I experienced the same issue due to permissions. I recommend you make a test where you grant 777 to /mysql to see if it works -> then tweak the permissions to match your security requirements
