选择合适的数据挂载位置：一般选取容量大的硬盘块：
df -h
1、portainer容器可视化管理
容器构建命令：
$ docker search portainer
$ docker pull portainer:latest
$ docker run \
-d \
-p 9000:9000 \
--restart=always \
-v /var/run/docker.sock:/var/run/docker.sock \
-v /data/docker_data_volume_list/portainer_data:/data \
-v /data/docker_data_volume_list/portainer_web/public:/public \
--name prtainer-test \
portainer/portainer
2、MySql环境
账号密码：root/123456
容器构建命令：
$ docker search mysql
$ docker pull mysql:8.0.19
$ docker run \
-d \
-p 3306:3306 \
--restart=always \
--name mysql-test \
-v /data/docker_data_volume_list/mysql/log:/var/log/mysql \
-v /data/docker_data_volume_list/mysql/data:/var/lib/mysql \
-v /data/docker_data_volume_list/mysql/conf:/etc/mysql/conf.d \
-e MYSQL_ROOT_PASSWORD=123456 \
mysql:8.0.19
3、redis环境
密码：zlHjV0tdO5yNYMhbrCfJE1ZA6I2na
$ docker search redis
$ docker pull redis:latest
$ docker run \
-d \
--name redis-test \
-p 6379:6379 \
--restart=always \
-v /data/docker_data_volume_list/redis/conf/redis.conf:/etc/redis/redis.conf \
-v /data/docker_data_volume_list/redis/conf/data:/data \
redis \
--requirepass "zlHjV0tdO5yNYMhbrCfJE1ZA6I2naR"
4、阿里巴巴流量卫兵sentinel-dashboard
地址：http://ip:8858
sentinel/sentinel
容器构建命令：
$ docker search sentinel-dashboard
$ docker pull bladex/sentinel-dashboard
$ docker run \
-d \
-p 8858:8858 \
--name sentinel-test \

bladex/sentinel-dashboard:latest
5、Tomcat
$ docker pull tomcat:jre11-openjdk-slim-buster
$ docker run \
--rm/--restart=always \ # 二选一

-v /home/docker_volume_list/tomcat_volume/log_dir:/usr/local/tomcat/logs \
tomcat:jre11-openjdk-slim-buster
6、nacos
部署时注意版本问题，并且开放心跳监测的端口7848、8848、9848
数据库先建表:https://github.com/alibaba/nacos/blob/develop/distribution/conf/nacos-mysql.sql
$ docker search nacos/nacos-server
$ docker pull nacos/nacos-server
$ docker run \
--rm/--restart=always \
-d \
--name nacosByJHL \
# -p 7848:7848 \
# -p 8848:8848 \
# -p 9848:9848 \
--network host \
-e MODE=standalone \
-e SPRING_DATASOURCE_PLATFORM=mysql \
-e MYSQL_SERVICE_HOST=192.168.8.8 \
-e MYSQL_SERVICE_PORT=3306 \
-e MYSQL_SERVICE_DB_NAME=nacos_config \
-e MYSQL_SERVICE_USER=root \
-e MYSQL_SERVICE_PASSWORD=woaini \
nacos/nacos-server

7、apollo
docker部署文档地址
1.先起一个临时容器，将启动脚本复制出来
2.新建数据库表（docker部署文档地址中自取）
3.更改数据库连接配置
# apollo config db info
apollo_config_db_url="jdbc:mysql://192.168.8.8:3306/ApolloConfigDB?characterEncoding=utf8&serverTimezone=Asia/Shanghai"
apollo_config_db_username=root
apollo_config_db_password=woaini
# apollo portal db info
apollo_portal_db_url="jdbc:mysql://192.168.8.8:3306/ApolloPortalDB?characterEncoding=utf8&serverTimezone=Asia/Shanghai"
apollo_portal_db_username=root
apollo_portal_db_password=woaini
4.注意：一定要以主机模式启动,不然apollo自己的eureka服务协调中心无法正常协调apollo的各个服务(主要指config service、admin service、Portal service之间的协调)
$ docker pull nobodyiam/apollo-quick-start
$ docker run \
--rm/--restart=always \
--name apolloByJHL \
--network host \
-v /docker_volume/demo.sh:/apollo-quick-start/demo.sh \
nobodyiam/apollo-quick-start \
bash -c "/apollo-quick-start/demo.sh start && tail -f /dev/null"
报错：WARNING: Published ports are discarded when using host network mode
原因：
docker启动时指定--network=host或-net=host，如果还指定了-p或-P，那这个时候就会有此警告，并且通过-p或-P设置的参数将不会起到任何作用，端口号会以主机端口号为主，重复时则递增。
解决:
解决的办法就是不指定-p参数，或者使用docker的其他网络模式，例如--network=bridge，这样就可以解决问题
eureka地址：http://ip:8080
admin地址：http://ip:8090
Apollo UI 界面：http://ip:8070/
apollo/admin
8、nginx
1.找到合理的数据挂载点
查容量df -h 挂载到容量最大的目录
2.创建目录
mkdir -p /最大容量挂载点/docker_data_volume_list/nginx/conf.d
mkdir -p /最大容量挂载点/docker_data_volume_list/nginx/html/index.html
mkdir -p /最大容量挂载点/docker_data_volume_list/nginx/html/
3.挂载映射
vim /最大容量挂载点/docker_data_volume_list/nginx/conf.d/default.conf
server {
listen 80;
server_name localhost;
#charset koi8-r;
#access_log /var/log/nginx/host.access.log main;
location / {
root /usr/share/nginx/html;
index index.html index.htm;
}
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}
# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#
#location ~ \.php$ {
# proxy_pass http://127.0.0.1;
#}
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
#location ~ \.php$ {
# root html;
# fastcgi_pass 127.0.0.1:9000;
# fastcgi_index index.php;
# fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
# include fastcgi_params;
#}
# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
# deny all;
#}
}
vim /最大容量挂载点/docker_data_volume_list/nginx/nginx.conf
user nginx;
worker_processes 1;
error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;
events {

}
http {
include /etc/nginx/mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$time_local] "$request" '

'"$http_user_agent" "$http_x_forwarded_for"';
access_log /var/log/nginx/access.log main;
sendfile on;
#tcp_nopush on;

include /etc/nginx/conf.d/*.conf;
}

Thank you for using nginx.
部署脚本
$ docker search nginx
$ docker pull docker.io/nginx
$ docker run \
-d \
--name nginx-test \
--rm \
-p 9111:80 \
# 映射容器内nginx默认配置文件目录
-v /最大容量挂载点/docker_data_volume_list/nginx/conf.d:/etc/nginx/conf.d \
# 映射主配置文件
-v /最大容量挂载点/docker_data_volume_list/nginx/nginx.conf:/etc/nginx/nginx.conf \
# 映射日志文件
-v /最大容量挂载点/docker_data_volume_list/nginx/log:/var/log/nginx \
# 映射静态文件
-v /最大容量挂载点/docker_data_volume_list/nginx/html:/usr/share/nginx/html \
