Hi everyone, I've just deploy the template to automate postgresql backups and I got this error when the script try to deploy the backup :

Error while running backup:  Error: getaddrinfo EAI_AGAIN ******.s3.us-west-3.amazonaws.com

Do you know why I got this error ?

Have a good day

Inside the console, I see that there is a section about "access points" for my S3 but it's not mentionned in the blog

devout linden did you put those asterix there?

Yes to hide my bucket name

#

are you using private networking

tidal shale Sep 27, 2023, 3:53 PM

#

devout linden are you using private networking

Yes

#

It's enabled by default no ?

devout linden Sep 27, 2023, 3:54 PM

#

yes it's enabled by default, I'm not asking if you have it enabled, I'm asking if you are actually using it

tidal shale Sep 27, 2023, 3:58 PM

#

Yes I use it for some of my services

devout linden Sep 27, 2023, 3:58 PM

I've forked the original one

#

To add a feature

#

Basically to backup more than one database

#

It's the same logic from the original one but with a foreach loop

#

do you have it set to run a backup at start?

tidal shale Sep 27, 2023, 4:00 PM

#

Yes for testing

devout linden Sep 27, 2023, 4:01 PM

#

can you prefix the start script with sleep 3 &&

tidal shale Sep 27, 2023, 4:06 PM

#

I redeploy

tidal shale Sep 27, 2023, 4:21 PM

#

I have the same error :/

#

If I use eu-west2 do you think it will work ?

devout linden Sep 27, 2023, 4:23 PM

#

i dont think thats the issue here, look into the connection docs for the s3 client in use

tidal shale Sep 27, 2023, 4:23 PM

#

Ok i will check 😉

tidal shale Sep 27, 2023, 5:56 PM

#

I think it is the bucket s3, I can't ping it

devout linden Sep 27, 2023, 5:56 PM

#

well thats odd

Hi @devout linden,

Sorry it take some times to work on my project.

I've try on the eu-west-2 region and get the following error :

Error while running backup:  PermanentRedirect: The bucket you are attempting to access must be addressed using the specified endpoint. Please send all future requests to this endpoint.

}

So locally, on my WSL, I've try to debug the project, by setting the AWS_S3_ENDPOINT=https://***.s3.eu-west-2.amazonaws.com provided by the project, I now got this error :

#

Error while running backup:  Error [ERR_TLS_CERT_ALTNAME_INVALID]: Hostname/IP does not match certificate's altnames: Host: ***.ezexchange-db-backups.s3.eu-west-2.amazonaws.com. is not in the cert's altnames: DNS:*.s3.eu-west-2.amazonaws.com, DNS:s3.eu-west-2.amazonaws.com, DNS:*.s3-eu-west-2.amazonaws.com, DNS:s3-eu-west-2.amazonaws.com, DNS:*.s3.dualstack.eu-west-2.amazonaws.com, DNS:s3.dualstack.eu-west-2.amazonaws.com, DNS:*.s3.amazonaws.com, DNS:*.s3-control.eu-west-2.amazonaws.com, DNS:s3-control.eu-west-2.amazonaws.com, DNS:*.s3-control.dualstack.eu-west-2.amazonaws.com, DNS:s3-control.dualstack.eu-west-2.amazonaws.com, DNS:*.s3-accesspoint.eu-west-2.amazonaws.com, DNS:*.s3-accesspoint.dualstack.eu-west-2.amazonaws.com, DNS:*.s3-deprecated.eu-west-2.amazonaws.com, DNS:s3-deprecated.eu-west-2.amazonaws.com

#

Do you have those kind of errors ?

#

I've put *** to hide my bucket name

tidal shale Oct 3, 2023, 6:28 PM

#

I've fix the issue but another is triggered :
Error while running backup: AccessDenied: Access Denied

The policy in the blog post is too restrictif. You must put those allowed actions :

"Effect": "Allow",
"Action": [
    "s3:PutObject",
    "s3:GetObject",
    "s3:ListBucket"
],
