How to set up an easy and secure reverse proxy with Docker, Nginx & Letsencrypt

The SSL certificate needs to contain several names, in the SubjectAltName certificate field, for example, you might want to have example. See the diff:. You may need rename the folders that letsencrypt generated. I just dont know what is configured to be the web root for my system. That folder should be generated automatically by letsencrypt.

You only need to mkdir it when doing manual SSL setup.

Very helpful!!!! To clarify one thing I had to figure out — the location of —webroot-path should be where you indiscriminately serve static files from. The cert tool will put a file in there and try to hit it to prove you own this domain. EX: your site is called mysite. This tutorial will walk you through all the necessary steps to do that. It is, however, written for setups where there is only one server block present. At the end of Step 2, a Diffie-Hellman group is generated.

Because it is shared between all server blocks, you only need to perform that step once. I know this is an old post, but if anyone comes and see it sunapi is completely correct with the certonly and the webroot commands. Hi, i had trouble with this situation. How is the server blocks for each domain? You can type! All my website with SSL encrytion were working fine.Auf Deutsch ansehen.

Last updated: Oct 18, This is accomplished by running a certificate management agent on the web server. There are two steps to this process. First, the agent proves to the CA that the web server controls a domain. Then, the agent can request, renew, and revoke certificates for that domain.

This is similar to the traditional CA process of creating an account and adding domains to that account. These are different ways that the agent can prove control of the domain. For example, the CA might give the agent a choice of either:. The agent software completes one of the provided sets of challenges. The agent also signs the provided nonce with its private key. The CA verifies the signature on the nonce, and it attempts to download the file from the web server and make sure it has the expected content.

If the signature over the nonce is valid, and the challenges check out, then the agent identified by the public key is authorized to do certificate management for example. Once the agent has an authorized key pair, requesting, renewing, and revoking certificates is simple—just send certificate management messages and sign them with the authorized key pair.

The agent also signs the whole CSR with the authorized key for example. If everything looks good, it issues a certificate for example. Revocation works in a similar manner. The agent signs a revocation request with the key pair authorized for example. If so, it publishes revocation information into the normal revocation channels i.

How It Works. Support a more secure and privacy-respecting Web.I ran into this article that offers a possible workaround to host multiple sites without a wildcard. Can anyone advise if this functionality still exists with certbot-auto? Instead, you can specify the domains on the command line when you first run certbot.

For example, you might run something like. This will request a certificate covering all of those names. When renewing the certificate with certbot-auto renewit will be replaced with a new certificate that still covers all of the names.

One more minor question… I have previously requested certs for the sites individually. What should I do to ensure that I can smoothly request updated certs? Do I need to individually revoke each one before requesting this umbrella cert? I really do appreciate your help and patience! I am a newbie to some of this. The biggest problem that I see is simply that it may be confusing to have the old certificates and the new certificates around at the same time.

If you can delete the existing certificates without breaking your web server, you might want to do that. I am a but confused about what could break, however. Would you mind providing feedback on the approach I am planning to take? I am so sorry for so many questions. This has become a high priority and I am just trying to make sure that I understand in order to avoid issues.

Are you using Apache? Were you using the Apache installer before to automatically update your Apache configurations? I think this might be the solution that I need. The only problem is, when I created the inclusive cert, it named it using one of the subdomains. Can I somehow get the cert named something other than one of the the subdomains?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. Top url you have control over customdomain. Subdomains you'd like the cert to cover comma separated, no spaces ie.

For a wildcard cert, set this exactly to wildcard wildcard cert is available via dns and duckdns validation only. Options are aliyuncloudflarecloudxnscpaneldigitaloceandnsimplednsmadeeasydomeneshopgandigoogleinwxlinodeluadnsnsoneovhrfcroute53 and transip. Optional e-mail address used for cert expiration notifications. 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.

For http validation, port 80 on the internet side of the router should be forwarded to this container's port Cloudflare provides free accounts for managing dns and is very easy to use with this image.

Due to a limitation of duckdns, the resulting cert will only cover either main subdomain ie. 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.So I decided to rehost my homepage and a couple other web pages and apps on a new server.

Hosting multiple sites or applications using Docker and NGINX reverse proxy with Letsencrypt SSL

First thing you need to run anything on the web is a server of some sort. There are all sorts of server setups available for all sorts of purposes and with all sorts of price tags. So these were the basic min specs for the server I came up with:. After researching the market a bit, I arrived at the conclusion that an entry-level VPS at a local provider here in Germany is probably what I want.

I actually used their free-tier t2.

You can run the applications under any domains or subdomains you like, provided their DNS is pointed to the server you have set up. I personally run all applications as subdomains and root domain of olex.

Hosting multiple sites or applications using Docker and NGINX reverse proxy with Letsencrypt SSL

The DNS is setup with A records for olex. Get it installed and configured as you would configure any Internet-facing server - SSH with public key auth only, no root login, fail2ban, the usual setup.

Important thing is at the end you have a working server with Docker and Compose available. Its job is to listen on external ports 80 and and connect requests to corresponding Docker containers, without exposing their inner workings or ports directly to the outside world. My docker-compose. Its ports 80 and are forwarded to the host, making it Internet-facing. Various NGINX configuration directories are mounted as named volumes to keep them persistent on the host system. Those volumes are defined further down in the file.

This allows the proxy to listen in to other containers starting and stopping on the host, and configure NGINX forwarding as needed. Containers need to present their desired hostnames and ports as environment variables that the proxy can read - more on that further below. Finally, the container is assigned to a proxy external network, which is described below. To understand why you might need it, you need to know how docker-compose handles networks by default:.

For every application that is run using its own docker-compose. All containers within that application are assigned only to that network, and can talk to each other and to the Internet. We want to deploy multiple applications on this server using Compose, each with their own docker-compose. This makes life difficult for nginx-proxy. To do this, we need to define this network as external in the docker-compose.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

The LinuxServer. Letsencrypt sets up an Nginx webserver and reverse proxy with php support and a built-in letsencrypt client that automates free SSL server certificate generation and renewal processes. It also contains fail2ban for intrusion prevention.

Most of our images are static, versioned, and require an image update and container recreation to update the app inside. With some exceptions ie. Please consult the Application Setup section above to see if it is recommended for the image. Note: We do not endorse the use of Watchtower as a solution to automated updates of existing Docker containers.

In fact we generally discourage automated updates. However, this is a useful tool for one-time manual updates of containers where you have forgotten the original parameters. In the long term, we highly recommend using Docker Compose. If you want to make local modifications to these images for development purposes or just to customize the logic:.

This is the only publicly exposed container, routes traffic to the backend servers and provides TLS termination.

It is defined in docker-compose. When a new container is spinning up this container detects that, generates the appropriate configuration entries and restarts Nginx.

The container reads the nginx. Security warning : mounting the Docker socket is usually discouraged because the container getting even read-only access to it can get root access to the host. In our case, this container is not exposed to the world so if you trust the code running inside it the risks are probably fairly low. But definitely something to take into account. See e. The Dangers of Docker. NOTE: it would be preferrable to have docker-gen only handle containers with exposed ports via -only-exposed flag in the entrypoint script above but currently that does not work, see e.

At regular intervals it checks and renews certificates as needed. The container uses a volume shared with the host and the Nginx container to maintain the certificates. It also mounts the Docker socket in order to inspect the other containers. See the security warning above in the docker-gen section about the risks of that. These two very simple samples are running in their own respective containers. They are defined in docker-compose. The important part here are the environment variables.

These are used by the config generator and certificate maintainer containers to set up the system. The source code for these two images is in the samples subfolder, the images are built from there. In a real-world scenario these images would likely come from a Docker registry.
