■CodeCommitの作成
- git互換のソースリポジトリであるCodeCommitを作成
cmd
aws codecommit create-repository \
--repository-name ContainerHandsOn \
--repository-description "ContainerHandsOn" \
--tags "key=Name,value=ContainerHandsOn"
result
{
"repositoryMetadata": {
"accountId": "123456789012",
"repositoryId": "45fe4e7e-d7bb-4e06-9ee4-9d959888be4b",
"repositoryName": "ContainerHandsOn",
"repositoryDescription": "ContainerHandsOn",
"lastModifiedDate": 1663244011.08,
"creationDate": 1663244011.08,
"cloneUrlHttp": "https://git-codecommit.ap-northeast-1.amazonaws.com/v1/repos/ContainerHandsOn",
"cloneUrlSsh": "ssh://git-codecommit.ap-northeast-1.amazonaws.com/v1/repos/ContainerHandsOn",
"Arn": "arn:aws:codecommit:ap-northeast-1:123456789012:ContainerHandsOn"
}
}
■CodeCommitリポジトリのクローン
- git cloneでリポジトリをcloneします、中身は空です
cmd
cd ~/environment/
git clone https://git-codecommit.ap-northeast-1.amazonaws.com/v1/repos/ContainerHandsOn
result
Cloning into 'ContainerHandsOn'...
warning: You appear to have cloned an empty repository.
■資材の準備
- 事前に作成した資材をgit管理ディレクトリにcopyします
cmd
cd ~/environment/ContainerHandsOn
cp -p ../Dockerfile ./
cp -pr ../src ./
ls -lR
result
.:
total 8
-rw-rw-r-- 1 ec2-user ec2-user 47 Sep 15 12:01 Dockerfile
drwxrwxr-x 2 ec2-user ec2-user 4096 Sep 15 12:01 src
./src:
total 4
-rw-rw-r-- 1 ec2-user ec2-user 190 Sep 15 12:01 index.php
■buildspec.ymlの新規作成
- CodeBuildの仕様を記述したファイルを作成します
cmd
cd ~/environment/ContainerHandsOn
cat << EOF > buildspec.yml
version: 0.2
phases:
install:
runtime-versions:
docker: 20
pre_build:
commands:
- echo Logging in to Amazon ECR...
- docker version
- aws ecr get-login-password --region ap-northeast-1 | docker login --username AWS --password-stdin ${AccountID}.dkr.ecr.ap-northeast-1.amazonaws.com
- RepositoryUri=${AccountID}.dkr.ecr.ap-northeast-1.amazonaws.com/jaws-days-2022/container-hands-on
- ImageTag=\$(echo \$CODEBUILD_RESOLVED_SOURCE_VERSION | cut -c 1-7)
build:
commands:
- echo Build started on \`date\`
- echo Building the Docker image...
- docker build -t jaws-days-2022/container-hands-on .
- docker tag jaws-days-2022/container-hands-on:latest \${RepositoryUri}:latest
- docker tag jaws-days-2022/container-hands-on:latest \${RepositoryUri}:\${ImageTag}
- printf '{"Version":"1.0","ImageURI":"%s"}' \${RepositoryUri}:\${ImageTag} > imageDetail.json
post_build:
commands:
- echo Build completed on \`date\`
- echo Pushing the Docker image...
- docker push \${RepositoryUri}:latest
- docker push \${RepositoryUri}:\${ImageTag}
artifacts:
files: imageDetail.json
EOF
result
（なし）
■buildspec.ymlの確認
cmd
cd ~/environment/ContainerHandsOn
ls -l buildspec.yml
result
-rw-rw-r-- 1 ec2-user ec2-user 1193 Sep 15 12:14 buildspec.yml
■appspec.ymlの新規作成
- CodeDeployの仕様を記述したファイルを作成します
- <TASK_DEFINITION>と記載されている箇所は後ほどCodePipelineで更新します
cmd
cd ~/environment/ContainerHandsOn
cat << EOF > appspec.yml
version: 0.0
Resources:
- TargetService:
Type: AWS::ECS::Service
Properties:
TaskDefinition: "<TASK_DEFINITION>"
LoadBalancerInfo:
ContainerName: "ContainerHandsOn"
ContainerPort: "80"
EOF
result
（なし）
■appspec.ymlの確認
cmd
cd ~/environment/ContainerHandsOn
ls -l appspec.yml
result
-rw-rw-r-- 1 ec2-user ec2-user 240 Sep 15 12:14 appspec.yml
■taskdef.jsonの新規作成
- ECS Taskの仕様を記述したファイルを作成します
- 前半のハンズオンで作成した内容を出力しています
cmd
aws ecs describe-task-definition \
--task-definition ContainerHandsOn:${RevisionNo} \
--query taskDefinition > taskdef.json
result
（なし）
■taskdef.jsonの変更
以下の変更を行います
<変更前>
"image": "123456789012.dkr.ecr.ap-northeast-1.amazonaws.com/jaws-days-2022/container-hands-on:latest"
<変更後>
"image": "<IMAGE_NAME>"
<IMAGE_NAME>は後述のCodePipelineにて、最新のImage URIに置換する処理が組み込まれます
cmd（変更前確認）
cd ~/environment/ContainerHandsOn
grep '"image":' taskdef.json
result（変更前確認）
"image": "123456789012.dkr.ecr.ap-northeast-1.amazonaws.com/jaws-days-2022/container-hands-on:latest",
cmd（変更処理＆変更後確認）
cd ~/environment/ContainerHandsOn
sed -i -e 's/\"image\".*/\"image\": \"<IMAGE_NAME>\",/g' taskdef.json
grep '"image":' taskdef.json
result
"image": "<IMAGE_NAME>",
■CodeCommitへのPush
- 作成したファイルをCodeCommitへPushし格納します
cmd
cd ~/environment/ContainerHandsOn
git config --global user.name "Your Name"
git config --global user.email you@example.com
git add -A
git commit -m "first commit"
git push origin master
result
[master (root-commit) 15052c6] first commit
