• Accepted default ‘Container’ folder & location ‘to store images & containers’
• Warnings on startup:
  • LXC containers no longer supported after 20211231
  • The current page size of the system is 32K. Ensure that third-party applications are compatible with the current page size before installing the application. For details, see the FAQ:
    • QNAP updated the system page size from 4K to 32K for better performance and user experience on the following 32-bit ARM devices. This change in the compute environment could limit the container’s access to memory. To avoid container segmentation faults, verify third-party container page size compatibility before installation

Portainer install:

• Added new Share for Container/Docker persistent data ‘Docker’ on SysDefault volume
  • Added child folder ‘portanier’
• Gave myself RW access to share ‘Homes’
• Created Docker Compose YAML file ‘portainer.yml’ in my home share

version: '3'
services:
 portainer:
  container_name: Portainer
  image: portainer/portainer
  restart: always
  ports:
  - "9000:9000"
  volumes:
  - /var/run/docker.sock:/var/run/docker.sock
  - /share/Docker/portainer:/data

Putty:

$ docker-compose -f portainer.yml up -d

Container Station, started Portainer, and yes can login in at port 9000 but..

• Container station shows Application name as my username
• Trying to stop Portainer in Container Station says
  • Failed to stop application, Application not found myusername
• Stopped Portmainer from its own management window
• Now in Container station trying to start it again I get: Failed to start application, Application not found myusername
• Same issue if try to remove the container, application username not found

So removed it via:

$ docker system prune
WARNING! This will remove:
  - all stopped containers
  - all networks not used by at least one container
  - all dangling images
  - all dangling build cache

Deleted Networks:
myusername_default

In Container Station: Did Create -> Create and pasted in above YAML, also set ‘Application name’ field to ‘Portainer’

• yes it created a named application which I was able to start, but no connection at port 9000

Cleanup again:

$ docker system prune
WARNING! This will remove:
  - all stopped containers
  - all networks not used by at least one container
  - all dangling images
  - all dangling build cache
