ASUS RT-AC88U sous Asuswrt, compagnon idéal de votre domotique

En France, on a l’avantage d’avoir nos box ADSL qui sont de vraies couteaux suisses. Mais cela veut aussi dire que si l’on change de FAI, on refait son réseau. Ou bien par exemple qu’on ne peut pas tout gérer sur son routeur. Cela fait quelques années que j’étais équipé d’un Netgear passé sous OpenWRT. Et là depuis 6 mois, c’est un Asus RT-AC88Uqui a pris le relais, fourni sous Asuswrt. Car…

Dokku is an extensible, open source Platform as a Service that runs on a single server of your choice. If you ever used Heroku, then think of it as your hosted version of Heroku. You can have docker based Platform as a Service running on a single server. In this guide, we will cover the installation of Dokku PaaS on Ubuntu 20.04|18.04 Linux System. As of this article update the supported operating systems are: Ubuntu 16.04/18.04/20.04 x64 Debian 9+ x64 With CentOS 7 still experimental Installing Dokku on Ubuntu – Pre-requisites Installed and updated Ubuntu 20.04|18.04 system Docker Engine At least 1GB of system memory Server with FQDN set – Can be on DNS or /etc/hosts There are two ways of installing Dokku on Ubuntu 20.0418.04: Using bootstrap script Installing from Dokku apt repository We will consider both methods to install Dokku on Ubuntu 20.04|18.04 Linux server. I recommend installing Dokku from the apt repository so that you can have a view of what’s happening. Set system hostname using the hostnamectl command: $ sudo hostamectl set-hostname dokku.computingforgeeks.com Ensure your system is updated and upgraded: sudo apt update sudo apt upgrade -y sudo reboot Method 1: Install Dokku on Ubuntu 20.04|18.04 from apt repository Dokku packages are available on packagecloud.io dokku repository. Start by importing repository GPG key to trust packages: sudo apt update sudo apt install -y apt-transport-https wget -nv -O - https://packagecloud.io/dokku/dokku/gpgkey | sudo apt-key add - Key importation output: 2020-10-08 19:40:09 URL:https://d28dx6y1hfq314.cloudfront.net/505/623/gpg/dokku-dokku-FB2B6AA421CD193F.pub.gpg?t=1602179109_89e21c60fdf77e8ab2181ba23ae0dc910985dfbb [3937/3937] -> "-" [1] OK Add the repo using the commands below: OS_ID="$(lsb_release -cs 2>/dev/null || echo "bionic")" echo "deb https://packagecloud.io/dokku/dokku/ubuntu/ $OS_ID main" | sudo tee /etc/apt/sources.list.d/dokku.list Then update system package list: sudo apt update Step 1: Install Docker Engine on Ubuntu 20.04|18.04 You can install either stable release of Docker or edge release, both are supported by Dokku. wget -nv -O - https://get.docker.com/ | sudo bash - Add your user account to docker group: sudo usermod -aG docker $USER newgrp docker This is unattended installation, wait for it to complete then confirm docker engine version installed: $ docker version Client: Docker Engine - Community Version: 19.03.13 API version: 1.40 Go version: go1.13.15 Git commit: 4484c46d9d Built: Wed Sep 16 17:02:52 2020 OS/Arch: linux/amd64 Experimental: false Server: Docker Engine - Community Engine: Version: 19.03.13 API version: 1.40 (minimum version 1.12) Go version: go1.13.15 Git commit: 4484c46d9d Built: Wed Sep 16 17:01:20 2020 OS/Arch: linux/amd64 Experimental: false containerd: Version: 1.3.7 GitCommit: 8fba4e9a7d01810a393d5d25a3621dc101981175 runc: Version: 1.0.0-rc10 GitCommit: dc9208a3303feef5b3839f4323d9beb36df0a9dd docker-init: Version: 0.18.0 GitCommit: fec3683 Step 2: Install Dokku on Ubuntu 20.04|18.04 Once docker has been installed, you can proceed to install Dokku on your Ubuntu 20.04|18.04 LTS system. This is done by updating system packages and installing dokku package: sudo apt update sudo apt install dokku -y Dependencies installed through apt include: herokuish sshcommand plugn When asked whether to enable web configuration interface, answer yes Installation of dokku will also configure nginx for you and create a systemd service unit for managing the service.

Confirm: SSH Public key that you’ll use to access Dokku apps. Provide FQDN hostname for dokku to be used for apps URL Check Use virtualhost naming to have your apps deployed on Dokku with hostnames Then click “Finish Setup” button to finish Installation of Dokku on Ubuntu 20.04|18.04. Note that Once you save your settings, the web admin will self-terminate and you should be able to run or deploy to the Dokku installation. Upgrading Dokku on Ubuntu 20.04|18.04 To upgrade Dokku to the latest stable release, use dokku-update command: sudo dokku ps:stopall sudo apt update sudo apt install -qq -y dokku herokuish sshcommand plugn gliderlabs-sigil sudo sudo apt upgrade Upgrading Dokku with above command will not affect the running dokku and automates many of the upgrade instructions for you. If you would like to rebuild all applications after the upgrade, use: sudo dokku ps:rebuildall Installing Dokku Plugins Dokku provides a handful of Plugins to manage other functionalities. All are available on Dokku has official plugins. Installation of these plugins is done on the Dokku host as a root user or using a user account with sudo privileges.

See examples below: Install PostgreSQL  datastore service: sudo dokku plugin:install https://github.com/dokku/dokku-postgres.git Install MariaDB datastore plugin: sudo dokku plugin:install https://github.com/dokku/dokku-mariadb.git mariadb Deploying Apps to Dokku Now that you have a working Dokku installation on your Ubuntu 20.04|18.04 system, you can begin deployment of applications. You can read a comprehensive guide on deploying apps to Dokku. Conclusion Dokku is a free and open-source Docker-based PaaS that allows you to basically do the same things as Heroku on your own infrastructure (on-premises or cloud). It is easy to setup and use. If you have any challenges with the installation and configuration, let me know through the comment section.

Git Identity Manager - Gitのアカウント情報を切り替え

from http://www.moongift.jp/2018/06/git-identity-manager-git%e3%81%ae%e3%82%a2%e3%82%ab%e3%82%a6%e3%83%b3%e3%83%88%e6%83%85%e5%a0%b1%e3%82%92%e5%88%87%e3%82%8a%e6%9b%bf%e3%81%88/

Gitではユーザ名とメールアドレ��などを設定として保存しておきます。しかし、企業と個人でアカウントを切り替えている人にとっては不便です。間違って会社のアカウントで登録してしまって、慌てて削除したなんて経験がある人がいるかも知れません。

そこで使ってみたいのがGit Identity Managerです。複数のアカウント設定を簡単に切り替えられるソフトウェアです。

Git Identity Managerの使い方

アカウントの追加はaddを使います。名前、メールアドレス、SSHキーのパスはセットです。

git idm add jcool --name "Joe Cool" --email joe@example.com --key ~/.ssh/id_rsa

登録したら、listで登録内容を確認できます。

$ git idm list personal name=Atsushi email=atsushi@moongift.jp sshkey=~/.ssh/id_rsa sshcommand=ssh -i ~/.ssh/id_rsa -o IdentitiesOnly=yes -F /dev/null work name=Atsushi email=atsushi@moongift.jp sshkey=~/.ssh/id_rsa sshcommand=ssh -i ~/.ssh/id_rsa -o IdentitiesOnly=yes -F /dev/null

使う時には use を使います。

git idm use work

そうすると設定が変わっているのが分かります。

$ git config -l credential.helper=osxkeychain user.name=Atsushi user.email=moongift@gmail.com user.activeidm=personal

すぐに戻せます。

$ git config -l credential.helper=osxkeychain user.name=Atsushi user.email=atsushi@moongift.jp user.activeidm=work

企業で開発を行っている時に、アカウントをその企業のものとするケースはよくあります。しかし個人の開発もGitで行っていたら、その切り替えは手間に感じるでしょう。Git Identity Managerならば一瞬で切り替えられるのでとても簡単です。

Git Identity ManagerはShellスクリプト製のオープンソース・ソフトウェア（MIT License）です。

samrocketman/git-identity-manager: Git identity manager. It allows you to switch between git identities for user, name, and SSH private key used for authoring and publishing git commits.
