portainer/portainer-ceThe table below lists all of the variables we used to implement Portainer.
| Parameter | Function |
|---|---|
| -v /var/run/docker.sock | sock is a Unix socket that enables the Docker server-side daemon, dockerd, to communicate with its command-line interface via a REST API |
| -v /volume1/docker/portainer:/data | Path to save data / configuration of portainer |
| -e UMASK_SET=022 | Always restart the container regardless of the exit status |
| --restart=always | EXTRA OPTIONAL: This changes the internal port of deemix. DON'T CHANGE THIS IF YOU DONT KNOW WHY YOU WOULD DO IT |
| portainer/portainer-ce | The name of the image from dockerhub |
| -p 8000:8000 -p 9000:9000 | Through 8000 port, the Edge Agent can poll the Portainer instance 9000 is for the GUI |
Go to http://YOURSERVERIP:9000 to view the web interface.
Trought SSH
Please see the post on how to access ssh if you want to use it instead of the graphical way.
- How to connect to your Synology via ssh
- After you've successfully gained access using ssh,
- Create the portainer folder in the location where you organize your containers, in my case:
mkdir /volume1/docker/portainer
test@NAS:/volume1/docker$ ls -ltr
total 0
drwxrwxrwx+ 1 test users 0 Feb 16 15:24 portainerAfter you've created your folders and subfolders, execute the docker command:
sudo docker run -d --name=portainer \
-p 8000:8000 \
-p 9000:9000 \
-v /var/run/docker.sock:/var/run/docker.sock \
-v /volume1/docker/portainer:/data \
--restart=always \
portainer/portainer-ceTrought Docker compose
- Prerequisites?
Check to see if Docker Engine and Docker Compose have already been installed.
After that, create a new file named docker-compose.yml in the same directory as /volume1/docker/portainer and paste the code below into it.
version: '3.3'
services:
portainer-ce:
container_name: portainer
ports:
- '8000:8000'
- '9000:9000'

- '/var/run/docker.sock:/var/run/docker.sock'
- '/volume1/docker/portainer:/data'
restart: always
image: portainer/portainer-ce- run the following command using the docker compose command:
test@NAS:/volume1/docker/portainer$ sudo docker-compose up -d

How to use Portainer to manage your Docker containers
Once you have installed Portainer on your Synology NAS, you can use it to manage your Docker containers. To do this, you first need to create a new container. You can do this by clicking on the "Create New Container" button in the top left corner of the Portainer interface.
When creating a new container, you will need to provide a few pieces of information. The first is the name of the container. This can be anything you like, but it's a good idea to choose something that reflects what the container contains. The second is the image to use for the container. This can be any Docker image that is available on your Synology NAS or online.
The third piece of information is the command to run when the container is started. This is optional, but it can be useful if you want to run a specific command when the container starts up. For example, you could use this to start a web server in the container.
