5. Customising your instance

Customising your instance is the most complicated part of creating a custom elastic image. You need to install the packages that are prerequisites for Bamboo onto your instance (if you didn't choose the Elastic Bamboo stock images as your base AMI), add your customisations, deploy Bamboo onto your instance and set up an EC2 environment on your instance.

5.1 Bamboo 前提条件パッケージのインストール

If you selected Atlassian's AMI as your base AMI in '2. Selecting an Existing AMI', you can skip this step and go to '5.2 Adding Customisations' as this image has been pre-configured for Bamboo. If you have selected a different AMI, you will need to install the following packages onto your instance using the commands shown below:

Amazon EC2 API ツール

wget http://s3.amazonaws.com/ec2-downloads/ec2-api-tools.zip
unzip ec2-api-tools.zip
mv ec2-api-tools-* /opt/ec2-api-tools

注: ディストリビューションにすでに ec2-api-tools パッケージが含まれている場合は、代わりにそれをインストールできます。

Java JRE

You need to install JRE (or JDK) on your instance to be able to run the agent. The preferred way of doing this is to install a package that came with your distribution. For a list of supported JREs, see supported platforms.

5.2 Adding user customisations to your instance

Adding your own customisations is quite a simple process, once you have made it this far.

To add user customisations to your instance:

  1. Log into your elastic instance (as previously described in '4. Accessing your Instance').
  2. Once you have logged into your elastic instance, you can treat it as a standalone machine and install anything you want. For example, if you want to install Tomcat on an Ubuntu instance you would run 'sudo apt-get install tomcat6', configure it, ensure that your startup scripts are in place, etc, just as you would when installing Tomcat on a standalone machine.
    (warning)Please note however, you cannot customise the operating system of a running instance. If you want to create an instance with a customised operating system (e.g. Ubuntu), you will need to select an AMI with that operating system installed (as previously described in '2. Selecting an Existing AMI').
  3. Everything that you install will be saved in snapshot image created at the end of these instructions (see '6. Creating an Image of your Customised Instance'). Any instances started from this image will have all of your user customisations automatically installed.

5.3 Bamboo をインスタンスにデプロイする

Once you have installed the Bamboo pre-requisites on you instance and added your customisations, you can deploy Bamboo elastic bootstrap files onto your instance.

5.3.1 Bamboo ユーザーを作成する

最初に、次のコマンドを実行してインスタンス上に「bamboo」ユーザーを作成する必要があります。

useradd -m bamboo

5.3.2 エージェントのインストーラーをインスタンスにダウンロードする

Then, install Bamboo Agent binaries as described below. In this case we're using image version 2.2, you should use the latest version available at https://maven.atlassian.com/content/repositories/atlassian-public/com/atlassian/bamboo/atlassian-bamboo-elastic-image/.

imageVer=2.2
wget https://maven.atlassian.com/content/repositories/atlassian-public/com/atlassian/bamboo/atlassian-bamboo-elastic-image/${imageVer}/atlassian-bamboo-elastic-image-${imageVer}.zip
mkdir -p /opt/bamboo-elastic-agent
sudo unzip -o atlassian-bamboo-elastic-image-${imageVer}.zip -d /opt/bamboo-elastic-agent
sudo chown -R bamboo /opt/bamboo-elastic-agent
sudo chmod -R u+r+w /opt/bamboo-elastic-agent

5.4 インスタンス設定

At this stage, you should have a customised instance with Bamboo deployed onto it. The last step in creating a customised instance is to set up an EC2 environment on your instance. Carry out the following steps to set this up:

  1. インスタンス上で次のコマンドを実行して、bamboo ユーザー ディレクトリの権限を設定します。

    chown -R bamboo:bamboo /home/bamboo/

  2. パス変数を設定する
    インスタンスの /mnt ディレクトリに profile.sh ファイルを作成します。このファイルには、以下に示すように、Elastic Bamboo の既定のパス設定が含まれています。

    export JAVA_HOME=<path to JRE used to start the agent>
export EC2_HOME=<location of your EC2 tools installation>
export EC2_PRIVATE_KEY=/root/pk.pem
export EC2_CERT=/root/cert.pem
export PATH=/opt/bamboo-elastic-agent/bin:$EC2_HOME/bin:$JAVA_HOME/bin:$M2_HOME/bin:$MAVEN_HOME/bin:$ANT_HOME/bin:$PATH

    If all of the tools on this page were installed in recommended locations, no changes are required. Otherwise, you can update the file as required.
    Once profile.sh is correctly customised for your instance, you need to copy it to the /etc/profile.d directory by running the following command on your instance in the /mnt directory:

    mv profile.sh /etc/profile.d/bamboo.sh

  3. Bamboo エージェントの自動起動を設定する
    インスタンスの起動時に Bamboo エージェントが自動的に起動するようにインスタンスを設定する必要があります。これは、/etc/rc.local ファイルに Bamboo の rc.local ファイルを調達 (source) することで実現できます。

    . /opt/bamboo-elastic-agent/etc/rc.local

    必ず /etc/rc.local の「exit 0」行の前にこの行を追加してください。

  4. 最後の設定とクリーンアップ
    最後に、次のコマンドを実行して Bamboo のようこそ画面を作成し、インスタンスのキーをクリーンアップします。

    cp /opt/bamboo-elastic-agent/etc/motd /etc/motd
echo bamboo-<x.x.x>  >> /etc/motd
rm -f /root/firstlogin /etc/ssh/ssh_host_da_key /etc/ssh/ssh_host_dsa_key.pub
/etc/ssh/ssh_host_key /etc/ssh/ssh_host_key.pub /etc/ssh/ssh_host_rsa_key
/etc/ssh/ssh_host_rsa_key.pub /root/.ssh/authorized_keys
touch /root/firstrun

    <x.x.x> は実行している Bamboo のバージョン (4.1.2 など) です。

  5. Now, follow the instructions from section "Creating an image of your Customised Instance" to create an AMI.

  6. Bamboo からイメージを起動します。エージェントが起動し、必要なすべてのデータを EC2 インスタンスにダウンロードします。
  7. /opt/bamboo-elastic-agent/bin/prepareInstanceForSaving.sh を実行します。
  8. Now, follow the instructions from section "Creating an image of your Customised Instance" to create an AMI. That's it, the newly created AMI contains everything you need to start Bamboo Agents.

注: 最初に Bamboo からインスタンスを起動した場合は、ステップ 5 と 6 の代わりに以下を実行するだけで済みます。

su -c /opt/bamboo-elastic-agent/bin/bamboo-elastic-agent - bamboo
