使用Dockerfile创建镜像(ssh、systemctl、nginx、tomcat、mysql5.6、5.7)

1.ssh镜像

mkdir sshd
cd sshd

vim Dockerfile
FROM centos:7
MAINTAINER The Centos sshd
RUN yum -y update
RUN yum -y install openssh* net-tools lsof telnet passwd
RUN echo "123456" | passwd --stdin root
RUN sed -i 's/UsePAM yes/UsePAM no/g' /etc/ssh/sshd_config
RUN ssh-keygen -t rsa -f /etc/ssh/ssh_host_rsa_key
RUN sed -i '/^session\s\+required\s\+pam_loginuid.so/s/^/#/' /etc/pam.d/sshd
RUN mkdir -p /root/.ssh && chown root.root /root && chmod 700 /root/.ssh
EXPOSE 22
CMD ["/usr/sbin/sshd","-D"]

//生成镜像
docker build -t sshd:new .
//启动容器
docker run -d -P sshd:new
ssh localhost -p 32768

2.systemctl镜像

mkdir systemctl
cd systemctl

vim Dockerfile
FROM sshd:new
ENV container docker
RUN (cd /lib/systemd/system/sysinit.target.wants/; for i in *; do [ $i == \
systemd-tmpfiles-setup.service ] || rm -f $i; done); \
rm -f /lib/systemd/system/multi-user.target.wants/*; \
rm -f /etc/systemd/system/*.wants/*; \
rm -f /lib/systemd/system/local-fs.target.wants/*; \
rm -f /lib/systemd/system/sockets.target.wants/*udev; \
rm -f /lib/systemd/system/sockets.target.wants/*initctl*; \
rm -f /lib/systemd/system/basic.target.wants/*; \
rm -f /lib/systemd/system/anaconda.target.wants/*;
VOLUME [ "/sys/fs/cgroup" ]
CMD [ "/usr/sbin/init" ]

docker build -t systemd:new .

//privateged container内的root拥有真正的root权限。否则，container内的root只是一个外部的一个普通用户权限
docker run --privileged -it -v /sys/fs/cgroup:/sys/fscgroup:ro systemd:new /sbin/init &

docker exec -it 容器ID bash
systemctl status sshd
就可以使用systemctl命令了

3.nginx镜像

mkdir nginx
cd nginx
//复制nginx-1.12.2源代码包到nginx中

vi Dockerfile
FROM centos:7
MAINTAINER nginx
RUN yum -y update
RUN yum -y install pcre-devel zlib-devel gcc gcc-c++ make
RUN useradd -M -s /sbin/nologin nginx
ADD nginx-1.12.2.tar.gz /usr/local/src
WORKDIR /usr/local/src
WORKDIR nginx-1.12.2
RUN ./configure \
--prefix=/usr/local/nginx \
--user=nginx \
--group=nginx \
--with-http_stub_status_module 
RUN make && make install
ENV PATH /usr/local/nginx/sbin:$PATH
EXPOSE 80
EXPOSE 443
RUN echo "daemon off;" >> /usr/local/nginx/conf/nginx.conf
ADD run.sh /run.sh
RUN chmod 755 /run.sh
CMD ["/run.sh"]

vim run.sh
/usr/local/nginx/sbin/nginx

//创建新镜像
docker build -t nginx:new .
docker run -d -P nginx:new
docker ps -a 
http://192.168.100.129:32769/

4.tomcat镜像

mkdir tomcat
cd tomcat

vi Dockerfile
FROM centos:7
MAINTAINER tomcat
ADD jdk-8u91-linux-x64.tar.gz /usr/local
WORKDIR /usr/local/
RUN mv jdk1.8.0_91 /usr/local/java
RUN export JAVA_HOME=/usr/local/java
ENV JAVA_HOME /usr/local/java
ENV JAVA_BIN /usr/local/java/bin
ENV JRE_HOME /usr/local/java/jre
ENV PATH $PATH:/usr/local/java/bin:/usr/local/java/jre/bin
ENV CLASSPATH /usr/local/java/jre/bin:/usr/local/java/jre/lib/charsets.jar
ADD apache-tomcat-8.5.16.tar.gz /usr/local
WORKDIR /usr/local/
RUN mv apache-tomcat-8.5.16 /usr/local/tomcat8
EXPOSE 8080
ENTRYPOINT ["/usr/local/tomcat8/bin/catalina.sh","run"]

docker build -t tomcat:test
docker run -d --name tomcat01 -p 1215:8080 tomcat:test
http://192.168.100.129:1215/
