ECS AnywhereがGAしました。おめでとうございます。
早速ですが、やってみました。
環境
Raspberry Pi 4 (8GB)
OS: Ubuntu 20.04(64bit)
OSクリーンインストール状態から始めます。
手順
cgroupsの有効化
/boot/firmware/cmdline.txtの1行目の末尾にcgroup_enable=memory cgroup_memory=1を追加します。
/boot/firmware/cmdline.txt
- net.ifnames=0 dwc_otg.lpm_enable=0 console=serial0,115200 console=tty1 root=LABEL=writable rootfstype=ext4 elevator=deadline rootwait fixrtc
+ net.ifnames=0 dwc_otg.lpm_enable=0 console=serial0,115200 console=tty1 root=LABEL=writable rootfstype=ext4 elevator=deadline rootwait fixrtc cgroup_enable=memory cgroup_memory=1
保存したら再起動します。
Externalインスタンスの登録
マネジメントコンソールで行います。
まずはクラスターを作成します。
ネットワーキングのみを選択
クラスター名を入力。VPCは作成しなくてOKです。
クラスターができました。
ECSインスタンスタブを選択し、Externalインスタンスの登録ボタンをクリック
特に入力は変えなくてOKです。
するとコマンドが表示されるのでコピーします。
コピーしたコマンドをRaspberry Piで実行するのですが、root権限が必要なので、&& bashのところを&& sudo bashに置き換えて実行します。
RaspberryPi
curl --proto "https" -o "/tmp/ecs-anywhere-install.sh" "https://amazon-ecs-agent.s3.amazonaws.com/ecs-anywhere-install-latest.sh" && sudo bash /tmp/ecs-anywhere-install.sh --region "ap-northeast-1" --cluster "ECSAnywhere" --activation-id "xxxxxxxx" --activation-code "xxxxxxxx"
すると、以下のものがすべてインストールされます。一発です。
- AWS Systems Manager Agent
- Amazon ECS コンテナエージェント
- Docker
コンソール出力
ubuntu@ubuntu:~$ curl --proto "https" -o "/tmp/ecs-anywhere-install.sh" "https://amazon-ecs-agent.s3.amazonaws.com/ecs-anywhere-install-latest.sh" && sudo bash /tmp/ecs-anywhere-install.sh --region "ap-northeast-1" --cluster "ECSAnywhere" --activation-id "xxxxxxxx" --activation-code "xxxxxxxx"
