I found a way to access older images:
- Navigate to https://uk.lxd.images.canonical.com/streams/v1/images.json
- find you image, expand
versions
key (the last 3 days are available), select the date - expand
items -> lxd.tar.xz
, copycombined_sha256
value - you can start a new container from this image like this
lxc launch images:f32c4d30aad15b2ea5a97edb2691d31d7fcaa567d8fc700f0cfef3eb4f714e00 ww
I wonder if there is a way to override existing image in cache…
