AWS Elastic Beanstalk: nginx reload failed

Question

I have provided to my Elastic Beanstalk environment nginx configuration according to this article. My application sits in a Docker container. The problem is that the environment fails to reload nginx.

Here's my config file:

files:
  "/etc/nginx/conf.d/proxy.conf" :
    mode: "000644"
    owner: root
    group: root
    content: |
      client_max_body_size 500M;

container_commands:
  01_reload_nginx:
    command: "sudo service nginx reload"

And that results in failure (after /var/log/eb-activity.log):

  Application deployment - Command CMD-Startup failed

When I remove section:

container_commands:
  01_reload_nginx:
    command: "sudo service nginx reload"

Deployment goes smooth.

Any ideas? How can I get information on what precisely goes wrong with the command? If I ssh to my instance, I can execute command without a problem.

The elastic beanstalk deployment process will do the nginx reload for you, so you can remove it from your script permanently and avoid the error. Figuring out why exactly the command failed will just be academic
