README.md

Add the attached script to the .ebextensions folder in the deployment package to enable gzip compression on the nginx proxy. This compresses text payloads such as HTML, Javascript and JSON for a better client experience. Works for Elastic Beanstalk with single-container Docker. Some EB stacks allow the choice between Apache httpd and nginx so it will not for all EB configurations.

I still couldn't get this to work, I got this:

Command failed on instance. Return code: 127 Output: /bin/sh: service: command not found. container_command 02_restart_nginx in travis-03f3fd2dc94f868fdec1f1db00024asdf9c2311d93-1486642650/.ebextensions/02_nginx_gzip.config failed. For more detail, check /var/log/eb-activity.log using console or EB CLI.

And then in eb-activity log

Activity execution failed, because: /bin/sh: service: command not found

I'm inspecting it more tomorrow

It seems like on line 11, the text/html is not needed as it is compressed by default, and nginx will give warnings for duplication and it stops deployment.

I fixed my issues with this config:

Looks like Elasticbeanstalk now has gzip enabled by default:

/etc/nginx/sites-available/elasticbeanstalk-nginx-docker-proxy.conf

map $http_upgrade $connection_upgrade {
        default        "upgrade";
        ""            "";
    }

    server {
        listen 80;

        gzip on;
            gzip_comp_level 4;
            gzip_types text/html text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript;



        access_log    /var/log/nginx/access.log;

        location / {
            proxy_pass            http://docker;
            proxy_http_version    1.1;

            proxy_set_header    Connection            $connection_upgrade;
            proxy_set_header    Upgrade                $http_upgrade;
            proxy_set_header    Host                $host;
            proxy_set_header    X-Real-IP            $remote_addr;
            proxy_set_header    X-Forwarded-For        $proxy_add_x_forwarded_for;
        }
    }
