Question

我的Docker容器在OSX上构建良好：

Docker version 17.12.0-ce, build c97c6d6  
docker-compose version 1.18.0, build 8dd22a9

但不构建在Amazon Linux上：

Docker version 17.12.0-ce, build 3dfb8343b139d6342acfd9975d7f1068b5b1c3d3  
docker-compose version 1.20.1, build 5d8c71b

完整Dockerfile：

有谁知道可能导致这种差异的原因是什么？来自Docker的错误消息没有提供很多线索。我会非常感谢别人可以提供的任何想法！

为了解决这个问题，我按照@ MazelTov的建议，在我当地的OSX开发机器上构建容器，然后将图像发布到Docker Cloud，然后将这些图像下载到我的生产服务器（AWS EC2）上并运行图像

安装依赖项

我会尝试概述下面的步骤，以防他人帮助他人。请注意，这些步骤要求您在开发和生产计算机上安装docker和docker-compose。我使用gui安装程序安装Docker for Mac。

构建图像

编写Dockerfile和docker-compose.yml文件后，您可以使用docker-compose up --build构建图像。

将图像上传到Docker Cloud

构建图像后，您可以按照以下步骤将它们上传到Docker Cloud。首先，在Docker Cloud上创建一个帐户。

然后将您的Docker Cloud用户名存储在环境变量中（因此~/.bash_profile应包含export DOCKER_ID_USER='yaledhlab'（尽管使用您的用户名）。

接下来从您的开发者计算机登录您的帐户：

docker login

登录后，列出泊坞窗图片：

docker ps

这将显示如下内容：

CONTAINER ID        IMAGE                          COMMAND                  CREATED             STATUS              PORTS                      NAMES
89478c386661        yaledhlab/let-them-speak-web   "/bin/sh -c 'npm run…"   About an hour ago   Up About an hour    0.0.0.0:7082->7082/tcp     letthemspeak_web_1

890f7f1dc777        bitnami/tomcat:latest          "/app-entrypoint.sh …"   4 hours ago         Up About an hour    0.0.0.0:8080->8080/tcp     letthemspeak_tomcat_service_1
09d74e36584d        mongo                          "docker-entrypoint.s…"   4 hours ago         Up About an hour    0.0.0.0:27017->27017/tcp   letthemspeak_mongo_service_1

对于要发布到Docker Cloud的每个图像，请运行：

docker tag image_name $DOCKER_ID_USER/my-uploaded-image-name
docker push $DOCKER_ID_USER/my-uploaded-image-name

例如，要将mywebapp_web上传到Docker云上的用户帐户，您可以运行：

docker tag mywebapp_web $DOCKER_ID_USER/web
docker push $DOCKER_ID_USER/web

然后，您可以open https://cloud.docker.com/swarm/$DOCKER_ID_USER/repository/list运行以查看上传的图片。

部署图像

最后，您可以按照以下步骤在EC2上部署图像。首先，在Amazon风格的EC2实例上安装Docker和Docker-Compose：

# install docker
sudo yum install docker -y

# start docker
sudo service docker start

# allow ec2-user to run docker
sudo usermod -a -G docker ec2-user

# get the docker-compose binaries
sudo curl -L https://github.com/docker/compose/releases/download/1.20.1/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose

# change the permissions on the source
sudo chmod +x /usr/local/bin/docker-compose

退出，然后重新登录以更新用户的群组。然后启动一个屏幕并运行服务器：screen。屏幕启动后，您应该能够添加一个新的docker-compose配置文件，该文件指定已部署映像的路径。例如，我需要获取位于let-them-speak-web的Docker Cloud帐户中的yaledhlab容器，因此我将上面的docker-compose.yml文件更改为以下文件，我将其命名为{{1} }：

production.yml

然后可以使用：version: '2' services: tomcat_service: image: 'bitnami/tomcat:latest' ports: - '8080:8080' volumes: - docker-data-tomcat:/bitnami/tomcat/data/ - docker-data-blacklab:/lts-app/lts/ mongo_service: image: 'mongo' command: mongod ports: - '27017:27017' web: image: 'yaledhlab/let-them-speak-web' # gain access to linked containers links: - mongo_service - tomcat_service # explicitly declare service dependencies depends_on: - mongo_service - tomcat_service # set environment variables environment: PYTHONUNBUFFERED: 'true' ports: - '7082:7082' volumes: - docker-data-tomcat:/tomcat_webapps - docker-data-blacklab:/lts-app/lts/ volumes: docker-data-tomcat: docker-data-blacklab:运行生产撰写文件。最后，使用另一个终端ssh，并使用docker-compose -f production.yml up分隔屏幕。

Docker容器建立在OSX上但不是Amazon Linux上
