2、创建Dockerfile

# vim Dockerfile
# docker build -t fwq-server:0.1 .
# docker run -d --restart always --name fwq-server -p 7233:7233 -p 7234:7234 -p 7235:7235 -v /home/tunnel/system:/usr/local/jar fwq-server:0.1
FROM openjdk:11.0.16-jre
ADD sources.list /etc/apt/
RUN apt-get update -y && apt-get install -y vim
RUN apt-get update -y && apt-get install -y iputils-ping
RUN apt-get update -y && apt-get install -y dnsutils
RUN apt-get update -y && apt-get install -y iproute2
MAINTAINER 295672923@qq.com
WORKDIR /usr/local/jar
VOLUME /usr/local/jar
ENV TZ Asia/Shanghai
EXPOSE 7233 7234 7235
CMD ["bash","./run.sh"]

容器内安装

1.进入docker容器

docker exec -it 容器名 /bin/bash

2.执行安装命令(apt-get 或者yum)

apt-get update && apt-get install -y vim

3.如果apt-get命令失败，则使用yum命令

4.安装一个ping命令
apt-get update && apt-get install -y iputils-ping
