## Containers
## Running Locally with Docker
If you would like to try out CyberChef locally you can either build it yourself:
**Prerequisites**
- [Docker](https://www.docker.com/products/docker-desktop/)
- Docker Desktop must be open and running on your machine
#### Option 1: Build the Docker Image Yourself
1. Build the docker image
```bash
docker build --tag cyberchef --ulimit nofile=10000 .
docker run -it -p 8080:80 cyberchef
```
2. Run the docker container
```bash
docker run -it -p 8080:8080 cyberchef
```
3. Navigate to `http://localhost:8080` in your browser
Or you can use our image directly:
#### Option 2: Use the pre-built Docker Image
If you prefer to skip the build process, you can use the pre-built image
```bash
docker run -it -p 8080:80 ghcr.io/gchq/cyberchef:latest
docker run -it -p 8080:8080 ghcr.io/gchq/cyberchef:latest
```
Just like before, navigate to `http://localhost:8080` in your browser.
This image is built and published through our [GitHub Workflows](.github/workflows/releases.yml)
