Deployment to Elastic Beanstalk fails with 'Ca

Question

I built a rails application that I want to deploy to elastic beanstalk. I was able to deploy it to my AWS account but now I want to deploy it to my clients account. For some reason it I get errors when trying to deploy it. Have been able to deploy it to my account from scratch and been able to deploy it to heroku but every time I try to deploy it to my clients account I get a bunch of errors. Are there possible settings that would be different between the two accounts? I don't understand why deploying to the two accounts would be any different. I have tried every solution I could find.

Here are the logs. I am not sure if they will help

  gem 'autoprefixer-rails'
  gem 'puma'

    gem "letter_opener"

  end

  Don't run Bundler as root. Bundler can ask for sudo if it is needed, and
  installing your bundle as root will break this application for all non-root

Answer 1

I found that the answer from @osazemeu based on the blog article needed a tweak, because the container_commands execute too late (after the application was already set up), and thus it was never run.

I changed the container_command into a command (see this AWS documentation for detail on the difference between the two), and also created the file inline rather than having a separate .sh file since I didnt want to have to keep track of what directory that was being put in at deployment time. I called the file 01setup_swap.config and placed in the directory .ebextensions in the root of my project. This did the trick for me. The contents is as follows:

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

I encountered similar issues a couple of days back and this was how I solved it. Only proceed to the next step if the present step fails.

Step 1: Increase the swap memory of your ElasticBean EC2 instance

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

Step 1.1 In your yourapp/.ebextensions/01_setup_swap.config

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

source: elasticbeanstalk-swap

Step 2: Increase the size of your ElasticBeanstalk instance, and try to deploy again.

Step 3: If all else fails, run this command in your rails app.

bundle exec bundle package

This compiles the gems and saves it to a local folder (vendor/cache) in your rails app. This folder is accessed during deployment, and there will be no for compilation.

Commit these files to your repo, and attempt to deploy. It should work without hitches.

Answer 3

Just ran in to this error. Here is what I learned and how I got passed this issue:

With the free tier of AWS elastic beanstalk, by default the EC2 instance type you get, as of the date of this answer, is t1.micro. t1.micro has a very small amount of memory. So little that the gem install process for this gem fails as it is evident by the post. t1.micro is now considered a previous generation instance type (https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/instance-types.html). To get past this memory allocation failure, you must update the EC2 instance of your AWS elastic beanstalk app from t1.micro to t2.micro. This worked for me.
