ECS-CLI卡住了创建容器

Question

我正在尝试使用ecs-cli命令行在AWS上获得一个工作的Docker环境。

我有一个使用Dockerfiles、docker-compose.yml、一个.env文件和一个entrypoint.sh脚本的工作本地Docker环境。容器是一个运行PHP和一系列扩展的apache webserver以及一个MySQL DB。

骨架文件结构是这样的：

./db <-- mounted by db container for persistence
./docker
./docker/database
./docker/database/Dockerfile
./docker/database/dump.sql
./docker/webserver
./docker/webserver/apache-config.conf
./docker/webserver/Dockerfile
./docker/webserver/entrypoint.sh
./docker-compose.yml
./web <!-- mounted by web server, contains all public web code

FROM mysql:5.6
ADD dump.sql /docker-entrypoint-initdb.d

FROM php:5.6-apache
RUN apt-get update 
RUN curl -sL https://deb.nodesource.com/setup_8.x | bash -
RUN apt-get install -y zlib1g-dev nodejs gdal-bin
RUN npm install -g topojson
RUN docker-php-ext-install mysql mysqli pdo pdo_mysql zip
RUN pecl install dbase
RUN docker-php-ext-enable dbase
COPY apache-config.conf /etc/apache2/sites-enabled/000-default.conf
RUN a2enmod rewrite headers
RUN service apache2 restart
COPY entrypoint.sh /entrypoint.sh
RUN chmod 0755 /entrypoint.sh
ENTRYPOINT ["/entrypoint.sh", "apache2-foreground"]

./docker/webserver/entrypoint.sh#！/bin/sh

mkdir /var/www/html/maps
chown www-data /var/www/html/maps
chgrp www-data /var/www/html/maps
exec "$@"

下面是docker-compose.yml

version: '2'

services:
  webserver:
    image: ACCOUNT_NUMBER.dkr.ecr.eu-west-1.amazonaws.com/project/project-webserver
    ports:
      - "8080:80"
    volumes:
      - ./web:${APACHE_DOC_ROOT}
    links:
      - db
    environment:
      - HTTP_ROOT=http://${DOCKER_HOST_IP}:${DOCKER_HOST_PORT}/
      - PHP_TMP_DIR=${PHP_TMP_DIR}
      - APACHE_LOG_DIR=${APACHE_LOG_DIR}
      - APACHE_DOC_ROOT=${APACHE_DOC_ROOT}/
      - SERVER_ADMIN_EMAIL=${SERVER_ADMIN_EMAIL}
      - MYSQL_USER=${MYSQL_USER}
      - MYSQL_PASSWORD=${MYSQL_PASSWORD}
      - MYSQL_DATABASE=${MYSQL_DATABASE}
    env_file: .env

  db:
    user: "1000:50"
    image: ACCOUNT_NUMBER.dkr.ecr.eu-west-1.amazonaws.com/project/project-database
    ports:
      - "4406:3306"
    volumes:
      - ./db:/var/lib/mysql
    environment:
      - MYSQL_ROOT_PASSWORD=${MYSQL_ROOT_PASSWORD}
      - MYSQL_USER=${MYSQL_USER}
      - MYSQL_PASSWORD=${MYSQL_PASSWORD}
      - MYSQL_DATABASE=${MYSQL_DATABASE}
    env_file: .env

要构建引用在那里的映像,请执行以下操作：

docker/database$docker build-t account_number.dkr.ecr.eu-west-1.amazonaws.com/project/project-database。

让docker登录到ECR（运行docker login命令echod到std-out）：

$AWS ecr get-login--no-include-email

推送图片：

$Docker推送account_number.dkr.ecr.eu-west-1.amazonaws.com/project/project-webserver

$Docker推送account_number.dkr.ecr.eu-west-1.amazonaws.com/project/project-database

$aws ecr描述-图像-存储库-名称项目/项目-数据库

看起来都很好。

我想我需要弄清楚为什么这些容器没有被初始化，但是我应该在哪里寻找，更好的是，下一步我需要做什么来使它工作？

如果有其他人在这里漂泊，那么缺少的咒语是$ecs-cli compose create，它从您的compose文件构建一个ECS任务定义（假设它是兼容的...）

和$ecs-cli compose run,它们将在远程EC2计算机上构建和运行容器。

ssh'ing到远程机器并执行“docker ps-a”应该会显示容器正在运行。或者“Docker logs[container_name]”查看错误所在...
