镜像命令
查看镜像信息
查看当前本地仓库中存在哪些镜像.
docker images -q | 镜像名
// -q 和 镜像名 是可选参数a）docker images 就是 docker image ls 的缩写，用来镜像以及信息
[root@VM-8-17-centos ~]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
redis 5 c5da061a611a 2 years ago 110MB
mysql 5.7 c20987f18b13 2 years ago 448MB
rabbitmq 3.8-management 699038cb2b96 2 years ago 250MB
nacos/nacos-server 1.4.2 938169b118c7 2 years ago 956MB
redis 5.0.9 987b553c835f 3 years ago 98.3MB
bladex/sentinel-dashboard 1.8.0 61c10eaefbcf 3 years ago 147MB
nacos/nacos-server 1.2.0 763941e566bb 3 years ago 732MB
bladex/sentinel-dashboard 1.7.1 d12e18546bfd 3 years ago 148MB
- REPOSITORY：镜像名称
- TAG：版本
- IMAGE ID：镜像 id
- CREATED：镜像创建的时间（官方创建此镜像的时间）
- SIZE：镜像大小
b）docker images -q 是用来查看所有镜像 id 的
[root@VM-8-17-centos ~]# docker images -q
c5da061a611a
c20987f18b13
699038cb2b96
938169b118c7
987b553c835f
61c10eaefbcf
763941e566bb
d12e18546bfd
Ps：一个镜像的 id 是很长的，这里只会展示一个部分
c）docker images 镜像名 用来查看指定镜像信息（镜像名相同，版本不同）
[root@VM-8-17-centos ~]# docker images redis
REPOSITORY TAG IMAGE ID CREATED SIZE
redis 5 c5da061a611a 2 years ago 110MB
redis 5.0.9 987b553c835f 3 years ago 98.3MB
同理，docker images -q 镜像名 就是展示指定镜像名的镜像id.
[root@VM-8-17-centos ~]# docker images -q redis
c5da061a611a
987b553c835f下载镜像
用来下载一个镜像
docker pull 镜像名:版本号a）例如下载最新版本 redis：docker pull redis 等同于 docker pull redis:latest
b）例如下载指定版本 redis：docker pull redis:5.0.9
搜索镜像
搜索镜像，只能查看远端仓库是否存在该镜像，不能列出版本.
docker search 镜像名a）例如查看 tomcat 镜像是否存在
[root@VM-8-17-centos ~]# docker search tomcat

删除镜像
删除指定镜像
docker image rm 镜像名(name:tag) | 镜像ida）正常删除（要求：必须是没有正在运行的镜像），例如删除 tomcat:8.0 镜像
[root@VM-8-17-centos ~]# docker image rm tomcat:8.0

b）运行 tomcat 容器，设置容器与宿主机端口映射关系
docker run -p 8081:8080 tomcat:8.0Ps：-p 8081(宿主机):8080(容器)
c）运行 tomcat 容器，设置设置容器与宿主机端口映射关系，后台启动服务
docker run -p 8081:8080 -d tomcat:8.0d）运行 tomcat 容器，设置设置容器与宿主机端口映射关系，后台启动服务，自定义容器名称
docker run -p 8081:8080 -d --name tomcat_1 tomcat:8.0停止、启动、重启、暂停、恢复容器
停止容器：docker stop 容器id | name（这里的 name 是启动时自定义的）
启动容器：docker start 容器 id | name
重启容器：docker restart 容器 id | name
暂停容器：docker pause?容器 id | name
恢复容器（从暂停恢复到启动）：docker unpause?容器 id | name
杀死容器
docker kill id | name例如删除名称为 tomcat_1 的容器?
[root@VM-8-17-centos ~]# docker kill tomcat_1
tomcat_1
删除容器
a）正常删除容器（只能删除已经停止的容器）：docker rm id | name
b）强制删除容器（可以删除运行中的容器）：docker rm -f id | name
c）批量删除容器：docker rm -f $(docker ps -qa)
查看容器日志
docker logs -f id | namea）查看当前容器的日志信息，例如查看 tomcat_1 容器的日志
[root@VM-8-17-centos ~]# docker logs tomcat_1

b）通过 -f 实时监控容器内服务的日志：docker logs -f id | name
进入容器内部
docker exec -it(交互模式) id | name basha）例如进入 tomcat_1 容器内部，然后查看容器内部的文件
[root@VM-8-17-centos ~]# docker exec -it tomcat_1 bash
root@e823da882acc:/usr/local/tomcat# ls
LICENSE NOTICE RELEASE-NOTES RUNNING.txt bin conf include lib logs native-jni-lib temp webapps work
b）退出容器：exit
root@e823da882acc:/usr/local/tomcat# exit
exit
[root@VM-8-17-centos ~]# 容器与宿主机之间的文件拷贝
a）将容器中指定文件拷贝到宿主机：docker cp 容器id:容器中文件或目录 宿主机目录
例如将 tomcat 容器中的 /usr/local/tomcat/RUNNING.txt 文件拷贝到宿主机的?/root/cyk/?目录下
[root@VM-8-17-centos cyk]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
e823da882acc tomcat:8.0 "catalina.sh run" 11 minutes ago Up 11 minutes 0.0.0.0:8082->8080/tcp, :::8082->8080/tcp tomcat_1

[root@VM-8-17-centos cyk]#
[root@VM-8-17-centos cyk]# docker cp e8:/usr/local/tomcat/RUNNING.txt /root/cyk/
Successfully copied 17.9kB to /root/cyk/
[root@VM-8-17-centos cyk]# ls
RUNNING.txt
Ps：这里的 e8 是 tomcat_1?容器 id 的简写，只要能区分开，怎么简写都可以
b）将宿主机中指定文件拷贝到容器内：docker cp 宿主机目录?容器id:容器中文件或目录
如何部署一个 web 项目（war 包项目）
a）将 xxx.war 上传到 linux 服务器
b）通过 docker cp 命令将 xxx.war 赋值到 tomcat 的 webapp 目录中即可.
c）使用 ip 端口进行测试访问即可.
查看容器内运行的进程信息
docker top 容器id | namea）查看 tomcat_1 容器内运行的进程信息
[root@VM-8-17-centos cyk]# docker top tomcat_1
UID PID PPID C STIME TTY TIME CMD
root 32112 32092 0 20:49 ? 00:00:05 /docker-java-home/jre/bin/java -Djava.util.logging.config.file=/usr/local/tomcat/conf/logging.properties -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djdk.tls.ephemeralDHKeySize=2048 -Djava.protocol.handler.pkgs=org.apache.catalina.webresources -Dignore.endorsed.dirs= -classpath /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar -Dcatalina.base=/usr/local/tomcat -Dcatalina.home=/usr/local/tomcat -Djava.io.tmpdir=/usr/local/tomcat/temp org.apache.catalina.startup.Bootstrap start
查看容器内部细节
docker inspect 容器id | namea）例如查看 tomcat_1 容器内部细节?
[root@VM-8-17-centos cyk]# docker inspect tomcat_1

容器数据卷机制
作用
a）主要作用：
用来实现容器中数据和宿主机中数据进行映射的（这里可以类比 Vue 中的双向绑定，修改任意一方，另一方都会跟着修改）
b）使用场景：
- 易修改：即使我们不进入容器的内部，也可以通过修改宿主机文件系统的 conf 文件，来修改容器中的 conf 文件；
- 数据可复用：当创建了新的容器并且需要复用之前的 conf 文件时，可以直接再创建一个数据卷或者修改之前数据卷对容器目录的指向即可，来进行关联，这样就可以将之前的配置映射到新容器的配置中；
- 升级维护简单：如果来了新的容器，需要删除旧容器，也不用担心数据会被删除掉，因为数据在宿主机上还保存了一份。
?
注意
数据卷只能在容器首次启动时设置.
使用
容器首次启动时指定 -v 参数
a）使用绝对路径设置数据卷
docker run -v 宿主机绝对路径:容器内绝对路径:ro .....(其他设置)ro：表示 ready only，也就是只读的意思，如果在设置数据卷时指定 ro，代表日后从容器内访问该路径时是只读的.
Ps：这种方式会将容器该路径下的原始内容全部清空，始终以宿主机路径为主.
b）使用别名方式设置数据卷
docker run -v aa:/usr/local/tomcat/webapps ......(其他配置)aa：
- aa 代表 docker 数据卷中别名. （如果存在就直接使用，不存在就创建）
- 使用别名方式保留容器路径原始内容，前提是别名对应路径不能存在内容.
Ps：docker 根据别名创建目录默认在 /var/lib/docker/volumes/ 中.
通过 find 命令也可以查找到该路径
?
容器打包镜像
背景
a）回顾三个核心概念
仓库 repository：docker 官方维护的一个仓库，用来集中存储镜像.
镜像 image：一个镜像代表一个软件服务，特点就是 "只读".
容器 container：镜像每运行一次形成一个容器，运行的容器代表一个正在运行的软件服务.
b）为什么要将容器打包成一个新的镜像？
容器可读可写，那么基于这个特性就可以对容器进行自己的深度定制.
将容器打包成一个新的镜像，日后运行的这个容器就存在原始定制的特性.
c）原理图
将容器打包成一个新的镜像
docker commit -m "对镜像的描述" -a "作者名称" 容器id | name 镜像名:版本如下案例
[root@VM-8-17-centos cyk]# docker ps -a

镜像的备份和恢复
a）备份镜像： docker save 镜像名:tag -o （镜像名-tag）.tar
b）恢复镜像：docker load -i xxx.tar
例如 docker load -i tomcat-8.0.tar?
