Dockerfile创建CentOS7.8.2003基础镜像下nginx-rtmp-ffmpeg流服务镜像
创建镜像
为了方便镜像的创建，比如缩小镜像体积、更改配置等，现在使用Dockerfile文件创建镜像。
编写Dockerfile文件
针对基于CentOS7.8.2003基础镜像下创建nginx-rtmp-ffmpeg流服务镜像我的Dockerfile文件如下：
FROM centos:7.8.2003
LABEL author xnz <xnzsir@gmail.com>
ENV NGINX_VERSION 1.18.0
ENV NGINX_RTMP_VERSION 1.2.1
ENV FFMPEG_VERSION 2.8.15
# Mapping Port
EXPOSE 1935
EXPOSE 80
EXPOSE 443
# FFmpeg.
# Install EPEL Release because the installation needs to use another REPO source
# Install Nux-Dextop source
# Install FFmpeg
RUN yum install -y epel-release --nogpgcheck \
&& rpm --import http://li.nux.ro/download/nux/RPM-GPG-KEY-nux.ro \
&& rpm -Uvh http://li.nux.ro/download/nux/dextop/el7/x86_64/nux-dextop-release-0-5.el7.nux.noarch.rpm \
&& yum install ffmpeg ffmpeg-devel -y
# Nginx And Nginx-rtmp-module.
# Build dependencies

# Download nginx and nginx-rtmp-module
# Install nginx and nginx-rtmp-module
# Cleanup.
RUN yum -y install gcc gcc-c++ make zlib zlib-devel openssl openssl-devel pcre pcre-devel pkgconf pkgconfig \
&& cd /tmp \
&& mkdir -p ./data/nginx-rtmp-ffmpeg \
&& cd ./data/nginx-rtmp-ffmpeg/ \
&& yum -y install wget \
&& wget http://nginx.org/download/nginx-${NGINX_VERSION}.tar.gz \
&& wget https://github.com/arut/nginx-rtmp-module/archive/v${NGINX_RTMP_VERSION}.tar.gz \
&& tar -zxf nginx-${NGINX_VERSION}.tar.gz \

&& cd nginx-${NGINX_VERSION}/ \
&& ./configure --prefix=/usr/local/src/nginx --add-module=../nginx-rtmp-module-${NGINX_RTMP_VERSION} --with-debug --with-http_ssl_module \
&& make && make install \
&& cd /usr/local/src/nginx \
&& mkdir -p ./data/hls \
&& mkdir certs \
&& rm -rf /var/cache/* /tmp/* \
&& yum -y remove gcc*
# COPY NGINX config and static files.

# Start Nginx.
ENTRYPOINT ["/usr/local/src/nginx/sbin/nginx","-g","daemon off"]
CMD ["-c","/usr/local/src/nginx/conf/nginx.conf"]Dockerfile语法可参考Docker官网： Dockerfile reference
创建Dockerfile执行目录及相关文件
- 首先在服务器宿主机创建空目录
nginx-rtmp-ffmpeg-centos7.8.2003 - 将Dockerfile文件，以及涉及到的其他文件，如：nginx.conf、SSL证书（server.crt、server.key）等文件，上传至该目录下：
- nginx.conf 配置如下：
worker_processes 1;
error_log logs/error.log debug;
events {
worker_connections 1024;
}
rtmp {
server {
listen 1935;
chunk_size 4096;
application stream {
live on;
exec ffmpeg -i rtmp://localhost:1935/stream/$name

}执行命令docker build，运行Dockerfile
参考Docker官网语法： docker build🔗
[root@VM-0-8-centos /]# docker build -t dancefingers/nginx-rtmp-ffmpeg-centos7.8.2003:1.0.0 .在执行文件过程中出现错误：
解决方式：
[root@VM-0-8-centos ~]# vim /etc/sysctl.conf [root@VM-0-8-centos ~]# net.ipv4.ip_forward=1 ##添加路由转发 或者: [root@VM-0-8-centos ~]# vim /usr/lib/sysctl.d/00-system.conf [root@VM-0-8-centos ~]# net.ipv4.ip_forward=1
重启网卡:
[root@VM-0-8-centos ~]# service network restart 或者: [root@VM-0-8-centos ~]# systemctl restart network
如果你不是上面我那样的配置，在执行
docker build，可能会出现警告：
解决方式就是yum安装epel-release时，加一个参数
--nogpgcheck：yum install -y epel-release --nogpgcheck
另外，由于我最开始使用
yum -y install gcc*安装了gcc所有依赖包，安装时会有下面警告，并且安装等待时间有点长，不过没什么使用影响，但是可以避免，使用yum -y install gcc gcc-c++安装nginx编译需要的gcc，这样安装时间缩短并且没有警告。
再次执行
docker build:
镜像创建成功
由于使用Dockerfile创建镜像时，使用命令
&& rm -rf /var/cache/* /tmp/* && yum -y remove gcc*删除并卸载了不必要得依赖和零时文件，所以生成得镜像相对于使用docker commit生成得镜像要小很多。
验证镜像
启动镜像创建容器
[root@VM-0-8-centos nginx-rtmp-ffmpeg-centos7.8.2003]# docker run -it -d -p 11935:1935 -p 1443:443 -p 180:80 dancefingers/nginx-rtmp-ffmpeg-centos7.8.2003:1.0.0
