Elasticbeanstalk Customize Nginx through ebextension

I have been literally all day fighting with this, I just need to increase the client_max_body_size in my Nginx Configuration.

I have a tomcat configuration (custom ami) and I tried this so far.

• creating a file in /etc/nginx/conf.d/my-http.conf
• creating a file in /tmp and then move it to the above location
• creating the filesystem in my source code
  .ebextensions/nginx/conf.d/my-http.conf

Here is the latest (desperate) file I tested (named .ebextensions/http_conf.config)

files:
  "/tmp/http.conf.tmp" :
    mode: "000644"
    owner: root
    group: root
    content: |
      client_max_body_size 10M;

  "/etc/nginx/conf.d/proxy.conf":
    mode: "000755"
    owner: root
    group: root
    content: |
      client_max_body_size 20M;      

container_commands:
  01_remove_current_http_conf:
    command: "rm -f /etc/nginx/conf.d/http.conf"
  02_cp_new_http_conf:
    command: "cp /tmp/http.conf.tmp /tmp/http.conf.tmp2"
  03_cp_new_http_conf2:
    command: "cp /tmp/http.conf.tmp /etc/nginx/conf.d/http.conf"

So as you can see, I’m trying everything, let me share the results of this.

• I can see a file created at /tmp/http.conf.tmp
• I can’t see a file created at /etc/nginx/conf.d/proxy.conf
• I can see a file created at /tmp/http.conf.tmp2
• I can’t see a file created at /etc/nginx/conf.d/http.conf

I’m guessing the directory is overwritten after I create those files somehow, but I couldn’t find a way to avoid that.
