Create a macvlan network interface and a bridge network. To access the Docker container, you’d then use your Synology NAS’s IP address and the local port ( 2. For example, if the Docker container wants to use port 80, change the Local Port to be something different, like 8080 as shown below. Change the local port so that you’re using something different.In situations like this, you have two main ways of fixing the problem: When this occurs, a port conflict will stop the container from functioning properly. There are situations where a docker container will use certain ports (80/443 for example) and the host network interface already uses those ports for something else.

To reiterate, if you want to update a file on the container, create a local file on your Synology NAS and map that file to the container’s internal file. When the container runs, the nf file on the container will be replaced with the contents of the nf file on the Synology NAS. An example of that is the nf file in the screenshot below. This next part is a little tricky – you can overwrite a specific file on the container by creating a local version of that file and selecting the exact path where that file exists on the container. The rest is simply configuration that can be created on a separate NAS or Docker installation. These are the important folders that must be backed up. If you are interested in backing up a container, the folders you mount for each container hold all of your personal data. When the container is started, the contents of the container’s /etc/pihole folder will be written to my Synology NAS’s etc-pihole folder. Those folders are inside of the docker folder and are mounted to the container’s /etc/pihole folder. Using the screenshot below, I created a folder named pi-hole and a sub-folder name etc-pihole. You can easily translate this to a Synology NAS by creating subfolders in the docker folder and mounting that folder location to the container’s folder. etc-pihole/:/etc/pihole/ as an example, etc-pihole is the local folder and /etc/pihole is the container’s folder. Under the volumes section, you can find the two volumes that can be mounted. Using Pi-Hole as an example, an example Docker Compose file is provided. Unfortunately, all documentation is different, so you will have to search through it to find the volume information. You can search that documentation to see what folders can be mounted.Īfter you navigate to the documentation, you will have to search the page to see what volumes can be mounted.

When you download an image from the registry, a little icon (shown below) will bring you to the documentation for that container. It’s important to highlight that you can’t mount any folders that you’d like. Any data that is modified on the local Synology NAS folder will write to the containers folder. When the container runs, the container’s folder location in the Mount Path below is written to the File/Folder entered on your Synology NAS. This is completed in the Volume section, where a local folder is mapped to a container folder. When creating a Docker container, the important data must be mapped to a local folder.
