Setup Gogs with HTTPS

There are two ways to use HTTPS for Gogs based on the way you choose to deploy:

  1. Reverse proxy, e.g. NGINX, Caddy
  2. Expose Gogs on the internet directly

And there are two types of HTTPS certificates: real and pretend to be real.

So, let’s talk about how to get your HTTPS certificates.

Obtain HTTPS Certificates

  1. Buy business version (OH PLEASE!!! Donate a million or two to Gogs project ๐Ÿ˜Š)
  2. Apply free version from Let’s Encrypt or StartSSL
  3. Self-signed

You can Google (I just happened to be lazy) about how to get the first two versions of certificates. There are also some tools can generate self-signed certificates, but in this article, I’m going to talk about how to use Gogs to generate them.

First of all, you have to build Gogs with build tags cert (official binaries are included this tag by default).

After that, execute the following command is all you need:

$ ./gogs cert -ca=true -duration=8760h0m0s

Don’t forget to replace with your own domain (Wait, did you just say that you DO NOT OWN ONE? Go buy it!)

OK, now you should have two new files in the current directory: cert.pem and key.pem.

Config HTTPS Certificates

I’ve mentioned that there are two ways to config HTTPS for Gogs.

If you’re using reverse proxy, all you need to do on Gogs’s configuration is making sure your ROOT_URL is using a HTTPS URL, such as, and


For NGINX, see example below:

server {
    listen 443 ssl;
    ssl_certificate path/to/cert.pem;
    ssl_certificate_key path/to/key.pem;

    location / {
        proxy_set_header  X-Real-IP  $remote_addr;
        proxy_pass http://localhost:3000$request_uri;

# Redirect HTTP requests to HTTPS
server {
    listen 80;
    return 301 https://$host$request_uri;

Look at it! Gogs still starts as normal HTTP! Let NGINX do all the dirty works!!!

Maybe I’m not so clear, but I believe you get the point…

Great, see how to do the same thing with Caddy: {
    proxy / localhost:3001
    tls path/to/cert.pem path/to/key.pem

# Redirect HTTP requests to HTTPS {
    redir{uri} 301

It’s so damn obvious in Caddy!

Of course, I’m not saying expose Gogs directly on the internet is bad, you have your ways of doing things. Then, change the following configuration in your custom app.ini file:

PROTOCOL = https
CERT_FILE = path/to/cert.pem
KEY_FILE = path/to/key.pem

(I have to say Gogs itself has the least lines of configuration ๐Ÿ˜‚)

Well done!

If you’re using real certificates, a green nice locker will show near the URL bar in Chrome. Otherwise, an ugly red sad face is taking the place.
