    ## this is the all-in-one, standalone Discourse Docker container
    ## template
    ##
    ## After making changes to this file, you MUST rebuild
    ## /var/discourse/launcher rebuild app
    ##
    ## BE *VERY* CAREFUL WHEN EDITING!
    ## YAML FILES ARE SUPER SUPER SENSITIVE TO MISTAKES IN WHITESPACE OR ALIGNMENT!
    ## visit http://www.yamllint.com/ to validate this file as needed

    templates:
      - "templates/postgres.template.yml"
      - "templates/redis.template.yml"
      - "templates/web.template.yml"
      - "templates/web.ratelimited.template.yml"
    ## Uncomment these two lines if you wish to add Lets Encrypt (https)
      - "templates/web.ssl.template.yml"
      - "templates/web.letsencrypt.ssl.template.yml"

    ## which TCP/IP ports should this container expose?
    ## If you want Discourse to share a port with another webserver like Apache or nginx,
    ## see https://meta.discourse.org/t/17247 for details
    expose:
      - "80:80" # fwd host port 80 to container port 80 (http)
      - "443:443" # https

    params:
      db_default_text_search_config: "pg_catalog.english"

      ## Set db_shared_buffers to a max of 25% of the total memory.
      ## will be set automatically by bootstrap based on detected RAM, or you can override
      #db_shared_buffers: "256MB"

      ## can improve sorting performance, but adds memory usage per-connection
      #db_work_mem: "40MB"

      ## Which Git revision should this container use? (default: tests-passed)
      #version: tests-passed

    env:
      LANG: en_US.UTF-8
      # DISCOURSE_DEFAULT_LOCALE: en
      LETSENCRYPT_ACCOUNT_EMAIL: ' ********** @gmail.com'

    ## How many concurrent web requests are supported? Depends on memory and CPU cores.
      ## will be set automatically by bootstrap based on detected CPUs, or you can override
      #UNICORN_WORKERS: 3

      ## TODO: The domain name this Discourse instance will respond to
      DISCOURSE_HOSTNAME: 'speckme.nz'

      ## Uncomment if you want the container to be started with the same
      ## hostname (-h option) as specified above (default "$hostname-$config")
      #DOCKER_USE_HOSTNAME: true

      ## TODO: List of comma delimited emails that will be made admin and developer
      ## on initial signup example 'user1@example.com,user2@example.com'
      DISCOURSE_DEVELOPER_EMAILS: ' ******** @gmail.com'

      ## TODO: The SMTP mail server used to validate new accounts and send notifications
      DISCOURSE_SMTP_ADDRESS: smtp.gmail.com # required
      DISCOURSE_SMTP_PORT: 587 # (optional, default 587)
      DISCOURSE_SMTP_USER_NAME: *********** @gmail.com # required
      DISCOURSE_SMTP_PASSWORD: ********** # required, WARNING the char '#' in pw can cause problems!
      DISCOURSE_SMTP_ENABLE_START_TLS: true # (optional, default true)

      ## If you added the Lets Encrypt template, uncomment below to get a free SSL certificate
      LETSENCRYPT_ACCOUNT_EMAIL: ************ @gmail.com

      ## The CDN address for this Discourse instance (configured to pull)
      ## see https://meta.discourse.org/t/14857 for details
      #DISCOURSE_CDN_URL: //discourse-cdn.example.com

    ## The Docker container is stateless; all data is stored in /shared
    volumes:
      - volume:
          host: /var/discourse/shared/standalone
          guest: /shared
      - volume:
          host: /var/discourse/shared/standalone/log/var-log
          guest: /var/log

    ## Plugins go here
    ## see https://meta.discourse.org/t/19157 for details
    hooks:
      after_code:
        - exec:
            cd: $home/plugins
            cmd:
              - git clone https://github.com/discourse/docker_manager.git

    ## Any custom commands to run after building
    run:
      - exec: echo "Beginning of custom commands"
      ## If you want to set the 'From' email address for your first registration, uncomment and change:
      ## After getting the first signup email, re-comment the line. It only needs to run once.
      #- exec: rails r "SiteSetting.notification_email='info@unconfigured.discourse.org'"
      - exec: echo "End of custom commands"
