k6 extension to test and benchmark FrostFS related protocols.

---

xk6-frostfs

Build

To build a k6 binary with this extension, first ensure you have the prerequisites:

• Go
• Git

1. Install xk6 framework for extending k6:

go install go.k6.io/xk6/cmd/xk6@latest

2. Clone this repository

git clone git.frostfs.info/TrueCloudLab/xk6-frostfs
cd xk6-frostfs

3. Build the binary:

xk6 build --with git.frostfs.info/TrueCloudLab/xk6-frostfs=.

4. Run k6:

./k6 run test-script.js

API

Native

Create native client with connect method. Arguments:

• frostfs storage node endpoint
• hex encoded private key (empty value produces random key)
• dial timeout in seconds (0 for the default value)
• stream timeout in seconds (0 for the default value)

import native from 'k6/x/frostfs/native';
const frostfs_cli = native.connect("s01.frostfs.devenv:8080", "", 0, 0)

Methods

• putContainer(params). The params is a dictionary (e.g. {acl:'public-read-write',placement_policy:'REP 3',name:'container-name',name_global_scope:'false'}). Returns dictionary with success boolean flag, container_id string, and error string.
• setBufferSize(size). Sets internal buffer size for data upload and download. Default is 64 KiB.
• put(container_id, headers, payload). Returns dictionary with success boolean flag, object_id string, and error string.
• get(container_id, object_id). Returns dictionary with success boolean flag, and error string.
• onsite(container_id, payload). Returns FrostFS object instance with prepared headers. Invoke put(headers) method on this object to upload it into FrostFS. It returns dictionary with success boolean flag, object_id string and error string.

S3

Create s3 client with connect method. Arguments:

• s3 gateway endpoint

Credentials are taken from default AWS configuration files and ENVs.

import s3 from 'k6/x/frostfs/s3';
const s3_cli = s3.connect("http://s3.frostfs.devenv:8080")

You can also provide additional options:

import s3 from 'k6/x/frostfs/s3';
const s3_cli = s3.connect("http://s3.frostfs.devenv:8080", {'no_verify_ssl': 'true', 'timeout': '60s'})

• no_verify_ss - Bool. If true - skip verifying the s3 certificate chain and host name (useful if s3 uses self-signed certificates)
• timeout - Duration. Set timeout for requests (in http client). If omitted or zero - timeout is infinite.

Methods

• createBucket(bucket, params). Returns dictionary with success boolean flag and error string. The params is a dictionary (e.g. {acl:'private',lock_enabled:'true',location_constraint:'ru'})
• put(bucket, key, payload). Returns dictionary with success boolean flag and error string.
• get(bucket, key). Returns dictionary with success boolean flag and error string.
