How to get docker asset details ? (Last downloaded, Uploader)

Sonatype Nexus Repository
1

Hello,
I was trying to figure out how to get docker asset details which are normally visible via web UI, but using Nexus API…
Particularly
-Last downloaded
-Uploader
-Uploader’s IP Address
-Blob created
any ideas?
/service/rest/v1/assets/id - doesn’t show
/service/rest/v1/components/id - doesn’t show

This can be done with groovy scripting…

import org.sonatype.nexus.repository.storage.StorageFacet
import org.sonatype.nexus.repository.Repository
import org.sonatype.nexus.repository.storage.Asset

repository.repositoryManager.browse().each { Repository repo ->
    StorageFacet storageFacet = repo.facet(StorageFacet)
    def tx = storageFacet.txSupplier().get()
    try {
        tx.begin()

        tx.browseAssets(tx.findBucket(repo)).each { Asset asset ->
            log.info(asset.attributes().get('content').get('etag'))
            log.info(asset.attributes().get('content').get('last_modified'))
        }
    } finally {
        tx.close()
    }
}

The attributes available can be found in the component detail UI.

thanks Rich,
It is unpleasant that these information are not available via API directly. I am building a python script for analyzing the repo for further advanced cleanup policies (using API for advanced cleanup policy is recommended by Sonatype) and I have to split the logic to groovy script and python :frowning:

I am sorry, but the script is not working … ‘etag’ is allways null and ‘last_modified’ is required with toString() method

It’s just an example, check to see what attributes are available for the asset you are querying in the UI, and modify the script as needed.

Ok, I got, thanks … I am able to get sha256+last_modified, but I cannot find last_downloaded … I have tried to download components using groovy script, but it is also not in there… is there some doc where I can find object structure and class methods ? It is very hard to find in source code…

I have just figured it out…
There is much easier way of getting all necessary information,instead of going down through get() method - which may end in null.get() exception - use methods to access asset attributes directly… e.g.
asset.lastDownloaded()
asset.blobUpdated()
