# Docker Guide
|
|
|
|
There are two ways to obtain a Lighthouse Docker image:
|
|
|
|
1. [Docker Hub](#docker-hub), or
|
|
2. By [building a Docker image from source](#building-the-docker-image).
|
|
|
|
Once you have obtained the docker image via one of these methods, proceed to [Using the Docker
|
|
image](#using-the-docker-image).
|
|
|
|
## Docker Hub
|
|
|
|
Lighthouse maintains the [sigp/lighthouse][docker_hub] Docker Hub repository which provides an easy
|
|
way to run Lighthouse without building the image yourself.
|
|
|
|
Obtain the latest image with:
|
|
|
|
```bash
|
|
$ docker pull sigp/lighthouse
|
|
```
|
|
|
|
Download and test the image with:
|
|
|
|
```bash
|
|
$ docker run sigp/lighthouse lighthouse --version
|
|
```
|
|
|
|
If you can see the latest [Lighthouse release](https://github.com/sigp/lighthouse/releases) version
|
|
(see example below), then you've successfully installed Lighthouse via Docker.
|
|
|
|
> Pro tip: try the `latest-modern` image for a 20-30% speed-up! See [Available Docker
|
|
> Images](#available-docker-images) below.
|
|
|
|
### Example Version Output
|
|
|
|
```
|
|
Lighthouse vx.x.xx-xxxxxxxxx
|
|
BLS Library: xxxx-xxxxxxx
|
|
```
|
|
|
|
### Available Docker Images
|
|
|
|
There are several images available on Docker Hub.
|
|
|
|
Most users should use the `latest-modern` tag, which corresponds to the latest stable release of
|
|
Lighthouse with optimizations enabled. If you are running on older hardware then the default
|
|
`latest` image bundles a _portable_ version of Lighthouse which is slower but with better hardware
|
|
compatibility (see [Portability](./installation-binaries.md#portability)).
|
|
|
|
To install a specific tag (in this case `latest-modern`) add the tag name to your `docker` commands
|
|
like so:
|
|
|
|
```
|
|
$ docker pull sigp/lighthouse:latest-modern
|
|
```
|
|
|
|
Image tags follow this format:
|
|
|
|
```
|
|
${version}${arch}${stability}${modernity}
|
|
```
|
|
|
|
The `version` is:
|
|
|
|
* `vX.Y.Z` for a tagged Lighthouse release, e.g. `v2.1.1`
|
|
* `latest` for the `stable` branch (latest release) or `unstable` branch
|
|
|
|
The `stability` is:
|
|
|
|
* `-unstable` for the `unstable` branch
|
|
* empty for a tagged release or the `stable` branch
|
|
|
|
The `arch` is:
|
|
|
|
* `-amd64` for x86_64, e.g. Intel, AMD
|
|
* `-arm64` for aarch64, e.g. Raspberry Pi 4
|
|
* empty for a multi-arch image (works on either `amd64` or `arm64` platforms)
|
|
|
|
The `modernity` is:
|
|
|
|
* `-modern` for optimized builds
|
|
* empty for a `portable` unoptimized build
|
|
|
|
Examples:
|
|
|
|
* `latest-unstable-modern`: most recent `unstable` build for all modern CPUs (x86_64 or ARM)
|
|
* `latest-amd64`: most recent Lighthouse release for older x86_64 CPUs
|
|
* `latest-amd64-unstable`: most recent `unstable` build for older x86_64 CPUs
|
|
|
|
## Building the Docker Image
|
|
|
|
To build the image from source, navigate to
|
|
the root of the repository and run:
|
|
|
|
```bash
|
|
$ docker build . -t lighthouse:local
|
|
```
|
|
|
|
The build will likely take several minutes. Once it's built, test it with:
|
|
|
|
```bash
|
|
$ docker run lighthouse:local lighthouse --help
|
|
```
|
|
|
|
## Using the Docker image
|
|
|
|
You can run a Docker beacon node with the following command:
|
|
|
|
```bash
|
|
$ docker run -p 9000:9000/tcp -p 9000:9000/udp -p 127.0.0.1:5052:5052 -v $HOME/.lighthouse:/root/.lighthouse sigp/lighthouse lighthouse --network mainnet beacon --http --http-address 0.0.0.0
|
|
```
|
|
|
|
> To join the Prater testnet, use `--network prater` instead.
|
|
|
|
> The `-p` and `-v` and values are described below.
|
|
|
|
### Volumes
|
|
|
|
Lighthouse uses the `/root/.lighthouse` directory inside the Docker image to
|
|
store the configuration, database and validator keys. Users will generally want
|
|
to create a bind-mount volume to ensure this directory persists between `docker
|
|
run` commands.
|
|
|
|
The following example runs a beacon node with the data directory
|
|
mapped to the users home directory:
|
|
|
|
```bash
|
|
$ docker run -v $HOME/.lighthouse:/root/.lighthouse sigp/lighthouse lighthouse beacon
|
|
```
|
|
|
|
### Ports
|
|
|
|
In order to be a good peer and serve other peers you should expose port `9000` for both TCP and UDP.
|
|
Use the `-p` flag to do this:
|
|
|
|
```bash
|
|
$ docker run -p 9000:9000/tcp -p 9000:9000/udp sigp/lighthouse lighthouse beacon
|
|
```
|
|
|
|
If you use the `--http` flag you may also want to expose the HTTP port with `-p
|
|
127.0.0.1:5052:5052`.
|
|
|
|
```bash
|
|
$ docker run -p 9000:9000/tcp -p 9000:9000/udp -p 127.0.0.1:5052:5052 sigp/lighthouse lighthouse beacon --http --http-address 0.0.0.0
|
|
```
