Latest Docker container (2.7.0) - 404 when navigating to IP:7000

[blownupp]

Issue Template

Please fill in the issue as required.

• System: Ubuntu Docker Host
• Architecture: amd64
• Version: 2.7.0
• Problem Description: After launching the latest Neuron Docker container, navigating to the dashboard (x.x.x.x:7000) yields a 404 Not Found error. Switching to the previous release (emqx/neuron:2.6.3) works without issue - it's only when using emqx/neuron:latest or emqx/neuron:2.7.0 that this happens.
• Log Information:

Used this command:

docker run -d --network=mynet --ip=10.15.41.29 --name neuron -p 7000:7000 --privileged=true --restart=always emqx/neuron:latest

and

docker run -d --network=mynet --ip=10.15.41.29 --name neuron -p 7000:7000 --privileged=true --restart=always emqx/neuron:2.7.0

Starting with Neuron 2.7 the dashboard is no longer available, the UI is integrated into NeuronEX and can be used directly with NeuronEX. @blownupp @dbwaax

[kidproquo]

Shouldn't the documentation reflect this drastic change? All the docs (quickstart, etc.) refer to pulling the latest docker image and accessing the dashboard at http://IP:7000.

Im completely new to the project and wanted to try it out so if I start the neuron docker container as described I cant access the web ui. Do I have to start another docker container to access the ui? What does "the UI is integrated into NeuronEX" mean. Is the UI no longer available without a license?

any update?

As of today, 2.6.3 now installs WITH the license qualifier - so thats been changed too. Yet they still claim its open source albeit with only modbus and mqtt drivers. this is like claiming a box of free crisps that you have a voucher for. But it turns up empty. customer service says ahhhhhhh you expected crisps in your box of free crisps. nah nah nah.... you have to pay for those. you got your free box, whats the problem? But we will let you munch a few crisps for two weeks. then a couple more for another two weeks...

If you really want a working UI, you can copy the /dist folder from the official website image/files into the compiled version of the source code from this repo (Don't download the files from the release page). The neuron-dashboard repo seems to be lacking behind and is creating some issues when I attempted to run it with the latest version of the compiled neuron.

Just in case if you want a dockerfile to build this repo and run your own docker image for the "open source liscences", here you go:

Note

If you want UI, download the files from the official website, and copy the /dist folder to the directory you are running the docker build command.

Your folder should be something like this:

/dist
dockerfile

@joejej

Thanks - yes I actually just did a reinstall following the github instructions. installed emqx/neuron 2.10.2 deb. Then out of interest downloaded, and unzipped 2.4.9 neuron-dashboard - which unzipped into its own dist directory. The webpage opened straight up. No extra build or config needed. Then downloaded dashboard 2.6.3 - which was just source code. 2.4.9 still had the license limit contrary to the open source claim. 2.6.3 - im not going to bother doing a build. emqx has clearly made a commercial decision, and im not going to use a product on my own home that i could end up having to pay $300+ per month for.... I still have the complete 2.5.3 deb i can roll back to and works for me....

But whats this CE neuron you mention? An earlier fork? Just accessed cli? Im not having any success googling it up. :D with a name like neuron Im starting to feel like im trying to find a brain lab!

Apparently, the files from the GitHub release and the official website were not build directly from the code in this repo; They did some post processing in their shell script.
To actually use the "open source license" and get away with the tag and node limits, you will need to Build From Source. See #2351 for response from the repo maintainer.

The CE neuron that i refreneced is just the version that you build from source, sorry for the confusion.

@GripenANM thanks a lot, the dockerfile works as expected.
Can you pls send me an email on my github account? I have a cuople more things i would like to change there.

Thanks,
