Installation

Using Docker (Recommended)

Pull the latest Dodo image from Docker Hub:

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:

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:

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 section.

Building from Source

To build Dodo from source, ensure you have Go 1.24+ installed.

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:

dodo -u https://example.com -m GET -d 10 -r 1000 -o 1m -t 2s

With Docker:

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:

    # 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"]

3. CLI & Config File Combination

CLI arguments override config file values:

dodo -f /path/to/config.yaml -u https://example.com -m GET -d 10 -r 1000 -o 1m -t 5s

With Docker:

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
