# 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`:
```shell
go install go.k6.io/xk6/cmd/xk6@latest
```
2. Clone this repository
```shell
git clone git.frostfs.info/TrueCloudLab/xk6-frostfs
cd xk6-frostfs
```
3. Build the binary:
```shell
xk6 build --with git.frostfs.info/TrueCloudLab/xk6-frostfs=.
```
4. Run k6:
```shell
./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)
```js
import native from 'k6/x/frostfs/native';
const frostfs_cli = native.connect("s01.frostfs.devenv:8080", "", 0, 0, false)
```
### 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.
## 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)
```js
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.
```js
import s3 from 'k6/x/frostfs/s3';
const s3_cli = s3.connect("https://s3.frostfs.devenv:8080")
```
You can also provide additional options:
```js
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.
```js
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](./examples) dir.
# Command line utils
To build all command line utils just run:
```shell
$ 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](./scenarios/run_scenarios.md)).
To do this use `frostfs-xk6-registry-exporter`, available flags can be seen in help:
```shell
$ ./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
```
