Docker

[asmithau 9]

Hi All,

 

I'm playing around with OMV and I'm having all sorts of issues getting Emby to see the files within shares. I'm not a great Linux guy, so wondering if anyone can point me in the direction of a setup guide of some description?

 

In relation to the shares I can see them in OMV, but not the files.

 

Merry Christmas

Hello,

I am running emby server docker on unraid. 

Can I upgrade to netcore by changing Repository: from "emby/embyserver" to "emby/embyserver_netcore" ?

 

Can I keep my existing userdata folder and just upgrade this way? or will the docker I have installed upgrade by itself when its ready?

You should probably do a backup/restore instead of continuing to use the pre-existing config directory.

 

This has some more information about backup/restore procedures, https://github.com/MediaBrowser/Wiki/wiki/Backup.

I had no issues just changing the Repository. Loving the new version. My dockers backup once a week so I wasn't worried if something went wrong.

Thanks for the feedback guys.

[Handl3vogn 6]

Changed from mono to netcore version by just changeing the Repository and everything seems to be working fine.

 

Does anyone knows when the netcore versjon will be available in the CA apps tab for unraid?

Edited January 2, 2018 by Handl3vogn

[alucryd 216]

Since we're getting good feedback I think it's ready to hit the shelves. From the next stable release and onwards the regular repository will contain the netcore version.

Please see this before that

Fixed in the latest beta.

I have a problem with creating tvshow.nfo.

since a few versions ( its now on 3.2.60.8) there will series recognized and for each episode will get a episode-thumb.jpg and a episode.nfo but no tvshow.nfo

and so in emby you have an empty entry under season..

 

Emby is in a unraid docker

Found a problem with the netcore docker. When logging in from outside my network my web browser did not get my let's encrypt cert and reported the site as unsecure. Changed repository back to the mono version and ssl cert works like it should.

 

Edit

Or it seems like my web browser got the cert but did not accept it when using netcore version.

hi @@Handl3vogn, can you please attach the information requested in how to report a problem? thanks !

[Handl3vogn 6]

Here is logs. Mono log for working version and netcore for not working. Away from home so typing on my phone. When running netcore I even got a prompt to accept cert on emby mobile app. And I could see in the info that it was from let's encrypt but it did not seem to trust it.

Have you double checked that it's not expired?

[Handl3vogn 6]

Yes made a brand new one just to test. And it seems to accept it if the browser had seen the cert before. Like if I visited my lets encrypt web server first on port 443 and then went to 8920 I got the green lock. But if I cleaned all userdata from browser and went right to 8920 I get cert error.

I will try some more tomorrow. Like a new clean netcore install and see if that fixes it.
Maybe this is a problem from updating my docker to netcore with the same userdata folder that used to run mono.

But it seems like there is something from the cert that is altered or blocked before it gets to the web browser. After changing back to mono version I get the secure lock every time.

Update
Tried with a fresh version of netcore docker and same problem. To get cert error I have to uninstall and install browser on my phone (Using Firefox on Android for testing). Did not work to just delete userdata in browser.

it only happening if the browser newer been on my domain before.

 

Update2:

Made a windows10 vm running emby server and set it up using the same cert and on windows it works without problems.

So this must be a docker or linux problem. (mono docker is fine)

 

Update3:

Installed emby on a ubuntu vm and got the site not secure error.

 

Hope someone can test this on a embyserver running netcore on linux. And its important to use a device or browser that has not seen your cert before or it just accepts it. Did first notice this when my cert was up for renewal. and later when I was away from home and tried to connect from the hotel tv. Easy way to get consistent test is to download a browser on your phone and delete all appdata for that browser between each test.

Edited January 7, 2018 by Handl3vogn

[Handl3vogn 6]

Have you double checked that it's not expired?

Yes. it expires 06. apr 2018

 

And I have tried multiple Browsers, firefox and chrome on linux, android, windows. (deleted userdata folder between each test)

All give me cert error when my server is on linux netcore version. 

Mono linux and windows netcore gives me green lock (trust cert)

 

I create the cert using linuxserver's lets encrypt docker and convert it for emby by using this command:

cd /mnt/user/appdata/letsencrypt/keys/letsencrypt/ && openssl pkcs12 -inkey privkey.pem -in fullchain.pem -export -out emby.pfx -passout pass:

mv /mnt/user/appdata/letsencrypt/keys/letsencrypt/emby.pfx /mnt/user/appdata/EmbyServer/ssl/emby.pfx

Can someone help me get Emby-Server installed on a Raspberry Pi 2.

 

I've tried to install via non-docker method, as it's a big mess of installing tonnes of things via apt-get and eventually the system breaking (mainly from mono).

So I tried the docker install method and didn't do much better.

 

It's a brand new image of raspbian (stretch lite 2017-11-29).

 

So I try to run the following commands, as recommended:

 

sudo curl -sSL https://get.docker.com/ | sh

sudo docker run -it --rm --volume /usr/local/bin:/target emby/embyserver:armv7 instl service

 

But after it completes all the downloads for Emby and extracts them, it just exits.

There are no containers created when I try to list them.

I try running the 2nd command again, and it just exits again.

 

I have no idea how to proceed. I thought this would be a simple process, especially from a blanked system.

 

I'd appreciate some help please. Or if someone has a pre-built emby-server/raspbian .img I can just install onto the SD card (8GB).

Hi, why not try our new non-docker install that we're currently testing:

 

https://github.com/MediaBrowser/Emby/releases/download/3.2.60.9/emby-server-deb_3.2.60.9_armhf.deb

 

You can follow the instructions from the website:

https://emby.media/linux-server.html

 

Except use the .deb I'm linking to here.

 

Thanks.

Ok, I've removed docker and installed from the .deb file you linked. And rebooted.

I was expecting emby-server to start on boot, but it didn't.

I did a search for emby-server and found it in /opt, so tried to start /opt/emby-server/bin/emby-server

and it returned with: Illegal instruction

 

Any ideas? Where are the log files for this?

[alucryd 216]

@@rockhead006 That's usually because the binaries have been built with some instructions your CPU does not support. The buildflags have been changed recently to use the armv7-a instruction set, which should in theory be low enough to accomodate every armv7 cpu out there (at least that's what debian says and does). However all components haven't been rebuilt with these flags yet, I'm in the process of doing so.

I've just done a search, and it sounds like Illegal Instruction comes up with a ARMv7 image is installed onto a ARMv6 system. Raspberry Pi 2 is ARMv6. I assume your .deb is ARMv7. :-(

Yes, you are right. Sorry. It looks like I have a RPI 1 Model B, not a 2. Not sure why I thought I had a 2.
