フルスタックエンジニアを目指して

いろいろやってみるブログ

これまで触って来たインフラ技術

なんとなく思い立ったので書き出してみる。

 

L2/L3 Network(Cisco/Quagga)

Firewall(Juniper Netscreen/SSG/SRX)

Load Balancer(F5/A10)

IPS/IDS(TippingPoint)

Next-generation Firewall(Paloalto)

UTM(Fotigate)

DNS(AD/BIND)

Proxy/Web Filtering(Squid/i-FILTER/Paloalto/Fotigate/Z-Scaler)

Mail(Sendmail/Postfix/ExchangeOnline+Protection/Mail Security.cloud)

Account(Active Directory/LDAP)

Virtualization(VMware ESXi/Xen/Docker)

IaaS(AWS/GCP/Azure)

WAN(IP-VPN/Internet-VPN/WAN Optimization/ExpressRoute/AWS DirectConnect)

 

4年でよく触ったなとも思うし、最近全然機械さわれてないこと考えるともっと触れるなとも思う。

 

最近、今後の方向性どうしたものかと悩ましい。

Let's note のキーボード配列(Fn⇔Ctrl)を変更する

  • はじめに
  • ステップ1:高速スタートアップ を無効にする。
  • ステップ2:BIOS設定画面からキー配列を変更する。

Google Cloud Shell を使ってみる

Google Cloud Shell は Google Cloud Platform に登録すると使える Linux 環境です。Webブラウザ経由でのアクセスなので便利そうです。

Google Cloud Platform(GCP) への登録

登録には住所やクレジットカード番号が必要です。現在12ヶ月間(300ドル)の無料トライアル期間をやっているので、そちらを利用します。

触ってみる

ログインすると help を入力するといいよ、と言われたのでとりあえず打ってみます。

Welcome to Cloud Shell! Type "help" to get started.
user@machine-id:~$ help

Welcome to Google Cloud Shell, a tool for managing resources hosted on Google Cloud Platform!
The machine comes pre-installed with the Google Cloud SDK and other popular developer tools.

Your 5GB home directory will persist across sessions, but the VM is ephemeral and will be reset
approximately 20 minutes after your session ends. No system-wide change will persist beyond that.

Type "gcloud help" to get help on using Cloud SDK. For more examples, visit
https://cloud.google.com/shell/docs/quickstart and https://cloud.google.com/shell/docs/examples

Type "cloudshell help" to get help on using the "cloudshell" utility.  Common functionality is
aliased to short commands in your shell, for example, you can type "dl <filename>" at Bash prompt to
download a file. Type "cloudshell aliases" to see these commands.

Type "help" to see this message any time. Type "builtin help" to see Bash interpreter help.

5GB の保存領域が使えるようです。また、セッション断から20分経過すると環境がリセットされるそうです。ある意味検証環境には最適ですね。
GCP用のSDKもここから使えるようです。

PATH通ってるところを覗いて、何のコマンドが使えるのか確かめてみます。

Hello from Docker!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
    (amd64)
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash

他にもインストールとか普通にできるので、結構楽しめそうなおもちゃが出来上がりました。

Google Chromeのインストール

Qiita の記事通りに Google Chrome をインストールしてみます。

Complete!

Google Chrome がインストールできました。

[root@22a4bea55835 src]# google-chrome --version
Google Chrome 64.0.3282.140

Google Chrome を実行すると何やら怒られました。

[root@22a4bea55835 src]# google-chrome
[530:530:0204/150518.065349:ERROR:zygote_host_impl_linux.cc(90)] Running as root without --no-sandbox is not supported. See https://crbug.com/638180.

--no-sandboxをつけて再実行するとうまくいきました。

実行結果

このように、Screenshotが撮れました。

Google Chromeで取得したスクリーンショット

(2018/2/4追記) 実行コマンドは以下の通り。

[root@3b7c2354d4cc share]# google-chrome --no-sandbox --headless --disable-gpu --screenshot="screenshot_$(date +"%Y%m%d").png" --window-size=1280,1080 https://www.yahoo.co.jp/

--screenshot=でファイル名が指定できるので、日付でファイル名をつけることも可能です。
