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 [OK]
dockerfiles/centos-lamp 8 [OK]
root@gerryyang:~# docker pull tutum/lamp

tutum/lamp           latest       b84edafb1623    3 months ago    436.7 MB

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
root@gerryyang:~# docker ps a

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 9090:9090 tutum_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。
