Docker Compose

NOTE: 新版指令改成 docker compose。

NOTE: 服務一旦佈署完成，docker-compose.yml 的路徑如果有變更，就不能繼續使用指令 docker-compose 來管理 container，不過已經啟動的服務運行不會影響，但關閉後就無法再被啟動。

新增與啟動所有應用服務

# For all services
docker-compose up -d

# For specified service
docker-compose up -d <service-name>

Build the image of the service

docker-compose build <service-name>
docker-compose up --rebuild <service-name>

目前的應用服務狀態

docker-compose ps

重啟所有應用服務但不要刪除所屬 container

docker-compose stop
docker-compose start

如果 container 屬性沒有異動，只是所屬的服務需要重啟載入新設定，可以使用這。

停止所有應用服務並刪除所屬 container

# For all services
docker-compose down

# For a specified service
docker-compose stop <service-name>
docker-compose rm -f <service-name>

NOTE:

- 如果有修改 docker-compose.yml，必須使用 down 關閉服務後，用 up -d 重新啟動。

- 停止服務後，重新啟動只能使用 docker-compose up -d

檢視服務啟動失敗的日誌

docker-compose logs

執行某個應用服務的特定程序

docker-compose exec <service-name> sh -c "pwd"

環境變數檔 --env-file

docker compose --env-file .env up -d

Labels

    用途：如果要管理上百個 continers 時，標籤功能可用客製標籤來標記 container，以便日常管理維護。 用法：--label my-label=my-value  技巧：標籤的命名方式建議使用 com.myorg.XX 的格式，myorg 替換成組織的代名。

    docker-compose.yml

    services:
  web:
    image: myorg/web:2.3.1
    labels:
      com.myorg.project: payment-api
      com.myorg.environment: production
      com.myorg.team: billing
      com.myorg.service-type: backend
      com.myorg.version: 2.3.1
  redis:
    image: redis:6.2
    labels:
      com.myorg.project: payment-api
      com.myorg.environment: production
      com.myorg.team: billing
      com.myorg.service-type: cache
      com.myorg.version: "6.2"

    使用 --filter 來過濾

    docker ps --filter "label=com.myorg.project=payment-api"
docker inspect --format='{{json .Config.Labels}}' $(docker ps -q)

     

    docker-compose.yml

    .env

    敏感性的資料如密碼、API Token，建議使用 .env 檔案來儲存。

    .env

    MYSQL_ROOT_PASSWORD=supersecurepassword
MYSQL_DATABASE=appdb
MYSQL_USER=appuser
MYSQL_PASSWORD=anothersecurepassword
