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)
• generate object header on the client side (for big object - split locally too)
• max size for generated object header on the client side (for big object - the size that the object is splitted into)

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

Methods

• putContainer(params). The params is a dictionary (e.g. {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.

Local

Create a local client with connect method. Arguments:

• local path to frostfs storage node configuration file
• local path to frostfs storage node configuration directory
• hex encoded private key (empty value produces random key)
• whether to use the debug logger (warning: very verbose)

import local from 'k6/x/frostfs/local';
const local_client = local.connect("/path/to/config.yaml", "/path/to/config/dir", "", false)

Methods

• 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.
• delete(container_id, object_id). Returns dictionary with success boolean flag, 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("https://s3.frostfs.devenv:8080")

You can also provide additional options:

import s3 from 'k6/x/frostfs/s3';
const s3_cli = s3.connect("https://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.

S3 Local

Create local s3 client with connect method. Arguments:

• local path to frostfs storage node configuration file
• local path to frostfs storage node configuration directory
• parameter map with the following options:
  • hex_key: private key to use as a hexadecimal string. A random one is created if none is provided.
  • node_position: position of this node in the node array if loading multiple nodes independently (default: 0).
  • node_count: number of nodes in the node array if loading multiple nodes independently (default: 1).
  • debug_logger: whether to use the development logger instead of the default. Helpful for debugging (default: false).
• bucket-container mapping, which is needed to resolve the container id for a given bucket name. Any bucket used by the client must have an entry here.

import local from 'k6/x/frostfs/local';
const params = {'node_position': 1, 'node_count': 3}
const bucketMapping = {'mytestbucket': 'GBQDDUM1hdodXmiRHV57EUkFWJzuntsG8BG15wFSwam6'}
const local_client = local.connect("/path/to/config.yaml", "/path/to/config/dir", params, bucketMapping)

Methods

• 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.

Examples

See native protocol and s3 test suite examples in examples dir.

Command line utils

To build all command line utils just run:

$ make

All binaries will be in bin directory.

Export registry db

You can export registry bolt db to json file, that can be used as pregen for scenarios (see docs). To do this use frostfs-xk6-registry-exporter, available flags can be seen in help:

$ ./bin/frostfs-xk6-registry-exporter -h
Registry exporter for xk6

Usage:
registry-exporter [flags]

Examples:
registry-exporter registry.bolt
registry-exporter --status created --out out.json registry.bolt

Flags:
--age int         Object age
--format string   Output format (default "json")
-h, --help            help for registry-exporter
--out string      Path to output file (default "dumped-registry.json")
--status string   Object status (default "created")
-v, --version         version for registry-exporter

Import pregen into registry db

You can import pregenerated json files into registry bolt db. Use frostfs-xk6-registry import. Usage examples are in help:

$ ./bin/frostfs-xk6-registry import -h
Import objects into registry from pregenerated files

Usage:
  xk6-registry import [flags]

Examples:
xk6-registry import registry.bolt preset.json
xk6-registry import registry.bolt preset.json another_preset.json

Flags:
  -h, --help   help for import
