## Installation
### Using Docker (Recommended)
Pull the latest Dodo image from Docker Hub:
```sh
docker pull aykhans/dodo:latest
```
To use Dodo with Docker and a local config file, mount the config file as a volume and pass it as an argument:
```sh
docker run -v /path/to/config.json:/config.json aykhans/dodo -f /config.json
```
If you're using a remote config file via URL, you don't need to mount a volume:
```sh
docker run aykhans/dodo -f https://raw.githubusercontent.com/aykhans/dodo/main/config.yaml
```
### Using Pre-built Binaries
Download the latest binaries from the [releases](https://github.com/aykhans/dodo/releases) section.
### Building from Source
To build Dodo from source, ensure you have [Go 1.24+](https://golang.org/dl/) installed.
```sh
go install -ldflags "-s -w" github.com/aykhans/dodo@latest
```
## Usage
Dodo supports CLI arguments, configuration files (JSON/YAML), or a combination of both. If both are used, CLI arguments take precedence.
### 1. CLI Usage
Send 1000 GET requests to https://example.com with 10 parallel dodos (threads), each with a timeout of 2 seconds, within a maximum duration of 1 minute:
```sh
dodo -u https://example.com -m GET -d 10 -r 1000 -o 1m -t 2s
```
With Docker:
```sh
docker run --rm -i aykhans/dodo -u https://example.com -m GET -d 10 -r 1000 -o 1m -t 2s
```
### 2. Config File Usage
Send 1000 GET requests to https://example.com with 10 parallel dodos (threads), each with a timeout of 800 milliseconds, within a maximum duration of 250 seconds:

}
```
```sh

#### 2.2 YAML/YML Example
```yaml
method: "GET"

dodos: 10
requests: 1000
duration: "10s"
params:
# A random value will be selected from the list for first "key1" param on each request
# And always "value" for second "key1" param on each request
# e.g. "?key1=value2&key1=value"
- key1: ["value1", "value2", "value3", "value4"]
- key1: "value"
# A random value will be selected from the list for param "key2" on each request
# e.g. "?key2=value2"
- key2: ["value1", "value2"]
headers:
# A random value will be selected from the list for first "key1" header on each request
# And always "value" for second "key1" header on each request
# e.g. "key1: value3", "key1: value"
- key1: ["value1", "value2", "value3", "value4"]
- key1: "value"
# A random value will be selected from the list for header "key2" on each request
# e.g. "key2: value2"

cookies:
# A random value will be selected from the list for first "key1" cookie on each request

# e.g. "key2=value1"
- key2: ["value1", "value2"]
body: "body-text"
# OR
# A random body value will be selected from the list for each request

- "body-text1"
- "body-text2"
- "body-text3"

```
```sh
dodo -f /path/config.yaml
# OR
dodo -f https://example.com/config.yaml
```
With Docker:
```sh
docker run --rm -i -v /path/to/config.yaml:/config.yaml aykhans/dodo -f /config.yaml
# OR

```
### 3. CLI & Config File Combination
CLI arguments override config file values:
```sh
dodo -f /path/to/config.yaml -u https://example.com -m GET -d 10 -r 1000 -o 1m -t 5s
```
With Docker:
```sh
docker run --rm -i -v /path/to/config.json:/config.json aykhans/dodo -f /config.json -u https://example.com -m GET -d 10 -r 1000 -o 1m -t 5s
```
