mysql - 无法在docker容器中安装mysql-client

Question

我正在尝试运行一个入口点脚本，该脚本要等到mysql数据库准备就绪，就像这两个示例一样:example 1和example 2
并按预期失败，并显示消息“找不到mysql”，因此在Dockerfile中，我添加了以下两行:

RUN apt-get update
RUN apt-get install mysql-client

但是我收到一条消息: 软件包“mysql-client”没有安装候选者
因此，我尝试使用 default-mysql-client ，但收到另一个错误: 错误:服务'api'生成失败:命令'/ bin / sh -c apt-get install default-mysql-client'返回非零码:1
然后我尝试使用 mariadb-client ，但仍然收到相同的错误: 错误:服务'api'生成失败:命令'/ bin / sh -c apt-get install default-mysql-client'返回非零码:1
这是我的Dockerfile

FROM tomcat:10.0.0-M7-jdk11-openjdk-buster
COPY . /tmp
RUN cp /tmp/API.war /usr/local/tomcat/webapps
WORKDIR /tmp
RUN apt-get update
RUN apt-get install default-mysql-client

有人有主意吗？

Answer 1

它是固定的，当错误要求我以是或否作出响应时，我只是没有注意错误之前的日志部分，因为它只是没有时间做出响应并立即失败:

Step 5/5 : RUN apt install default-mysql-client

所以我像这样在Dockerfile中添加了“-y”: RUN apt-get install default-mysql-client -y
