docker学习三 实例部署
1、nginx的docker部署
1.1、下载nginx镜像
docker pull nginx 1.2、运行nginx镜像
[root@iZbp10j4antmyah3ya8nioZ ~]# docker run -d -p 80:80 --name mynginx01 nginx
1c48fb6b753f73e59740c4dbd86006e68f09d8c83ba2fe8c666cb3422ec56af7
[root@iZbp10j4antmyah3ya8nioZ ~]# docker ps
#运行后的结果如下
CONTAINER ID 1c48fb6b753f
IMAGE nginx
COMMAND "/docker-entrypoint.…"
CREATED 4 seconds ago
STATUS Up 3 seconds
PORTS 0.0.0.0:80->80/tcp
NAMES mynginx01
-p 80:80 代表端口映射 宿主机的80端口映射到容器的80端口
1.3、访问nginx
在本地宿主机上访问刚才运行的nginx实例
[root@iZbp10j4antmyah3ya8nioZ ~]# curl http://localhost:80
<!DOCTYPE html>

通过外网访问
2、部署tomcat
2.1、下载tomcat镜像
docker pull tomcat:9.02.2、运行tomcat镜像
[root@iZbp10j4antmyah3ya8nioZ ~]# docker run -d -p 8080:8080 --name mytomcat01 tomcat:9.0
b9c5a058c3dfe6d8f92d1add38327338edb7971551145f2f1d964a75ee134ec0
[root@iZbp10j4antmyah3ya8nioZ ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
b9c5a058c3df tomcat:9.0 "catalina.sh run" 13 seconds ago Up 11 seconds 0.0.0.0:8080->8080/tcp mytomcat012.3、访问tomcat
可以看到tomcat已经起来了，但是要访问的资源不存在，需要把资源拷贝到相关的目录
docker exec -it 容器id /bin/bash
然后进入webapps，发现webapps下面没有任何资源，在webapps.dist目录下有资源。
把webapps.dist目录下的资源拷贝到webapps下面
root@b9c5a058c3df:/usr/local/tomcat# cp -r webapps.dist/* webapps 此时再次访问
