Question & Answer :
I’m making an attempt to alteration repository sanction of the representation:
REPOSITORY TAG Representation ID CREATED Digital Dimension server newest d583c3ac45fd 26 minutes agone 685.5 MB
Therefore I privation to alteration the sanction server to thing similar myname/server:
REPOSITORY TAG Representation ID CREATED Digital Measurement myname/server newest d583c3ac45fd 26 minutes agone 685.5 MB
However tin I bash this?
docker representation tag server:newest myname/server:newest
oregon
docker representation tag d583c3ac45fd myname/server:newest
Tags are conscionable quality-readable aliases for the afloat representation sanction (d583c3ac45fd...).
Truthful you tin person arsenic galore of them related with the aforesaid representation arsenic you similar. If you don’t similar the aged sanction you tin distance it last you’ve retagged it:
