tmpfs mounts not full describe in portainer

[rnz]

Description
tmpfs mounts not full describe in portainer
and can't create mounts from portainer by tmpfs

image

Steps to reproduce the issue:

1. create container with tmpfs mounts
   docker service create
   --name testservice
   --mount type=bind,source=/data/service/s0001/db,target=/var/lib/postgresql
   --mount type=tmpfs,target=/tmp
   --mount type=tmpfs,target=/var/tmp
   --mount type=tmpfs,target=/var/run
   --mount type=tmpfs,target=/run
   --network nginx-network
   --mode replicated
   --replicas 1
   docker-repo/testimage

2. go to service details, look at mounts - tmpfs mounts not fully visualisable

Technical details:

• Portainer version: 1.14.0
• Target Docker version: 17.04.0-ce
• Platform: Debian GNU/Linux 9.0 (stretch)
• Command used to start Portainer:

docker service create \
    --name portainer \
    --publish 9000:9000 \
    --constraint 'node.role == manager' \
    --mount type=bind,src=/var/run/docker.sock,dst=/var/run/docker.sock \
    --mount type=bind,src=/data/portainer,dst=/data \
    portainer/portainer \
    -H unix:///var/run/docker.sock

• Target Swarm version (if applicable): 17.04.0-ce
• Browser: Any

@G07cha Have a look at the TaskTemplate.ContainerSpec.Mounts field in the ServiceCreate operation: https://docs.docker.com/engine/api/v1.30/#operation/ServiceCreate

[G07cha]

@deviantony, yeah, I've deleted my previous comment because I've also found that it's possible to do through ContainerCreate.HostConfig.Mounts, so I'll be looking into that.

Not sure if totally relevant to this issue, but I needed a tmpfs mount to link within portainer and have used the example from the docker site:

docker volume create --driver local \
    --opt type=tmpfs \
    --opt device=tmpfs \
    --opt o=size=100m,uid=1000 \
    foo

It's then selectable just as any volume.

how? see my checkmk example below. How do you 'reference' this or assign it to the container using the UI alone?

I dont know if this is related, and/or a bug in portainer, but when creating frigate containers according to: https://docs.frigate.video/frigate/installation#docker, portainer is not able to duplicate/edit that container, because of the tmpfs (afaik)

Has anybody got a hint on how to solve it?

Have you tried like this

  frigate:
    container_name: ${frigate_name}
    image: ghcr.io/blakeblackshear/frigate:stable
  # privileged: true
    <<: *config   
    depends_on:
      - homeassistant
    shm_size: "192mb"
    networks:
      eth0:
        ipv4_address: ${frigate_ip}
      ha-netmqtt:
    ports:
      - "5000:5000" # Port used by the Web UI
      - "8554:8554" # RTSP feeds
      - "8555:8555/tcp" # WebRTC over tcp
      - "8555:8555/udp" # WebRTC over udp
      - "1984:1984" # go2rtc server HA integration
    volumes:
      - /etc/localtime:/etc/localtime:ro
      - ${dockerdir}/Frigate:/config
      - /mnt/user/Storage/CCTV:/media/frigate
      - type: tmpfs # 1GB of memory
        target: /tmp/cache
        tmpfs:
          size: 1000000000
    environment:
      - FRIGATE_RTSP_PASSWORD
      - PLUS_API_KEY

How i do configure the "tmpfs" bit in this checkmk example using the GUI on its own?

This is how it's done on the CLI. Im not interested in docker compose.

docker container run -e CMK_SITE_ID="mysite" -dit -p 8080:5000 -p 8000:8000 --tmpfs /opt/omd/sites/mysite/tmp:uid=1000,gid=1000 -v monitoring:/omd/sites --name monitoring -v /etc/localtime:/etc/localtime:ro --restart always checkmk/check-mk-raw:2.1.0-latest

Even if i configure the "local tmpfs" stanza as a volume in portainer how on earth do you reference it using the UI?
