+### AWS CLI
+
+Information about the AWS client can be found [here](https://aws.amazon.com/cli/).
+
+!!!! **Ceph and Quobyte specific commands**
+!!!! There are some incompatibilities with some S3 commands in AWS CLI for Ceph S3 which works fine with Quobyte S3. This part will cover commands for `s3.xxx.cloud.syseleven.net` endpoints which are Quobyte and `objectstorage.fes.cloud.syseleven.net` which is our Ceph endpoint.
+!!!!
+!!!! This part will be updated regularly so it's suggested to check often.
+
+The `aws-cli` also has a configuration file which can be created under the home directory of the user which runs the command.
+
+```shell
+mdkir ~/.aws
+```
+
+The configuration for a simple use should be like this:
+
+```shell
+syseleven@kickstart:~$ cat ~/.aws/config
+[default]
+aws_access_key_id = < REPLACE ME >
+aws_secret_access_key = < REPLACE ME >
+```
+
+Listing buckets: **[Quobyte - Ceph]**
+
+```shell
+aws --endpoint-url https://s3.cbk.cloud.syseleven.net s3 ls
+```
+
+Creating a bucket:  **[Quobyte]**
+
+```shell
+aws --endpoint-url https://s3.cbk.cloud.syseleven.net s3 mb s3://test-bucket-sys11-j2j4
+```
+
+Creating a bucket:  **[Ceph]**
+
+```shell
+aws --endpoint-url https://objectstorage.fes.cloud.syseleven.net s3api create-bucket --bucket test-bucket-sys11-j2j4
+```
+
+Put a file to the bucket: **[Quobyte - Ceph]**
+
+```shell
+aws --endpoint-url https://s3.cbk.cloud.syseleven.net s3 cp test.pdf s3://test-bucket-sys11-j2j4
+```
+
+After this a simple query for the S3 bucket list can be simple as the following: **[Quobyte - Ceph]**
+
+```shell
+aws --endpoint-url https://s3.cbk.cloud.syseleven.net s3 ls s3://test-bucket-sys11-j2j4
+2022-12-14 15:14:39       3652 test.pdf
+```
+
+Objects can be removed as follows: **[Quobyte - Ceph]**
+
+```shell
+aws --endpoint-url https://s3.cbk.cloud.syseleven.net s3 rm s3://test-bucket-sys11-j2j4/test.pdf
+delete: s3://test-bucket-sys11-j2j4/test.pdf
+```

 ### Boto3
 
 Information about the `boto3` python S3 library can be found [here](https://boto3.amazonaws.com/v1/documentation/api/latest/index.html). We suggest to make use of this library to set up and manage more complex ACLs.
