pasty

Pasty is a fast and lightweight code pasting server

Installation

You may set up pasty in multiple different ways. However, I won't cover all of them as I want to keep this documentation as clean as possible.

1.) Building from source

To build pasty from source make sure you have Go installed.

1. Clone the repository:

git clone https://github.com/lus/pasty

2. Switch directory:

cd pasty/

3. Run go build:

go build -o pasty ./cmd/pasty/main.go

To configure pasty, simply create a .env file in the same directory as the binary is placed in.

To run pasty, simply execute the binary.

2.) Docker (recommended)

To run pasty with Docker, you should have basic understanding of it.

An example docker run command may look like this:

docker run -d \
    -p 8080:8080 \
    --name pasty \
    -e PASTY_AUTODELETE="true" \
    ghcr.io/lus/pasty:latest

Pasty will be available at http://localhost:8080.
