Add more versatile replication filters

[cedvan]

Hi all,

Need

I want replicate images from a namespace. But only need replicate tags "stable" to save my storage

On docker hub :

• 1.10.0-alpha
• 1.9.01
• 1.9.0
• 1.9.0-rc2
• 1.9.0-rc1
• 1.8.0

Need get on my harbor :

• 1.9.01
• 1.9.0
• 1.8.0

So ignore pre release version and alpha version to save storage.

Problem

Try configure my replication rule with existing filters (cf. https://github.com/goharbor/harbor/blob/master/docs/user_guide.md#resource-filter)

• *.*.* => but 1.9.0-rc1 match
• ?.?.? => but 1.9.01 not match
• {?.?.?,?.??.??} => Ok, but 1.10.0 soon available and so don't match

Problem : It is necessary to update the filter regularly so that my replication rule works in the future

Proposal solutions

1 - Add a pattern to match only number, like \d with regex
2 - Add more versatile replication filter like composer *, ~, ^, <, =, > (cf. https://getcomposer.org/doc/articles/versions.md#versions-and-constraints)
3 - Simply use regex as pattern to configure filter

we need a common consistent regex support for all features, not just limited to replication. Adding this to next release planning

@xaleeks was wondering if there's any tentative timeline for this work (this is still tagged for 1.11.0)? I totally agree that there need to be a consistent regex support throughout the different features, our immediate use case is with immutability rules.

as workaround we use this filter {?,??}.{?,??}.{?,??} for some kind of semver matching

@HaveFun83 This solution not match versions "X" and "X.X"

@HaveFun83 This solution not match versions "X" and "X.X"

sure "X" and "X.X" is not a semver annotation so far as i know.

Hey @xaleeks, is there any update you can provide on this? would love to this get slotted for a future version 🙏🏼

this topic has also just come up in our company, it would be fabulous if this feature were to be implimented soon.

We are waiting for this feature, too.

I have the feeling that this thread receives no attention :-(
