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 Pulling repository tutum/lamp b84edafb1623: Download complete 511136ea3c5a: Download complete d497ad3926c8: Download complete ccb62158e970: Download complete e791be0477f2: Download complete 3680052c0f5c: Download complete 22093c35d77b: Download complete 5506de2b643b: Download complete 47736d0699b6: Download complete 59fd8a267ae4: Download complete 841e457fbafa: Download complete a4764b4cd917: Download complete 0541e94da879: Download complete 4a3d27d06fa4: Download complete 7a8e713e5398: Download complete 723faab6a94a: Download complete b951305b9a69: Download complete 09d2bbb9c055: Download complete ccef939b216c: Download complete 4458c9f101a6: Download complete 889d08af8392: Download complete df75de2ea944: Download complete ccb86d616ddf: Download complete cb81542002b8: Download complete 36ca8ec2e1b6: Download complete 4534351c7b4a: Download complete 05bcfc7588b0: Download complete 14e5b41d2a83: Download complete 41d45c51a5df: Download complete Status: Downloaded newer image for tutum/lamp:latest root@gerryyang:~# docker images REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE 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 CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 54a001909fd1 tutum/lamp:latest "/run.sh" 5 seconds ago Up 4 seconds 0.0.0.0:40080->80/tcp, 0.0.0.0:43306->3306/tcp romantic_yonath 3fa70f39af75 ubuntu_sshd_gcc_nginx_gerry:14.04 "/run.sh" About an hour ago Up About an hour 0.0.0.0:30022->22/tcp, 0.0.0.0:30080->80/tcp, 0.0.0.0:30443->443/tcp distracted_wilson 101bc295b601 ubuntu_sshd_gcc_apache_gerry:14.04 "/run.sh" 2 hours ago Up 2 hours 0.0.0.0:20022->22/tcp, 0.0.0.0:20080->80/tcp suspicious_sinoussi cec21c3c0a1f registry:latest "docker-registry" 2 hours ago Up 2 hours 0.0.0.0:5000->5000/tcp boring_torvalds 6906a758711c ubuntu_sshd_gcc_gerry:14.04 "/run.sh" 2 hours ago Up 2 hours 0.0.0.0:10022->22/tcp determined_kirch
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
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 CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 49ce9a13a90a ubuntu_sshd_gcc_golang_gerry:14.04 "/run.sh" 8 minutes ago Up 8 minutes 0.0.0.0:9001->9001/tcp, 0.0.0.0:50022->22/tcp dreamy_bohr dd74c290bfb2 tutum_lamp_golang_gerry:1.0 "/run.sh" 8 minutes ago Up 8 minutes 0.0.0.0:9090->9090/tcp, 0.0.0.0:50080->80/tcp, 0.0.0.0:53306->3306/tcp gloomy_galileo f24cdc4601f0 tutum/lamp:latest "/run.sh" 8 minutes ago Up 8 minutes 0.0.0.0:40080->80/tcp, 0.0.0.0:43306->3306/tcp berserk_nobel 0558ae51d1bb ubuntu_sshd_gcc_nginx_gerry:14.04 "/run.sh" 8 minutes ago Up 8 minutes 0.0.0.0:30022->22/tcp, 0.0.0.0:30080->80/tcp, 0.0.0.0:30443->443/tcp high_wozniak 22181d74ab6d ubuntu_sshd_gcc_apache_gerry:14.04 "/run.sh" 8 minutes ago Up 8 minutes 0.0.0.0:20022->22/tcp, 0.0.0.0:20080->80/tcp backstabbing_bell1 1bcd2f542592 registry:latest "docker-registry" 8 minutes ago Up 8 minutes 0.0.0.0:5000->5000/tcp desperate_sammet 9454db5b40f2 ubuntu_sshd_gcc_gerry:14.04 "/run.sh" 8 minutes ago Up 8 minutes 0.0.0.0:10022->22/tcp admiring_hypatia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。
