I am also facing problem

Answer 2 · 2024-01-30T13:34:58.000Z

Anyone knows the alternative, it's not working for me as well

Answer 3 · 2024-04-02T17:58:03.000Z

Has anyone managed to crack this nut?

Answer 4 · 2024-04-18T14:46:50.000Z

same (localhost, docker desktop)

Answer 5 · 2024-04-26T11:14:25.000Z

same. But as the last commit is already 4 years old, I guess there won't be anything happening.

I've fixed some issues and produced a smallish alpine-based image.

To persist settings, mount a volume to /data. For example:

# https://github.com/thielj/NATS-WebUI/pkgs/container/nats-webui
mkdir ./nats-webui && chown 1000:1000
docker run --rm -p 8080:80 -v "${PWD}/nats-webui:/data" ghcr.io/thielj/nats-webui:latest

@autokilla47 Sorry URL was messed up. Try:

it can not run with bind error， as follows:

Have you actually used my version here?

https://github.com/thielj/NATS-WebUI/pkgs/container/nats-webui

The failed bind is probably an indication that something else is already listening on the port.

Answer 12 · 2024-09-30T10:15:48.000Z

I use the version nats-webui:v0.1.2 with docker pull.
The port should not be occupied by something else because container networking is not host.

Answer 13 · 2024-10-03T12:22:15.000Z

@zn-luo Do you have SELinux or something else in place that prevents container applications without root privileges to bind to ports lower than 1024?

@zn-luo Do you have SELinux or something else in place that prevents container applications without root privileges to bind to ports lower than 1024?

Maybe run cat /proc/sys/net/ipv4/ip_unprivileged_port_start inside the container.

@zn-luo Do you have SELinux or something else in place that prevents container applications without root privileges to bind to ports lower than 1024?

Maybe run cat /proc/sys/net/ipv4/ip_unprivileged_port_start inside the container.

It can not run with --sysctl "net.ipv4.ip_unprivileged_port_start=1024",

Answer 16 · 2024-10-09T09:08:35.000Z

@zn-luo I'm afraid there are only two options here: (1) fix your setup so the container can bind to ports lower than 1024; or (2) change the app to bind to e.g. port 8080 instead - or use an environment variable to override the default.

See https://github.com/thielj/NATS-WebUI/blob/0d6e4b0c1b499aa6013c4b07eee0c7d94784660d/src/main.rs#L162

I can run up a container with ghcr.io/thielj/nats-webui:v0.1.2 in docker Version 27.3.1, but after adding a nat server ,the status is Unreachable
