For detail info, please refer to following Akshat’s article, for my article only simply summary step to build openr on ncs5500. Thanks Akshat’s help for the openr set up 🙂

1. Set up the private insecure registry on your server
Refer as follow:
https://docs.docker.com/registry/deploying/
https://xrdocs.io/application-hosting/tutorials/2017-02-26-running-docker-containers-on-ios-xr-6-1-2/#private-insecure-registry
[root@nso ~]# nano /etc/yum.repos.d/docker.repo
[root@nso ~]# yum install docker-engine
[root@nso ~]# systemctl start docker
[root@nso ~]# docker run -d -p 5000:5000 --restart=always --name registry registry:2
[root@nso ~]# docker pull akshshar/openr-xr
[root@nso ~]# docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
c4636568f48a registry:2 "/entrypoint.sh /e..." 6 minutes ago Up 6 minutes 0.0.0.0:5000->5000/tcp registry

[root@nso ~]# docker tag akshshar/openr-xr 10.75.58.72:5000/openr-xr
[root@nso ~]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE

[root@nso ~]# docker push 10.75.58.72:5000/openr-xr
The push refers to a repository [10.75.58.72:5000/openr-xr]
Get https://10.75.58.72:5000/v1/_ping: http: server gave HTTP response to HTTPS client
[root@nso ~]#
2. Add follow at “/etc/sysconfig/docker”
After changing the docker opts, please wait some seconds, docker will auto restart.
DOCKER_OPTS=" --insecure-registry 10.75.58.72:5000"

When we want to collect some show information by Telemetry, we will face the 1st question that how to find the correct/resolved sensor path. The first step often traps us. Is there any good way to easily find the sensor path? The answer is “Yes”. I had summarized a way that can help you quickly find the sensor path.
Before read the article，there is a file that mapping between YANG and Sensor Path in XR, you can check by keyword(e.g fan, cpu and so on) first, if not found, then check my article.

去年年初，为了体验4k的“塞尔达传说-旷野之息”，我升级了我的电脑，并在18年不断完善，目前经过optane加速的4T硬盘，速度提升非常显著，很是喜欢。但电脑里有些录音，以及家庭照片，想随时观看，而不想开电脑，另外也起到备份的作用（数据无价），所以一直在考虑采购一台NAS，但感觉现在的NAS及配件（硬盘）功能比较弱（其实就是没米。。。），所以就考虑利用现有资源，把1T的闲置移动硬盘挂载到 WRT1200路由器下，这样 Win/Mac/手机 通过sshfs/samba远程挂载目录，这样可以体验简易NAS，等时机成熟了再考虑NAS，此篇主要总结如何挂载移动硬盘，由于环境版本的不同，总结中的内容可能跟读者遇到的会有少许差异，如遇到问题，可自行google或baidu
有时候通过LEDE的luci直接挂载不起作用，也弄不明白为啥，所以还是CLI最靠谱。另外在openwrt里，移动硬盘的格式最好是ext3或ext4，这样效果高，问题少。另外就是最开始我想用sshfs，但后来发现windows访问sshfs效果非常不好，所以对于windows，就换回了samba服务器，速度不错，可以达到平均60MB/s 上下
另外Samba配置，可以参考我之前的文章 Deploy Samba on OpenWRT
1. 国内更新源，这样就可以随便更新软件了
