使用 Docker 部署 Nacos 并配置 MySQL 数据源

docker pull nacos/nacos-server:v2.2.0

rm -rf /mydata/nacos/conf
rm -rf /mydata/nacos/logs
rm -rf /mydata/nacos/data

mkdir -p /mydata/nacos/conf
mkdir -p /mydata/nacos/logs
mkdir -p /mydata/nacos/data

docker run --name nacos -d -p 8848:8848 -e MODE=standalone nacos/nacos-server

docker cp nacos:/home/nacos/logs/ /mydata/nacos
docker cp nacos:/home/nacos/conf/ /mydata/nacos
docker cp nacos:/home/nacos/data/ /mydata/nacos
#意思是吧nacos容器中的log conf data的数据复制到本机的/mydata/nacos中
④删除临时容器

docker rm -f nacos

vi /mydata/nacos/conf/application.properties

 

通过以下脚本，创建容器：
其中，关键一句：--add-host=host.docker.internal:host-gateway \
使得，在application.properties中通过：db.url.0=jdbc:mysql://host.docker.internal:3306/nacos_config?xxx，可以访问到本机的mysql数据库

docker run --name nacos-server \
-p 9007:8848 \
-p 7848:7848 \
-p 9848:9848 \
-p 9849:9849 \
--privileged=true \
--restart=always \
--add-host=host.docker.internal:host-gateway \
-e JVM_XMS=256m \
-e JVM_XMX=256m \
-e MODE=standalone \
-e PREFER_HOST_MODE=hostname \
-v /mydata/nacos/logs:/home/nacos/logs \
-v /mydata/nacos/conf/application.properties:/home/nacos/conf/application.properties \
-d nacos/nacos-server:v2.2.0
