## 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:
#### 2.1 YAML/YML Example

- key1: "value"
# A random value will be selected from the list for param "key2" on each request
# e.g. "?key2=value2"
- key2: ["value1", "value2"]

- key1: "value"
# A random value will be selected from the list for cookie "key2" on each request
# e.g. "key2=value1"

- "socks5h://example.com:8080"
```
```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
```
You can find more usage examples in the [EXAMPLES.md](./EXAMPLES.md) file.
## Config Parameters Reference

## Template Functions
Dodo supports template functions in `Headers`, `Params`, `Cookies`, and `Body` fields. These functions allow you to generate dynamic values for each request.
You can use Go template syntax to include dynamic values in your requests. Here's how to use template functions:
In CLI config:
```sh
dodo -u https://example.com -r 1 \
-header "User-Agent:{{ fakeit_UserAgent }}" \ # e.g. "User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko)"
-param "username={{ strings_ToUpper fakeit_Username }}" \ # e.g. "username=JOHN BOB"
-cookie "token={{ fakeit_Password true true true true true 10 }}" \ # e.g. token=1234567890abcdef1234567890abcdef
-body '{"email":"{{ fakeit_Email }}", "password":"{{ fakeit_Password true true true true true 10 }}"}' # e.g. {"email":"john.doe@example.com", "password":"12rw4d-78d"}
```
In YAML/YML config:
```yaml
headers:
- User-Agent: "{{ fakeit_UserAgent }}" # e.g. "User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko)"
- "Random-Header-{{fakeit_FirstName}}": "static_value" # e.g. "Random-Header-John: static_value"
cookies:
- token: "Bearer {{ fakeit_UUID }}" # e.g. "token=Bearer 1234567890abcdef1234567890abcdef"
params:
- id: "{{ fakeit_Uint }}" # e.g. "id=1234567890"
- username: "{{ fakeit_Username }}" # e.g. "username=John Doe"
body:
- '{ "username": "{{ fakeit_Username }}", "password": "{{ fakeit_Password }}" }' # e.g. { "username": "john.doe", "password": "password123" }
- '{ "email": "{{ fakeit_Email }}", "phone": "{{ fakeit_Phone }}" }' # e.g. { "email": "john.doe@example.com", "phone": "1234567890" }
- '{{ body_FormData (dict_Str "username" fakeit_Username "password" "secret123") }}' # Creates multipart form data for form submissions, automatically sets the appropriate Content-Type header.
```
In JSON config:
```jsonc
{
"headers": [
{ "User-Agent": "{{ fakeit_UserAgent }}" }, // e.g. "User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko)"
],
"body": [
"{ \"username\": \"{{ strings_RemoveSpaces fakeit_Username }}\", \"password\": \"{{ fakeit_Password }}\" }", // e.g. { "username": "johndoe", "password": "password123" }
"{{ body_FormData (dict_Str \"username\" fakeit_Username \"password\" \"12345\") }}", // Creates multipart form data for form submissions, automatically sets the appropriate Content-Type header.
],
}
```
For the full list of template functions over 200 functions, refer to the `NewFuncMap` function in `utils/templates.go`.
