Public AMIs & EBS Snapshots

AWS inaruhusu kutoa ufikiaji kwa mtu yeyote kupakua AMIs na Snapshots. Unaweza kuorodhesha rasilimali hizi kwa urahisi kutoka kwa akaunti yako mwenyewe:

# Public AMIs
aws ec2 describe-images --executable-users all

## Search AMI by ownerID
aws ec2 describe-images --executable-users all --query 'Images[?contains(ImageLocation, `967541184254/`) == `true`]'

## Search AMI by substr ("shared" in the example)
aws ec2 describe-images --executable-users all --query 'Images[?contains(ImageLocation, `shared`) == `true`]'

# Public EBS snapshots (hard-drive copies)
aws ec2 describe-snapshots --restorable-by-user-ids all
aws ec2 describe-snapshots --restorable-by-user-ids all | jq '.Snapshots[] | select(.OwnerId == "099720109477")'

Ikiwa unapata snapshot ambayo inaweza kurejeshwa na mtu yeyote, hakikisha kuangalia AWS - EBS Snapshot Dump kwa maelekezo ya kupakua na kuiba snapshot hiyo.
