HOWTO部署在AWS泊坞窗的容器，而无需使用弹性的豆茎或EC2集装箱服务 [英] HOWTO deploy a docker container on aws without using elastic beanstalk or ec2 container service

问题描述

我想使用泊坞窗的容器，而无需使用弹性的豆茎或EC2集装箱服务。我想上传的.zip 文件描述容器（像你这样做有松紧豆茎），并有一个通用的EC2实例中运行它使用泊坞窗。

I'd like to use docker containers without having to use elastic beanstalk or ec2 container service. I'd like to upload a .zip file describing the container (like you do with elastic beanstalk) and have a generic ec2 instance run it using docker.

当寻找到运行的泊坞窗容器中的豆茎创建EC2实例的用户数据部分中，我看到了云计算的init脚本，下载一个大的shell脚本，做所有的设置（<一href="https://s3-eu-central-1.amazonaws.com/elasticbeanstalk-env-resources-eu-central-1/stalks/eb_docker_4.2.1/lib/UserDataScript.sh"相对=nofollow>为例）。我认为是弹性的豆茎确实也可以手动使用EC2实例和一个用户数据脚本实现的一切。

When looking into the user data section of a beanstalk-created ec2 instance running a docker container, I see a cloud-init script that downloads a big shell script that does all the setup (Example). I assume that everything that elastic beanstalk does can also be achieved manually by using ec2 instances and a user data script.

我的问题是：可能有人提供的最小的示例为用户数据脚本

My question is: Could someone provide a minimal example for a user data script that

1. 在安装/配置泊坞窗
2. 下载.zip文件
3. 在运行我的搬运工图片

我熟悉的自动缩放团体等，我想获得此安装程序，而无需使用beanstalk-或EC2集装箱业务魔术运行。

I'm familiar with auto scaling groups etc. and I'd like to get this setup running without using the beanstalk- or ec2 container service magic.

推荐答案

基本上，你需要在你的EC2实例安装泊坞窗和Nginx的（如Web代理）。然后，下载web应用程序的归档和部署。这就是弹性魔豆一样。

Basically, you need to install Docker and nginx (as web proxy) in your EC2 instance. And then, download the web-app archive and deploy it. This is what Elastic Beanstalk does.

有关基本/最低，以部署一个泊坞窗容器的Web应用程序的用户数据：

For the basic/minimal user-data in order to deploy a single docker container web application:

#!/bin/bash

IMG_LABEL=myapp
APP_INIT_URL=https://s3.amazonaws.com/your-bucket-app/myapp-init.tar.gz

function prepare_instance {
  apt-get -y update
  apt-get -y install nginx
  curl -sSL https://get.docker.com/ | sh
  mkdir /opt
  curl -o /opt/deployer.sh http://169.254.169.254/latest/user-data
  chmod 775 /opt/deployer.sh
}

function download_app {
  curl -o /tmp/current.tar.gz $1
  rm -rf /opt/app
  mkdir -p /opt/app
  tar zxvf /tmp/current.tar.gz -C /opt/app
  rm /tmp/current.tar.gz
}

function build_image {
  docker tag ${IMG_LABEL}:latest ${IMG_LABEL}:prev || echo "No built app"
  docker build -t ${IMG_LABEL}:latest /opt/app
}

function run_container {
  APP_CID=$(docker run -d ${IMG_LABEL}:latest)
  APP_IP=$(docker inspect --format '{{ .NetworkSettings.IPAddress }}' ${APP_CID})
}

function setup_proxy {
  rm /etc/nginx/sites-enabled/*
  cat <<EOT > /etc/nginx/sites-enabled/app.conf
map \$http_upgrade \$connection_upgrade {
  default upgrade;
  ''      close;
}
upstream app.local {
  server ${APP_IP};
}
server {
  listen 80;
  location / {
    proxy_pass http://app.local;
    include /etc/nginx/proxy_params;
    proxy_http_version 1.1;
    proxy_set_header Upgrade \$http_upgrade;
    proxy_set_header Connection \$connection_upgrade;
  }
}
EOT
  service nginx reload
}

function destroy_previous {
  (docker ps -a --before="${APP_CID}" | awk '{ print $1,$2 }' | grep "${IMG_LABEL}" | awk '{print $1 }' | xargs -I {} docker stop {} | xargs -I {} docker rm {}) || echo "No previous container"
  docker rmi ${IMG_LABEL}:prev || echo "No previous image"
}

if [ ! -f /opt/deployer.sh ];
then
  prepare_instance
  download_app ${APP_INIT_URL}
else
  download_app $1
fi

build_image
run_container
setup_proxy
destroy_previous

在弹性魔豆，还有就是听更新请求代理。但是，为简单起见，我们可以把上面的脚本通过SSH部署一个新的web应用程序版本：

In Elastic Beanstalk, there is an agent that listen to update request. But, to make it simple, we can call the above script to deploy a new web-app version via SSH:

ssh [e-mail] 'sudo /opt/deployer.sh https://s3.amazonaws.com/your-bucket-app/myapp-201510122341.tar.gz'

注意的：我用的EC2实例与Ubuntu 14.04

Note: I use EC2 instance with Ubuntu 14.04.
