au lancement du service le disque dur tourne comme un fou et presque tout le cpu est mangé, ca peut-être "extrêmement" long...
c'est normal
, cette nouvelle version utilise un nouveau format, il doit donc transformer toutes les images existantes.donc ne pas attendre le reboot et le relancer avant !
docker v1.10-migrator
A migration is performed the first time docker is run, and can take a significant amount of time depending on the number of images present.
To make your current images accessible to the new model we have to migrate them to content addressable storage. This means calculating the secure checksums for your current data.
All your current images, tags and containers are automatically migrated to the new foundation the first time you start Docker Engine 1.10. Before loading your container, the daemon will calculate all needed checksums for your current data, and after it has completed, all your images and tags will have brand new secure IDs.
While this is simple operation, calculating SHA256 checksums for your files can take time if you have lots of image data. On average you should assume that migrator can process data at a speed of 100MB/s. During this time your Docker daemon won’t be ready to respond to requests.
