The reverse proxy. One of those projects you put off for years but when you finally get to it you find that it was relatively simple all along. We can't hope to cover everything relating to such a broad topic in one article but we'll use an nginx based reverse proxy to get you started. Below, we detail how to expose certain services using the LinuxServer.

We'll cover a few basic apps, including Plex, and provide example configurations along the way leaving the rest up to you, the community to post examples in the comments, as a Github gist or over on our new Discord server. All the files required for this article are available on Github here. Always a good question to ask before investing your time into a project. In this case there are several answers Over the last few years there have been some very useful tools created to make this process so simple that there's no good excuse not to do it now!

I am of course talking primarily about Let's Encrypt, a free SSL certificate provider - something for which you previously had to pay real space bucks to obtain.

Then there's docker, which makes encapsulating applications as easy as its ever been. We'll combine the two to create our solution in this article.

During the setup process your web server must be publicly accessible so that Let's Encrypt can perform validation but you might not always want that to be the case. In fact, I'd probably suggest mixing this with a VPN for proper security anyway. Brute forcing HTTP passwords isn't unheard of and you'll still get all the benefits of the reverse proxy except your URLs won't be publicly available. That's a topic for another article entirely, though.

How to Enable HTTPS on your Docker Application

A reverse proxy is a type of proxy server that retrieves resources on behalf of a client from one or more servers. These resources are then returned to the client as if they originated from the Web server itself. Let's take nginx itself as an example here. Nginx is a simple web server. You can go run it on your system in a few seconds with docker.The downside will be that every user that remotely accesses your NAS will be greeted with the above message unless they manually add the certificate to their browser's approved SSL provider list.

COM -- ex. The DDNS is a subdomain. Let's say you signed up and registered this subdomain on freeDNS: loki. In laymans terms: loki. Once you've set up a DDNS, you'll want to go to your router settings and find the port forward option. You'll want to forward the following ports:. To test if the ports have been forwarded, use this website: Can You See Me. Test all ports listed above. If they all register as open, continue to step 3. Log in to your Synology NAS.

If you get an error about maximum certificates, then you'll need to chose another domain. If all goes well, you'll see a new certificate listed under the "Certificate" tab. Click on the certificate to select it, then click Configure. Make sure that the System default is using this certificate.

Your browser URL bar should now show:. Make a directory called certs inside of the gitlab data folder. For example very important that this folder is inside the gitlab data folder! Use the commands below to copy the Let's Encrypt files into your gitlab's certs directory. Then connect via "Site Manager" dropdown located underneath "File". Results both NAS and Gitlab secured by one cert :.

I'm in the process of building a validate SSL certs script that aims to automate the certificate renewal process, so stay tuned.

How to setup a reverse proxy with LetsEncrypt SSL for all your Docker apps

LetsEncrypt certificate will be auto generated and stored in the host dir as letsencrypt. You could also use a Docker volume to store it. In order for the certificate generation to work the registry needs to be accessible from the internet in port You can also create a config. If you want to use this as a remote repository and not just for proxying, remove the proxy entry in the configuration.

I am running an Express -based website in a Docker container based on the Node. How do I use Let's Encrypt with a container based on that image? I am using the following app. I also ended up with the following packages. Here's the output when I do my docker build step. I've removed most of the npm install output for brevity sake:.

Now, I've got my very basic express-based website running in a Docker container, but it doesn't yet have any TLS set up. Looking again at the expressjs docs, the security best practice when using TLS is to use nginx. Since nginx will need some certificates to work with, let's go ahead and generate those with the letsencrypt client.

Run the following commands to generate the initial certificates. You'll also need to have your DNS name set up and pointing to the box that you run this on:. The email address is used for expiration notifications.

Now, let's set up an nginx server that will make use of this newly generated certificate. First, we'll need an nginx config file that is configured for TLS:. Next, we'll create a custom network so we can take advantage of Docker's service discovery feature:. Double check that nginx came up properly by taking a look at the output of docker logs expressnginx. The nginx config file should redirect any requests on port 80 over to port We can test that by running the following:. Now, to set up the renewal process.

The nginx. If you run the following command, it will handle renewal. Normally, you'll run this command on some sort of cron so that your certs will be renewed before they expire:.

There are many ways to achieve this depending on your setup. One popular way is to setup nginx in front of your Docker container, and handle the certificates entirely within your nginx config. The nginx config can contain a list of 'usptreams' your Docker containers and 'servers' which essentially map requests to particular upstreams.It also contains fail2ban for intrusion prevention.

Our images support multiple architectures such as xarm64 and armhf. We utilise the docker manifest for multi-platform awareness. More information is available from docker here and our announcement here. The architectures supported by this image are:. Here are some example snippets to help you get started creating a container from this image.

Compatible with docker-compose v2 schemas. Docker images are configured using parameters passed at runtime such as those above. For example, -p would expose port 80 from inside the container to be accessible from the host's IP on port outside the container.

Https port. Http port required for http validation only.

If you wish to get certs only for certain subdomains, but not the main domain main domain may be hosted on another machine and cannot be validatedset this to true. Additional fully qualified domain names comma separated, no spaces ie. Set to true to retrieve certs in staging mode. Rate limits will be much higher, but the resulting cert will not pass the browser's security test. Only to be used for testing purposes. All the config files including the webroot reside here.

Ensure any volume directories on the host are owned by the same user you specify and any permissions issues will vanish like magic.

You can use our duckdns image to update your IP on duckdns. If you need a dynamic dns provider, you can use the free provider duckdns. Certs are checked nightly and if expiration is within 30 days, renewal is attempted. It is recommended to input your e-mail in docker parameters so you receive expiration notices from letsencrypt in those circumstances. Security and password protection. The container detects changes to url and subdomains, revokes existing certs and generates new ones during start.

If you'd like to password protect your sites, you can use htpasswd.

You can add multiple user:pass to. For the first user, use the above command, for others, use the above command without the -c flag, as it will force deletion of the existing. You can also use ldap auth for security and access control.Supported architectures : more info amd64arm32v6arm32v7arm64v8ippc64lesx. The nginx project started with a strong focus on high concurrency, high performance and low memory usage. It also has a proof of concept port for Microsoft Windows.

Alternatively, a simple Dockerfile can be used to generate a new image that includes the necessary content which is a much cleaner solution than the bind mount above :. Place this file in the same directory as your directory of content "static-html-directory"run docker build -t some-content-nginx.

For information on the syntax of the nginx configuration files, see the official documentation specifically the Beginner's Guide.

If you wish to adapt the default configuration, use something like the following to copy it from a running nginx container:. If you add a custom CMD in the Dockerfile, be sure to include -g daemon off; in the CMD in order for nginx to stay in the foreground, so that Docker can track the process properly otherwise your container will stop immediately after starting!

Out-of-the-box, nginx doesn't support environment variables inside most configuration blocks. But envsubst may be used as a workaround if you need to generate your nginx configuration dynamically before nginx starts.

To run nginx in read-only mode, you will need to mount a Docker volume to every location where nginx writes information. This can be easily accomplished by running nginx as follows:. If you have a more advanced configuration that requires nginx to write to other locations, simply add more volume mounts to those locations.

Images since version 1. It can be used with simple CMD substitution:. Since 1. Amplify is a free monitoring tool that can be used to monitor microservice architectures based on nginx.

Amplify is developed and maintained by the company behind the nginx software. With Amplify it is possible to collect and aggregate metrics across containers, and present a coherent set of visualizations of the key performance data, such as active connections or requests per second.

It is also easy to quickly check for any performance degradations, traffic anomalies, and get a deeper insight into the nginx configuration in general. In order to use Amplify, a small Python-based agent software Amplify Agent should be installed inside the container. For more information about Amplify, please check the official documentation here.

This is the defacto image. If you are unsure about what your needs are, you probably want to use this one. It is designed to be used both as a throw away container mount your source code and start the container to start your appas well as the base to build other images off of.

This image is based on the popular Alpine Linux projectavailable in the alpine official image. This variant is highly recommended when final image size being as small as possible is desired. The main caveat to note is that it does use musl libc instead of glibc and friendsso certain software might run into issues depending on the depth of their libc requirements.

However, most software doesn't have an issue with this, so this variant is usually a very safe choice. To minimize image size, it's uncommon for additional related tools such as git or bash to be included in Alpine-based images. Using this image as a base, add the things you need in your own Dockerfile see the alpine image description for examples of how to install packages if you are unfamiliar.

View license information for the software contained in this image. As with all Docker images, these likely also contain other software which may be under other licenses such as Bash, etc from the base distribution, along with any direct or indirect dependencies of the primary software being contained. As for any pre-built image usage, it is the image user's responsibility to ensure that any use of this image complies with any relevant licenses for all software contained within.
