Angular CLI support for subdomain reverse proxy - firebase

suppose id like to have the following reverse proxy url redirection (for page loads):
https://abc.example.develop > http://localhost:4200
https://xyz.example.develop > http://localhost:4201
is there built-in reverse proxy support for subdomains in angular (cli) or nx? recently firebase has added support for multiple subdomains but how is one to serve them in development considering 1) they are different domains 2) firebase apis require https?
both the proxy.config.js way (https://angular.io/guide/build#bypass-the-proxy) and the environment files way look like they're made for a single app. do i need to make my own reverse proxy?

You'd have to do this outside of what Angular provides, since it is custom to your local machine.
The easiest option is to run nginx (or other reverse-proxy) locally (See https://docs.nginx.com/nginx/admin-guide/web-server/reverse-proxy/#passing-a-request-to-a-proxied-server)
Modifying your HOSTS file won't forward the port, so if you want to go that route, you'd need to use https://abc.example.develop:4200

I've created a solution that executes with the Angular CLI and where the proxy is run on a Node.js server. Nx support is in the proposal stage at the moment.

How to manage multiple symfony projects in a development computer

I've seen some post, including How to manage multiple backend stacks for development?, but nothing related to use lxc for a stable, safe and separate development environment, matching the production environment and regardless the desktop and/or linux distribution.
There was a feature previous to symfony cli release that allowed to specify a socket via ip:port, and this allowed to use different names in /etc/hosts using the 127.0.0.0/8 loopback network, so I could always use "bin/console server:start -p:myproject:8000", and I knew that using http://myproject:8000 (specified in /etc/hosts) I could access my project and keep the sessions, etc.
The symfony cli, as far as I've tried, doesn't allow this. Reading the docs, there's a built-in proxy in symfony cli, but though I've set a couple of projects to use this in the container, clicking on the list doesn't open the project (with .wip suffix), and issues an error about proxy redirections. If I browse to the port and ip of the container ip, it works perfectly, but the port is something that can change with every reboot of the container.
If there's nothing that can be set on the proxy side to solve this scenario, I'd ask to take back the socket feature that existed previously, so I can manage this situation as I used to do before, and solve this.
Thanks in advance.
I think I've finally found a good solution. I've created an issue to improve the situation that seemed not to work, so I'll try to explain for whoever might be interested.
I've setup the proxy server built-in with the symfony cli, but instead of allowing it to run with the defaults, I've had to specify --host=proxyhost (resolvable from the host) and setting proxy exceptions for .com, .org, .net, .tv, etc, together with setting a name to attach for every project (issuing symfony proxy:domain:attach myproject from inside the project dir), I can go to http://myproject.wip just like http://proxyhost:portX, no matter which port is portX.

Developing in local environment when using a CDN

I'm pretty new to CDN. I found a good free service that matches my needs in developing Wordpress (and also has a plugin for it). I already tried it on a remote project and it works.
Now, I usually develop websites in a local environment (http://my-project.test:9000) then I push to production on final domain (https://my-project.com).
Well, I don't understand how to work in a local environment with a CDN.
For instance, I tried configuring the plugin in local but it says needs https (never had to need to install an ssl certificate in local development). A CDN always needs HTTPS?
Also, in my head I should be able to use the same CDN key for 2 domain (for example the 2 above: one for local and one for production) so the static assets are "shared" for the 2 Wordpress installations.
So in general I'm really confused: how developing in local environment when you use a CDN?

How to proxy subdomains to other servers with dokku?

I want my dokku host to run the main nginx for my domain (let say cooldok.ku).
On cooldok.ku for some reasons I have other Virtual Machines serving content. I want to expose this content on a subdomain (say vm.cooldok.ku, runs in a VM at 10.0.0.7 on the cooldok.ku host).
I figured the involved methodology is called reverse-proxy.
In an optimal world, there would be a dokku-only way to register and 'link'/proxy the subdomains. As an added bonus, the cooldok.ku host would do the ssl-stuff for https itself (like ssltunnel) so that I could leverage existing certificates and/or use the awesome letsencrypt on the same machine and secure applications in the VM that were not meant to be served via https.
How can this scenario be realised with dokku? How difficult would it be to write a plugin doing that?
Update
So, basically dokku (0.8) comes equipped with exactly everything it would need. The question is, how much of what dokku wants to achieve (fire up those yummy docker containers) is in the way. To hack a setup which does what I want, following can be done:
# create folder where we want it
dokku apps:create vm
Now, these files have to be created/be present (vanilla 0.8 dokku installation)
#/home/dokku/vm/DOCKER_OPTIONS_DEPLOY
--restart=on-failure:10
#/home/dokku/vm/IP.web.1
10.0.0.7
#/home/dokku/vm/PORT.web.1
80
#/home/dokku/vm/URLS
# THIS FILE IS GENERATED BY DOKKU - DO NOT EDIT, YOUR CHANGES WILL BE OVERWRITTEN - I did it nonetheless
http://vm.cooldok.ku
#/home/dokku/vm/VHOST
vm.cookdok.ku
#/home/dokku/vm/nginx.conf
# Just listing changes from another default app
[...]
proxy_pass http://vm-host;
[...]
upstream vm-host {
server 10.0.0.7:80;
}
Afterwards, nginx needs a manual restart (or ... dokku can do something for us here)
I am pretty sure that some of the (redundant) information can be left out, as dokku should puzzle the nginx.conf itself, for example. I am not sure if this setup survives a reboot/nginx restart. Also, on tests, letsencrypt would not let me install the certificates/rebuild the nginx configuration because it sees the app vm as not being deployed.
Update2
To overcome the "app not deployed" issue, it suffices to touch /home/dokku/vm/CONTAINER, but this gets messier and messier ...
I bundled the information from the updates of my post into a dirty script at https://github.com/econya/scripts/blob/master/scripts/virt-helpers/fake-dokku-app.sh .
I guess the cleanest solution as-is with upwards compatibility would be to create a Dockerfile that launches a reverse proxy itself (configured via env/ config:set variables) - but I am happy to learn a smarter and nicer solution, or that I get paid to write a proper plugin ;)
Second approach would be to use a "Null"-Docker image together with a custom nginx template I guess.
Update 2021
According to the release notes it works now (look for "Routing to non-Dokku managed apps"):
https://dokku.github.io/release/dokku-0.25.0
I still use an older dokku and the solution written above, though.

uwsgi + xdv integration

i'm trying to configure uwsgi + xdv as a frontend for plone and other applications (this is why i don't use collective.xdv)
any hints?
If you want to use XDV via a WSGI proxy, you probably want to take a look at http://pypi.python.org/pypi/dv.xdvserver. The configuration instructions are for PasteDeploy, but if you are familiar with uWSGI you should be able to adjust them.
Note that Plone itself doesn't yet support WSGI, so it will run via its own normal web server.

Finding an HTTP proxy that will intercept static resource requests

Background
I develop a web application that lives on an embedded device. In order to make dev times sane, frontend development is done using apache serving static documents, with PHP proxying out to the embedded device for specifically configured dynamic resources. This requires that we keep various server-simulation scripts hanging around in source control, and it requires updating those scripts whenever we add a new dynamic resource.
Problem
I'd like to invert the logic: if the requested document is available in the static documents directory, serve it; otherwise, proxy the request to the embedded device.
Optimally, I want a software package that will do this for me (for Windows or buildable on cygwin). I can deal with forcing apache to do it with PHP, but I'm unsure how to configure it to make it happen. I've looked at squid and privoxy, but neither of them seem to do what I want.
Any ideas? I'd rather not have to roll my own.
Now, Varnish is available in cygwin, see:
Installation instructions: http://varnish-cache.org/trac/wiki/VarnishOnCygwinWindows
I think what you want is varnish.
Now that I've looked at varnish, I understand that what I actually want is a special case of a reverse proxy, and that squid can be configured to do what I need. (With the added bonus of having it available as a cygwin package.)
