Can no longer create docker

[RadOD]

After a fresh install of the traccar docker I get an error that the command failed.  Unraid shows it created the docker, but attempting to start it fails. 

 

This is the error on install.  I'm not sure how to interpret and further debug this error:

The command failed.

 

 

I had it installed previously with no problems - but it used way more ports than I needed so I tried editing the container changing only the host port 1 and 2 from 5000-5150 to 5030-5035 which gave this error:

root@localhost:# /usr/local/emhttp/plugins/dynamix.docker.manager/scripts/docker run -d --name='traccar' --net='bridge' -e TZ="America/Chicago" -e HOST_OS="Unraid" -p '8083:8082/tcp' -p '5030:5000-5150/tcp' -p '5030:5000-5150/udp' -v '/mnt/user/appdata/traccar/logs/':'/opt/traccar/logs':'rw' -v 'https://raw.githubusercontent.com/traccar/traccar/master/setup/traccar.xml':'/opt/traccar/conf/traccar.xml':'rw' --restart always --hostname traccar 'traccar/traccar' 

/usr/bin/docker: invalid publish opts format (should be name=value but got '8083:8082/tcp').
See '/usr/bin/docker run --help'.

 

So I deleted the docker, under advanced I deleted to orphan image and I renamed the folder in appdata.

 

If anyone can tell me in general what is going on, I don't really know what is going wrong or where to start with these errors.

You're trying to assign a range of ports to a single port.   Map each individually.

 

And it's also complaining that you're attempting to map a file instead of a path (traccar.xml)

[RadOD]

But everything is default -- so I could not see how I could be doing that!

 

Since I was merely adjusting editing the port range I did not pay much attention to "Link to traccar.xml: https://raw.githubusercontent.com/traccar/traccar/master/setup/traccar.xml Add it to your host path before starting the container."  Turn out that even if you have created traccar.xml, docker installation modifies its files including deleting or moving the traccar.xml file. It looks as though you need to recreate traccar.xml each and every time you edit your docker.

 

And since traccar.xml is a configuration file, my guess is editing and restarting the docker with a new file may well wipe out any configuration you had.  Back-up!

No it's not.  This is a snip from a completely default install of traccar

-p '5000-5150:5000-5150/tcp' -p '5000-5150:5000-5150/udp'

Your output is

-p '5030:5000-5150/tcp' -p '5030:5000-5150/udp'

Default maps 5000-5150 to 5000-5150  You're trying to map 5030 to 5000-5150 (a single port to a range of ports)

 

You did this when you

If you only need the one port (5030), then you will also have to change the container mapping (which may require you to delete that mapping and add another one) to only reference a single port instead of the range.

I guess what I should have said was everything else was default.  I did not realize that I could not edit the ports and just restart a container.  In the end I was unable to even delete and rebuild with altered ports.  I have not yet taken the time to learn how this docker works internally but I get what you are saying now.  

 

Thanks for all the time you take responding to those of us 'learning the hard way'.
