问题
I am trying to deploy a rails app to Amazon Elastic Beanstalk(eb) environment
I got this error back:
Uploading: [##################################################] 100% Done...
2019-01-24 09:42:16 INFO Environment update is starting.
2019-01-24 09:42:26 ERROR Service:AmazonCloudFormation, Message:Template format error: Parameter 'EnvironmentVariables' default value '[****]' length is greater than 4096.
2019-01-24 09:42:26 ERROR Failed to deploy application.I found this
The combined size of all environment properties cannot exceed 4,096 bytes when stored as strings with the format key=value.
in the amazon docs here.
My environment properties key value combined is much bigger than 4096 chars.
as most of the values are credentials for API and Payments, thus I end up with just a dozen of keys.
My app work just fine in Heroku, there is no such limitation on the env variables. I am wondering what is the reason behind this restrictions in eb.
Is there anyone experience with this?
In my case, I would like to increase the limit (4096). I don't wanna change my code just to fit the eb restrictions.
I am also open for any kind of workaround to overcome this 4096 chars.
Many thanks in advance!
回答1:
Beanstalk uses Cloudformation underneath to provision environments. As a result, there is a limit on environment variables. You can not increase this limit because it is hard-coded in the kernel to PAGE_SIZE.
This is a nice resource that explains an alternative approach for solving this problem.
