# generating config with templates

configuration:

```nginx
{%- import 'snip/cache.j2mod' as _cache -%}

{%- set my_caches = (j2cfg.my_caches or []) -%}

{%- for h in my_caches %}
{{ _cache.proxy_cache_path(h.name, size='10m', levels='1:2', inactive=h.max_time) }}
{%- endfor %}

server {
    listen 8888;

    location / { return 204; }

    {%- for h in my_caches %}
    location /{{ h.name }}/ {
        proxy_pass {{ h.uri }}/;

        proxy_cache  {{ h.name }};

        expires {{ h.valid_time }};

        proxy_cache_valid 200 {{ h.valid_time }};
        proxy_cache_valid any 30s;
    }
    {%- endfor %}
}
```

site configuration (via `j2cfg/my-caches.yml`):

```yml
my_caches:

  - name: apt_debian
    uri: https://deb.debian.org/debian
    valid_time: 180m
    max_time: 1440h

  - name: apt_debian_security
    uri: https://deb.debian.org/debian-security
    valid_time: 180m
    max_time: 1440h

## and so on ...
```

---

docker-compose.yml:

```yml
version: "3.8"

services:

  angie-conv-example-config-template:
    container_name: angie-conv-example-config-template
    image: docker.io/rockdrilla/angie-conv:v0.0.1
    restart: always
    privileged: true
    stop_grace_period: 15s
    network_mode: host
    environment:
      NGX_HTTP_TRANSPARENT_PROXY: 1
    volumes:
      - "./conf:/etc/angie:ro"
      - "./data:/angie"
```

---

final configuration looks like this:

```nginx
proxy_cache_path  /run/ngx/cache/proxy_apt_debian
  keys_zone=apt_debian:10m:file=/run/ngx/lib/proxy_apt_debian.keys
  inactive=1440h
  levels=1:2
;

# ...

server {
# ...

    location /apt_debian/ {
        proxy_pass https://deb.debian.org/debian/;

        proxy_cache  apt_debian;

        expires 180m;

        proxy_cache_valid 200 180m;
        proxy_cache_valid any 30s;
    }

# ...
}
```

```sh
curl -v http://localhost:8888/apt_debian/dists/bookworm/main/binary-all/Release
