Portainer NetAlertX Install Failure (Total Noob)

[APW219]

Struggling to get NetAlertX running. The image pulls, builds the container and starts. The URL is denied, presumably permissions. I have added notes form my install effort below. Any help is most appreciated. Be gentle, this is my first Docker install. ;)

Copy/Paste from https://github.com/netalertx/NetAlertX/

docker run -d
--network=host
--restart unless-stopped
-v /local_data_dir:/data
-v /etc/localtime:/etc/localtime:ro
--tmpfs /tmp:uid=20211,gid=20211,mode=1700
-e PORT=20211
-e APP_CONF_OVERRIDE='{"GRAPHQL_PORT":"20214"}'
ghcr.io/netalertx/netalertx:latest

Image pulls without issue, Portainer shows the new container/image.
Portainer container for NetAlertX is flagged 'unhealthy'

URL (http://192.168.0.50:20211/) replies '192.168.0.50 refused to connect' - (IP is that of the RasPi hosting Docker)
Confirmed port 20211 is not used by another image/application

confirmed dir has the required files (configm, db)
dockeruser@Docker:/local_data_dir $ ls

Ensure the config and database directories are owned by the netalertx user:
chown -R 20211:20211 /local_data_dir/config /local_data_dir/db
dockeruser@Docker:/ $ chown -R 20211:20211 /local_data_dir/config /local_data_dir/db

Hi there,

I'll try to help.

Can you post how your data folder structure looks?

For example, here's how I have my Docker app data set up:

jokob@Synology-NAS:/volume2/docker_appdata$ ls | grep netalertx
netalertx
netalertx_dev
netalertx_empty
netalertx_fresh
netalertx_prod
netalertx_temp
netalertx_test

Sample structure inside one of the folders:

jokob@Synology-NAS:/volume2/docker_appdata/netalertx_prod$ tree .
.
├── config
│   ├── app.conf
│   ├── app_conf_override.json
│   └── devices.csv
└── db
    ├── app.db
    ├── app.db-shm
    └── app.db-wal

3 directories, 15 files

So if I were to run the container, the volume mapping would look something like:

docker run -d \
  --network=host \
  --restart unless-stopped \
  -v /volume2/docker_appdata/netalertx_prod:/data \
  -v /etc/localtime:/etc/localtime:ro \
  --tmpfs /tmp:uid=20211,gid=20211,mode=1700 \
  -e PORT=20211 \
  -e APP_CONF_OVERRIDE='{"GRAPHQL_PORT":"20214"}' \
  ghcr.io/netalertx/netalertx:latest

Notice the host path:

/volume2/docker_appdata/netalertx_prod

This entire folder is mounted to /data inside the container.

You can also pre-create the config and db subfolders before starting the container. NetAlertX will try to create them automatically if they don't exist, but creating them yourself can sometimes help rule out filesystem or permission issues.

Also, the permission errors are a bit concerning:

chown: Operation not permitted
chmod: Operation not permitted

Those commands would normally succeed on a local Linux filesystem. Can you tell us a bit more about where /local_data_dir is located?

• Raspberry Pi OS, OMV, CasaOS, etc.?
• Local disk, USB drive, SMB share, NFS share, etc.?

Could you also post:

ls -ld /local_data_dir /local_data_dir/config /local_data_dir/db

and the container logs:

docker logs <container_name>

The logs should tell us more and why nothing is listening on port 20211.
