How to get a docker log

If you're running changedetection.io from the docker, it's as simple as calling this command:
docker logs changedetection.io &> logs.txt

No Notifications

Make sure you're not sending too long messages, as some notification targets do have message length limitations. (See https://github.com/dgtlmoon/changedetection.io/wiki/Notification-configuration-notes )

For example, too long notification message submitted to the Telegram will produce the following error in the log file:

WARNING:apprise:Failed to send Telegram notification to {ID}: Bad Request: message is too long, error=400.
DEBUG:apprise:Response Details:
b'{"ok":false,"error_code":400,"description":"Bad Request: message is too long"}'

You can easily get out of length limitations is you're including {current_snapshot} into the Notification Body.

Code Changes Not Reflecting?

If you are making changes to your local repository and they are not showing up in the Docker image, try the following:

Make sure you’ve tried using Docker composer instead of Docker standalone:

$ docker-compose up -d

In the likely case that this doesn’t fix the issue, you will need to edit the docker-compose.yml file. Edit the services section so it looks like the following:

services:
    changedetection:
      build: .
      container_name: changedetection
      hostname: changedetection
      volumes:
        - changedetection-data:/datastore

Workaround for 'pyinit_main: can't initialize time' error on Raspberry Pi

When using or installing changedetection.io at the Raspberry Pi device, you can experience these errors:

docker-compose top or docker top changedetection.io do return:

Error response from daemon: Container {CONTAINER_ID} is restarting, wait until the container is running

docker logs changedetection.io &> logs.txt produces logs with the following error:
```
pyinit_main: can't initialize time
```

As per https://github.com/linuxserver/docker-papermerge/issues/4, run these commands to workaround this problem:
wget http://ftp.us.debian.org/debian/pool/main/libs/libseccomp/libseccomp2_2.5.1-1_armhf.deb
sudo dpkg -i libseccomp2_2.5.1-1_armhf.deb
