servercontainers/nginx repository overview

⁠Docker production ready NGINX Container (servercontainers/nginx)

maintained by ServerContainers

⁠Versioning

You'll find all images tagged like d11.2-ne1.18.0-6.1 which means d<debian version>-ne<nginx-extras version (with some esacped chars)>. This way you can pin your installation/configuration to a certian version. or easily roll back if you experience any problems (don't forget to open a issue in that case ;D).

The latest version will be updated/released after I managed to test a new pinned version in my production environment. This way I can easily find and fix bugs without affecting any users. It will result in a way more stable container.

⁠What is it

This Dockerfile (available as servercontainers/nginx) gives you a NGINX on alpine. It also generates self signed certificates and reverse proxy mechanism.

It uses debian package nginx-extras.

For Configuration of the Server you use environment Variables.

It's based on the debian:bullseye⁠ Image

View in Docker Registry servercontainers/nginx⁠

View in GitHub ServerContainers/nginx⁠

⁠Usage

You can try this container with the provided docker_compose.yml which starts an mysql container with phpmyadmin and adds a reverse proxy location to the nginx.

So you can open the phpmyadmin SSL protected at https://localhost/phpmyadmin/⁠

⁠Environment variables and defaults

⁠NGINX

All options for the OpenSSL Stuff

• NGINX_CONFIG_myconfigname
  • multiple variables/confgurations possible by adding unique configname to NGINX_CONFIG_
  • adds a new nginx configuration
  • server_name is required
  • example:
    • "server {server_name localhost; location / {root /data; index index.html;}}"
  • by default http redirects to ssl, ssl options get injected

to get an a+ rating at the qualys ssl test you need to set the Strict-Transport-Security inside your nginx configuration like this:

# only this domain
add_header Strict-Transport-Security "max-age=31536000";
# apply also on subdomains
add_header Strict-Transport-Security "max-age=31536000; includeSubdomains";

• NGINX_HTTP_ACTION

  • only works with NGINX_CONFIG_ configurations
  • default value location / {return 301 https://$SERVER_NAME;}
  • changes default behavior of always redirect http to https

• NGINX_HTTP_ACTION_myconfigname

  • only works for corresponding NGINX_CONFIG_myconfigname configuration
  • default value location / {return 301 https://$SERVER_NAME;}
  • overwrites global NGINX_HTTP_ACTION
  • changes default behavior of always redirect http to https

• NGINX_RAW_CONFIG_myconfigname

  • multiple variables/confgurations possible by adding unique configname to NGINX_RAW_CONFIG_
  • adds a new nginx configuration without any modification
  • example:
    • "server {listen 80; listen [::]:80; server_name example.com; return 301 https://www.example.com;}⁠"

⁠HTACCESS

• HTACCESS_ACCOUNT_username
  • multiple variables/accounts possible
  • adds a new htaccess account with the given username and the env value as password (SHA-512 Hashed)
  • password can be a hash created with mkpasswd e.g. created with mkpasswd -m sha-512 (escape $ with $$ in docker-compose.yml)
  • htaccess file will be saved at /conf/auth.htpasswd

to enable authentication add the following to your nginx config (inside or outside the location tag):

auth_basic "Restricted Area"; auth_basic_user_file /conf/auth.htpasswd;

⁠OpenSSL

All options for the OpenSSL Stuff

• DH_SIZE
  • no default - needed only if you don't trust my shipped 2048 version.
  • if set a new one with given size is generated
  • only use a number as value

⁠Specials

⁠Docker Registry proxy with Basic Auth

You can indeed use this container as a Docker Registry Proxy with Basic Authentication. Just add some Accounts with the HTACCESS_ACCOUNT_username variables and take a look at the following NGINX_CONFIG_myconfigname configuration.

HTACCESS_ACCOUNT_marvin=MyRegistRyPasSwOrD
NGINX_CONFIG_myDockerRegistry="upstream docker-registry {server registry:5000;} server {server_name registry.example.com; include /etc/nginx/snippets/docker-registry-proxy.conf;}"

You need to specify the docker registry upstream, add a server_name necessary for the certificate generation. Most importantly include the file include /etc/nginx/snippets/docker-registry-proxy.conf; inside your server statement.

Thats all - now you have a working docker registry proxy with ssl, basic auth!

⁠NGINX WebDav Server

To get a WebDav Server with MacOS Support and everything, just use the following configuration with snipped.

    HTACCESS_ACCOUNT_marvin=MyWebDavPassword
    NGINX_CONFIG_webdavServer="server {server_name webdav.example.com; location / { auth_basic "Restricted"; auth_basic_user_file /conf/auth.htpasswd; include /etc/nginx/snippets/webdav-server.conf;} }"
