Nacos镜像制作

编写Dockerfile文件

FROM java:8 
RUN rm -f /etc/localtime \
&& ln -sv /usr/share/zoneinfo/Asia/Shanghai /etc/localtime \
&& echo "Asia/Shanghai" > /etc/timezone
 
ENV LANG en_US.UTF-8

RUN chmod 755 bin/docker-startup.sh
 
EXPOSE 8848
ENTRYPOINT ["bin/docker-startup.sh"]

制作镜像

docker build -t nacos:v2.0.3 .

1、部署mysql实例

apiVersion: v1
kind: ReplicationController
metadata:
  name: mysql
  labels:
    name: mysql
spec:
  replicas: 1
  selector:
    name: mysql
  template:

  selector:
    matchLabels:
      app: nacos-cluster

3、kubectl部署k8s

kubectl create mysql.yaml
kubectl create nacos-cluster.yaml

4、导入mysql数据，数据库文件路径conf目录下

root@nacos-cluster-2:/home/nacos/conf# cat nacos-mysql.sql
