docker-images - Dockerfile build install mysql的時候，彈出輸入root密碼之後，沒反應？

Question

Dockerfile build 執行指令apt-get install mysql-server的時候，彈出輸入root密碼之後，輸入秘密，回車，沒反應啊！這怎麼回事？

Dockfile:

FROM ubuntu:latest
RUN apt-get -qq update
RUN apt-get install -qqy nginx mysql-server php-mcrypt

Answer 1

mysql是不可以直接這麼安裝的。

應該參考下面mysql官方鏡像的做法：

ENV MYSQL_VERSION 8.0.0-dmr-1debian8

RUN echo "deb http://repo.mysql.com/apt/debian/ jessie mysql-${MYSQL_MAJOR}" > /etc/apt/sources.list.d/mysql.list

# the "/var/lib/mysql" stuff here is because the mysql-server postinst doesn't have an explicit way to disable the mysql_install_db codepath besides having a database already "configured" (ie, stuff in /var/lib/mysql/mysql)
# also, we set debconf keys to make APT a little quieter
RUN { \
        echo mysql-community-server mysql-community-server/data-dir select ''; \
        echo mysql-community-server mysql-community-server/root-pass password ''; \
        echo mysql-community-server mysql-community-server/re-root-pass password ''; \
        echo mysql-community-server mysql-community-server/remove-test-db select false; \
    } | debconf-set-selections \
    && apt-get update && apt-get install -y mysql-server="${MYSQL_VERSION}"
