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.
Docker + Nginx + Let's Encrypt
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.
Thank you for your Doc. You have to create it.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.First and foremost, this whole blog idea is just a way for me to easily find this info again, in case I need it. Secondly, hopefully this info helps you out too, in case you want to have a valid SSL certificate for your Unifi Controller.
Which is running in a Docker container. On your Synology NAS. The command below will request the first certificate and create a configuration file for acme. The —pre-hook command will run each time the certificate is renewed. In this case it will create a backup of the Unifi configuration backups and the keystore. The acme. The —fullchainpath and —keypath parameters copy the certificate and key files to the specified paths. I got my inspiration from naschenweng. Your email address will not be published.
I guess the topic perfectly describes what this post is about. The actual and useful info starts here. These instructions might work with other images, just make sure the path to the keystore is correct. You need to install the Java8 package on your Synology. It contains the important keytool command. Without it, you can skip reading the rest of this post.
If not, check out this post. Start by creating the following script. Run the command to issue the certificate for the first time.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.
Set up a reverse proxy Nginx and Docker-gen (Bonus: Let's Encrypt)
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. 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. If you want nginx to be visible to the outside world you will need to start doing port forwarding on your firewall.Today, we continue our blog post series about Docker and I would like to show you how to access your containers through your domain.
Furthermore this is a great use case for Docker Compose :. Let's move to the heart of the solution: nginx-proxy. Nginx-proxy is a Docker image based on the famous web server Nginx and docker-gen, a tool using the container's environment variables to generate virtual host configurations and automatically apply them to Nginx. So that docker-gen receives the Docker daemon's events, we have to add a volume for the socket.
The second volume allows you to add your own configurations to the generated virtual hosts. The last step is to add some environment variables to our Owncloud container. With them, docker-gen knows it has to generate a virtual host linked to our subdomain:. To finish Owncloud 's configuration, you can use the Mysql service's hostname which will be automatically resolved by Docker's DNS:.
As we saw, Nginx-proxy with Docker-gen is a nice solution for a reverse proxy for your containers. Its strength comes from its simplicity combined with Nginx 's robustness.
You are now able to bootstrap a simple Docker architecture with Docker Compose and use it with your own domain. With the help of the letsencrypt-nginx-proxy-companion image, your certificates will be automatically created and renewed. Let's Encrypt uses a per week rate limit on generated certificates and, for that reason, you should store them in a volume so that they will not be generated at each start!
Let's start by adding to our nginx-proxy container the volumes where there will be stored files about certificates --created by letsencrypt-nginx-proxy-companion -- and a label used by letsencrypt-nginx-proxy-companion to find nginx-proxy:.
Notice that we are, now, also exposing port We are here using the same volumes defined in the nginx-proxy service but we are allowing letsencrypt-nginx-proxy-companion to write certificates. The last step is to add some environment variables to our Owncloud container so that letsencrypt-nginx-proxy-companion will generate the certificates and the HTTPS configuration for us:. Replace [your-sub-domain] by the value you would like to use then start the stack, you will then be entitled to a beautiful green https:.

Nginx Proxy Manager enables you to easily forward to your websites running at home or otherwise, including free SSL, without having to know too much about Nginx or Letsencrypt. NOTE : The Docker command provided in this quick start is given as an example and parameters should be adjusted to your need. To customize some properties of the container, the following environment variables can be passed via the -e parameter one for each variable.
The following table describes data volumes used by the container. The mappings are set via the -v parameter. Here is the list of ports used by the container. They can be mapped to the host via the -p parameter one per port mapping. The port number inside the container cannot be changed, but you are free to use any port on the host side. As seen, environment variables, volume mappings and port mappings are specified while creating the container. The following steps describe the method used to add, remove or update parameter s of an existing container.
The generic idea is to destroy and re-create the container:. Here is an example of a docker-compose. Make sure to adjust according to your needs. Note that only mandatory network ports are part of the example. If the system on which the container runs doesn't provide a way to easily update the Docker image, the following steps can be followed:.
When using data volumes -v flagspermissions issues can occur between the host and the container. For example, the user within the container may not exists on the host. This could prevent the host from properly accessing files and folders on the shared volume.
To find the right IDs to use, issue the following command on the host, with the user owning the data volume on the host:. The value of uid user ID and gid group ID are the ones that you should be given the container. Assuming that container's ports are mapped to the same host's ports, the interface of the application can be accessed with a web browser at:. After you login with this default user, you will be asked to modify your details and change your password.
NOTE: This section assumes that the container is using the default bridge network type.
