document (prominently) required tag for r-apt? #392

Open greg-minshall opened 4 years ago

hi. thanks very much for this! i'm new to docker, and had trouble getting rocker/r-apt (see below). eventually i realized the tag should be the specific Debian "name" (artful, etc.). maybe it would be worth putting a note next to, e.g., r-apt, telling people this? (for a while, i assumed r-apt had been abandoned).

again, thanks.

bash (master): {1008} sudo docker run --rm -ti rocker/r-apt
Unable to find image 'rocker/r-apt:latest' locally
docker: Error response from daemon: manifest for rocker/r-apt:latest not found: manifest unknown: manifest unknown.
See 'docker run --help'.

I have some difficulties with that paragraph. Are you saying that you are disappointed that no release is tagged latest? Well, they are distro specific... Also 'artful', 'bionic', ... are Ubuntu names, not Debian names. These are Ubuntu builds.

Dirk, for me, as an uninitiated docker guy, flailing around trying this, trying that (hmm, there's a song in there), the idea occured that "there should be a :latest tag" (since that what docker seems to assume, when you don't specify a tag). so, really, i understand why the labeling -- i just might suggest a note telling people that r-apt (and any others that don't have :latest) are tagged by Ubuntu release. cheers.
