How to use Bind-Mounting

Since the Docker engine is getting better the performance losses especially on Macs are not as big as they used to be when using bind-mounting in projects such as Symfony or Shopware.

Some of you know, that we like the SFTP way, as it's the best controllable and platform independent way to handle the project and file permissions.
But we get often asked on how to work with dockware and bind-mounting, which is indeed possible.
Bind-Mounting is a plain Docker feature has nothing to do with dockware itself.
Thus all related things, including issues such as file permission problems do not have to do anything with dockware. Please keep that in mind when searching for answers to problems.
Let's get started with our bind-mount setup.
​
1. Prepare a clean project 
An easy starting point for that is to use our "dev" example on Github. https://github.com/dockware/examples/tree/master/bind-mount​
Create a folder like src on your host (maybe in the same directory as your docker-compose...)
2. First Start with Dockware files (no bind-mount)
This step has only to be done once per project! 
And only if you use dockware:dev which provides already an installed shopware version. If you wan't to use your own project/installation you can go to step 3.
For Linux users only! (To be executed on your HOST, not docker)
Make sure your host user is in the docker and www-data groups (check with groups command)
Restart your pc to make sure the permissions get granted
This steps only required  if you wan't to use the shopware version provided by your dockware:dev container. Not If you wan't to use your own project/installation.
Make sure your host src directory is empty 
Make sure the volumes are commented out in the docker-compose.yml 
Start the container with docker-compose up -d
Initially copy the dockware files to your host with: docker cp shop:/var/www/html/. ./src
Move the content around (cd src && mv html/* . && mv html/.env . && rmdir html && cd .. )
3. Set Permissions
For Linux users only!  (To be executed on your HOST, not docker)
Set permissions (chgrp -R www-data src ) - possible that you need sudo for this
Set write permissions for cache/log (chmod a+w src/var/* )
4. Enable Bind-Mounting
Now you have to modify your docker-compose.yml and enable the bind-mounting.
You can find a full docker-compose example here https://github.com/dockware/examples/tree/master/bind-mount​
docker-compose.yml
...
​
volumes:
      - "./src:/var/www/html"
      
....
4. Restart the container
Now restart your container and bind-mounting including all your Shopware files is ready to use.
You can now change files on your host, and it will be immediately shown without uploading it using SFTP
Keep in mind, when you upload with SFTP while having an active bind-mount, that will remove the files! Do not mix both ways!
