Clean up snapshots older than 1 year

[vijay-veeranki]

Background

To reduce cost and improve security on the platform we need to delete old EBS snapshots.

Proposed user journey

Run this script in the concourse pipeline scheduling it every day.

year_older=$( date -v  -1y +"%Y-%m-%d" )

----- Delete older than 1 year for all snapshots
for K in $(aws ec2 describe-snapshots \
    --owner-ids 754256621582  \
    --region=eu-west-2  \
    --query "Snapshots[?(StartTime <'${year_older}')].[SnapshotId]" --output text); do
echo "deleting ${K}"
aws ec2 --region eu-west-2 delete-snapshot --snapshot-id $K
echo "Successfully deleted snapshot ${K}"
done
-----
----- Delete older than 3 months for velero snapshots
for K in $(aws ec2 describe-snapshots \
    --owner-ids 754256621582  \
    --region=eu-west-2  \
    --filters "Name=tag:velero.io/schedule-name,Values=velero-allnamespacebackup" \
    --query "Snapshots[?(StartTime <'${year_older}')].[SnapshotId]" --output text); do
echo "deleting ${K}"
aws ec2 --region eu-west-2 delete-snapshot --snapshot-id $K
echo "Successfully deleted snapshot ${K}"
done
