摘要：Docker Hub上有較多的LAMP鏡像，其中tutum/lamp鏡像較為出名，本文使用tutum/lamp作為基礎鏡像，並在其上添加go編譯環境，然後建立和測試一個支援GoLang網路應用的鏡像。

過程如下：

1，從Docker Hub下載tutum/lamp鏡像

root@gerryyang:~# docker search -s 5 lampNAME                      DESCRIPTION                                     STARS     OFFICIAL   AUTOMATEDtutum/lamp                LAMP image - Apache listens in port 80, an...   47                   [OK]dockerfiles/centos-lamp                                                   8                    [OK]root@gerryyang:~# docker pull tutum/lampPulling repository tutum/lampb84edafb1623: 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:latestroot@gerryyang:~# docker imagesREPOSITORY                      TAG                 IMAGE ID            CREATED             VIRTUAL SIZEtutum/lamp                      latest              b84edafb1623        3 months ago        436.7 MB

2，啟動tutum/lamp容器，並測試服務訪問是否ok

root@gerryyang:~# docker run -d -p 40080:80 -p 43306:3306 tutum/lamp54a001909fd1746a07876c6cba70b681b9826580ce90d7f7f5a22d22226bf6e5root@gerryyang:~# docker ps aCONTAINER ID        IMAGE                                COMMAND             CREATED             STATUS              PORTS                                                                  NAMES54a001909fd1        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，基於鏡像 tutum/lamp:latest 使用 Dockerfile 編譯一個GoLang網路服務的鏡像 tutum_lamp_golang_gerry:1.0

Dockerfile源碼請見GitHub。

root@gerryyang:~/golang_tutum_lamp# docker imagesREPOSITORY                      TAG                 IMAGE ID            CREATED             VIRTUAL SIZEtutum_lamp_golang_gerry         1.0                 6b660dc40f2b        2 minutes ago       661.4 MBtutum/lamp                      latest              b84edafb1623        3 months ago        436.7 MB

帶有GoLang app的鏡像已經建立好了，使用debug.sh指令碼進入容器確認服務是否正常，比如，啟動指令碼路徑是否正確，二進位檔案是否已經產生。

4，以背景方式啟動容器，即啟動GoLang服務，並通過外網測試

docker run -d -p 9090:9090  tutum_lamp_golang_gerry:1.0

通過外網測試服務是否可以訪問

注意：使用Dockerfile建立鏡像時，會繼承父鏡像的開放連接埠，但卻不會繼承啟動命令，因此要再子鏡像的run.sh啟動指令碼裡指定要啟動的服務，否則父鏡像已有的服務無法訪問。
