The Docker V2 API requires an OAuth bearer token with the appropriate claims  In my opinion  the official documentation is rather vague on the topic  So that others don t go through the same pain I did  I offer the below docker-tags function   The most recent version of docker-tags can be found in my GitHubGist    List Docker Image Tags using bash     The docker-tags function has a dependency on jq   If you re playing with JSON  you likely already have it      usr bin env bash docker-tags         arr             for item in    arr           do         tokenUri  https   auth docker io token          data   service registry docker io   scope repository  item pull           token    curl --silent --get --data-urlencode   data 0   --data-urlencode   data 1    tokenUri   jq --raw-output   token            listUri  https   registry-1 docker io v2  item tags list          authz  Authorization  Bearer  token          result    curl --silent --get -H  Accept  application json  -H  Authorization  Bearer  token   listUri   jq --raw-output               echo  result     done     Example  docker-tags  microsoft nanoserver   microsoft dotnet   library mongo   library redis    Admittedly  docker-tags makes several assumptions  Specifically  the OAuth request parameters are mostly hard coded  A more ambitious implementation would make an unauthenticated request to the registry and derive the OAuth parameters from the unauthenticated response
