You’re using an old version of phx_new, which is why you get the old template.

Use mix archive.install hex phx_new to upgrade to the latest version of the generator, and then try mix phx.new again, you shouldn’t get any brunch files.

Thank you for reply.
I thought I use mix archive.install hex phx_new on Docker..

• Dockerfile

FROM elixir:1.9.1

RUN curl -sL https://deb.nodesource.com/setup_10.x | bash \
  && apt-get install -y nodejs

RUN npm install npm@latest -g

RUN mix local.hex --force && \
  mix archive.install hex phx_new 1.4.9 --force && \
  mix local.rebar --force && \
  mix archive.install https://github.com/phoenixframework/archives/raw/master/phx_new.ez --force

RUN apt-get install -y inotify-tools

WORKDIR /app

• command

$ docker-compose run web mix phoenix.new APPNAME

Do not use phoenix.new its a legacy task and will eventually be removed. Please use phx.new.

I’m sorry for the mistake.
The problem was solved.
Thank you for your supports.
