Idea #11017
Updated by Tom Morris about 7 years ago
1. provide a python program that runs arv-keepdocker, looks for pairs like the ones below, one above, and creates a tag link for each pair <pre> wardv@shell.4xphq:~$ arv-keepdocker REPOSITORY TAG IMAGE ID COLLECTION CREATED arvados/jobs c1a8e01539932e2f0153cfb2ffc4eaa2c3dc00f1 sha256:eda7c 4xphq-4zz18-5cn1x9u4ki574i7 Mon Dec 19 16:25:22 2016 arvados/jobs c1a8e01539932e2f0153cfb2ffc4eaa2c3dc00f1 decde0035258 4xphq-4zz18-sr3yairajekj11z Mon Dec 19 16:25:22 2016 </pre> 2. update API server to check for those tag links when creating a new job or container request, so when someone asks for "decde0035258" or "4xphq-4zz18-sr3yairajekj11z" or {whatever 4xphq-4zz18-sr3yairajekj11z's PDH is}, it gets transparently rewritten to sha256:eda7c or {whatever 4xphq-4zz18-5cn1x9u4ki574i7's PDH is}. Tag would look something like: <pre> owner_uuid: zzzzz-tpzed-000000000000000 link_class: docker_image_migration name: {whatever 4xphq-4zz18-sr3yairajekj11z's PDH is} head_uuid: {whatever 4xphq-4zz18-5cn1x9u4ki574i7's PDH is} </pre>
