How to use docker-smtp with a WordPress container? #67

Open silviubogan opened 4 years ago

silviubogan commented 4 years ago

I have this in my docker-compose.yml (replace ... with anything valid):

wordpress:
    container_name: ...wordpress_1
    depends_on:
      - db
    image: wordpress:latest
    ports:
      - "80:80"
    volumes:
      - type: bind
        source: ./html
        target: /var/www/html
        volume:
          nocopy: true
    restart: "no"
    environment:
      WORDPRESS_DB_NAME: '...'
      WORDPRESS_DB_USER: '...'
      WORDPRESS_DB_PASSWORD: '...'
      WORDPRESS_DB_HOST: db:3306
      WORDPRESS_TABLE_PREFIX: 'wp_'
      WORDPRESS_AUTH_KEY: '...'
      WORDPRESS_SECURE_AUTH_KEY: '...'
      WORDPRESS_LOGGED_IN_KEY: '...'
      WORDPRESS_NONCE_KEY: '...'
      WORDPRESS_AUTH_SALT: '...'
      WORDPRESS_SECURE_AUTH_SALT: '...'
      WORDPRESS_LOGGED_IN_SALT: '...'
      WORDPRESS_NONCE_SALT: '...'

and this:

  smtp:
    image: namshi/smtp
    container_name: ...smtp_relay_1
    restart: "no"
    ports:
      - "25:25"

It seems that the SMTP is not accessible from the Contact Form 7 WordPress plugin which I use through the REST API. How can I test the smtp container in a fast and good way or how can I change the docker-compose.yml file to make it work?

When I run $ docker-compose up I do not get errors.

The JSON object I get in the browser is this:

{into: "#", status: "mail_failed", message: "There was an error trying to send your message. Please try again later."}

The related forum question is here.

Thank you.

Hello, Try run docker-compose logs -f ...smtp_relay_1 and see what was the reason. When it is not autorized you can find in his logs.

The parameter -f is for monitoring. So:

  1. Open your SSH and run docker-compose logs -f smtp
  2. With other SSH, enter to your Wordpress installation by runing docker-compose exec wordpress bash and do a ping to your smtp service, like: ping ...smtp_relay_1
  3. If you got response, so do an submit from your Contact Form 7 WordPress plugin. And monitor your smtp window
  4. Paste here what you saw in this window and let me see if I can give you some help. @silviubogan

I tried your commands. This did not help me install the ping command, as you can see below.

$ docker-compose logs -f ...smtp_relay_1

Thank you.

It seems that you haven't updated your apt repositore. So:

apt update && apt install -y iputils-ping , and then, ping your smtp container, acording to your log, it maybe ...smtp_relay_1.

Let's see if you can succes on ping your exim server.
