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
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

62a7d631-15d2-4bde-a633-b2e28b306105 Inside the console, I see that there is a section about "access points" for my S3 but it's not mentionned in the blog

did you put those asterix there?
Rozukai
Rozukai14mo ago
Yes to hide my bucket name
Brody
Brody14mo ago
are you using private networking
Rozukai
Rozukai14mo ago
Yes It's enabled by default no ?
Brody
Brody14mo ago
yes it's enabled by default, I'm not asking if you have it enabled, I'm asking if you are actually using it
Rozukai
Rozukai14mo ago
Yes I use it for some of my services

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?
Rozukai
Rozukai14mo ago
Yes for testing
Brody
Brody14mo ago

I redeploy I have the same error :/ If I use eu-west2 do you think it will work ?
Brody
Brody14mo ago
i dont think thats the issue here, look into the connection docs for the s3 client in use
Rozukai
Rozukai14mo ago
Ok i will check 😉 I think it is the bucket s3, I can't ping it
Brody
Brody14mo ago

Hi @Brody, 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 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"
],
"Effect": "Allow",
"Action": [
"s3:PutObject",
"s3:GetObject",
"s3:ListBucket"
],
You can close this issue

How did you fix the issue -- the ERR_TLS_CERT_ALTNAME_INVALID one?
