docker单点启动nacos持久化密码

# docker单点启动nacos持久化密码

构建nacos-docker镜像

我这里有点小改动，里面有个sed，修改了启动脚本，官方的镜像会依赖mysql服务

vi Dcokerfile

FROM openjdk:8u252-jdk

MAINTAINER "yangfk"
LABEL version="jdk-8u252",nacos="2.0.2"
RUN test -d /home || mkdir /home

#docker镜像nacos/nacos-server:v2.1.0-slim 拷贝/home/nacos目录制作nacos.tar包
#ADD ./nacos-server-2.0.2.tar.gz /home/
ADD https://github.com/alibaba/nacos/releases/download/2.0.2/nacos-server-2.0.2.tar.gz /home

WORKDIR /home/nacos

#输出信息软链接
RUN mkdir logs && touch logs/start.out && ln -sf /dev/stdout logs/start.out && ln -sf /dev/stderr logs/start.out \

    && rm -rf /var/lib/apt/lists/* \

构建镜像，启动

docker build . -t harbor.yfklife.cn/public/nacos:2.0.2
docker run -it --restart=always -p 8848:8848 --name nacos harbor.yfklife.cn/public/nacos:2.0.2

# 单机运行持久化密码

登录界面修改nacos密码，默认账号密码：nacos/nacos

test -d /data && cd /data || mkdir /data && cd /data
test -d /data/nacos-data || mkdir /data/nacos-data
docker stop nacos
docker cp nacos:/home/nacos/data/derby-data /data/nacos-data/derby-data
docker rm -f nacos
docker run -it --restart=always -p 8848:8848 --name nacos -v /data/nacos-data/derby-data:/home/nacos/data/derby-data harbor.yfklife.cn/public/nacos:2.0.2
