SQL Server 2022 in containers

[michvllni]

Hi,

are there plans to use SQL Server 2022 inside the containers?

Currently it is SQL 2019 and we are unable to bring databases that were on our SQL 2022 servers into the containers

[freddydk]

I have been working on this, but currently I cannot install the latest SQL 2022 hotfix in a container - it fails the installation.
I am in contact with the SQL team to see whether we can fix this.

I am creating sql server developer images for us as they are not provided by microsoft any more.

Maybe my dockerfile can help you, I'd expect express to install in a similar way as developer:

attach_dbs="[]" \
ACCEPT_EULA="_" \
bakPath="_" \

@michvllni thanks.
Have you been able to add the latest SQL Server 2022 CU to the image in the DOCKERFILE as well?
This is where I have an issue - the installation fails causing my images to run SQL 2022 RTM, which is flagged vulnerable and my images will be removed from Microsoft Security.

[michvllni]

@freddydk haven't tried yet - I'll give it a shot once I'm in the office

@freddydk
Have you achieved any progress on this topic? Many onPrem customers have upgraded to SQL 2022 and we can no longer import these databases in our development containers.

I am getting bellow error for alter login db script, any idea about this error?
