将启动脚本添加到dockerfile [英] adding startup script to dockerfile

问题描述

我已经使用openjdk构建了docker镜像.

I have built my docker image using openjdk.

# config Dockerfile
FROM openjdk:8
COPY . /usr/src/myapp
WORKDIR /usr/src/myapp

# build image
docker build -t shantanuo/dbt .

使用此命令可以正常工作...

It is working as expected using this command...

docker run -p 8081:8080  -it shantanuo/dbt

登录后，我必须运行此命令...

Once I log-in, I have to run this command...

sh bin/startup.sh

---

我的问题:是否可以将启动命令添加到dockerfile?我尝试将这一行添加到我的dockerfile中.

---

My Question: Is it possible to add the startup command to dockerfile? I tried adding this line in my dockerfile.

CMD ["sh", "bin/startup.sh"]

但是在构建映像之后，我无法使用-d参数启动容器.

But after building the image, I can not use -d parameter to start the container.

推荐答案

您可以使用 entrypoint 运行启动脚本.在入口点，您可以指定您的自定义脚本，然后运行catlina.sh.示例:

You can use the entrypoint to run the startup script. In the entrypoint you can specify yoour custom script and then run catlina.sh. Example:

ENTRYPOINT "bin/startup.sh && catalina.sh run"

这将运行您的启动脚本，然后启动您的tomcat服务器.它不会退出容器.

This will run your startup script and then start your tomcat server. It wont exit the container.
