Unable to start service with NVR in Docker container

[rlust]

This is a great script. I have it running on a NVR docker container but am unable to start the service.

Any info on getting the service portion to install would be helpful!

I am using ubuntu.

I just returned from vacation so I'll take a look at this soon, I have a few ideas

Hmm.. Thought about this, does your Unifi docker container have the log directory configured as an external volume? If so, then maybe we can build another docker container with this script that can watch the same log file. Shouldn't be that hard to do, I'll see if I can get it working.

@rlust I've added a Dockerfile that you can try. You will need to build the container on your docker host and then specify the volume where your log file is.

Here is the way I suggest you test this out:

• Clone the repo into a directory

• Edit the variables in the unifi-video-mqtt.sh file in the directory that you cloned the repo as this file will be copied into /usr/local/bin inside the container

• Build the docker image:

  docker build . -t unifi-video-mqtt

• Run the container in interactive mode specifying your log volume and then do the Harlem Shake in front of your camera to trigger the motion detection:

  docker run -it -v /path/to/unifi/log/volume/:/var/log/unifi-video unifi-video-mqtt

• If that all works, then you can run this container in the background:

  docker run -d --name unifi-video-mqtt --restart always -v /path/to/unifi/log/volume/:/var/log/unifi-video unifi-video-mqtt

Let me know if that works for you and if it is all good I'll add it to the official docs!

[rlust]

I will give it a try!

Thanks for the help! I do not think this will work as my Unifi-Video is running on UNRAID as a Docker, and I cannot figure how to get access to the log file for this new docker container. I am not that good with docker. I cannot figure out how to enter the path to the Unifi log file. Ideas?

When you build or re-build your unifi video container, you would have to add a volume like this so the mqtt container can access the same log file:

-v /path/to/unifi/log/volume/:/var/log/unifi-video

[rlust]

Giving it a try. Not sure if I did this right. Here is the volume mapping in Portainer.

Host/volume	Path in container
/mnt/cache/appdata/unifi-video	/var/lib/unifi-video
/mnt/user/UnfiVideoShareForStorage	/var/lib/unifi-video/videos
/path/to/unifi/log/volume	/var/log/unifi-video

[mzac]

right, the issue is you should probably put something like this for your setup

-v /mnt/user/UnifiVideoLogs:/var/log/unifi-video

as what I put before was an example

[rlust]

I got the docker running! Here are the messages in the log.

Is the above error an improper use of grep in a script?

edit out the -1n after grep

I changed the Docker file to the following but I was after it doing a few more things..
