k8s部署mongodb副本集将keyfile放到镜像中

 

1.生成keyfile文件

cd /root/my_yaml/mongo_cluster/test1/dockerfile
openssl rand -base64 741 > mongodb-keyfile

 

2.把keyfile放入到镜像中

cd /root/my_yaml/mongo_cluster/test1/dockerfile
vi Dockerfile

FROM registry.cn-shenzhen.aliyuncs.com/hxlk8s/mongo:4.0.28
ADD mongodb-keyfile /data/config/mongodb-keyfile
RUN chown mongodb:mongodb /data/config/mongodb-keyfile && chmod 400 /data/config/mongodb-keyfile

 

3.打镜像

docker build .
[root@master dockerfile]# docker build .
