Recentemente ho cambiato il server virtuale e ho dovuto configurare tutto da capo. Preferisco che il sito sia accessibile tramite https e che i certificati letsencrypt siano ottenuti e rinnovati automaticamente. Questo pu\u00f2 essere realizzato utilizzando due immagini docker: nginx-proxy e nginx-proxy-companion.<\/p>\n

<\/p>\n

Questa guida spiega come configurare un sito su docker, con un proxy che ottiene automaticamente Certificati SSL<\/a>. Si utilizza un server virtuale CentOS 7.<\/p>\n

<\/a><\/noindex><\/p>\n

Presumo che il server sia gi\u00e0 stato acquistato, configurato, l'accesso avvenga tramite chiave, e che sia stato installato fail2ban, ecc.<\/p>\n

<\/p>\n

Per iniziare, \u00e8 necessario installare docker.<\/p>\n

<\/p>\n

    \n
  1. Per prima cosa \u00e8 necessario installare le dipendenze\n
    $ sudo yum install -y yum-utils device-mapper-persistent-data lvm2<\/code><\/pre>\n<\/li>\n
  2. Collegare il repository\n
    $ sudo yum-config-manager --add-repo https:\/\/download.docker.com\/linux\/centos\/docker-ce.repo<\/code><\/pre>\n<\/li>\n
  3. Poi installare la community edition di docker\n
    $ sudo yum install docker-ce docker-ce-cli containerd.io<\/code><\/pre>\n<\/li>\n
  4. Aggiungere docker all'avvio automatico e avviarlo\n
    $ sudo systemctl enable docker\n$ sudo systemctl start docker<\/code><\/pre>\n<\/li>\n
  5. Aggiungere l'utente al gruppo docker per poter eseguire docker senza sudo\n
    $ usermod -aG docker user<\/code><\/pre>\n<\/li>\n<\/ol>\n
    <\/p>\n
    Il passo successivo consiste nell'installare docker-compose. L'utilit\u00e0 pu\u00f2 essere installata in diversi modi, ma io preferisco utilizzare il gestore pip e virtualenv per non appesantire il sistema con pacchetti superflui.<\/p>\n
    <\/p>\n
      \n
    1. Installa pip\n
      $ sudo yum install python-pip<\/code><\/pre>\n<\/li>\n
    2. Installa virtualenv\n
      $ pip install virtualenv<\/code><\/pre>\n<\/li>\n
    3. Successivamente, \u00e8 necessario creare una cartella per il progetto e inizializzarla. La cartella per la gestione dei pacchetti sar\u00e0 chiamata ve.\n
      $ mkdir docker\n$ cd docker\n$ virtualenv ve<\/code><\/pre>\n<\/li>\n
    4. Per utilizzare l'ambiente virtuale, \u00e8 necessario eseguire il seguente comando nella cartella del progetto.\n
      $ source ve\/bin\/activate<\/code><\/pre>\n<\/li>\n
    5. \u00c8 possibile installare docker-compose.\n
      pip install docker-compose<\/code><\/pre>\n
      <\/p>\n
      Affinch\u00e9 i contenitori possano vedere l'uno l'altro, creiamo una rete. In default viene utilizzato il driver bridge.<\/p>\n
      $ docker network create network<\/code><\/pre>\n
      <\/p>\n
      Dopo, \u00e8 necessario configurare docker-compose; il proxy si trover\u00e0 nella cartella proxy e il sito di prova nella cartella test. Per esempio, utilizzo il nome di dominio example.com.<\/p>\n
      $ mkdir proxy\n$ mkdir test\n$ touch proxy\/docker-compose.yml\n$ touch test\/docker-compose.yml<\/code><\/pre>\n
      <\/p>\n
      Contenuto proxy\/docker-compose.yml<\/strong><\/p>\n
      \n<\/p>\n
      <\/p>\n
      version: '3'\n\nnetworks:\n  default:\n    external:\n      name: network\n\nservices:\n  nginx-proxy:\n    container_name: nginx-proxy\n    image: jwilder\/nginx-proxy\n    ports:\n      - 80:80\n      - 443:443\n    volumes:\n      - certs:\/etc\/nginx\/certs\n      - vhost.d:\/etc\/nginx\/vhost.d\n      - html:\/usr\/share\/nginx\/html\n      - \/var\/run\/docker.sock:\/tmp\/docker.sock:ro\n\n  nginx-proxy-letsencrypt:\n    container_name: nginx-proxy-letsencrypt\n    image: jrcs\/letsencrypt-nginx-proxy-companion\n    volumes: \n      - certs:\/etc\/nginx\/certs\n      - vhost.d:\/etc\/nginx\/vhost.d\n      - html:\/usr\/share\/nginx\/html\n      - \/var\/run\/docker.sock:\/var\/run\/docker.sock:ro\n    environment:\n      - NGINX_PROXY_CONTAINER=nginx-proxy\n\nvolumes:\n  certs:\n  vhost.d:\n  html:<\/code><\/pre>\n
      <\/p>\n
      Variabile d'ambiente NGINX_PROXY_CONTAINER<\/strong> \u00e8 necessaria affinch\u00e9 il contenitore letsencrypt veda il contenitore proxy. Le cartelle \/etc\/nginx\/certs, \/etc\/nginx\/vhost.d e \/usr\/share\/nginx\/html devono essere condivise da entrambi i contenitori. Per il corretto funzionamento del contenitore letsencrypt, l'applicazione deve essere accessibile sulla porta 80 e sulla porta 443.<\/p>\n
      <\/p>\n
      Contenuto test\/docker-compose.yml<\/strong><\/p>\n
      <\/p>\n
      version: '3'\n\nnetworks:\n  default:\n    external:\n      name: network\n\nservices:\n\n  nginx:\n    container_name: nginx\n    image: nginx:latest\n    environment:\n      - VIRTUAL_HOST=example.com\n      - LETSENCRYPT_HOST=example.com\n      - LETSENCRYPT_EMAIL=admin@example.com<\/code><\/pre>\n
      <\/p>\n
      Qui le variabili d'ambiente sono necessarie affinch\u00e9 il proxy gestisca correttamente le richieste al server e richieda un certificato per il nome di dominio corretto.<\/p>\n
      <\/p>\n
      Rimane solo da avviare docker-compose<\/p>\n
      <\/p>\n
      $ cd proxy\n$ docker-compose up -d\n$ cd ..\/test\n$ docker-compose up -d<\/code><\/pre>\n<\/p>\n<\/li>\n<\/ol>\n
