Docker

Dolos provides already built public Docker images through Github Packages. To execute Dolos via Docker, use the following command:

docker run ghcr.io/txpipe/dolos:latest

The result of the above command should show Dolos' command-line help message.

Entry Point

The entry-point of the image points to Dolos executable. You can pass the same command-line arguments that you would pass to the binary release running bare-metal. For example:

docker run -it ghcr.io/txpipe/dolos:latest --help

For more information on available command-line arguments, check the usage section.

Using a Configuration File

The default daemon configuration file for Dolos is located in /etc/dolos/daemon.toml. To run Dolos in daemon mode with a custom configuration file, you need to mount it in the correct location. The following example runs a docker container in background using a configuration file named daemon.toml located in the current folder:

docker run -d -v $(pwd)/daemon.toml:/etc/dolos/daemon.toml \
    ghcr.io/txpipe/dolos:latest daemon

Versioned Images

Images are also tagged with the corresponding version number. It is highly recommended to use a fixed image version in production environments to avoid the effects of new features being included in each release (please remember dolos hasn't reached v1 stability guarantees).

To use a versioned image, replace the latest tag by the desired version with the v prefix. For example, to use version 0.8.0, use the following image:

ghcr.io/txpipe/dolos:v0.8.0

Multiple Architectures

Dolos docker image is multi-arch, meaning that it can be used from different CPU architectures. We currently support amd64 (aka x86_64) and arm64.

The Docker daemon will detect your architecture and use the correct manifest to run the image. The usage procedures are the same regardless of the architecture.
