Associate port forward to a domain name

[merlindorin]

Is your feature request related to a problem? Please describe.
I can have a lot of port-forward but naming them and having the ability to use them easily will be nice :).

Describe the solution you'd like
Add the ability to associate a domain to a forward. A local reverse proxy would be nice :) .

Describe alternatives you've considered
Nope, I am lazy

quick thought on a solution - i'd have to change the /etc/hosts file on the machine, and that might mess things up on the user's local machine.

but i'll think on it and circle back with more info...

having the domain with the same alias would be a cool feature, thanks for the feedback!

[hcavarsan]

@merlindorin released ! https://github.com/hcavarsan/kftray/releases/tag/v0.9.0

when adding a new configuration, you can now choose to use an alias as a local domain name. If this option is enabled, when starting a new port forward in this configuration, kftray will add a new entry to the host file of the OS. This entry will add the alias and the local address. (this entry will be removed when port forwarding stops.)

can you check if it helps?

If you have any questions, please let me know

[merlindorin]

This is awesome, gonna check that once I am back from vacation . Thx!

Hi @hcavarsan , checking the feature and it is not working. I also checked the host file and it is unmodified.

I have this configuration:

Some check I've done:

I used the link to open it in the browser. Didn't work.

curl http://argocd.cluster:8090/
curl: (6) Could not resolve host: argocd.cluster

ping argocd.cluster

ping: cannot resolve argocd.cluster: Unknown host

cat /etc/hosts

##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting.  Do not change this entry.
##
127.0.0.1	localhost
255.255.255.255	broadcasthost
::1             localhost
# Added by Docker Desktop
# To allow the same kube context to work on the host and the container:

hey @merlindorin , im reopening the issue to look into it... could you give me some more details:

• what OS are you using?
• did you try closing and reopening the app to see if the issue persists?
• could you try installing the app via Homebrew to see if the same issue occurs?

ill see if i can simulate the issue on my end.

thx for the feedback!

[hcavarsan]

hey, @merlindorin! are you still having the issue with the alias?

[merlindorin]

Re, sry for the delay.

• what OS are you using? MacOS 14 Sonoma on M1.
• did you try closing and reopening the app to see if the issue persists? Yes, and the issue is still there
• could you try installing the app via Homebrew to see if the same issue occurs? Not working

btw, the brew installation method does not work on MacOS. The installer needs pnpm and even if it is installed it still need it...

@merlindorin got it! to install with brew, you need to install xcode first using xcode-select --install. I'll include this info in the readme. thanks!

also, could you run KFTray with enabled logs and check for errors in the logs? you can share the logs with me if you prefer.

io generate the logs, run this command in the terminal:

RUST_LOG="trace" KFTRAY_DEBUG="true" open /Applications/kftray.app

The logs file will be created in $HOME/.kftray/app.log.

[merlindorin]

xcode is already installed. The issue is sh: pnpm: command not found (even installed locally, do not want to work :/ ).

About the issue by itself... well it is now clear enough:

[2024-04-14T06:50:21Z ERROR kubeforward::port_forward] Failed to write to the hostfile for argocd-server: Permission denied (os error 13)

[hcavarsan]

@merlindorin It looks like the problem is with the /etc/ directory being quite restricted. I'm going to look into a solution for this. In the meantime, there are two possible ways to address the issue and use the aliases:

1. Run sudo chmod ugo+rw /etc/hosts to grant write permission to this file.
2. Execute kftray with sudo by running sudo /Applications/kftray.app/Contents/MacOS/kftray.

These solutions are not the most secure since they grant write permission to the file itself, but they will resolve the issue for now. I'll keep this issue open to track the progress of the possible implementation to a more secure way (although it's unclear if that's feasible, as the app requires write permissions in the hosts file), is that okay with you?

Regarding the pnpm point, I've fixed it here: hcavarsan/homebrew-kftray@a6edaff. Now, if you run brew update and brew install, it should work :)

Thank you for the analysis and logs.

[merlindorin]

Awesome! Thanks a lot. Each day is a better day ;)

[hcavarsan]

cool @merlindorin, i opened issue #230 to track and improve the local domain changes. thx for reporting these issues with kftray, it really makes the app better and more consistent :)

[mprimeaux]

Has this issue been addressed?
