Hi, It could be a permission issue. If you have the /app/log folder mapped, try to remove it to test if that works. Try checking these docs as well https://github.com/jokob-sk/NetAlertX/blob/main/docs/FILE_PERMISSIONS.md Hope this helps, J

It works without volumes so it is a permissions issue but I'm not sure why. I've installed this on my Pi micro SD card many times and it works. Now I'm installing it on a freshly formatted external SSD card and it doesn't.
I tried this:
getent group www-data
www-data:x:33:netextra

sudo groupadd -g 82 www-data
groupadd: group 'www-data' already exists

Hi @netExtra ,

Glad to hear it is working without mapping the /app/log location, at least we know it is setup related.

I'm not a permissions wizard so I'd try to grant everyone a+rwx and see if that works. Then I would try to slowly remove permissions.

You can also try to SSH into the container and inspect permissions in there, they might not be mapped as expected.

Please report back and I can update the guide with more details.

Hope this helps,
j

I'm encountering the same issue for some reason. When I run it directly through Docker, it works, but it doesn’t function with Docker Compose even if I remove all the volumes.

     container_name: netalertx
    # use the below line if you want to test the latest dev image
    # image: "jokobsk/netalertx-dev:latest"
    image: "jokobsk/netalertx:latest"
    network_mode: "host"
    restart: unless-stopped
    environment:
      - TZ=Europe/Berlin
      - PORT=20211

Hi @syerad ,

I just tried spinning up a fresh container with this compose file and it seems to come up without issues:

services:
  netalertx_prod:
    container_name: netalertx_prod
    image: "jokobsk/netalertx:latest"
    network_mode: "host"
#    volumes:
#      - ${APP_DATA_LOCATION}/netalertx_prod/config:/app/config
#      - ${APP_DATA_LOCATION}/netalertx_prod/db:/app/db
    environment:
      - TZ=Europe/Berlin
      - PORT=22224
      - APP_CONF_OVERRIDE={"SCAN_SUBNETS":"['192.168.1.0/24 --interface=eth1']","GRAPHQL_PORT":"20225"}

I only specify APP_CONF_OVERRIDE since my port for the GRAPHQL server 20212 is already used

1. Even the message is the same, could you please post the whole error message you are getting?
2. Also, try to delete the container (including temp volumes), image and re-create the container in case the virtual volumes are acting up.
3. Can you post the command you use to spinning up the container?

Thanks,
j

Same problem here.

Thanks @jokob-sk ! I tried the same and it seems to work now. I guess the volumes were acting up. In the next step I'll try re-attach the volumes one by one. Pretty sure it's a permission issue but not yet sure how to resolve it.

Thanks again for your support!

[jokob-sk]

@syerad - thanks for the info!

@akorb90 , can you try the following:

1. Backup your setup as per: https://github.com/jokob-sk/NetAlertX/blob/main/docs/BACKUPS.md
2. Delete the container (including temp volumes), and image
3. Re-create the container
4. Can you post the command you use to spinning up the container?
5. If above doesn't work, can you try commenting out: #- ${APP_DATA_LOCATION}/logs:/app/log

[ingoratsdorf]

The issue is here:
FileNotFoundError: [Errno 2] No such file or directory: '/app/log/plugins/last_result.AVAHISCAN.log'
This happened to me as well with MQTT and other plugins.

Looks like the container is not creating the /app/log/plugins folder.
This is my workaround:

• plugins_vol:/app/log/plugins

name: netalertx

services:

  netalertx:
    container_name: netalertx
    # use the below line if you want to test the latest dev image
    # image: "jokobsk/netalertx-dev:latest"
    image: jokobsk/netalertx:latest
    network_mode: "host"
    restart: unless-stopped
    privileged: true
    volumes:
      - /opt/netalertx/config:/app/config
      - /opt/netalertx/db:/app/db
      - log_vol:/app/log # use tmpfs
      **- plugins_vol:/app/log/plugins # use tmpfs**
      - api_vol:/app/api # use tmpfs

    environment:
      - TZ=Pacific/Auckland
      - PORT=20211
volumes:
  api_vol:
    driver_opts:
      type: tmpfs
      device: tmpfs
  log_vol:
    driver_opts:
      type: tmpfs
      device: tmpfs
  plugins_vol:

Hi @ingoratsdorf ,

I just checked a fresh installation and the folders seem to be created fine:

Here's my compose:

version: "3"
services:
  netalertx_fresh:
    container_name: netalertx_fresh
    image: "jokobsk/netalertx-dev"
    network_mode: "host"
    volumes:
      - ${APP_DATA_LOCATION}/netalertx_fresh/config:/app/config
      - ${APP_DATA_LOCATION}/netalertx_fresh/db:/app/db
    environment:
      - TZ=Australia/Sydney
      - HOST_USER_ID=1036
      - HOST_USER_GID=1000
      - PORT=22222
      - ALWAYS_FRESH_INSTALL=true
      - APP_CONF_OVERRIDE={"SCAN_SUBNETS":"['192.168.1.0/24 --interface=eth1']","GRAPHQL_PORT":"20223","UI_theme":"Light"}

Maybe so. But @ingoratsdorf has the exact same error message I was receiving so I will try his solution. I'm sure it is a file permissions issue that is happening because I am using an external SSD and not the main internal SSD card in my Rasberry Pi. I just don't understand why this app has this permissions problem.
