I'm trying to rewrite the path to the service while preserving the browser url with nginx ingress on kubernetes.

What I need is this:

  • http://example.com/path => http://service
  • http://example.com/path/bar => http://service/bar
  • http://example.com/path/file.css => http://service/file.css

That is, make the /path be the root (or some different url) in the upstream server.

From what I see here, this is done using a trailing slash on the proxy_pass, but nginx ingress doesn't seem to have this option.

Is this possible nginx ingress?

I have a couple hundred of servers connecting to HTTPS endpoints, and currently each one have a public IP address. I want to tunnel them through a smaller set of standard outgoing IP addresses that I can manage. I don't need filters, authentication, caching or anything. I just need an open port that exits through a specific fixed address.

It would be ideal to start a VM with an arbitrary number of interfaces, and start a service that opens a port for each outgoing interface. I can dynamically generate the configuration if needed.

Everywhere I look, I see squid as the recommended proxy server, but it sounds too much for what I need. Is it the best tool for this job?

I also looked at SSH tunneling, but it gets complicated to establish and maintain tunnels from each server. Ideally, I'd like for applications to simply use an http proxy server when needed.

Are there other options I'm not seeing to achieve this?

Thanks in advance.

How can I set a custom log file for each postfix instance?

Specifically, I need to identify entries generated for different instances of postfix, and would be better for the tooling if each instance had its own log file in a different folder.

It seems I can specify syslog_name and syslog_facility on main.cf. The first one only changes the text prepended to the log entry in mail.log, so the log file is the same, the second seems to allow me to redirect the log to a different file, but appears be limited to only 8 different entries in syslog (local0-7) and a lot of apps already use that and I fear log entries not related to postfix end up appearing there.

Is this the only way or am I missing something?
