How to configure a reverse proxy for Artifactory Docker repository when using AWS-ELB load balancer?

Here is a basic example of the configuration file for a NGINX reverse proxy.

Port 80 is used only as a reference in this example. It is the port the AWS-ELB set for Artifactory.

This configuration uses LUA module (the section with it is marked in bold). It is recommended to use it, although it is not mandatory.

server {

    listen 80;

    server_tokens off;

    ####Server name #####

    server_name <my.artifactory.com>;

    client_max_body_size 0;

   ## Application specific logs

   ## access_log /var/log/nginx/my.artifactory.com-access.log;

   ## error_log /var/log/nginx/my.artifactory.com-error.log;



    location ~* ^/(402\.htm|500\.htm|502\.htm|503\.htm|503-migrate\.htm)$ {

        root /usr/share/nginx/html;

    }



    if ($http_x_forwarded_proto != "https") {

        rewrite ^/artifactory/webapp/(.*) https://$host/artifactory/webapp/$1 redirect;

        rewrite ^/$ $scheme://$host/artifactory/webapp/#/home redirect;

    }

    if ($http_x_forwarded_proto = "https") {

        rewrite ^/$ https://$host/artifactory/webapp/#/home redirect;

    }

   #### docker repository name #####

    rewrite ^/(v1|v2)/(.*) /artifactory/api/docker/<docker-repo-name>/$1/$2;



header_filter_by_lua '

    local myProto = ngx.var["http_x_forwarded_proto"]

    if myProto == "https" then

        local locHeader = ngx.header["Location"]

        if locHeader then

            if type(locHeader) == "string" then

                local location = ngx.re.match(locHeader, "http[s]?://(.*)", "io")

                if location then

                    ngx.header["Location"] = "https://" .. location[1]

                end

            end

        end

    end

';
