基于tutum/lamp镜像搭建GoLang网络应用
2015-01-27 wcdj摘要：Docker Hub上有较多的LAMP镜像，其中tutum/lamp镜像较为出名，本文使用tutum/lamp作为基础镜像，并在其上添加go编译环境，然后创建和测试一个支持GoLang网络应用的镜像。
过程如下：
1，从Docker Hub下载tutum/lamp镜像
root@gerryyang:~# docker search -s 5 lamp
NAME DESCRIPTION STARS OFFICIAL AUTOMATED
tutum/lamp LAMP image - Apache listens in port 80, an... 47
dockerfiles/centos-lamp 8
root@gerryyang:~# docker pull tutum/lamp

2，启动tutum/lamp容器，并测试服务访问是否ok
root@gerryyang:~# docker run -d -p 40080:80 -p 43306:3306 tutum/lamp
54a001909fd1746a07876c6cba70b681b9826580ce90d7f7f5a22d22226bf6e5

3，基于镜像 tutum/lamp:latest 使用 Dockerfile 编译一个GoLang网络服务的镜像 tutum_lamp_golang_gerry:1.0
Dockerfile源码请见GitHub。
root@gerryyang:~/golang_tutum_lamp# docker images
REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE
tutum_lamp_golang_gerry 1.0 6b660dc40f2b 2 minutes ago 661.4 MB
tutum/lamp latest b84edafb1623 3 months ago 436.7 MB
带有GoLang app的镜像已经创建好了，使用debug.sh脚本进入容器确认服务是否正常，比如，启动脚本路径是否正确，二进制文件是否已经生成。
4，以后台的方式启动容器，即启动GoLang服务，并通过外网测试
docker run -d -p 9090:9090tutum_lamp_golang_gerry:1.0
root@gerryyang:~# docker ps a

通过外网测试服务是否可以访问
注意：使用Dockerfile创建镜像时，会继承父镜像的开放端口，但却不会继承启动命令，因此要再子镜像的run.sh启动脚本里指定要启动的服务，否则父镜像已有的服务无法访问。
