The `ctr image usage` can display the usage of snapshots with a given image ref. It's easy for user to get chain snapshot IDs and unpack usage. And according to the [discuss][1], this subcommand can be used to ensure if snapshot's pagecache has been discarded in a unexpected reboot. How to use it: ```bash $ bin/ctr image usage --snapshotter native docker.io/library/golang:1.19.3 ctr: image docker.io/library/golang:1.19.3 isn't unpacked in snapshotter native $ bin/ctr image usage --snapshotter overlayfs docker.io/library/golang:1.19.3 KEY SIZE INODES sha256:28114d8403bac6352c3e09cb23e37208138a0cd9d309edf3df38e57be8075a1d 16.0 KiB 4 sha256:f162c02ce6b9b594757cd76eda1c1dd119b88e69e882cb645bf7ad528b54f0d2 476.2 MiB 13660 sha256:a5b9faceaa495819b9ba7011b7276c4ffaffe6c7b9de0889e11abc1113f7b5ca 225.5 MiB 3683 sha256:412b2615d27d6b0090558d25b201b60a7dff2a40892a7e7ca868b80bf5e5de41 159.8 MiB 6196 sha256:dbce1593502d39c344ce089f98187999f294de5182a7106dcb6c9d04ce0c7265 19.4 MiB 502 sha256:8953bf5d24149e9b2236abc76bd0aa14b73828f1b63e816cb4b457249f6125bc 12.2 MiB 958 sha256:ccba29d6937047c719a6c048a7038d3907590fbb8556418d119469b2ad4f95bc 134.7 MiB 7245 $ bin/ctr image usage --snapshotter overlayfs docker.io/library/golang:1.19 ctr: failed to ensure if image docker.io/library/golang:1.19 exists: image "docker.io/library/golang:1.19": not found ``` [1]: <containerd#5854 (comment)> Signed-off-by: Wei Fu <[email protected]>
