I modify app.yml  
## this is the all-in-one, standalone Discourse Docker container template

```
# You may add rate limiting by uncommenting the web.ratelimited template.
# Out of the box it allows 12 reqs a second per ip, and 100 per minute per ip
# This is configurable by amending the params in this file

templates:
  - "templates/postgres.template.yml"
  - "templates/redis.template.yml"
  - "templates/web.template.yml"
  - "templates/sshd.template.yml"
  - "templates/web.ratelimited.template.yml"

## which TCP/IP ports should this container expose?
expose:
  - "80:80" # fwd host port 80 to container port 80 (http)
  - "2222:22" # fwd host port 2222 to container port 22 (ssh)

# any extra arguments for Docker?
# docker_args:

params:
  db_default_text_search_config: "pg_catalog.english"

  ## Set db_shared_buffers to a max of 25% of the total memory.
  ##
  ## On 1GB installs set to 128MB (to leave room for other processes)
  ## on a 4GB instance you may raise to 1GB
  db_shared_buffers: "128MB"
  #
  ## Set higher on large instances it defaults to 10MB, for a 3GB install 40MB is a good default
  ## this improves 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

  ## TODO: How many concurrent web requests are supported?
  ## With 2GB we recommend 3-4 workers, with 1GB only 2
  ## If you have lots of memory, use one or two workers per logical CPU core
  UNICORN_WORKERS: 2

  ## 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: 'info@example.com'

  ## TODO: The domain name this Discourse instance will respond to
  DISCOURSE_HOSTNAME: 'discourse.example.com'

  ## TODO: The mailserver this Discourse instance will use
  DISCOURSE_SMTP_ADDRESS: smtp.example.com # (mandatory)
  #DISCOURSE_SMTP_PORT: 587 # (optional)
  #DISCOURSE_SMTP_USER_NAME: user@example.com # (optional)
  #DISCOURSE_SMTP_PASSWORD: pa$$word # (optional, WARNING the char '#' in pw can cause problems!)
  #DISCOURSE_SMTP_ENABLE_START_TLS: true # (optional, default true)

  ## The CDN address for this Discourse instance (configured to pull)
  #DISCOURSE_CDN_URL: //discourse-cdn.example.com

## These containers are stateless, all data is stored in /shared
volumes:
  - volume:
      host: /home/admin/web/discourse.example.com/public_html/shared/standalone
      guest: /shared
  - volume:
      host: /home/admin/web/discourse.example.com/public_html/shared/standalone/log/var-log
      guest: /var/log

## The docker manager plugin allows you to one-click upgrade Discourse
## http://discourse.example.com/admin/docker
hooks:
  after_code:
    - exec:
        cd: $home/plugins
        cmd:
          - git clone https://github.com/discourse/docker_manager.git

## Remember, this is YAML syntax - you can only have one block with a name
run:
  - exec: echo "Beginning of custom commands"

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

  ## If you want to configure password login for root, uncomment and change:
  ## Use only one of the following lines:
  #- exec: /usr/sbin/usermod -p 'PASSWORD_HASH' root
  #- exec: /usr/sbin/usermod -p "$(mkpasswd -m sha-256 'RAW_PASSWORD')" root

  ## If you want to authorized additional users, uncomment and change:
  #- exec: ssh-import-id username
  #- exec: ssh-import-id anotherusername

  - exec: echo "End of custom commands"
  - exec: awk -F\# '{print $1;}' ~/.ssh/authorized_keys | awk 'BEGIN { print "Authorized SSH keys for this container:"; } NF>=2 {print $NF;}'

```

then run `./launcher bootstrap app` (after 8 min) in end `./launcher start app` but receive error:  
_`Error response from daemon: Cannot start container e0a9864b92d1ee65eabaa6301ee00d5248535c130c0bff585219f27f25812950: failed to create endpoint app on network bridge: Error starting userland proxy: listen tcp 0.0.0.0:80: bind: address already in use`_
