Delete multiple file systems on AWS EFS

README.md

Required packages

• jq
• pv
• docker or AWS CLI

If you have the AWS CLI already installed, change aws_fetch to

aws_fetch () {
    aws efs describe-file-systems --query 'FileSystems[*].FileSystemId' --no-paginate \
        --no-cli-pager | jq . > file-system.json
}

and aws_delete to

aws_delete () {
    aws efs delete-file-system --no-cli-pager --file-system-id $1
}

AWS_DEFAULT_OUTPUT is set to json and AWS_PAGER is set to "".

aws-delete-file-systems.sh

#!/bin/bash
USER=$(whoami)

aws_delete () {
    docker run --rm -i -e AWS_ACCESS_KEY_ID \
        -e AWS_SECRET_ACCESS_KEY -e AWS_DEFAULT_REGION \
        -e AWS_DEFAULT_OUTPUT -e AWS_PAGER \
        -v /home/${USER}/.aws:/root/.aws:z amazon/aws-cli:2.6.1 \
        efs delete-file-system --no-cli-pager --file-system-id $1
}

aws_fetch () {
    docker run --rm -i -e AWS_ACCESS_KEY_ID \
        -e AWS_SECRET_ACCESS_KEY -e AWS_DEFAULT_REGION \
        -e AWS_DEFAULT_OUTPUT -e AWS_PAGER \
        -v /home/${USER}/.aws:/root/.aws:z amazon/aws-cli:2.6.1 \
        efs describe-file-systems --query 'FileSystems[*].FileSystemId' --no-paginate \
            --no-cli-pager | jq . > file-system.json
}

if [ ! -f file-system.json ]
    then
        echo "Fetching the file systems to be removed"
        aws_fetch

total=$(jq ". | length" file-system.json)
echo "There are $total file systems to be removed"

    then
        readarray -t fs_array < <(jq -c -r ".[]" file-system.json)

        for fsid in "${fs_array[@]}"; do
            aws_delete $fsid
        done | pv -p -s $total --line-mode --eta --timer > /dev/null
