This is my first attempt at trying multi-cloud deployment with CoreOS. Not so famous cloud providers such as IDCF Cloud, it is very important to have cloud interoperabilities. With help of CoreOS and fleet, it would be possible to try out CoreOS on IDCF Cloud and deploy to any other clouds in production. What is more important is that without CloudFormation or OpenStack Heat, it would be possible to describe a template of muptiple instances also.

This week ASUS Zenfone teaser site opened in Japan. It seemes that the picture is a Zenfone 6 as I overlay my one to. I am also interested in Nexus 6, Zenfone 6 has a high cost performance at under half price,My impression on Zenfone 6 after 2 months is mostly good. I am not so concern with tech specs that happy with middle range.

Two weekes have already passed since I ordered a Spark Core to Maker Shed. It has not delivered yet. Because I cannot wait I sent the another order for Getting Started Kit with Arduino to Amzaon.The Spark Core uses Arduino programming language so it will be good for me to learn Arduino beforehand.

To deal with a data volume contaner in fleet unit file on staging IDCF Cloud, my first attempt was very naive. It colud work just incase it was the first time. So I rethinked building data volume container. I don't understand this is correct way, but it works when there exists a data volume container already and using that container.

Previously I deployed plain MoinMoin CoreOS instance on IDCF Cloud. Next thing should I do is to serve with data volume contaner. Without fleet it is easy to backup and restore using docker-backup. Considering how difficult it is to write fleet unit files for me, it would take time to practice. I think I'm ready to face the day.

I backuped MoinMoin pages archives to IDCF Object Storage. Before deploying to the production environment on DigitalOcean, I prepared CoreOS instance on IDCF Cloud for staging environment. This is very first time I wrote MoinMoin installing as a fleet unit file.

I use serveral computers for programming which is a Mac Book Pro or a Windows machine or a Chromebook. In such a multiple environment it is very useful using Cloud IDE, so I have been using Nitrous.IO. On OSX I have to use Nitrous Desktop, because otherwise I could not type any Japanese characters. It would not be helpful if I run an IDE from Chrome App Launcher or visit directly on my Dashboard with Chrome Browser.If Secure Shell Chorme App were enable to type Japanese characters it woulde be Chromebook as perfect develop environment combined with Nitrous.IO.

I used to evaluate ssh-agent output each time when I open new shells with byobu and tmux windows. It's because ssh-agent envorinment variables are not passed overa to new shell. I found that more than 10 ssh-agent processes are running. After Googling I reached a great post titled Understanding ssh-agent and ssh-add.

I forked docker-lloyd repo for using with IDC Frontier Object Storage and store image in masato/docker-lloyd. It' helpful for me to do scheduling backup statefull containers.

WordPressのデータボリュームコンテナを作成したときはcommitしてもvolumeに指定したディレクトリの中身が保存されずに不思議に思いました。MoinMoinのバックアップで初めは挫折したdocker-backupも、ようやくGoのコードを読んで使えるようになりました。データボリュームコンテナの意味がはじめて理解できるようになると、なるほどdisposableコンテナの運用には必須の機能です。
