Load balancers are the point of entrance to the datacenter. They are on the critical path to access anything and everything. That give them some interesting characteristics. First, they are the most important thing to monitor in an infrastructure. Second, they are in a unique position to give insights not only about themselves but also about every service that they are backing. There are two popular open-source software load balancers: HAProxy and nginx.Getting started with Caddy the HTTPS Web Server from scratch
These tools gather metrics from applications, servers and infrastructure. They allow to explore the metrics, graph them and send alerts. Integrating the load balancers into our monitoring system is critical. Needless to say, the monitoring capabilities will be limited by what information is measured and provided by the load balancer. Nginx only gives the sum, over all sites. It is NOT possible to get any number per site nor per application. The numbers are given globally, per frontend and per backend whichever makes sense.
They are available on a human readable web page and in a raw CSV format. The 7 nginx metrics are displayed on a human readable web page, accessible at No kidding. Here we can see which servers are up or down, how much bandwidth is used, how many clients are connected and much more. Whenever something goes wonky. Second, you open the HAProxy stats page to find what is broken.
The only hack we can do is parse the raw text, hopping no spacing will change in future versions. When there is nothing to get, there is nothing to display and nothing to alert on. Note : Some monitoring tools actually pretend to support nginx integrations.Traefik is the leading open source reverse proxy and load balancer for HTTP and TCP-based applications that is easy, dynamic, automatic, fast, full-featured, production proven, provides metrics, and integrates with every major cluster technology No wonder it's so popular!

If you are outside the network when you connect you can type in the complete IP address or domain name in the server field with the correct port to continue to the login page. You can find the default ports below to access the web frontend. This document aims to provide an administrator with knowledge on what ports Jellyfin binds to and what purpose they serve.
The web frontend can be accessed here for debugging SSL certificate issues on your local network. You can modify this setting from the Networking page in the settings. This setting can also be modified from the Networking page to use a different port. Since client auto-discover would break if this option were configurable, you cannot change this in the settings at this time.
DLNA also uses this port and is required to be in the local subnet. Allows clients to discover Jellyfin on the local network. A broadcast message to this port with Who is JellyfinServer? The server will select an unused port on startup to connect to these tuner devices. It's possible to run Jellyfin behind another server acting as a reverse proxy.
HAProxy vs nginx: Why you should NEVER use nginx for load balancing!
With a reverse proxy setup, this server handles all network traffic and proxies it back to Jellyfin. This provides the benefits of using DNS names and not having to remember port numbers, as well as easier integration and management of SSL certificates. In order for a reverse proxy to have the maximum benefit, you should have a publically routable IP address and a domain with DNS set up correctly.
These examples assume you want to run Jellyfin under a sub-domain ie: jellyfin. In addition, the examples are configured for use with Let's Encrypt certificates.
This setting requires a server restart to change, in order to avoid invalidating existing paths until the administrator is ready.
When setting a new Base URL i. However, entirely removing a Base URL i. This should be kept in mind when removing an existing Base URL. Client applications generally, for now, do not handle the Base URL redirects implicitly. Any reverse proxy configurations must be updated to handle a new Base URL.
Keep this in mind however when doing more advanced routing. It's strongly recommend that you check your SSL strength and server security at SSLLabs if you are exposing these services to the internet. Connectivity Many clients will automatically discover servers running on the same LAN and display them on login.

Warning In order for a reverse proxy to have the maximum benefit, you should have a publically routable IP address and a domain with DNS set up correctly.First, let's define what is traefik. It generates SSL certificates for you on the fly based on a configuration defined in a static file or dynamically using Docker networks and labels. The main advantage of this solution is that it is turnkey. This application has been specially designed to work with Docker in order to be able to detect the presence of containers in the network, read labels and automatically redirect traffic to the correct container as a load balancer.
A big disappointment for me. This problem, which may seem benign, is not. Indeed, with a very large number of certificates, we very quickly encounter a problem related to Consul : a limit of KB is applied per value.How to reset bmw computer after battery change
The only way to solve this problem was to compile a customized version of Consul in order to significantly increase this limit at the risk of losing performance by using the following patch :. This problem having been solved, several months have passed without any problems. Certificates were correctly generated, stored and served.
After this serenity, Traefik suddenly started to stop renewing certificates for some sites using HTTP I looked for where this bug could have come from, and I came across these different issues:. Using the HA part heavily, I cannot do without the Swarm currently in place, and the certificates must continue to be renewed. To date, I have not found any solution to avoid the synchronization error of the KV store Consul, Etcd Containous formally explains that the notion of HA will only be officially supported on the commercial version of Traefik.
As a result, I find myself in a dead end. I trusted a solution that no longer meets my needs, which took several days to implement.
The last two solutions seemed very complex to configure.
Caddy only partially meets these criteria. Indeed, it was not developed with a use under Docker. He didn't seem like a good candidate to me. Then, after seeing this solution come up, I asked myself a few questions : why do you hear so much about Caddy?
Now I know. Caddy was designed to work written in Go with modules, so it is fully extensible. First, Caddy can work, since version 0. This is already a very good point in order to be able to share certificates between several servers. In order to consolidate Caddy and its plugins, I decided to generate a custom Docker image, actually containing only one file excluding the CI part :.
To begin with, I migrated only one server under Caddy the one containing the most sites, obviously to test the resilience of the solution. Nothing extraordinary here, except that Caddy works, renews all certificates correctly and is fully customizable. The technique is the same between Traefik and Caddy here. The purpose of mesh routing is to point any IP to any server in the Swarm and get the response from the right container. Personally, I'm not a fan of the principle of assigning IPs only to manager nodes.
So here's the technique I use :. With this configuration, it is no longer a question of running Caddy only on the manager nodes, but on all the nodes available in the Swarm.
Since certificates are generated by only one instance of the application, we have no problem running multiple caddy instances. IPs can now be pointed to any server in the Swarm, and Caddy will forward the request to the right container even if it is not on the same server.A question can only have one accepted answer.

You can also use systemctl status caddy. It then failed and the reason it does is because of the service file configuration — specifically this line:.
NGINX functions as a proxy and web server, and it can actually do both at the same time with very minimal configuration differences between the two. NGINX can also function as a load balancer, thus it makes it very much possible to use it across the entire cluster to manage the LB, Web Server, and any proxying that you may need to do.
I actually set this up for a client I was working with about a month ago and it works very well. There is some degree of configuration needed, but it works nicely.

That gives me the impression that we can use it inside http block as SSL connection.Simple trend following strategy
But cuz of my limited knowledge on this matter, I can't see how that's potentially possible. What are your thoughts? Well the line you quoted is referring to an application outlook which wraps the RPC in HTTPS and on the other side you have another software which can handle the unpacked message. Microsoft has developed software with which packs and unpacks RDP on https traffic, of course nginx can't do this.
