常用docker镜像启动了解

curl -o /etc/yum.repos.d/docker.repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
yum install -y docker-ce
[root@vm1 ~]# systemctl start docker
[root@vm1 ~]# docker ps
[root@vm ~]# cat /etc/docker/daemon.json
{"registry-mirrors": ["http://hub-mirror.c.163.com","https://docker.mirrors.ustc.edu.cn","https://registry.docker-cn.com"],
"insecure-registries": ["192.168.1.11:6000"]
}
[root@vm ~]# systemctl daemon-reload
[root@vm ~]# systemctl restart docker

tomcat 使用

docker run -itd -p 8080:8080 tomcat:9.0.68-jdk8-corretto-al2
docker cp  jenkins.war b02a7623d210:/usr/local/tomcat/webapps
docker exec -it b02a7623d210  bash
ls webapps
jenkins
#访问方式1
localhost:8080/jenkins    #要加jenkins才能访问

修改访问路径

docker cp 2d300106e73d:/usr/local/tomcat/conf/server.xml .
vim  server.xml
<Host name="localhost"  appBase="webapps"unpackWARs="true" autoDeploy="true"><Context path="" docBase="/usr/local/tomcat/webapps/jenkins"/><Context>   #添加此行修改目录，结尾的<Context>，具体看报错添加

打镜像

FROM tomcat:9.0.68-jdk8-corretto-al2
ADD jenkins.war /usr/local/tomcat/webapps
ENTRYPOINT ["/usr/local/tomcat/bin/catalina.sh","run"]
docker build -t jenkins:v1 .

docker run -itd -p 8080:8080 -v /root/server.xml:/usr/local/tomcat/conf/server.xml jenkins:v1
#访问方式2   localhost:8080

nacos

docker run -d \

nginx 配置目录

docker run -p 80:80 --name nginx:1.21.4  --restart=always  -itd nginx:1.21.4
root@170bc8aa1ef9:/# ls /usr/share/nginx/html/
50x.html  index.html
root@170bc8aa1ef9:/# ls /etc/nginx/
conf.d  fastcgi_params  mime.types  modules  nginx.conf  scgi_params  uwsgi_params

redis使用

docker pull redis:6.2
[root@docker ~]# docker run -p 6379:6379 --name myredis -itd redis:6.2
4464521e304d2f81964b74b616aedd5baa2d3f91e9aa74b84a522f7ce1f91025
[root@docker ~]# docker exec -it 4464521e304d bash

bash: ps: command not found
root@4464521e304d:/data# redis-cli

PONG

redis镜像里没有找到redis的conf文件，你可以使用环境变量启动

docker run --name myredis -v /root/redis/data:/data -v
/root/redis/conf/redis.conf:/etc/redis/redis.conf -d -p 6379:6379 redis redis-server
#/data数据目录

docker run -d --name redis-node-1 --net host --privileged=true redis:6.2 --cluster-enabled yes --appendonly yes --port 6381
docker run -d --name redis-node-2 --net host --privileged=true redis:6.2 --cluster-enabled yes --appendonly yes --port 6382

zookeeper使用

docker run --name zookeeper -p 2181:2181 -p 2888:2888 -p 3888:3888 -p 8080:8080 --restart always -d zookeeper[root@docker ~]# docker run -d -e TZ="Asia/Shanghai" -p 2181:2181 -v /root/zookeeper:/data --name zookeeper --restart always zookeeper

rabbit

[root@docker ~]# docker pull rabbitmq:3.8-management
[root@docker ~]# docker run -d --hostname docker  --name rabbitmq -p 15672:15672 -p 5672:5672 rabbitmq:3.8-management

Nexus3镜像

[root@vm ~]# docker pull sonatype/nexus3
[root@vm ~]# mkdir -p mkdir docker_nexus3/nexus-data
[root@vm ~]# chown -R 200 docker_nexus3/nexus-data
[root@vm ~]# chmod 777 docker_nexus3/nexus-data/ vm ~]# docker run -d --privileged=true --name=the_nexus3 -p 6000:6000 -p 8088:8081 \

权限管理不再介绍
https://blog.csdn.net/sasafa/article/details/126222609
点击左上角repositories->create repository。选择创建docker(hosted)。

[root@vm ~]# docker login 192.168.1.11:6000
[root@vm ~]# docker tag busybox:latest 192.168.1.11:6000/busybox:v1
[root@vm ~]# docker push 192.168.1.11:6000/busybox:v1

访问http://192.168.1.11:8088/repository/localhost/看到busybox实验ok

使用docker-compose同时管理多个服务

只需要一行命令docker compose up -d，就可以启动一个包含后端项目、前端项目、数据库的完整服务。

拉取Nginx镜像部署

docker run -d -p 80:80 -v /fronted-demo2:/usr/share/nginx/html --name frontend-test nginx
docker exec -it frontend-test /bin/bash

在项目根目录下新建nginx/default.confserver {listen  80;server_name  localhost;underscores_in_headers  on;root /home/frontend;location / {try_files $uri $uri/ @router;index index.html;}location @router {rewrite ^.*$ /index.html last;}
}

编写Dockerfile文件

FROM nginxWORKDIR /home/frontendCOPY build .COPY ./nginx/default.conf /etc/nginx/conf.d/default.confEXPOSE 80

docker build -t frontend .docker imagesdocker run -d -p 80:80 --name frontend-v1 frontend

拉取并启动数据库、连接数据库

docker run -p 3306:3306 --restart=always --privileged=true --name mysql -v /Users/user/Desktop/mysql/data:/var/lib/mysql -v /Users/user/Desktop/mysql/my.cnf:/etc/mysql/my.cnf -e MYSQL_ROOT_PASSWORD="123456" -d mariadb

编写docker-compose配置文件
