How to accept license agreement during docker build?

Question

How to write the Dockerfile that can pass yes to prompting license agreement?

1. under Dockerfile directory, docker build -t "{user}/{tags}" . then build failed.
   

2. docker logs {container id}, show message as below:

   Preparing to unpack .../ttf-mscorefonts-installer_3.4+nmu1ubuntu2_all.deb ...
   debconf: unable to initialize frontend: Dialog
   debconf: (TERM is not set, so the dialog frontend is not usable.)
   debconf: falling back to frontend: Readline
   Configuring ttf-mscorefonts-installer
   
   TrueType core fonts for the Web EULA END-USER LICENSE AGREEMENT FOR

   Do you accept the EULA license terms? [yes/no]
   

Answer 1

For me, the ACCEPT_EULA=y before the install did the job, like

RUN apt-get update && ACCEPT_EULA=Y apt-get install PACKAGE -y
