Testing with a clean ubi8 container, I'm still seeing Nginx 1.14 as the default Nginx. I see in your output is filtered out by modular filtering how was that done?

solohan83 commented 3 years ago

Hi,

Good catch on the modular filtering part!

After I spending some more time on this, I believe I have a better understanding of what is going on.

First, to answer your question of how modular filtering is done:

https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/deploying_different_types_of_servers/setting-up-and-configuring-nginx_deploying-different-types-of-servers

Second, I am not sure how UBI8 container handles it, as I personally never used it, but only full blown RHEL8 OS. (Yes, I am old school :) )

3rd, I was mistaken that nginx 1.14 is no longer provided. As RHEL 8.3, it seems it is proving 3 versions of nginx:

Hint: [d]efault, [e]nabled, [x]disabled, [i]nstalled

We have enabled 1.16 at one point for the repo, as 1.14 is considered exposing too many issues and vulnerabilities.

    - name: Reset the nginx module stream for RHEL8
      shell: dnf module reset nginx -y

    - name: Enable the nginx 1.16 app module stream for RHEL8
      shell: dnf module enable nginx:1.16 -y

Now, to the question:

If I would like to use nginx-mod-http-passenger version 6.0.8 for Nginx 1.16 or even 1.18 on RHEL 8, what is the best way of doing it?

Thanks.

CamJN commented 3 years ago

hmm I wonder if we can create module streams for passenger to match the nginx module streams... of course they don't exist in el7 so it might be tough.

Anyway, for now the best approach depends a bit on what kind of setup you have. If you have one server that you don't tear down and rebuild a lot then building an nginx module would probably be easiest, if you have several servers or rebuild a lot then you'll probably want to make your own rpm. I can provide some guidance either way if you let me know which is a better fit.

solohan83 commented 3 years ago

Thanks for the respond.

If there is a possibility that make the streamers to support the versions of Nginx provided by Redhat AppStream in the next release(6.0.9?), I am willing to wait.

For us, Nginx 1.14 is an unusable version, and it is our best interest to have the package provided from the vendor through the official repo.

If the possibility of making it happen is not feasible in the near future, I will start look into the route of using Apache instead of Nginx, as a quick test seems there is only one version of Apache is provided, and mod_passenger was installed no problem. Not sure how much the application will like it though.

CamJN commented 3 years ago

That depends if I'm able to get module streams working in our repo. I honestly do not know what that will require so I can't promise it'll make the next release.

CamJN commented 2 years ago

got more info in https://github.com/phusion/passenger/issues/2431

CamJN commented 1 year ago

we switched to the newest nginx module stream in 6.0.18, still don't support multiple versions but at least it's not super old
