部署到Elastic Beanstalk失败，出现“无法分配内存”错误
我构建了一个我想要部署到弹性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

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。 我调用了文件01setup_swap.config并将其放在项目根目录中的.ebextensions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/"
几天前我遇到过类似的问题，这就是我解决它的方法。 如果当前步骤失败，则仅进入下一步。
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
第2步：增加ElasticBeanstalk实例的大小，并尝试再次部署。
第3步：如果所有其他方法都失败了，请在rails应用中运行此命令。
bundle exec bundle package
这将编译gems并将其保存到rails应用程序中的本地文件夹（供应商/缓存）。 在部署期间访问此文件夹，并且不会进行编译。
将这些文件提交到您的repo，并尝试部署。 它应该没有障碍。
刚刚遇到这个错误。 这是我学到的以及如何通过这个问题：
使用AWS弹性beanstalk的免费层，默认情况下，截至本答复日期，您获得的EC2实例类型为t1.micro。 t1.micro的内存非常少。 这个gem的gem安装过程很少失败，因为post很明显。 t1.micro现在被认为是上一代实例类型（ https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/instance-types.html ）。 要通过此内存分配失败，您必须将AWS弹性beanstalk应用程序的EC2实例从t1.micro更新为t2.micro。 这对我有用。
