Docker image on DockerHub

[zeppelinux]

Hi Ninjamers,

I added automated support for this workflow (GitHub + DockerHub):

Push Git Tag -> Linux Compile -> Create Release -> Add binary to the release -> Build Docker image from the release on DockerHub

Using forked from the official mirror GitHub repo: https://github.com/zeppelinux/ninjam
Image is available in DockerHub https://hub.docker.com/r/zeppelinux/ninjam-server

The description in the DockerHub repository is auto generated from the git readme.md and there is not much info, so here are some basic instructions:

$ docker run -v /path/to/ninjam/config.cfg:/usr/local/ninjam/config.cfg -p 2049:2049 --name ninjam zeppelinux/ninjam-server:v0.084

Out of the box configuration.cfg is a copy of example.cfg from the git repositiry, so it doesn't accept all network connections and not allowing anonymous login.

I'm plaining to create something (yaml's or Helm chart) for Kubernetes deployment as well.

NINJAM is awesome, appreciate the idea and the implementation very much!


Cheers,
Dmitry

This is awesome! I wonder how a Ninjam server would fare in a Kubernetes workload...

Thanks! I have it deployed (created a simple Helm chart, will share it soon) to the cluster and exposed, check it out open.jaminpeace.com:2049

When idle consumes very little resources, still looking forward to put some load on it

Helm Charts are created - makes everything highly automated.

Seems like I changed the config file name at some point (and broke the cmd line provided initially), fixed now.

There is also support for jam sessions persistence:

add/uncomment
SessionArchive /usr/local/ninjam/sessions/ 3600

docker run -v /path/to/ninjam/config.cfg:/usr/local/ninjam/config.cfg -v /your/local/sessions:/usr/local/ninjam/sessions -p 2049:2049 --rm --name ninjam zeppelinux/ninjam-server:v0.083

Hi, wondering if you've considered releasing this as a docker-compose file.

I noticed the docker releases are missing a "latest" tag usually assigned to most recent image. See this example: https://github.com/hpcng/singularity/issues/2825

Happy New Year!

Happy 2021!

Docker image 'latest' tag is considered as a bad practice, not sure if it worth to encourage to use it.

Docker compose can be useful when there is something to compose. NINJAM is just one container. Can you please elaborate why you need it?

[mkmusic]

I'm interested in running 2 - 3 Ninjam servers, so was thinking of using a compose file to simplify maintenance.

My understanding is latest is a tag so when executing `docker pull MyName/Ninjam` you'll receive the most recent release tagged "latest" automatically. Example, forum guide links v083 while docker lists v084 from a couple weeks ago.

Anyways, thanks for maintaining this!

[zeppelinux]

You can achieve what you need just by running the same command couple of times (change port & container name). Compose would help and there should be no problem to create one (pull requests are welcome
Saying that, if you really want to automate things - use Helm Charts to deploy to K8.
By not having latest your deployment is safe from auto-upgrade (and potentially from breaking changes), but I see what you mean.

Cheers!
Dmitry

In case somebody needs simple solution for attaching dynamic Ip (one that you get from your ISP) to some domain, so you can refer/publish your NINJAM server as my-domain.me:2049 (or whatever) here is the project I open sourced recently: https://github.com/zeppelinux/quarked-ddns

Hey Zeppelin, just dropping in to say THANK YOU for uploading the image. Just switched my private server from a Windows PC to a NAS with Docker - your image made this such an easy switch. Thx!

[zeppelinux]

This is awesome, Thanks brummbear!

Docker Hub is not free to upload new images anymore but whatever is there is still up to date. Will figure out something in case it needs to be updated.

oops - I did not know that. I mean, is that even true for public repos? I understand that hosting images costs money but for open source public repos this would be a big let down...

[zeppelinux]

They said Open Source projects are still ok, but these are some projects that they decide... I applied. At that time download counter already showed 100+ thousands, they still didn't get back to me.
