EFS Mount Targets not created when ebextension runs...

[ricardo-mela]

Hi,

I have noticed that it may happen that your environment is running the ebextensions when the mount targets are not yet created. As such, the update operation fails since the mount-efs.sh script exits due to the mount points not being ready.

I added a sleep 120 in the script to take me out of the immediate issue and it solves it, but it would be good to have some kind of retry logic for that command.

I'm running into the same issue, I see:

mount.nfs4: Failed to resolve server fs-....efs.....amazonaws.com: Name or service not known
ERROR: Mount command failed!.

@ricardo-mela where in the script did you add this? Can you provide a snippet of the code where you added it? Thanks!

Line 60 of https://github.com/aws-samples/eb-php-wordpress/blob/master/.ebextensions/efs-mount.config is a good place to do so.

Otherwise, you can run a loop with an aws efs describe-mount-targets --file-system-id ${EFS_FILE_SYSTEM_ID} command and continue when the command returns exit code 0. Try not use exponential backoff or similar, as in any AWS API call.

As mentioned on my previous comment,

I have exactly the same problem here.
Using a sleep command, as ricardo-mela suggested, did not work for me.

Finally, to get wordpress running, I've had to disable the EFS creation.

A good solution without disabling the EFS creation would be appreciated.

Could you use the built-in wait? https://docs.aws.amazon.com/cli/latest/reference/ec2/wait/volume-available.html

Finally I've found the problem, but not the solution (well, perhaps a possible solution is not using Amazon Linux 2). It is described here:

[dherrerab]

Yes, I can definitely confirm that using Amazon Linux 1 instead of 2 everything works correctly.

Hi @dherrerab
How to disable the EFS creation?

Well, it's been a long time since this, I can hardly remember, but I suppose that just not including the files efs-create.config and efs-mount.config in the folder .ebextensions should do the trick.
