    [info]* Port forwarding:[/]

        Ports are forwarded to the running docker containers for webserver and database
          * {SSH_PORT} -> forwarded to Airflow ssh server -> airflow:22
          * {WEBSERVER_HOST_PORT} -> forwarded to Airflow webserver -> airflow:8080
          * {FLOWER_HOST_PORT} -> forwarded to Flower dashboard -> airflow:5555
          * {POSTGRES_HOST_PORT} -> forwarded to Postgres database -> postgres:5432
          * {MYSQL_HOST_PORT} -> forwarded to MySQL database  -> mysql:3306
          * {MSSQL_HOST_PORT} -> forwarded to MSSQL database  -> mssql:1443
          * {REDIS_HOST_PORT} -> forwarded to Redis broker -> redis:6379

        Direct links to those services that you can use from the host:

          * ssh connection for remote debugging: ssh -p {SSH_PORT} airflow@127.0.0.1 (password: airflow)
          * Webserver: http://127.0.0.1:{WEBSERVER_HOST_PORT}
          * Flower:    http://127.0.0.1:{FLOWER_HOST_PORT}
          * Postgres:  jdbc:postgresql://127.0.0.1:{POSTGRES_HOST_PORT}/airflow?user=postgres&password=airflow
          * Mysql:     jdbc:mysql://127.0.0.1:{MYSQL_HOST_PORT}/airflow?user=root
          * MSSQL:     jdbc:sqlserver://127.0.0.1:{MSSQL_HOST_PORT};databaseName=airflow;user=sa;password=
                       Airflow123
          * Redis:     redis://127.0.0.1:{REDIS_HOST_PORT}/0

    [info]* How can I add my stuff in Breeze:[/]

        * Your dags for webserver and scheduler are read from `/files/dags` directory
          which is mounted from folder in Airflow sources:
          * `{AIRFLOW_SOURCES_ROOT}/files/dags`

        * You can add `airflow-breeze-config` directory. Place it in
          `{AIRFLOW_SOURCES_ROOT}/files/airflow-breeze-config` and:
            * Add `variables.env` - to make breeze source the variables automatically for you
            * Add `.tmux.conf` - to add extra initial configuration to `tmux`
            * Add `init.sh` - this file will be sourced when you enter container, so you can add
              any custom code there.

        * You can put any other files. You can add them in
          `{AIRFLOW_SOURCES_ROOT}/files` folder
          and they will be visible in `/files/` folder inside the container

        [info]* Other options[/]

        Check out `--help` for `breeze` command. It will show you other options, such as running
        integration or starting complete Airflow using `start-airflow` command as well as ways
        of cleaning up the installation.

        Make sure to run `setup-autocomplete` to get the commands and options auto-completable
        in your shell.

        You can disable this cheatsheet by running:

            breeze setup config --no-cheatsheet
