# generating config with templates

configuration:

```nginx
{%- for h in (j2cfg.my_caches or []) %}
proxy_cache_path
    /angie/my-cache/{{ h.name }}
    keys_zone={{ h.name }}:20m
    levels=1:2 inactive={{ h.max_time }};
{%- endfor %}

server {
    listen 8888;

    location / { return 204; }

    {%- for h in (j2cfg.my_caches or []) %}
    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: proxy_apt_debian
    uri: https://deb.debian.org/debian
    valid_time: 180m
    max_time: 1440h
  - name: proxy_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:

  my-cache:
    container_name: my-cache
    image: docker.io/rockdrilla/angie-conv:v0.0.5
    restart: always
    privileged: true
    stop_grace_period: 15s
    network_mode: host
    volumes:
      - "./conf/image-entry:/image-entry:ro"
      - "./conf/j2cfg:/angie/j2cfg:ro"
      - "./conf/site:/angie/site:ro"
      - "./cache:/angie/my-cache"
```

---

final configuration looks like this:

```nginx
proxy_cache_path
    /angie/my-cache/proxy_apt_debian
    keys_zone=proxy_apt_debian:20m
    levels=1:2 inactive=1440h;

# ...

server {
# ...

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

        proxy_cache  proxy_apt_debian;

        expires 180m;

        proxy_cache_valid 200 180m;
        proxy_cache_valid any 30s;
    }

# ...
}
```
