Cloudflare R2 のバケツ容量を取る。AWS CLI で。

R2 のバケツ量をとる

AWS CLI を使う。

1. credential を作る

~/AWS $ aws configure --profile cfr2
aws configure
AWS Access Key ID [None]: <R2のやつ>
AWS Secret Access Key [None]: <R2のやつ>
Default region name [None]: auto
Default output format [None]: json
~/AWS $ cat ~/.aws/credentials
[cfr2]
aws_access_key_id = <R2のやつ>
aws_secret_access_key = <R2のやつ>

2. AWS用の script を編集する

#!/bin/bash
set +x
PROFILE="< ↑cred のプロファイル名 >"
ACCOUNTID="< Cloudflare のアカウント ID >"
R2END="https://${ACCOUNTID}.r2.cloudflarestorage.com"
function calcs3bucketsize() {
    sizeInBytes=`aws --profile ${PROFILE} s3 ls s3://"${1}" --recursive --human-readable --summarize --endpoint-url ${R2END} | awk END'{print}'`
    echo ${1},${sizeInBytes} >> allregions-buckets-s3-sizes.csv
    printf "DONE. Size of the bucket ${1}. %s\n " "${sizeInBytes}"
}
[ -f allregions-buckets-s3-sizes.csv ] && rm -fr allregions-buckets-s3-sizes.csv
buckets=`aws --profile ${PROFILE}  s3 ls --endpoint-url ${R2END} | awk '{print $3}'`
i=1
for j in ${buckets}; do
    printf "calculating the size of the bucket[%s]=%s. \n " "${i}" "${j}"
    i=$((i+1))
    # to expedite the calculation, make the cli commands run parallel in the background
    calcs3bucketsize ${j} &
done

3. 結果

容量によって時間かかる

~/AWS $ ./r2.bucket.size.sh
calculating the size of the bucket[1]=logpush.
 calculating the size of the bucket[2]=logpush-workers.
 %
~/AWS $  DONE. Size of the bucket logpush-workers.    Total Size: 58.7 KiB
 DONE. Size of the bucket logpush.    Total Size: 789.2 MiB
