# Шиблоны
|
|||
|
|
|||
|
Шаблоны для Surok пишутся на Jinja2. Возможно, стоит прочитать документацию.
|
|||
|
|
|||
|
## Словарь my в шаблоне
|
|||
|
|
|||
|
Surok заполняет словарь my и передает его в шаблон.
|
|||
|
```
|
|||
|
{
|
|||
|
"services": {
|
|||
|
"nginx": [
|
|||
|
{
|
|||
|
"name": "nginx.testing-kl92-s0.marathon.mesos.",
|
|||
|
"port": "31200"
|
|||
|
},
|
|||
|
{
|
|||
|
"name": "nginx.testing-kl123-s1.marathon.mesos.",
|
|||
|
"port": "32230"
|
|||
|
}
|
|||
|
],
|
|||
|
"emailsender": [
|
|||
|
{
|
|||
|
"name": "emailsender.testing-kl92-s0.marathon.mesos.",
|
|||
|
"port": "31201"
|
|||
|
},
|
|||
|
{
|
|||
|
"name": "emailsender.testing-kl123-s1.marathon.mesos.",
|
|||
|
"port": "32232"
|
|||
|
}
|
|||
|
],
|
|||
|
"service-with-defined-ports": {
|
|||
|
"web": [
|
|||
|
{
|
|||
|
"name": "f.q.d.n",
|
|||
|
"port": 12341
|
|||
|
}
|
|||
|
],
|
|||
|
"rpc": [
|
|||
|
{
|
|||
|
"name": "f.q.d.n",
|
|||
|
"port": 12342
|
|||
|
}
|
|||
|
]
|
|||
|
}
|
|||
|
},
|
|||
|
"env": {
|
|||
|
"HOME": "/var/lib/nginx"
|
|||
|
}
|
|||
|
}
|
|||
|
```
|
|||
|
|
|||
|
## Пример реального шаблона
|
|||
|
|
|||
|
```
|
|||
|
upstream matrix-http {
|
|||
|
hash $remote_addr;
|
|||
|
{% for server in my['services']['matrix']['http'] %}
|
|||
|
server {{server['name']}}:{{server['port']}} max_fails=3;
|
|||
|
{% endfor %}
|
|||
|
}
|
|||
|
|
|||
|
upstream riot-http {
|
|||
|
hash $remote_addr;
|
|||
|
{% for server in my['services']['riot'] %}
|
|||
|
server {{server['name']}}:{{server['port']}} max_fails=3;
|
|||
|
{% endfor %}
|
|||
|
}
|
|||
|
|
|||
|
server {
|
|||
|
listen 10.15.56.157:80;
|
|||
|
server_name matrix.example.com;
|
|||
|
|
|||
|
client_max_body_size 10m;
|
|||
|
|
|||
|
location / {
|
|||
|
proxy_pass http://riot-http;
|
|||
|
proxy_set_header X-Real-IP $remote_addr;
|
|||
|
proxy_set_header Host $http_host;
|
|||
|
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
|
|||
|
}
|
|||
|
|
|||
|
location /_matrix/ {
|
|||
|
proxy_pass http://matrix-http;
|
|||
|
proxy_set_header X-Real-IP $remote_addr;
|
|||
|
proxy_set_header Host $http_host;
|
|||
|
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
|
|||
|
}
|
|||
|
|
|||
|
}
|
|||
|
```
|
|||
|
Так для upstream matrix-http используются именованные порты, а для riot-http – нет.
|
|||
|
|
|||
|
## Проверки в шаблоне
|
|||
|
|
|||
|
Переменная _my['env']_ является классом python _os.environ_, что позваоляет нам строить различные проверки, например:
|
|||
|
|
|||
|
```
|
|||
|
{% if my['env'].get('DB_HOST') %}
|
|||
|
host = '{{my['env']['DB_HOST']}}'
|
|||
|
{% else %}
|
|||
|
host = 'localhost'
|
|||
|
{% endif %}
|
|||
|
```
|
|||
