Add docker image

[milaq]

Some may find the deployment cumbersome. Create a nice docker image for those.

[mnasec]

Hi Milaq, attached you will find a basic dockerfile for building a ycast container. The container will be about 76MB and is based von alpine linux. It builds the container based on your ycast 1.0.0 you released today. Just put both files in a directory an build your own image. It works for me on the synology NAS also.

#docker build --compress -f ycast-dockerfile-v6 -t yourrepro/ycast-docker:v6 .

ycast-docker.zip

[milaq]

Thanks :+1: I'll have a look at it.

[mnasec]

Hi Milaq, i optimized the image and deleted all unnecessary stuff out of the image, include the *.pyc files, they will be recreated during runtime. Now the image is about 40MB as a tar file using this dockerfile: ycast-docker-v9.zip Attached you will find the file as tar.gz: ycast-docker-v9.tar.gz

Hi Milaq, mnasec,

Excellent work. I posted a docker image in docker hub (https://hub.docker.com/r/netraams/ycast-docker. Had to make one small change to the permissions of bootstrap.sh

[Yocee84]

Hi! Please write step by step he install.

I use docker in Synology. I found the image. I installed with no lucky. We need special settings? ( especially the volume and the install path? what is it?) or we need a simple install? But when i ssh to syno as root, cant fint anything in ycast in opt.

[MaartenSanders]

Hi Yocee84, I don't have a Synology but just a regular docker install.

The container folder /opt/ycast/stations is linked to host folder /mnt/data/docker_appdata/ycast/opt/ycast in the host folder I have one file: stations.yml with contents:

Hi, thank you for this great projekt! Based on your work and the dockerfile of netraams I created a docker for Raspberry Pi: Github and Docker Hub

Run it with the following command (or create your own with the description in Github or Docker Hub): docker run -d --name vtuner-ycast -v /home/vtuner/:/srv/ycast/ycast/stations/ -p 80:80 --restart unless-stopped mpvd/vtuner-emulator-ycast:latest

Have fun! :-)

Hi Milaq, mnasec,

Excellent work. I posted a docker image in docker hub (https://hub.docker.com/r/netraams/ycast-docker. Had to make one small change to the permissions of bootstrap.sh

Hi @MaartenSanders, thank you very much for your container.

A few questions cause I'm quite a noob. For info, i've deployed your container on my syno:

You write "Set YC_STATIONS=/opt/ycast/stations/stations.yml and bind a volume to /opt/ycast/stations/ where I drop my stations.yml file." but in the meantime you define the variables ENV YC_STATIONS /opt/ycast/stations.yml in the build files.

In the first case, if I bind my folder containing stations.yml to /opt/ycast/, the container will not start and I will have

/usr/bin/python3: No module named ycast in my log files

In the second case, If I bind a folder to /opt/ycast/stations, it will work properly.

Is this a bug ? or maybe you can explain to me why using /opt/ycast/ for stations.yml doesn't work ?

Thanks again for your work. It really helps.

It is not a bug. Just how you define your local volume mappings.

[Michi491]

Thanks, so If I understand correctly, I must define any folder betwen /ycast and /stations.yml for ENV YC_STATIONS and must map my local folder to this folder ?

[MaartenSanders]

Michi491,

I have difficulties to understand the issue your are facing, I works now isn't it? As I write my setup is to Set YC_STATIONS=/opt/ycast/stations/stations.yml and bind a volume to /opt/ycast/stations/ where I drop my stations.yml file. So yes, it is different in the build file but that is how it came in the v9 version of mnasec (FWIW I use portainer so set the ENV from there). The only change I made to the docker file was on the permissions of bootstrap.sh.

[Michi491]

Yes, it works, no prob. I was just curious and initially thought it could also works without adding "/stations/". Thanks again

[mpvd]

Hi all, thank you for the new Version (1.1.0) of YCast. It works great! I integrated it also in my Docker for RaspberryPi and made a lot of adjustments inside the docker: https://hub.docker.com/r/mpvd/vtuner-emulator-ycast For any questions let me know.

[toastemeister]

For anyone trying to get a traefik rule for use with a Yamaha I eventually discovered that my Yamaha v677 was not sending a host header so my attempts to use that in the traefik rules were failing.

I was able to use an User-Agent rule though. For my Yamaha the User-Agent was: User-Agent: AV_Receiver/3.1 (RX-V677)

traefik 1.7 rule I used was: traefik.frontend.rule: "HeadersRegexp:User-Agent,AV_Receiver*"

This should match other Yamaha models / firmware updates but if not you might need to intercept the request in Wireshark to find out what the User-Agent your amp is sending.

Likely any proxy solution that uses the host header to direct requests to the correct backend, such as Nginx, will have a similar issue with these Yamahas.

I set up netraams/ycast-docker:latest on portainer and got a problem. I hope you can help me.

Here are my portainer settings:

I created a new file called stations.yml in the directory /opt/ycast/stations/stations.yml. This is the content:

The DNS Server is set up.

When i enter denon.vtuner.com I get redirected to my Ycast Server http://192.168.1.2/ycast/. The page shows:

The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.

Is your stations.yml indented as YAML correctly ?

[MaartenSanders]

Can you try attached stations.yml file (rename it to stations.yml)? I do recall ycast is a bit picky on the format. Is there a CRLF after you last line? I think it is needed. stations.yml.txt

[2003flo]

I deleted the container and deployed it again. Now the Radiobrowser feature works (yeah!) but the stations.yml doesnt work.

The log says:

I used the stations.yml.txt from MaartenSanders. I uploaded it into that directory /opt/ycast/stations/ and renamed it to stations.yml.

[ghost]

Should probably be YC_STATIONS | /opt/ycast/stations/stations.yml

[ghost]

You can find out what's actually the path in your container by running ls in it: docker exec -it ycast /bin/ls /opt/ycast/stations docker exec -it ycast /bin/ls /opt/ycast etc. Make sure to replace 'ycast' with your container name (list container names with docker container ls)

[2003flo]

Thank you cranphin. Editing YC_STATIONS worked for me.

[mnasec]

Added small changes to ycast-dockerfile to support actual alpine Linux. Additional one change in env YC_VERSION to build a image of the actual version with all commits (master.zip). In this case just set 'YC_VERSION master' ycast-docker-v13.zip

Runs on my synology without and modifications, just run 'chmod +x bootstrap.sh' before running the build command:

usage: docker build --compress -f ycast-dockerfile-v13 -t yourrepro/ycast-docker:v13 .

Image size will be about 46MB

Likely any proxy solution that uses the host header to direct requests to the correct backend, such as Nginx, will have a similar issue with these Yamahas.

That one helped me, thank you!

In my case I am running Caddy as proxy-server and I had to add the following lines

:80 {
    @ycast {
        header User-Agent AV_Receiver*
    }
    handle @ycast {
        reverse_proxy <YCAST-SERVER-IP>:<YCAST-SERVER-PORT>
    }
}

(obviously changing the <YCAST-SERVER-IP> and <YCAST-SERVER-PORT> with the correct values)
