KubeSphere部署项目

应用部署需要关注的信息【应用部署三要素】
1、应用的部署方式
2、应用的数据挂载（数据，配置文件）
3、应用的可访问性

1、mysql容器启动

docker run -p 3306:3306 --name mysql-01 
-v /mydata/mysql/log:/var/log/mysql 
-v /mydata/mysql/data:/var/lib/mysql 
-v /mydata/mysql/conf:/etc/mysql/conf.d 
-e MYSQL_ROOT_PASSWORD=root 
--restart=always 
-d mysql:5.7 

2、mysql配置示例

[client]
default-character-set=utf8mb4
 
[mysql]
default-character-set=utf8mb4
 
[mysqld]
init_connect='SET collation_connection = utf8mb4_unicode_ci'
init_connect='SET NAMES utf8mb4'
character-set-server=utf8mb4
collation-server=utf8mb4_unicode_ci
skip-character-set-client-handshake
skip-name-resolve

数据挂载


创建

1、集群内部，直接通过应用的 【服务名.项目名】 直接访问
mysql -uroot -hhis-mysql-glgf.his -p
2、集群外部，

1、redis容器启动

#创建配置文件

mkdir -p /mydata/redis/conf && vim /mydata/redis/conf/redis.conf

redis.conf

##配置示例
appendonly yes
port 6379
bind 0.0.0.0

#docker启动redis
docker run -d -p 6379:6379 --restart=always 
-v /mydata/redis/conf/redis.conf:/etc/redis/redis.conf 
-v  /mydata/redis-01/data:/data 
 --name redis-01 redis:6.2.5 
 redis-server /etc/redis/redis.conf

2、redis部署分析

1、es容器启动

# 创建数据目录
mkdir -p /mydata/es-01 && chmod 777 -R /mydata/es-01

# 容器启动
docker run --restart=always -d -p 9200:9200 -p 9300:9300 
-e "discovery.type=single-node" 
-e ES_JAVA_OPTS="-Xms512m -Xmx512m" 
-v es-config:/usr/share/elasticsearch/config 
-v /mydata/es-01/data:/usr/share/elasticsearch/data 
--name es-01 
elasticsearch:7.13.4

elasticsearch.yml

cluster.name: "docker-cluster"
network.host: 0.0.0.0

## WARNING: DO NOT EDIT THIS FILE. If you want to override the

## importANT: JVM heap size
################################################################
##
## The heap size is automatically configured by Elasticsearch
## based on the available memory in your system and the roles
## each node is configured to fulfill. If specifying heap is
## required, it should be done through a file in jvm.options.d,
## and the min and max should be set to the same value. For
## example, to set the heap to 4 GB, create a new file in the
## jvm.options.d directory containing these lines:
##
## -Xms4g
## -Xmx4g
##
## See https://www.elastic.co/guide/en/elasticsearch/reference/current/heap-size.html

配置

挂载配置文件
单独挂载子路径

可以使用 dev-zhao 登录，从应用商店部署

https://artifacthub.io/
使用企业空间管理员（wuhan-boss）登录，设置应用仓库
学习Helm即可，去helm的应用市场添加一个仓库地址，比如：bitnami
