三 镜像相关

1. 查看镜像

docker images
docker images –q # 查看所用镜像的id

1
2
3

2. 搜索镜像

docker search 镜像名称

1
2

3. 拉取镜像
   从Docker仓库下载镜像到本地，镜像名称格式为 名称:版本号，如果版本号不指定则是最新的版本。如果不知道镜像版本，可以去docker hub 搜索对应镜像查看

docker pull 镜像名称:版本号

1
2

4. 删除镜像

docker ps –a # 查看所有容器

1
2
3

2. 创建并启动容器

参数说明：

-i：保持容器运行。通常与 -t 同时使用。加入it这两个参数后，容器创建后自动进入容器中，退出容器后，容器自动关闭。

-t：为容器重新分配一个伪输入终端，通常与 -i 同时使用。

-d：以守护（后台）模式运行容器。创建一个容器在后台运行，需要使用docker exec 进入容器。退出后，容器不会关闭。

-it 创建的容器一般称为交互式容器，-id 创建的容器一般称为守护式容器

–name：为创建的容器命名。

–restart=always :容器自启

docker update --restart=always 容器ID/容器名称：运行的容器添加自启动

参数说明：

-p 3307:3306：将容器的 3306 端口映射到宿主机的 3307 端口。

-v $PWD/conf:/etc/mysql/conf.d：将主机当前目录下的 conf/my.cnf 挂载到容器的 /etc/mysql/my.cnf。配置目录

-v $PWD/logs:/logs：将主机当前目录下的 logs 目录挂载到容器的 /logs。日志目录

-v $PWD/data:/var/lib/mysql ：将主机当前目录下的data目录挂载到容器的 /var/lib/mysql 。数据目录

镜像制作

1. 容器转为镜像

docker commit 容器id 镜像名称:版本号                 从容器创建一个新的镜像
1

docker save -o 压缩文件名称 镜像名称:版本号           将指定镜像保存成 tar 归档文件
1

docker load –i 压缩文件名称                        导入使用docker save命令导出的镜像

2

日志查看

1、Docker logs 命令格式
docker logs 参数 容器名/容器id

参数说明：

–details 显示提供给日志的其他详细信息
–follow , -f 实时跟踪日志输出
–since 显示自某个timestamp之后的日志大于等于某个时间，或相对时间，如1h 就是1h）
–tail , -n all 从日志末尾显示的行数，默认值为all 全部
–timestamps , -t 日志每行显示日志时间戳
–until 显示自某个timestamp之前的日志小于等于某个时间，或相对时间，如30m（即30分钟）

用法示例

#通过容器名
docker logs tomcat8

#通过容器id 
docker logs fe734a934051

#通过容器id 显示时间戳
docker logs -t -n 5 fe734a934051

#查询最近1小时的日志最新10行日志
docker logs --tail=10 --since 1h tomcat8

#实时跟踪tomcat8日志每次显示最新15行日志
docker logs --follow --tail=15 tomcat8docker logs --f --tail=15 tomcat8

#查询tomcat8的日志内容包含error取最新5行，注意需要使用2>&1进行重定向
docker logs -n 5 tomcat8 2>&1 | grep 'error'

#查询tomcat8的包含错误的日志并且写入 /usr/logs_error001.txt
docker logs -t tomcat8 | grep 'error' >> /usr/logs_error001.txt

#查询指定时间范围内的tomcat8的日志文件 取最新8行
docker logs -t -n 8 --since="2022-08-02T13:23:37" --until="2022-08-02T22:23:37" tomcat8

docker 安装nginx

1.安装命令

docker run -d --name nginx-server -v /opt/nginx-server:/home/share/nginx/html:ro nginx:latest
1

2 获取安装好的nginx 访问地址
(其中的b73 是执行命令docker ps 后CONTAINER ID 下的前三个字母)

 docker inspect b73 | grep "IPAddress"
            "SecondaryIPAddresses": null,
            "IPAddress": "172.17.0.2",
                    "IPAddress": "172.17.0.2",
1
2
3
4

3 .尝试访问

//如果访问不到说明/opt/nginx-server下没有index.html
 curl http://172.17.0.2

//所以执行命令 添加一个index.html
 echo "nginx is working" > /opt/nginx-server/index.html 
 //获取docker容器的元数据
 docker inspect  26a

在docker host中暴露端口(80:80容器内部80端口映射到服务器80端口)

docker run -d -p 80:80 --name nginx-server-port -v /opt/nginx-server-port:/usr/share/nginx/html:ro nginx

echo "nginx is runing" > /opt/nginx-server-port/index.html 
//查看防火墙状态
firewall-cmd --state

安装jdk

1. 根据文章docker安装指定版本的tag镜像得到安装jdk的docker命令

docker pull primetoninc/jdk:1.8

1
2

发现docker pull镜像慢的让人着急，我们来配置下镜像加速器（阿里云的容器镜像服务地址：容器镜像服务）

尝试进入/etc/docker目录，查看文件

发现没有daemon.json文件，那么我们创建该文件

touch daemon.json
1

写入配置

sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://xxx.mirror.aliyuncs.com"]
}
EOF


1
2
3
4
5
6
7

刷新配置文件并重启docker服务

sudo systemctl daemon-reload
sudo systemctl restart docker
1
2

2.查看本地镜像

docker images

1
2

在上图中可以看到我们已经安装了jdk1.8 镜像

3.启动jdk容器（其中，–name=后的jdk1.8是为容器指定了一个别名，而最后的primetoninc/jdk:1.8那个指的是下载镜像时的名称。）该命令的意思为：使用docker镜像primetoninc/jdk:1.8以后台模式启动一个容器,并将容器命名为jdk1.8

docker run -it --name jdk1.8 -d primetoninc/jdk:1.8

1
2

4.查看docker进程是否启动成功
docker ps

4.进入jdk容器，查看是否安装正确（即查看安装之后的目录）

sudo docker exec -it jdk1.8 /bin/bash
查看jsk版本

java -version

[root@localhost ~]# docker exec -it jdk1.8 /bin/bash
[root@17169c7e0196 /]# java -version
java version "1.8.0_152"
Java(TM) SE Runtime Environment (build 1.8.0_152-b16)
Java HotSpot(TM) 64-Bit Server VM (build 25.152-b16, mixed mode)

运行tomcat应用容器（https://hub.docker.com/_/tomcat 有介绍怎么安装使用）

1. 不暴露端口运行

//首先
docker pull tomcat:9.0

docker run -d --rm tomcat:9.0

//查看ip地址尝试访问
[root@localhost docker]# docker inspect e05 | grep "IPAddress"
            "SecondaryIPAddresses": null,
            "IPAddress": "172.17.0.2",
                    "IPAddress": "172.17.0.2",
