AWS Elastic Beanstalk - Ruby 3.0 running on 64bit Amazon Linux 2/3.4.4 - Wrong PUMA version

Question

Hi all, 
I'm using** AWS Elastic Beanstalk** with** Ruby 3.0** running on 64bit Amazon Linux 2 **version 3.4.4** .

I read from documentation here https://docs.aws.amazon.com/elasticbeanstalk/latest/platforms/platform-history-ruby.html
that Puma version should be** Puma 5.6.2** but it is not true.
The actual Puma version on that machines is **5.5.2** .

Is it possible to update to the newer Puma version in the next release?

The Puma 5.5.2 one has some security issues already fixed in newest versions.

Thanks a lot

Hi and thanks for the support!
1) and 2)
I tried in new env and my env the command `ps aux | grep puma`

result in new enviroment:

```
[ec2-user@ip-172-31-9-xxx ~]$ ps aux | grep puma
healthd   1632  0.1  3.9 867356 38176 ?        Ssl  07:03   0:00 puma 5.3.2 (tcp://127.0.0.1:22221) [healthd]
webapp    1861  0.0  2.9 206692 28512 ?        Ss   07:04   0:00 puma 4.3.3 (unix:///var/run/puma/my_app.sock) [current]
webapp    1937  0.0  3.1 1158180 31188 ?       Sl   07:04   0:00 puma: cluster worker 0: 1861 [current]
webapp    1938  0.0  3.1 1158096 30420 ?       Sl   07:04   0:00 puma: cluster worker 1: 1861 [current]
ec2-user  2124  0.0  0.0 112916   476 pts/0    S+   07:13   0:00 grep --color=auto puma
```
But if I go to current app folder and run `pumactl -V` I get the correct 5.6.2 .

And in mine env was the same discussed before, 5.3.2 and 5.5.2 from `ps aux | grep puma` and 5.5.2 from `pumactl -V` .

3) yes I have 3 .ebextensions files but they should be totally safe. 1 for options (a json map key -> value), 2 this one:

```
packages:
    yum:
        amazon-linux-extras: []

commands:
    01_postgres_install:
        command: sudo amazon-linux-extras install postgresql12

```

And 3 this one to have RAM and Disk Usage monitored:

```
packages:
  yum:
    perl-DateTime: []
    perl-Sys-Syslog: []
    perl-LWP-Protocol-https: []
    perl-Switch: []
    perl-URI: []

  02-changeperm:
    command: chmod 644 /etc/cron.d/cwpump
  03-changeperm:
    command: chmod u+x /opt/cloudwatch/aws-scripts-mon/mon-put-instance-data.pl

    CloudWatchMetrics : "--mem-util --mem-used --mem-avail --disk-space-util --disk-space-used --disk-space-avail --disk-path=/ --auto-scaling"
```

4) no Procfile

Thanks again for all the support

The only diff thing that I noticed is the spot instance

so,

I created a new instance (spot) and when the creation completed, I did

`eb ssh`

and then
```
ps aux | grep puma
healthd   3600  0.2  3.7 828784 38088 ?        Ssl  14:23   0:00 puma 5.3.2 (tcp://127.0.0.1:22221) [healthd]
webapp    3830  0.1  2.8 271748 28604 ?        Ss   14:23   0:00 puma 4.3.3 (unix:///var/run/puma/my_app.sock) [current]
webapp    3910  0.0  3.0 841880 30724 ?        Sl   14:23   0:00 puma: cluster worker 0: 3830 [current]
ec2-user  4065  0.0  0.0 119420   960 pts/0    S+   14:27   0:00 grep --color=auto puma
```
and
```
pumactl -V
    5.6.2
```
As you can see the basic puma is 5.6.2 and the `healthd` puma version is again 5.3.2...

1) Can you please create you too also a new spot instance environment, as I do, and run with `eb ssh` the same commands:
```
ps aux | grep puma
pumactl -V
```
2) Can you please run in your original env `ps aux | grep puma`?

3) Do you have any `.ebextensions` in your original env? Can you share them with us?

4) Is there any `Procfile` on your root app?

Dear @emish89
Hello,

I am trying also to use the AWS EB Ruby 3.0 running on 64bit Amazon Linux 2/3.4.4 but until now I did not manage to make it work

In env status I get: 
```
100.0 % of the requests are failing with HTTP 5xx
```
also in /var/log/nginx/error.log
```
[error] 2459#2459: *596 connect() to unix:///var/run/puma/my_app.sock failed (11: Resource temporarily unavailable) while connecting to upstream, client: 172.31.34.113, server: _, request: "POST / HTTP/1.1", upstream: "http://unix:///var/run/puma/my_app.sock:/", host: "52.29.66.93"
```
and in /var/log/puma/puma.log
```
[4898] ! Unable to start worker

[4898] Early termination of worker
```
As for your question, in my instance the version is 5.6.2, as expected
```
[ec2-user@ip-172-31-xx-xx ~]$ pumactl -V
5.6.2
```
How did you see the the version is 5.5.2?

If I check the processes:
```
ps aux | grep puma
    healthd  25925  0.0  3.6 828800 36624 ?        Ssl  09:39   0:15 puma 5.3.2 (tcp://127.0.0.1:22221) [healthd]
    webapp   26497  0.2  2.2 255768 22912 ?        Ss   09:40   1:07 puma 5.6.2 (unix:///var/run/puma/my_app.sock) [current]
    webapp   28653 64.0  2.1 327180 21668 ?        Rl   16:08   0:00 puma: cluster worker 0: 26497 [current]
    ec2-user 28656  0.0  0.0 119420   924 pts/0    S+   16:08   0:00 grep --color=auto puma
```
I see another puma v5.3.2
Maybe this other puma version is used for another reason (health service)?
