Upload the object: swift -A http://<rgw -host>:8080/auth/v1.0 -U swiftuser:swift -K <password> upload my -container /path/to/file Explanation: Swift commands provide compatibility for uploading objects in OpenStack -compatible environments. Download an object from a RADOS gateway using Swift commands. ee the solution below. Solution: 1. Authenticate with the Swift endpoint: swift -A http://<rgw -host>:8080/auth/v1.0 -U swiftuser:swift -K <password> list 2. Download the object: swift -A http://<rgw -host>:8080/auth/v1.0 -U swiftuser:swift -K <password> download my -container file Explanation: Downloading objects with Swift commands ensures seamless integration with OpenStack and other compatible systems.
Configure RADOS gateway logging and verify the logs for S3 API usage. ee the solution below. Solution: 1. Enable S3 logging in the configuration file: rgw_log_http_headers = true rgw_log_object_name = true 2. Restart the RADOS gateway: systemctl restart ceph -radosgw@rgw.<hostname> 3. Verify the logs: tail -f /var/log/ceph/ceph -client.rgw.<hostname>.log Explanation: Enabling and analyzing S3 API logs help monitor usage and troubleshoot issues. Configure and test bucket versioning in RADOS gateway for S3 -compatible object storage. ee the solution below. Solution: 1. Enable bucket versioning using the S3 API: aws s3api put -bucket -versioning --bucket bucket -name --versioning -configuration Status=Enabled 2. Verify versioning status: aws s3api get -bucket -versioning --bucket bucket -name Explanation: Bucket versioning allows tracking changes and recovering previous versions of objects, enhancing data protection. Implement and test bucket lifecycle policies for S3 -compatible object storage.
ee the solution below. Solution: 1. Create a lifecycle policy in JSON format: { "Rules": [ { "ID": "DeleteOldObjects", "Status": "Enabled", "Expiration": { "Days": 30 } } ] } 2. Apply the lifecycle policy: aws s3api put-bucket -lifecycle -configuration --bucket bucket -name --lifecycle -configuration file://policy.json Explanation: Lifecycle policies automate object management by applying rules for retention, archiving, or deletion. Enable SSL encryption for the RADOS gateway and verify secure access. ee the solution below. Solution: 1. Generate an SSL certificate: openssl req -newkey rsa:2048 -nodes -keyout rgw.key -x509 -days 365 -out rgw.crt 2. Update the RADOS gateway configuration: rgw_frontends = beast ssl_port=443 ssl_certificate=/path/to/rgw.crt 3. Restart the RADOS gateway: systemctl restart ceph -radosgw@rgw.<hostname> Explanation:
Enabling SSL secures communications to the RADOS gateway, ensuring data integrity and confidentiality. Create a new S3 bucket in a specific zone and verify its location. ee the solution below. Solution: 1. Create the bucket in a specific zone: aws s3api create -bucket --bucket bucket -name --create -bucket -configuration LocationConstraint=zone - name 2. Verify the bucket’s zone: aws s3api get -bucket -location --bucket bucket -name Explanation: Bucket creation in specific zones ensures optimized data placement and compliance with regional requirements. Enable server -side encryption for a bucket in RADOS Gateway and upload an encrypted object. ee the solution below. Solution: 1. Enable bucket encryption: aws s3api put-bucket -encryption --bucket bucket -name --server -side-encryption -configuration '{"Rules":[{"ApplyServerSideEncryptionByDefault":{"SSEAlgorithm":"AES256"}}]}' 2. Verify bucket encryption: aws s3api get -bucket -encryption --bucket bucket -name 3. Upload an encrypted object: aws s3 cp /path/to/file s3://bucket -name/ Explanation:
Server -side encryption secures data at rest within the RADOS Gateway, meeting compliance and security standards. Configure multipart upload for large objects using the S3 API and verify its success. ee the solution below. Solution: 1. Initiate a multipart upload: aws s3api create -multipart -upload --bucket bucket -name --key large -object 2. Upload parts: aws s3api upload -part --bucket bucket -name --key large -object --part-number 1 --body part1 --upload -id <upload -id> aws s3api upload -part --bucket bucket -name --key large -object --part-number 2 --body part2 --upload -id <upload -id> 3. Complete the upload: aws s3api complete -multipart -upload --bucket bucket -name --key large -object --multipart -upload file://parts.json --upload -id <upload -id> Explanation: Multipart uploads optimize performance for large objects by splitting data into smaller parts, ensuring reliability. Configure RADOS Gateway quotas for buckets and users and verify their enforcement. ee the solution below. Solution: 1. Set a bucket quota: radosgw -admin quota set --bucket=bucket -name --max-size=10G 2. Set a user quota: radosgw -admin quota set --uid=s3user --max-size=50G
3. Apply the new CRUSH map: crushtool -c crush.txt -o crush.map ceph osd setcrushmap -i crush.map Explanation: CRUSH maps define how data is distributed across OSDs. Customizing these maps allows fine-grained control over data placement. Set up Ceph storage with authentication enabled and verify that clients require keys to access the cluster. ee the solution below. Solution: 1. Enable authentication in the Ceph configuration file: ceph config set mon auth_allow_insecure_global_id_reclaim false 2. Generate a client key: ceph auth get -or-create client.admin 3. Verify client access using the key: ceph -s --keyring /etc/ceph/ceph.client.admin.keyring Explanation: Enabling authentication adds a layer of security, ensuring only authorized clients can interact with the cluster. Deploy Ceph storage and configure BlueStore as the OSD backend for optimal performance. ee the solution below. Solution: 1. Update the playbook with BlueStore settings: osd_objectstore: bluestore
