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                   [OK]

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
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

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

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

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

9454db5b40f2        ubuntu_sshd_gcc_gerry:14.04          "/run.sh"           8 minutes ago       Up 8 minutes        0.0.0.0:10022->22/tcp                                                    admiring_hypatia     

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。
