В настоящее время я работаю над проектом микросервиса с использованием docker-compose. Итак, я добавлял проверки работоспособности в свои контейнеры. Но, кроме mysql, все остальное остается нездоровым, но я не знаю почему.

Вот мой файл docker-compose.yml.

 version: "3"
services:
  zookeeper:
    image: wurstmeister/zookeeper
    container_name: zookeeper
    ports:
      - "2181:2181"

  kafka:
    image: wurstmeister/kafka
    container_name: kafka
    ports:
      - "9092:9092"
    environment:
      KAFKA_ADVERTISED_HOST_NAME: 52.78.52.254
      KAFKA_ZOOKEEPER_CONNECT: zookeeper:2181
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
    depends_on:
      - zookeeper

  mysql:
    image: mysql
    container_name: mysql
    ports:
      - "3306:3306"
    volumes:
      - ./data/mysql:/var/lib/mysql:rw
    environment:
      - MYSQL_ROOT_PASSWORD=dnjscksdn98@
      - MYSQL_DATABASE=explanet_dev
      - MYSQL_USER=alex
      - MYSQL_PASSWORD=dnjscksdn98@
    healthcheck:
      test: ["CMD", "mysqladmin", "ping", "-h", "mysql", "-u$MYSQL_USER", "-p$MYSQL_ROOT_PASSWORD" ]
      interval: 30s
      timeout: 10s
      retries: 3

  api-gateway:
    container_name: api-gateway
    ports:
      - "80:80"
    build:
      context: ./api-gateway
      args:
        ENVIRONMENT: dev
      dockerfile: Dockerfile
    healthcheck:
      test: [ "CMD", "curl", "-f", "http://api-gateway/health-check" ]
      interval: 30s
      timeout: 10s
      retries: 3
    depends_on:
      - mysql

  chatting-service:
    container_name: chatting-service
    ports:
      - "8080:8080"
    build:
      context: ./chatting-service
      args:
        ENVIRONMENT: dev
      dockerfile: Dockerfile
    healthcheck:
      test: [ "CMD", "curl", "-f", "http://chatting-service:8080/health-check" ]
      interval: 30s
      timeout: 10s
      retries: 3
    depends_on:
      - mysql
      - kafka
      - api-gateway
 

И если я введу docker inspect ${any container name} , это будет выглядеть так в State .

                    }
                ]
            }
 

Мой java-файл Dockerfile выглядит следующим образом.

 FROM adoptopenjdk/openjdk11:alpine-jre
COPY build/libs/base-service-0.0.1-SNAPSHOT.jar base-service.jar
ARG ENVIRONMENT
ENV SPRING_PROFILES_ACTIVE=${ENVIRONMENT}
ENTRYPOINT ["java", "-jar", "base-service.jar"]
 

В настоящее время я работаю на сервере Ubuntu 20.04. Есть ли какие-либо решения?

Привет, сообщение об ошибке довольно четкое, вы не можете запустить curl для проверки работоспособности, потому что он не включен в базовый образ, который вы используете, вам необходимо его установить.
Пример для alpine images
