Instead of using AWS and JQ to get the snapshot names, you can do it with a single command using –query.
Here are the previous commands.
/usr/bin/aws lightsail get-instance-snapshots --region us-east-1 --profile default > $snaps cat $snaps | jq -r '.instanceSnapshots[] | .name' > $names |
/usr/bin/aws lightsail get-instance-snapshots --region us-east-1 --profile default > $snaps cat $snaps | jq -r '.instanceSnapshots[] | .name' > $names
Using query.
aws lightsail get-instance-snapshots \ --query 'instanceSnapshots[*].[name]' \ --region us-east-1 \ --profile default \ --output text > $names |
aws lightsail get-instance-snapshots \ --query 'instanceSnapshots[*].[name]' \ --region us-east-1 \ --profile default \ --output text > $names
When trying to boot from a disk created from snapshot and you’re getting an “UEFI feature is not available for this project” error, you’ll need to create a boot image with the –guest-os-features option set to “UEFI_COMPATIBLE.”
gcloud compute disks create new-server-disk-2 \ --project=project-name \ --source-snapshot=server-disk-2 \ --zone=us-central1-b \ --guest-os-features="UEFI_COMPATIBLE" |
gcloud compute disks create new-server-disk-2 \ --project=project-name \ --source-snapshot=server-disk-2 \ --zone=us-central1-b \ --guest-os-features="UEFI_COMPATIBLE"
It’s about enabling guest operating system features on custom images. The guest operating system features let you configure networking, security, storage, and operating system options on custom images to be used on boot disks.
Here’s how to describe snapshots using query with tags.
aws ec2 describe-snapshots \ --owner-ids xxxxxxxxxxx \ --profile default \ --region us-east-2 \ --output text \ --query "Snapshots[*].[SnapshotId,Tags[?Key=='Name'].Value[] | [0]]" |
aws ec2 describe-snapshots \ --owner-ids xxxxxxxxxxx \ --profile default \ --region us-east-2 \ --output text \ --query "Snapshots[*].[SnapshotId,Tags[?Key=='Name'].Value[] | [0]]"
Result.
snap-xxxxxxxxxxxxxxxxx Server1 snap-xxxxxxxxxxxxxxxxx Server2 |
snap-xxxxxxxxxxxxxxxxx Server1 snap-xxxxxxxxxxxxxxxxx Server2
