Add an option to extend an apps frontend and backend definition

[Laures]

currently the only way to add settings to an apps frontend or backend definition is to overwrite an existing template by copy/pasting its current content and add whatever option is required.

this results in an overly complex marathon config and is not very save, as templates might change in the future.

as an option there could be a template (for example: HAPROXY_{0}_BACKEND_ADDITION) that is empty by default and is added to the backend definition of the app.

Excuse me please! I have the problem. example: Default template for HAPROXY_HTTP_BACKEND_REDIR:

acl is_root path -i / acl is_domain hdr(host) -i {hostname} redirect code 301 location {redirpath} if is_domain is_root

then I want to modify like this

acl is_my_root path -i {my_path} acl is_my_domain hdr(host) -i {my_hostname} redirect code 301 location {redirpath} if is_my_domain is_my_root

how ?
if couldn't maybe I will modify source code.but i am not good at python. @brndnmtthws

I have found the way to solve my problem.

Use HAPROXY_0_BACKEND_HTTP_OPTIONS to override, like this:

"HAPROXY_GROUP": "my_group", "HAPROXY_0_BACKEND_HTTP_OPTIONS": " option forwardfor\n http-request set-header X-Forwarded-Port %[dst_port]\n http-request add-header X-Forwarded-Proto https if { ssl_fc }\n acl is_my_rewrite_domain hdr(host) -i my_rewrite_domain\n reqrep ^([^\\ ]*)\\ /my-path(.*) \\1\\ /my-path/api\\2 if is_my_rewrite_domain\n", "HAPROXY_0_PATH": "-i /my-path", "HAPROXY_0_VHOST": "my_domain,my_rewrite_domain"

Then in backend will replace the path.
