我的目標(biāo)是擁有一個具有運(yùn)行MySQL服務(wù)的docker容器.所以每當(dāng)我啟動容器時,數(shù)據(jù)庫都處于初始狀態(tài)并且MySQL正在運(yùn)行.

幾乎一切都很好但是當(dāng)我啟動容器時MySQL服務(wù)沒有運(yùn)行.每次在控制臺中我都必須像這樣啟動它：service mysql start.

以下是我構(gòu)建和運(yùn)行容器的步驟：

$docker build -t executer:mysql .

這是Dockerfile的內(nèi)容：

FROM debian:wheezy

# add our user and group first to make sure their IDs get assigned consistently, regardless of whatever dependencies get added

RUN groupadd -r mysql && useradd -r -g mysql mysql

# 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)

運(yùn)行我的容器后,如何更改我的Dockerfile以運(yùn)行MySQL服務(wù)？
