部署到Elastic Beanstalk失败,出现"无法分配内存"错误

Question

我构建了一个我想部署到弹性beanstalk的rails应用程序.我能够将其部署到我的AWS账户,但现在我想将其部署到我的客户账户.出于某种原因,我在尝试部署它时遇到错误.能够从头开始将它部署到我的帐户并能够将其部署到heroku,但每次我尝试将其部署到我的客户帐户时,我都会遇到一堆错误.这两个帐户之间是否存在可能的设置？我不明白为什么部署到这两个帐户会有所不同.我尝试了所有可以找到的解决方案.

这是日志.我不确定他们是否会有所帮助

Answer 1

我发现基于博客文章的 @osazemeu的答案需要调整,因为container_commands执行太晚(在应用程序已经设置之后),因此它从未运行过.

我将container_command更改为命令(请参阅此AWS文档以获取有关两者之间差异的详细信息),并且还创建了内联文件而不是单独的.sh文件,因为我不想跟踪哪个目录是在部署时被放入.我调用了该文件01setup_swap.config并将其放在.ebextensions项目根目录中.这对我有用.内容如下:

files:
  "/home/ec2-user/setup_swap.sh":
    mode: "000755"
    owner: root
    group: root
    content: |
      #!/bin/bash
      # based on http://steinn.org/post/elasticbeanstalk-swap/

      SWAPFILE=/var/swapfile
      SWAP_MEGABYTES=2048

      if [ -f $SWAPFILE ]; then
        echo "Swapfile $SWAPFILE found, assuming already setup"
        exit;
      fi

      /bin/dd if=/dev/zero of=$SWAPFILE bs=1M count=$SWAP_MEGABYTES
      /bin/chmod 600 $SWAPFILE
      /sbin/mkswap $SWAPFILE
      /sbin/swapon $SWAPFILE

commands:
  01setup_swap:
    command: "bash setup_swap.sh"
    cwd: "/home/ec2-user/"

Answer 2

几天前我遇到了类似的问题，这就是我解决的方法。仅当当前步骤失败时才继续执行下一步。

步骤 1：增加 ElasticBean EC2 实例的交换内存

yourapp/.ebextensions/setup_swap.sh
#!/bin/bash

SWAPFILE=/var/swapfile
SWAP_MEGABYTES=2048

if [ -f $SWAPFILE ]; then
        echo "Swapfile $SWAPFILE found, assuming already setup"
        exit;

/bin/dd if=/dev/zero of=$SWAPFILE bs=1M count=$SWAP_MEGABYTES
/bin/chmod 600 $SWAPFILE
/sbin/mkswap $SWAPFILE
/sbin/swapon $SWAPFILE

步骤 1.1 在 yourapp/.ebextensions/01_setup_swap.config 中

container_commands:
    01setup_swap:
        command: "bash .ebextensions/swap/setup_swap.sh"

来源：elasticbeanstalk-swap

步骤 2：增加 ElasticBeanstalk 实例的大小，然后尝试再次部署。

步骤 3：如果其他方法均失败，请在 Rails 应用程序中运行此命令。

bundle exec bundle package

这会编译 gem 并将其保存到 Rails 应用程序中的本地文件夹（供应商/缓存）中。该文件夹是部署时访问的，编译时不会有。

将这些文件提交到您的存储库，并尝试部署。它应该可以顺利工作。
